Question

I have a jquery function (‘rater’) that I call this way:

<div id="someID"></div>

<script type="text/javascript">
    $('#someID').rater({options});
</script>

I want to get the ID (‘someID’ in this case) so then I can use it inside the function as a variable.

Then I use it in something like this:

if (??? == 'someID') { do something }

How can I do it??

Answer 1

Retrieving the selector used to call the plugin:

jQuery.fn.myPlugin = function() {
    alert( this.selector );
};

You can access the selector as a property of the jQuery object.

So, if I called the plugin like this:

$('div #something').myPlugin();

Then “div #something” would be alerted.

Retrieving an element’s ID from within a plugin:

jQuery.fn.myPlugin = function() {
    alert( this.attr('id') );
};
