jQuery .on() click event catching dynamic 'data-' attribute in list of buttons to pass value to other function?

Question

I have a dynamic table list of around 40 rows each with an edit button containing a date field. I also have the following click event script trying to attach to each button via a common class which needs to access the value of a data- attribute within the button image code seen further below:

$('.showEdt').each(function () {    var $this = $(this);    $(this).on("click",$this.data('eValz'), function () {           alert(this);    });  }); 

Example of the edit buttons which are dynamically generated:

<img src="edit.png" title="edit" class="showEdt" data-evalz="(eyCKeVua/TNF117)" /> 

Problem:

The script loads ok, when the edit button is clicked the alert displays: [object HTMLImageElement] instead of the data-evalz value ??

Please provide suggestions of how I can access the data unique to the button that is clicked?

Answer 1

You're not using the on function correctly. Here's one way you can do this: FIDDLE

$('.showEdt').each(function () {     var $this = $(this);     $this.on("click", function () {         alert($(this).data('evalz'));     }); }); 

Also, notice you've written eValz instead of evalz on your code. Data attributes are case-sensitive so be careful with how you write them.
