Question

I’m having an issue with the .each() function in jQuery, I’m calling these lines when I successfully getAjax and store it in the data variable:

$.each(data, function() {
$('#modulesList').append("<p><a href='#'>" + this.code + "</a></p>")
  .click(function(){
    alert($(this));
   });
});

The problem is, Once I click on one of my a elements(Which all look fine and have the correct text) I get the alert popping up 5 times for each of them. Iterating from the 0 to 5 objects in the JSON.

Anybody know why?

Thanks!

Answer 1

Use the appendTo method

$("<p><a href='#'>" + this.code + "</a></p>").appendTo('#modulesList')
  .click(function(){
    alert($(this));
   })

jQuery ~ always returns the main element: now you selector is a dom element and this gets created and returned as a jQuery Object.

And to answer you question of why you get 5 alerts . Before you bound the click event to #modulesList one for each object in the data array. (Thats why the 5 alerts)

You can also store your <p><a>... in a variable like so:

var pAndATag = $("<p><a href='#'>" + this.code + "</a></p>");
$(modulesList).append(pAndATag);

hope you see how this works…
