JQuery iterate through string occurrences

I've an HTML like this

blalblala < span id="myID" >bla < /s开发者_开发百科pan> blalba < span id="myID > bla< /span> and so on...

Now I would to get the left position of all items of kind myID. I've tried with this code

var x = "";   
$('.myID').each(function(index) { 
    x += " " + $(this).position().left+",";  
}); 
return x;

But it's wrong because it does not return anything. What's wrong? Thanks

You should not use id on more than one element. The appropriate attribute to use is class.

<span class="myClass" >bla < /span> 
<span class="myClass"> bla< /span>

And then your code should work if you update the selector to be:

$('.myClass')

var x = new Array;
$('.myID').each(function(index) { x[index] = $(this).position().left; });
console.log(x);

try that and see what is present in the array x.

• you have multiple identical IDs in your document [fragment]
• you are using the class selector, while you have IDs
