How to Get All of the Ids with Jquery

How to get all of the IDs with jQuery?

//but i cannot really get the id and assign it to an array that is not with in the scope?(or can I)

Yes, you can!

var IDs = [];
$("#mydiv").find("span").each(function(){ IDs.push(this.id); });

This is the beauty of closures.

Note that while you were on the right track, sighohwell and cletus both point out more reliable and concise ways of accomplishing this, taking advantage of attribute filters (to limit matched elements to those with IDs) and jQuery's built-in map() function:

var IDs = $("#mydiv span[id]")         // find spans with ID attribute
  .map(function() { return this.id; }) // convert to set of IDs
  .get(); // convert to instance of Array (optional)

jQuery - find all IDs in a class

Use .each()

var idArray = [];
$('.red').each(function () {
    idArray.push(this.id);
});

Jquery, getting back list of ID strings of all elements with ID's that begin with a string?

Live Demo

var elements = [];

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

var stringOfElementIDs = elements.toString();

Get id's of all child elements with a particular class

Use map().

Also, correct your HTML markup like in the snippet(class="").

Finally, use .get() if you need a true JavaScript array (instead of a jQuery collection of strings — jQuery's collections [sets] usually contain DOM elements, but can contain anything).

var ids = $('#ulList .vehicle').map(function(){  return $(this).attr('id');  }).get();
console.log(ids);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><ul id="ulList">  <li id="car" class="vehicle"></li>  <li id="bus" class="vehicle"></li>  <li id="cat" class="animal"></li>  <li id="dog" class="animal"></li>  <li id="bike" class="vehicle"></li>  <li id="monkey" class="animal"></li></ul>
