Numeric field limit length to visible area

I have a pdf saved as Dynamic XML Forms with a numeric field checked to limit length to visible area, but the "limit to visible area" option does not work. If save the same pdf as Static Form works fine.
Can someone provide an example or tell me how to solve it?
Thanks in advance

In the change event you can place the following script (Java Script)
if(xfa.event.newText.length >maxLength)xfa.event.change = "";
Replace the "maxLength" with the maximum numbers you want the user to enter..
This way it can stop the user to enter more characters after reaching the maxLength.

Display pattern of numeric field in adobe reader ver 8 and 9.

I have added a text field to my form and have set the following properties:
Type: Numeric field
Limit length to visible area: checked (so that it accepts upto 9 digits)
display pattern: zzz9
data pattern: zzz9
data format: Integer
When I type "123456789" in the field, adobe reader version 7 and 9 are adding commas to the number and are displaying it as "123,456,789" while adobe reader 8 displays it the way i want "123456789"
Appreciate if someone can quickly provide some guidance here.

The issue is that the pattern that you are applying from the field cannot be applied to your input so the default pattern for numeric fields is being applied (hence the 123,456,789). If you make sure that your numeric field is set for integer (Binding tab/Data Format). Then set the display pattern to num{zzzzzzzz9}. It will work.
The default pattern is held in the XDP template. It is created based on your locale. If you click on the XML Source tab (between Preview and Master Pages - if it is not visible then you can make it visible on the View/XML Source menu)then do a serach ctrl-F for numberPattern you will see where it is defined in the template. If you modify this one then it will only be applied for this form. Any new forms will revert back to the old pattern.

Limit the number of digits in a numeric field

Hi
I have been searching for the last hour to find out ho i can limit the numeric field on my livecycle form. I have seen lots of java script however nothing seems to work, all i want is for the user only to enter 6 digits (e.g. 123456) and if they try to enter more a message would say that only a 6 digit number can be entered.
This is driving me mad for something i though would be quite simple.
Can anybody help?

I am not 100% on the Javascripting; however in the Object window, Field Section there is an option to put the maximum number of characters in a numeric field. It says "comb of" and then it gives you an option of the maximum number of characters that can be allowed in the field. If you put 6 it will only allow 6 characters. However if that is not something you want you can go to the Value Section within the Object Window and click on the Validation Pattern button. In the Validation tab, in the pattern section type in "999999" and hit apply. It should replace it with "num{999999}" which is 6 numeric values. For a custom error message, in the same Value section, add a custom Validation Pattern Message (make sure to check the error box") and then save your file. If someone tries to put more than 6 values in it should pop up with your custom message. I do find it is easier for the user to understand if you use the comb function instead of the validation pattern. It is a lot more clear to the user on what you need. Just my personal opinion though.

Numeric Field - length

Hello!
Can someone tell me why I can´t get the lenght of a numeric field like this: field.rawValue.length
This seems a simple thing to do, however, I can get the length of the data... There is a rawValue because I can see it using app.alert.
Thank you

You could use:
> NumericField1.rawValue.toString().length
or
> (new String(NumericField1.rawValue)).length
Javascript is an untyped scripting language, but sometimes it gets a little confused and you have to give it a little prod.
You may have to do some checking before using these methods, to make sure the rawValue is not null etc, prior to using these methods.
This is a good description of the use of this method:

Connecting selection of radio button to a text or numeric field

Hi. I am using LiveCycle Designer 8.0 and I am trying to define object properties that will allow the selection of a radio button to populate in a numeric data field at the bottom of the page. I was able to write the script to have that happen with drop-down lists, but I can't figure out how to write the script for the radio button. I also don't know if the script is supposed to apply to the radio button itself or the numeric field where I want the result to show-up. Can you please help me with some sort of an example script? Thanks.

Hi Jen,
I would recommend that you amend your workspace in Designer. You can show/hide palettes from the Window menu.
Here are some pointers (which are optional):
This is the hierarchy palette and is very handy when working with forms. You can select objects quickly and drag objects around.
This is the Object palette, which makes it easy to drag objects onto the page.
The main space with tabs for Design View, Master Pages, XML Source (you should not need this) and Preview.
You can select objects in EITHER the page or the hierarchy view and then change properties in other palettes.
The Script Editor is very important when you start to add functionality to your form. It is visible on your screen shot, but it is limited to one line in height. So I would recommend that you drag this down so that you can see a few lines of script. The Show dropdown in the Editor allows you to look at the script in various events. In the example I posted, there is script in the click event.
Object palette (and Font & Paragraph palettes). These will allow you to make changes to various properties, depending on the object that is selected.
You will see from the screenshot that you can position and stack the palettes to suite your screen and workflow.
Now, in relation to your screenshot:
You have selected a single radio button in your group. You need to select the whole exclusion group, this is easy in the hierarchy palette.
In the Object > Binding palette you have ticked the Specify Item Values (good), but you need to edit the values to match the Display Items. For example for item "$85", the specified value should be "85".
For starters, I would recommend that you open a few of the palettes and then have a look at my example and the screenshots. Hopefully that will clear it up for you.

Changing width of a numeric field

Hi,
I have a table with numeric fields in the table cells.
I want it to look like this:
Item1 (numeric field box) %
Item2 (numeric field box) %
Item3 (numeric field box) %
Item4 (numeric field box) %
I can't seem to limit the lenght of the field from the right small enough to fit 2 characters, it snaps to the width of the table cell. Then I want to put the % symbol after the field.
You can move the field smaller from the left though.
I tried to split the table cell, but when I select in the table cell, it just selects the numeric field and the options for splitting the table cell are grayed out under the table menu?
Thanks!

Somehow on your form it worked in another way than in mine.
Put this javascript on exit:
if (this.rawValue > 100 || this.rawValue < 1)
{this.rawValue = null;}
if (this.rawValue <= 100 && this.rawValue >= 1)
{this.rawValue = this.rawValue / 100;}
this one on enter:
if (this.rawValue != null && this.rawValue <= 1)
this.rawValue = this.rawValue * 100;
this pattern on the first heading (or whatever it is called):
num{z9%}
and this pattern on the second:
num{zz}
If the user enters anything that is no integer between 1 and 100 it will delte the value. (You won't need to prohibit anything with the lenghts of the field.)
Edit: If you want you can also add a error message which tells the user that the number he has to write into it has to be between 1-100.

Adobe changes my numeric field to include commas when validation fails

Adobe changes my numeric field to include commas when validation fails. My numeric validation setting is num{zzzzzzz9.99}. I want my numeric field to display as 99999999.00, no commas and only to have 2 decimals places. I added this validation to the Display, Edit, Validation and Data tabs under the validation pattern dialog box.
When validation fails, adobe changes the display of the field to include commas and drops the decimal places:
999,999,999
How can I prevent this from happening? Any feedback is greatly appreciated.
I've also added a change event to the field as well:
\\only allows numbers and period.
if (xfa.event.newText.match(/[^0-9.]/))
xfa.event.change = "";
\\only allows 11 characters to be entered.
var maxLength = 11;
if(xfa.event.newText.length >maxLength)xfa.event.change = "";

I want it to display only numbers followed by 2 decimal places.
999999999.00
If I type all numbers in my field like 999999999999 and I go over the character limit of 11. My validation fails and then my numeric field is displayed with commas, 999,999,999 without the 2 decimal places. Is there a way to prevent adobe from automatically changing my fields?

Large numeric field in a .csv file will not display

A .csv file contains a numeric field which in some rows contains an 11-digit number (like 14024583126). These will not display (blank or null). Some of the rows contain numbers of 5-digits or 7-digits and these display fine. How can I get the 11-digit numbers to display correctly?
I have no capability to change the .csv file to make this field type as string. Would there be a way to convert the numeric field to string?

Thank you for the formula. However, the string field displays just like the numeric field did. If the numeric value in the row is a 5-digit or 7-digit number it converts to text and displays fine. But if the numeric value in the field is an 11-digit number nothing is displayed after conversion to text. The numeric field must have some limit on what the size can be. How can we get around that limitation?
FYI - the data I'm trying to process is a dump of monthly Call Detail Records from Cisco's Unified Communications Manager. The 11-digit number is a Long Distance Number like 14021234567 (ex., 1-402-123-4567). The 5-digit numbers are VoIP extension numbers while the 7-digit numbers are local calling numbers.

Regular Expression for floating point numeric field

Hi,
the requirements for the field are as follows:
- floating point numeric field 7 digits in length
- the field must contain a decimal (dot) and either one, two or three digits to the right of the decimal
- (leading zeroes are required if needed to fill up the 7 characters)
My example shown below does not check for the length of 7 characters:
public static void main(String[] args) {
    String str = "04100.0";
    System.out.println(str);
    Pattern f_1To7 = Pattern.compile("^([0-9]*\\.[0-9]{1,3})$");
    Matcher matcher = f_1To7.matcher(str);
    if (matcher.find()) {
        // yes, we've found something
        System.out.println("We matched the pattern!");
    } else {
        System.out.println("Better luck next time!");
}When changing the pattern to
^([0-9]*\\.[0-9]{1,3}){7}$the whole expression will be repeated 7 times - but I would like to have to whole String to be 7 characters long.
Here are some examples for the field:
050.500 or 04100.0Thanks a lot and best regards,
- Stephan

...Assuming that you are going to use Java*, you could use a lookahead at the start of your regex:

Test limits in numeric field in case value is written by property node

Hello,
maybe its possible to integrate this feature:
If I have an numeric input field with defined limits (e. g. 0 = minima, 5 = maxima, step = 1, coerce all on).
Now I write a number in this field and Labview correct the input into the limits.
In case I write a number by property node "value", the limits doesn't matter.
I have to test the limits manually before writing in the numeric field by read out the limit properties and so on....

I figure out that when the value is changed using the property "Value", the coercing process work as expected. For the property "Val(Sgnl)" the limits are ignored. This is on purpose?
I made a small program to test it. If the "input" is placed in a value out of range and "Signaling" is turned on and off couple times, the "output" stays or of range! Or i'm missing something or there something really strange here.

Numeric field with restriction of 8 digits

Dear All.
How should i restrict a numeric field with 8 digits length? (without any default validation message).
Thanks,.
VJ.

Hi,
you can use a small JavaScript in the fileds change event to limit the length to 8 characters.
if (xfa.event.fullText.length > 8) {
xfa.event.change = "";

What is the initial value for a numeric field ??

Can someone tell me what the INITIAL VALUE FOR A NUMERIC FIELD is ?? Thank you
Rod.

Using the following...
   class MyClass
     int myvar1; // Default initial value
     int myvar2 = 3; // Default initial value and default value
     MyOtherClass myclass1; // Default initial value
     void doit()
       int mylocal1; // No value
       MyOtherClass myclass2; // No value
All number member variables, like myvar1 start off with andefault initial value which is zero. For booleans this is false. Object reference variables, like myclass1, have a null value.
All local numeric variables are considered undefined. So mylocal1 and myclass2 are undefined. Before you can use them you must explicitly provide a value.
Finally note that myvar2 will have two values during class instantiation. Initially it will have a value of zero. Sometime later it will have the value of 3. (When that happens is very definitely outside the scope of what this forum covers. If you want to know then ask in the advanced forum.)

Null values in Numeric fields of Datasets

I am wondering if anyone has run into this problem before and
checking to see if anyone has an elegant solution.
I have a rather large data set. (actually 5 of them on a
single page) I am sorting certain columns in a table as numbers so
i assign the variable " ds1.setColumnType("somenumbercolumn",
"number")" In most cases Spry works great and it sorts by numbers
properly. The problem is some of the fields in the XML file are
null and I am trying to sort them as a number. Spry actually
adjusts for this (as far as i can tell) and treats them like a 0
which isn't exactly ideal considering there are real zero values in
the data. I know spry doesn't currently format numbers:
So here is my question. Does anyone one have a solution to
fixing null values in a table so that it is still sortable but
doesn't display a "0" and instead displays something like "--" or
whatever. I have the option of editing the XML file as well, but I
still need the table to sort by number.
If not null values, how about non numeric fields which can
still be sorted in a numeric column?

Hi,
We have an old post that raised a similar problem with yours.
The post can be found
here
For you situation, you should add an if condition for the
rows that have 0 and to add a custom string instead 0.
for (var i = 0; i < numRows; i++)
if(rows
[ "field_name"] == 0)
rows[ "field_name" ] = '--';
Hope this helps you,
Diana

How do I validate one field's length based on another field's selection?

I am creating a form for our offices where I need to check one field for length of a serial number based on the answer to a previous field's selection. Depending on the product selection, the serial number has two different lengths. Both fields are marked as required, but I want to make sure that we receive the full serial number for our product. Previous forms were done on paper and instructions were for the last 4 digits only which now we want the full serial number. One product has a 12 digit number and the other is 6.
I'm guessing that I need a validation script in the serial number field, but I am not a JavaScript coder and haven't found the right thing when searching. Any help would be great!
Thanks!

Never trust your users to follow what you expect them to do... That often leads to mistakes and problems later on.
I would reset the s/n field when a selection is made in the drop-down. To do so set the drop-down field to commit the selected value immediately and add code as its custom validation script:
this.getField("Serial Number").value = "";
To validate the s/n field you can use something like this as that field's custom validation script (of course, you'll need to adjust the field names and values to match the actual ones in your file):
event.rc = true;
if (event.value) {
     var selection = this.getField("Dropdown1").valueAsString;
     if (selection=="1" && event.value.length!=6) {
          app.alert("Error! The s/n must be 6 digits long.");
          event.rc = false;
     if (selection=="2" && event.value.length!=12) {
          app.alert("Error! The s/n must be 12 digits long.");
          event.rc = false;

Numeric field limit length to visible area
