Hi,
using java script can write like this

How to do validation of input fields

Hi all,
I have a rquirement to do the validation of input fields.Can anybody explain me how to go for that???Please explain in detail.U can also give me a link where i can find the tutorial for doing this.

Hi Amit,
What everyone has said above is correct - in the method of your action simply test for whatever condition you need to validate for. However, the following tutorial shows you how to use Web Dynpro's Message Manager to display the messages on the screen in an easy user-friendly way:
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/wd%20java/wd%20tutorials/a%20simple%20input%20form%20with%20message%20and%20error%20service%20support.pdf">Enabling Message and Error Support</a>
In addition, there are some validations that are done automatically depending on what you have your input fields set to - for instance, if you bind your input field to a date and a user enters words into the field instead of an actual date, it will automatically display an error message. To learn how to turn this feature on and off, see this tutorial

Error in validation an input field in a table ui and high lighting the cell

Hello All,
I have a table ui in one of my application.   This table has, say 6 columns; out of these 6 columns 4 columns are shown as input fields. User needs to put in some numbers in two of the fields. I need to capture these two number fields data and subtract one from the other. If number is negative , I need to let the user know by error message that the number is negative and they need to fix their input to make the answer positive. I am able to do all this, but I am not able to high light the corresponding field which needs to be fixed. Is there anyway I can do that...I mean high light the particular field as one gets it when we use the "report attribute error message" method of message manager class.
Secondly I can not halt the application, I need to do some work around for that using some flags. Is there a simple way to halt the application, other than using flags and if condition? I searched this forum, but could not find any definite answer....
Thanks very much!
Any help would greatly be appreicated.

Hi....
First you should have the table values in an internal table.... for that yo need to get the values from the context like this....
*DECLARE INTERNAL TABLE AND WORKAREA.
data ls_nd_stru type wd_this->element_<node name>
data lt_nd_table type wd_this->elements_<node name>
get all declared attributes
lo_nd_<your context node>->get_static_attributes_table(
                                           importing
                                           table = lt_nd_table ).
*now your lt_nd_table will have the values.....what ever you have in the table.
*then
loop at lt_nd_table into ls_nd_stru.
<.....your logic.....>
<ie., read the current line of the field like
ls_nd_stru-<field name1> = ls_nd_stru-<field name2> - ls_nd_stru-<field name3>
then check error msg... based on your postive or negative values
endloop.
Hope this will help you....
Thanks & regards

Javascript to copy input fields to another input field..

Hi,
I have Permanent address fields(input text fields) (address line 1,2,city, state , country,zip code) and present address fields with same input fields as premanent address
and i have a check box is present address different with value Y when checked and N when unchecked
so based on the check box checked and unchecked the permanent address should copy to present address.
i dont know how to use java script in adf
so some one please help me to do this.
thanks in advance
cheers

Hi Suchith,
I will tell you how to achieve your case using the framework itself;
1.- Add to your checkbox a setPropertyListener for each field you want to copy. So for the first one addressLine1 I assume the component value resides in your binding layer, you do
from=#{bindings.yourCheckBox.inputValue eq 'Y' ? bindings.addressLine1.inputValue : null}
to=#{bindings.otherAddressLine1.inputValue}
type='valueChange'
And the same for each field. All in the checkbox component.
Since this is a business rule, you should always aim to write this kind of logic in the model layer so you can create a method in your ViewObjectRowImpl named copyAddress() and in there you copy the values from one field to another field. Then you expose this method in the client interface and execute it when clicking the checkbox. Add autosubmit=true and partialTrigger to the panel containing your other fields to be refreshed.
Once again I am making a lot of assumptions about your model, but that is why you always need to first state the version of your JDeveloper, then give a clue about your model and where are the fields being stored and so on. So people can help you better.

Validating monetary input fields

Hi. We are developing a web site that supports English and French. Some of the web pages have forms where the user must enter monetary values. Since English and French monetary values use different formats, I am wondering if there's a Java API (that hasn't been deprecated or is obsolete) that would perform validation of these monetary values for us rather than us having to write these from scratch (granted, it would not be overly difficult)? I looked through the Internationalization tutorial but did not see anything on processing currency input, just on output formatting based on the locale (which works fine for us). Thanks...

When I run the following program:
import java.text.NumberFormat;
import java.text.ParseException;
import java.util.Locale;
public class frmoney
    public static void main(String[] args)
     String number = (args.length < 1) ? "24,98" : args[0];
     NumberFormat nfc = NumberFormat.getCurrencyInstance(Locale.FRENCH);
     try {
         System.out.println("Parsing " + number);
         System.out.println(nfc.parse(number));
     catch (ParseException e)
         System.out.println(e);
}I get:
Parsing 24,98
java.text.ParseException: Unparseable number: "24,98"

Input field validation in a Table based on the value of other column

Hi all
I have a table with 2 columns. column1 is of text view and column2 is Input field.
The user should not be allowed to enter a value in the column2 ( input field) greater than the value populated in column1(textview).
So for Eg; if the column1 is populated with value 100, The user should not be able to enter a number greater than 100 in the column2 input field.
Please let me how this can be achieved.
I appreciate the help.
Thanks

Hi,
Let me make sure u r working with table control.
First u have to create a event(VALIDATE) to do the validation.
Inside the event,
1. First get the current index where user has pointed the curson
2. Once u get the index read the internal table with index value.
3. Now u can compare the col1 and col2 values and populate the error message.
1. DATA : lo_elt TYPE REF TO if_wd_context_element,
l_index type i.
lo_elt = wdevent->get_context_element( name = 'CONTEXT_ELEMENT' ).
CALL METHOD LO_ELT->GET_INDEX( RECEIVING MY_INDEX = l_index.
above code should be written inside the event.
Thanks,

Validation of values in an input field.

Hello togther,
I've created an input field with a value-selector, so that the user can choose a value from help-list. But he can also enter a value directly into the input field. Is there any "STANDRAD" method to check whtether the value which is in the input field is valid against the values from the value-selector?
I've found a standard method to check whether mandatory fields are field and the method works fine. Is there anything like this also for checking values against values from the selector?
Thanks in advance.
Greetings,
Florian

Hello Florian,
You can create an event CHECK_DATA for OnEnter event of you input field.
Then go to the Action tab and select the action type as Validation-Independent .
Hope this will work for the input field with OVS help .

Validating Input field in Web Dynpro

Hi All,
Could you please tell me how do I use set_attribute and get_attribute methods to get the user input from the dynpro screen?
The user enters some data in the input field. I need to get this data and validate it.
Please tell me how to get the user input.
Thanks & Regards,
Srilakshmi B

hi,
you can go through it,might be your problem solve.
Example for Using Messages
The following example shows how you can use messages created in the Message Editor. In the example, both messages with static text and messages that are dependent on user inputs that is, messages with dynamic text are defined.
Description of Example
Users can create a domain in this sample application. They can then enter a number in the next input field and press Click here to validate. If the specified number lies in the previously specified range, the user is informed of this fact in a standard message. If the number does not lie within this domain, the user sees a warning message.
Prerequisites
You have created a Web Dynpro application and defined view MainView within a Web Dynpro component.
Procedure
Creating the View
Define the view as illustrated below:
Context Creation:
The context that provides the data is created as follows:
       1.      Create a context node, UIElem
       2.      Set the propertycardinality to 1..1 for the context node.
       3.      Create the context attributes a, b, and TypeField.
       4.      Set the Type of the context attributes to Integer.
Data Binding
To make the messages dynamic with regard to specification of the domain, the user inputs have to be saved. To do this, the input fields have to be bound to the context.
sss
Object
Object ID
Data Binding to Attribute
Path Within the Context Structure
a
Input Field
A
MainView.UIElem.a
b
Input Field
B
MainView.UIElem.b
Children_2
Input Field
TypeField
MainView.UIElem.TypField
In addition, bind the Children_3 pushbutton to action ValidateAction, which you also have to create.
Creating Messages in the Message Pool
The Web Dynpro tools provide a special message editor for defining messages of different types.
A message is defined by a specified key, message type, and message text. The message types error, warning, and standard are predefined.
Create the following messages:
Messages Defined in the Message Editor
Message Key
Message Type
Message text
key1
warning
Please enter a number between the range of and !
and are placeholders for the user input (the domain), which changes dynamically.
key2
standard
The value entered is within the valid range.
Implementation
Because the messages are only displayed when the user Chooses Click here to validate, the messages must be implemented in the method onActionValidateAction:
Implementierung der Methode onActionValidateAction()
//@@begin imports
import com.sap.tc.webdynpro.progmodel.controller.MessageManager;
import com.sap.test.errorhandlingtest1.wdp.IMessageErrorhandlingTest1;
import com.sap.test.errorhandlingtest1.wdp.IPrivateMainView;
//@@end
public void onActionValidateAction(
                       com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent)
    //@@begin
   int i = wdContext.currentUIElemElement().getTypField();
   int a = wdContext.currentUIElemElement().getA();
   int b = wdContext.currentUIElemElement().getB();
   MessageManager msgMgr =
         (MessageManager)wdThis.wdGetAPI().getComponent().getMessageManager();
   if (a < i && i < b)
         msgMgr.reportMessage(IMessageErrorhandlingTest1.KEY2, null, true);
   else
         Object[] arg ={new Integer(a), new Integer(b)};
         msgMgr.reportMessage(IMessageErrorhandlingTest1.KEY1, arg, true);
    //@@end
The following tasks have been implemented in this method:
       1.      Read user inputs:
int I = wdContext.currentUIElemElement().getTypField();
int a = wdContext.currentUIElemElement().getA();
int b = wdContext.currentUIElemElement().getB();
1.       Read messages from the Message Manager:
MessageManager msgMgr =
             (MessageManager) wdThis.wdGetAPI().getComponent().getMessageManager();
2.       Does the input lie within the defined domain?
if (a < i && I < b)
3.       Call the standard message when the input lies within the domain:
MsgMgr.reportMessage(IMessageErrorhandlingTest1.KEY2, null);
Method reportMessage can be used to read the messages from the Message Manager. In this way you define the key and the objects that you want to change dynamically in the messages. Because no dynamic text was defined in your standard messages, you define null as a parameter.
4.       Call the warning messages when the input does not lie within the domain:
Object[] arg ={new Integer(a), new Integer(b)};
MsgMgr.reportMessage(IMessageErrorhandlingTest1.KEY1, arg);
Because the warning messages ( Please enter a number between the range of and !) contain text that depends on the user input, you also have to define the parameters for the domain in an object array. In the messages, the first object is then called from the array with (and the second with , and so on).
Result
After you have built and deployed your application, you can call it by choosing Run.
If the user enters a number that lies within the defined domain, a standard message is displayed:
If the user enters a number that does not lie within the defined domain, a warning message is displayed:

HTMLB .. Input field event handling..

Hi guys,
I have a input field htmlb in my jsp. I have to handle on blur event for this.. i.e if a user gives in somethin in the input field and once it looses focus, a event should get triggered. And probably in my case it will be helpful for me if I have this event handler method in the dynpage. For this kind of event handling what should I write in the followin tag
<htmlb:inputfield id="" value="" width=""> plz tell me a tag attribute which supports this event.
Regards,
PP.

Hi Priyanka,
You can get reference of your input field in JSP into DynPage. Do like this:
Declare input field in JSP
<hbj:inputfield id="input" value="test">
In DynPage, get refernce of the input field
Wherever you want to trigger event
InputField myInputField =(InputField) getComponentByName("input");
myInputField.setClientEvent();
Hope this helps.
regards,
Siva
Note: If you get success, please post the solution before you close this thread.

Please Help. How to access to an input field in a table with javascript

Hi
i�m trying to access to the content of an input field that is in an table with a javascript function in this way
function Valida_Tabla()
var centro = document.getElementById("form1:idcentro").value;
alert("Centro es ["+centro+"]")
var des = document.getElementById("form1:table1:0:textField2").value;
alert("des ["+des+"]")
The fisrt alert is ok and displays the value of a field that is in a table.
The second alert is not displayed.
Is the syntax wrong?
what i�m doing wrong
Please help

The best bet is to look at the source of the generated HTML and then use the exactly generated ID in the HTML source. When I looked at the HTML source I see the ID of a textfied inside a table as
form1:table1:tableRowGroup1:0:tableColumn1:textField1

Input Data Validation Of A Field Associated To A Check Table

Hello,
Does Web Dynpro have an inherent functionality to validate input fields associated to a check table?
For example I created a structure with the field UNAME and defined USR02 as the check table for it. And then I defined a UI InputField in my View and bind it to UNAME. Web Dynpro does NOT seem to do an automatic validation to check if the value entered by the user exists in USR02.
Is there an interface or class that can be called in method WDDOBEFOREACTION to do the validation. Or do we just have to do some manual validation using SELECT statements?
Thanks.
Giscard

Hi Giscard,
Web Dynpro does automatic validation when you assign the check table .
You need not write any code as such.
If the data which you entered is incorrect ,when you are trying to perform any action(like saving the data in data base or performing any further action with the wrong data that ia entered )
the system throws an error message as"USERNAME -
NOT IN THE SYSTEM'.

Priya
