Get Name of checkbox field from click

[Richard233923575d4b]

Hello All, 

First time post here, but I couldn't find anything on this particular subject so I felt I needed to reach out.

I have a document with hundreds of checkboxes. I'm trying to instruct these checkboxes to run a document level code on mouseup, but in order for it to run correctly, I need the name of the checkbox field being checked/unchecked. I am currently doing this by looping through all fields in the document, but it's causing the document to be really slow. 

I've tried using event.source.name and other variants, but no luck. 

Any help would be appreciated.

It's event.target.name, actually.

It's event.target.name, actually.

// name of active field
var strFldName = event.target.name;

// if field's name contain "text-12"
if (/text-12/.test(strFldName)) {
// your script here
}

Thanks very much, JR. 

It wouldn't work until I added an additional line passing the "event.target.name" to a variable.

// I was trying this...
functionName(event.target.name);

// This is what worked

var myName = event.target.name
functionName(myName);

This is a bit dangerous to use, because if you use this method to look for "text-1", for example, it will match both "text-1", as well as "text-10", "text-11", "text-115", etc.

try67 is right, you should use this instead, "\b" means "word limit":

if (/\btext-12\b/.test(strFldName)) {

Not sure why you need a regular expression at all... You can just do a simple comparison, like this:

if (event.target.name=="text-12") {

Many thanks to you both for your feedback on this. 

I took the time to rename all of the checkboxes before starting this, but I appreciate you two bringing this point up. 

This is really a simple bit of code to highlight a premade selection of text when the corresponding checkbox is selected (to make selections more easily visible). In case anyone else comes up on a similar problem, I'll include my code below.

// code in each checkbox

var myName = event.target.name;
var myPage = this.pageNum;
hiLighter(myName, myPage);

//document level javascript function

function hiLighter(myName, myPage)
{
var curField = this.getField(myName);
if (curField.type == "checkbox") {
    var hiLite = this.getAnnot(myPage, "HL."+myName);
    if (hiLite != null){
    if (curField.value == "Yes") hiLite.hidden = false;
    if (curField.value == "Off") hiLite.hidden = true;
}
}
}
