Question

I’m not a Javascript guru as I do more server-side work so am struggling with this. I have found bits and pieces of how to do this. Basically, I have a series of elements that have ids beginning with the string “tagRow_” and I need to get back a list of all of the actual element ids as I need not just the element but also the element’s id as I need to parse the unique ending for each on the server-side to determine what it corresponds to.

I found the code below to get all elements but am not sure what it is returning as far as a list or what, if anyone can offer advice how to return just a list of string id names I would appreciate it. Thanks

EDIT: I actually need to do this with a radio input field, it was by mistake I put a DIV in my own example. It works fine for a DIV but is not working properly for a radio input like below:

 <input id="tagRow_ddd" type="radio" value="h">
                <input id="tagRow_ddd" type="radio" value="p">
                    <input id="tagRow_ddd" type="radio" value="r">
                    <input id="tagRow_ddd" type="radio" value="c">

$("input[id^='tagRow_']").each(function() {

   var id = this.id,
       idNumber = id.replace(/\D+/, '');
   document.body.innerHTML += idNumber + '<br />';
});

var elements = [];

$("div[id^='tagRow_']").each(function(){
   elements.push(this.id); 
});

var stringOfElementIDs = elements.toString();
