Attribute value as variable name

Question

I'm trying to get a dynamic attribute value to be used as a var name What I have:

$(this).html(""+$(this).attr("id")+"");

It gives me the value as plain text. What I want is that it uses the attr("id") value as a Var like:

$(this).html(""+myVar+"")

Final example:

<div class="text" id="text1"></div>
<div class="text" id="text2"></div>


var text1 = "hello world"
var text2 = "bye world"
$(document).ready(function () {
   $(".text").click(function(){
      $(this).html(""+$(this).attr("id")+"");  
   });
});

Basically I want a dynamic way of calling to certain id's and getting their attribute value to be used as the Var name instead of plain text.

It all depends on variable namespace and scope, but generally next code should do the job.

$(".text").click(function(){
    var varFromAttr = window[$(this).attr("id")];
    $(this).html(varFromAttr);
});

Question is almost the same as this question.

I didn't know about this window[]; function. And i couldn't make out what was going on in the other questions. – Ian Hogers Nov 08 '15 at 11:31
