Dynamically creating variable names in javascript

Hi.
I have to create variable names dynamically in JavaScript.
My JSP file accesses information from Database and forms a String corresponding to the information received.
This String is passed to a JAvaScript function that should CREATE a variable with that NAME.
For Ex:
My database access resulted in a single row...
id name sal
34 John Smith 38000
the resulting VARIABLE NAME should be Menu34. 34 comes from the database result.
Is there any function to dynamically create a variable name in JavaScript?
Thanks in advance.

The JSP is printing the contents of an HTML page, and Javascript code can be part of that output...
So you would just write out the stuff, something like this....
<script>
<% while(rs.hasNext()) { %>
var Menu<%= rs.getInt("id") %> = '<%= rs.getString("name") %>';
<% } %>
</script>
In the browser, it'll just look like another long list of Javascript variables.

Creating variable names?

hi all
is it possible to dynamically create variable names so you can keep track of them?
I have to generate the following code a number of times depending on a number the user has input. So ideally Id like to create
variables whose names i can keep track of for later reuse
eg horHatch1, horHatch2.... without hardcoding them in. is this possible?? are there any better ways of accomplishing this task?
this code just draws and adds labels on an x axis.
thanks
Line2D.Double horHatch1 = new Line2D.Double(horAxis.getP1().getX() + horInterval,
                                                horAxis.getP1().getY() - HatchLength/ 2,
                                                horAxis.getP1().getX() + horInterval,
                                                horAxis.getP1().getY() + HatchLength/2);
    graphics.draw(horHatch1);

hi
i used the following code
but i need to convert Line"d to Line2d.Double as explained below
for(int i=1; i<x+1; i++)
Line2D.Double horHatch1 = new Line2D.Double(horAxis.getP1().getX() + horInterval*i,
                                                horAxis.getP1().getY() - HatchLength/ 2,
                                                horAxis.getP1().getX() + horInterval*i,
                                                horAxis.getP1().getY() + HatchLength/2);
    graphics.draw(horHatch1);
     v.addElement(horHatch1);
Add text to hatches
    decorateVerticalLine(graphics, horHatch1, "M");
    decorateVerticalLine(graphics, horHatch2, "T");
decorateVerticalLine(graphics, (Line2D)v.elementAt(i), names.elementAt(nColumn).toString());
//compiler complains that (Line2D)v.elementAt(i) is not of type java.awt.geom.Line2D.Double but of   java.awt.geom.Line2Di tried :
horizontalAxisTicks[i] =((Double)(Line2D)v.elementAt(i)).doubleValue()).getX1();
but this isnt correct i dont think.
thanks

Dynamically create variables and names

Hi,
I am dealing with some software that will send
me string variables and their values. I have
to process each variable it sends me to get
its value. The problem is I dont know how many
its going to send me in advance, so I cant
hard code the varible names into my class.
At run time I will get a int. value as to the
number of variables. An array won't work and
a vector wont work cause I need to process
each variable by its name. I also know that
each variable name will be some alpha characters
followed by a number. For example:
int 6
test1
test2
test3
test4
test5
test6
The next time it could be 50 ...or 1 or any number....
Is there anyway I can get my class to dynamically
delcare String variables and their names?.......

Just use some kind of collection. If you know the alpha characters at compiletime you can use an array - instead of test1 to test6 as in you example, you'd get test[0] to test[5]. (or test[1] to test[6] if you want the numbers to match - just create the array one bigger than needed and leave the [0] unused.) If you don''t know the alpha characters you can use a HashMap or some similar collection, and use the strings "test1", "test2" etc. as keys.
You can also make your own class to handle this, for example by wrapping some code around an array to simplify access to your Strings.

Creating variable names using a counter

Hi all
I have a snippet of code that I am trying to work in Flash 6,
it is attached to this post. Inside the for loop I am trying to
define the class variable instance names dynamically using the 'i'
counter encapsulated within the eval function. Is there anyway I
can add dynamically named variables or am I just kidding myself.
regards
John Walsh
www.javono.com

I think KGlad meant to post the following, probably
accidentally did italics in bbcode
import ButtonClass;
var a:Array= new Array("alonso_btn", "gerrard_btn");
for (var i = 0; i < a.length; i++) {
this[a[ i ] = new ButtonClass();
}

Dynamically create variables when read from txt file

hi,
need a little help on this one.
im reading in the name of user defined classes from a text file into a string array. once i have them all read in i want to be able to declare instances of each class, but how?
i have the string array with the names and i know that il have to use a loop with a counter to give each instance a unique name but im stomped on how to do the rest.
anyone have any ideas?
many thanks in advance.

im getting it in the following line:
Class cls = Class.forNames(behList[ i ]);
behList is a list of names, im trying to loop through
it and create an instance of each object in the list
using
Object x = cls.newInstance();
but it never gets to this line cos of the top one.
any ideas?stupid bb codes...
now are you sure you got that error by java and not Eclipse(or another IDE)
cause afaik, if the VM cant find the class, it will throw a ClassNotFoundException...

Dynamic creating field names within Loop

Hi,
I've a record which comprises of a few key fields and then 52 qty fields, one for each week of the year. ( Not my design honest!!).
Anyway with in a Cursor there are currently 52 "IF" statements clearing out values less than the current week number. I'd tried to replace this with the following. However I'm having trouble with the " 'c1_rec.qty'| |lv_count " bit.
Has anyone got any ideas?
lv_week:=22; ( added for clarity )
lv_count:=1;
WHILE lv_count < lv_week LOOP
'c1_rec.qty'| |lv_count :=0;
lv_count:=lv_count+1;
END LOOP;
John-Paul Thompson

John-Paul;
If I understand the question correctly, you have a table with 52 columns, one for each week of the year. You are trying to zero the quantity for each week prior to the current week. I'm going to take a sab at this. Bear in mind that I have no way to debug the code.
DECLARE
c NUMBER;
n NUMBER;
v_sql VARCHAR2(2000)
lv_week NUMBER:=22; ( initialize week#)
lv_count NUMBER:=1;
BEGIN
v_sql := 'UPDATE c1_rec SET '
WHILE lv_count < lv_week LOOP
v_sql := v_sql| |
'qty'| |TO_CHAR(lv_count) | |' :=0';
lv_count:=lv_count+1;
IF lv_count < lv_week THEN
v_sql := v_sql | | ', ';
END IF;
END LOOP;
--sql := v_sql | | YOUR WHERE CLAUSE
c:= dbms_sql.open_cursor;
dbms_sql.parse(c, v_sql, dbms_sql.native)
n:= dbms_sql.execute(c);
dbms_sql.close_cursor(c);

I could use IF statements at the end of the application process to decide what BIND vairable to fill with the information the process has collected however I'd prefer just to create the BIND variable from the
name of the submitted information.
So I have an application level variable called WHICHCHART. this gets populated with text upon calling the application process...so let's say 'chart1' is what it gets filled with.
What I"d like to have at the end of the application process is just a bind variable waiting called :chart_1.
So no matter what the value of WHICHCHART it will create an on the fly a bind variable with the same name.

Ok. I guess this question was more how do you do this..then OH NO there are not other ways to do this.
So I have a page with a chart region. this chart will have 3 Y Axes which prohibits the use of the default XML.
So..
I have the following Javscript:
function getdata(whichchart) {
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=VM_XML_GENERATION',0);
        get.add('WHICHCHART',whichchart);
        gReturn = get.get('XML');
get = null;
Which is called when the page loads by a dynamic action:
getdata('production');
When the javascript is called as you can see it fires off:
declare
   chart_series_data VARCHAR(32767);
   type array_cols is varray(7) of varchar2(100);
   array array_cols := array_cols('VM_HOSTS_NUM','VM_NUMBER','VM_PHYS_MEM','VM_VIRT_MEM','VM_CPU_COUNT', 'VM_TOTAL_DISK','VM_PROVISIONED_DISK');
BEGIN
--IF :WHICHCHART IS NULL THEN
--RAISE_APPLICATION_ERROR(-20001,'Chart variable not set');
--END IF;
chart_series_data := null;
chart_series_data := '      <data>'||chr(10);
chart_series_data := chart_series_data|| '        <series name="Hosts Number" type="Line" color="0x1D8BD1" >'||chr(10);
for c1 in (SELECT VM_REPORT_DATE LABEL,VM_HOSTS_NUM from TABLE where VM_REPORT_DATE between add_months(SYSDATE,-24) and SYSDATE and lower(VM_DCNAME)=lower(:WHICHCHART) )
loop
chart_series_data := chart_series_data || '<point name="'||c1.LABEL||'" ';
chart_series_data := chart_series_data || 'y="'||c1.VM_HOSTS_NUM||'"></point> '||chr(10);
end loop;
chart_series_data := chart_series_data|| '      </series>'||chr(10)||'</data>';
:PROD_DATA := chart_series_data;
END;
The : production variable at the end of this I want to change the name of based on the value I'm sending of WHICHCHART from the javascript. I hope this is clearer now.
AGAIN this is not really a need. It is a want to be able to create dynamic bind variable names going forward.
Thanks

Dynamically create (global) variables

Hi,
Is it in anyway possible to dynamically create variables, like you can do in Forms:
DEFAULT_VALUE('test', v_test);
with v_test holding the variable, like 'GLOBAL.TEST'. Forms would then create me the variable as it doesn't exist yet, assigning the given value.
Like this I could read my variables' names from a DB table, dynamically create them, and assign their values. Inside the report I would then use them as lexical references.
I know I can create parameters inside the report achieving the same, but we need the table-approach for our translations. Getting rid of the parameters' overhead would be great!
Any suggestions appreciated,
K.

Where the lov is attached set the VALIDATE FROM LIST property to YES and craate one trigger for each field called WHEN-VALIDATE-ITEM and use the code as below...
IF GET_ITEM_PROPERTY('FORM_FIELD_NAME',ITEM_IS_VALID)='FALSE' THEN
:FORM_FIELD_NAME:=:GLOBAL.EmpCode;
END IF;
Don't forget to set NULL for global variable in KEY-LISTVAL trigger after assigning value to the form's field.
HTH.

Inventory forecast help - dynamically creating formulas?

Post Author: ddenise
CA Forum: Formula
I am writing a report that reconciles sales orders to inventory - essentially, group sales orders by the scheduled production date, list out all the parts that are needed and forecast the impact on inventory, highlighting any areas where inventory is foretasted to go negative. The results right now look like this:                               Part          In Inventory          Needed         Inventory RemainingOrder Number 567     Product Number 311187          Part Number 8111234          100                  5                  95          Part Number 8111235      Product Number 311189          Part Number 8111234          100                 6                  94
          Part Number 8112235 You can see the problem is that once I calculate "Inventory Remaining", the next instance of part 8111234, should have an "In Inventory" value of 95, NOT 100, but 100 is what is stored in the database. The next time that part number is used, the database value is pulled and 100 is displayed. A running total or summary won't work because they cannot be used on 2nd pass formulas/variables; "Inventory Remaining" is a formula evaluated on the 2nd pass.The result that I NEED to come out would be:                                Part          In Inventory          Needed         Inventory Remaining
Order Number 567
     Product Number 311187
          Part Number 8111234          100                  5                  95
          Part Number 8111235
      Product Number 311189
          Part Number 8111234          95                  6                  89
          Part Number 8112235 So.... I am thinking that I need to create a formula that does the following while records are printed:Check to see if a variable whose name is equal to the part number that is being printed (in this case "8111234") and if it doesn't exist, then create it, setting it's value to what is in the database (in this case "100")Use the variable's current value, subtract the quantity of those parts that are needed for the current record being printed and updated the variable's value to this difference.If the variable does already exisit, then use it's current value to display in the "In Inventory" column and,Use the variable's current value, subtract the quantity of those parts
that are needed for the current record being printed and updated the
variable's value to this difference.What this would do is essentially, dynamically create variables that can be used for display and other evaluation and update the particular variable that is related to the part number that is being printed. Has anyone done anything like this before? I'm sure I'm not the first to encounter this situation. Also, if there are other ways to solve this problem that Crystal can handle, please advice - I cannot seem to find any other solution. Regards,

Haha! I got all the formulas down except for the boxes but thank you so much!
I do have a new problem that just arrived, how can I get it to clear itself after I'm finished? So that it acts like a calculator and the columns are automatically cleared and the bars on hand turns into the total bars amount?
It sounds very difficult

Melissa,
I anticipated that problem and that's why I proposed the structure that I did.

Dynamic Set Variable

I am having a peculiar issue with the Set function. See the following code.
In a workflow I'm performing this code and yet it seems as though the user object is not actually ever modified.
<set name='resourcename'>
<s>server1</s>
</set>
<set name='attributename'>
<s>firstname</s>
</set>
<set name='fqname'>
<concat>
<s>user.accounts[</s>
<ref>resourcename</ref>
<s>].</s>
<ref>attributename</ref>
</concat>
</set>
<set>
<ref>fqname</ref>
<s>testvalue</s>
</set>
When I trace <ref>user.accounts[server1].firstname</ref> it returns testvalue correctly but when I check in the view it never updates the resource and does not show in the WFTrace. I'm thinking somehow that this user object is never truly updated. Anyone know of a better way to do this dynamically generated variable name?

When you check out the view are you assigning a Form?
The firstname attribute appears in the default user form and will be mapped from the global namespace. This can cause unexpected issues.
While you may not be directly using the form, if one is not assigned... it will use the default.
Create a completely empty form called myEmptyForm and add the variable Form to the checkout view with the value myEmptyForm.

Creating variables using set()

Does the set() function for dynamically creating variables
have a substitute in AS3?
This is a generic example written in AS2:

You're welcome. Until your posting, I didn't know there was
such a thing as set, so as often happens, I learn new things here.
My approach normally would have been along the lines of the = one.
If you're ever wondering about other changes, in the AS3 help
docs you can search on "Migration" and one of the few choices there
is titled as such wrt AS2. It tabulates the status of most of the
AS2 code elements and identifies alternatives for AS3 when
applicable.
Also, there's this offering you might find useful...

Creating dynamic variable names

I know there has got to a way to do this but I am not finding anything on google. I want to create a dynamic variable name like name + i so when your in a loop the names come out name1, name2 and so on till however many you want. I have tried
int name + i = 3;
int name[i] = 3; // which obviously won't but I had to try
int name{i} = 3;and I am out of ideas. Thanks for all your help.

I'd suggest using variables named j or x when posting code which uses them as array indexes.
[i] - is for italics formatting
[u] - is for underlined formatting
[code] is for class Example { ... } code formatting
etc.

JSP : create variable dynamic variable name and get his value.

//HI forums.sun.com !
//What I want to do is above :
//out.println("<td style=\"width: "+col_width_+h+" \">")
//Variable Declaration
String col_width_1 = "100px";
String col_width_2 = "150px";
//etc String col_width_N = "XXXpx";
//loop
for (int h = 0; h < hrecset.getRowCount(); h++)
//some code
//create the variable name (exemple : col_width_0 ) with the "loop counter name" to get the value
out.println("<td style=\"width: "+col_width_+h+" \">")//Do you understand what i mean?
//some code
//Variable Declaration
String col_width_1 = "100px";
String col_width_2 = "150px";
//etc String col_width_N = "XXXpx";
//loop
for (int h = 0; h < hrecset.getRowCount(); h++)
//some code
//create the variable name with a concat with the loop counter variable name to get the value of the concatened variable
out.println("<td style=\"width: "+col_width_+h+" \">")//Do you understand what i mean?
//some code

I apologize
1) Sure i understand it but i click on the "code" button after i inserted the text above but it doesn't worked now it do.
2) Because the table element need to have the total width in the HTML table TAG equal to the addition of every HTML td TAG to be W3 conform
because i have a lot of cell where i want to adjust the width.
so here my solution
<%
//Variable für Breite
String col_width_unit = "px"; // px, cm,
Integer total_table_width = 0;
String[] col_width=new String[3];
col_width[0] = "350";
col_width[1] = "75";
col_width[2] = "50";
%>
<table style="page-break-inside:avoid;width:<%=gesamt_table_width+col_width_unit%>;">
<%
for (int h = 0; h < hrecset.getRowCount(); h++)
out.println(" <td id =\"cell"+h+"\" class=\"tdall\" style=\"width:"+col_width[h]+col_width_unit+"\" >");
%>
</table>thank you very much

Assigning a 'dynamically created sequence' value to a variable

in my procedure i am creating a sequence on the fly, i am preparing the name with some passed parameters like below
v_seq_name := 'seq_'||loadid||v_table_name;
execute immediate 'CREATE SEQUENCE '||v_seq_name||' MINVALUE 1 MAXVALUE 999999999999999999999999999 START WITH 1 increment by 1 cache 20';
and now after doing some operations i need to assign the current value of sequence to a number variable i tried following but not working
1) v_curr_value : = v_seq_name.currval ;
2) select v_seq_name||'.nextval' into v_curr_value from dual;
can you please suggest me how i can get the value in plsql block.

Having said that, your architecture is probably wrong if you are dynamically creating things in a procedure.
Why do you need to create them dynamically?
