Getting a field to accept numbers only and leading zeros.

Hi StevenD,

You can do this with a custom keystroke script using a regular expression. This is a copy-n-paste example from www.pdfscripting.com -

if(!event.willCommit)
event.rc = /^\d*$/.test(event.change);

Hope this helps,

You could also just add leading zeros. [url=http://www.acrobatusers.com/forums/aucbb/viewtopic.php?id=18041]Adding "Zeros" in front of a number ...[/url]

Thanks Dimitri. It does in deed help. This is great. A few questions if I may.

I forgot to copy and past the if statement part of the code and it seems to work with or without.

Tell me if I am reading this regular expression right. Start (^) and end ($) with any number of digits (\d*).

Still trying to understand what the rc event does.

Each item number is different so users needs to be able to an item number that may or may not begin with a zero.

65823

or

06859

Thanks for the suggestion though. I can see where that could come in handy for adding other kinds of prefixes to numbers.

There are two different kinds of keystroke events. The Proper keystroke, which is called each time the user presses a key, and the WillCommit Keystroke, which is called when the user commits the field data by pressing the Return key or tabs/clicks out if the field. Each one of these events uses different event properties for different reasons. The "event.willCommit" property is used to differenciate which one is being called.

"event.rc" is used to accept or reject the particular user action. For a proper keystroke event, "event.rc=false" will reject keystrokes. For the WillCommit keystroke, "event.rc=false" will reject the entire input.

Your reading of the regular expression is correctly.

I'm coming back to this with another problem. I have a field that needs to put it's value into some other read only fields. I set up a calculation script in field "Txt.DeptID2" to get the value from the field "Txt.DeptID". Field "Txt.DeptID2" and several other instances of it are read only. The value that is in "Txt.DeptID" has a value of 0000000001 but it come out in "Txt.DeptID2" as 1. I need to keep the leading zeros.

Can I turn the value into a string in this case? I don't know how to do that or if it is even the best way.

If the value in the first field has a lot of leading zeros then it is a text field and the value is a string. The second field also need to be a text field. Just having both fields as text should solve the reformatting issue.

Both fields have no formatting or in other words the formatting is set to none. There must be something in the calculation script that not working very well.

This is what I am using for a Custom Calculation script in the read only field.

var myVal = getField("Txt.DeptID").value;
this.event.value = myVal;

Sorry, I assumed this was a LiveCycle Form:( Try this code

event.value = getField("Txt.DeptID").valueAsString;

I wish it was a LiveCycle form.

Thanks. This works great. In the mean time while I was waiting for a reply and trying things out I came up with this script that seems to work in a Custom Calculation script for the "Txt.DeptID" field. Your solution takes up a lot less space. So I think I will use it instead.

//var myVal = this.event.value;
//var myNewVal = myVal.toString();
//getField("Txt.DeptID2").value = myNewVal;

Where could I have found valueAsString? Is this a core JavaScript thing? Some times I'm not sure what to look for.

Anyway thanks heaps.

Hi StevenD,

valueAsString is in the Acrobat JavaScript Reference under "Text Field-Properties."
