I have an href with data-toggle="dropdown", which I'm trying to remove. This snippet doesn't seem to work:

$(document).on('click','a',function() {
$(this).data('toggle','Phillip Senn');
});

Instead, Firebug is showing that data-toggle still equals "dropdown" and there is a new "toggle" attribut equal to "Phillip Senn".

What I'd like to do is remove it altogether.

• If you showed us your HTML, we might know that you had a data-toggle attribute on the HTML element that also has to be addressed. Come on people, if you don't show us your HTML, you WONT necessarily get a plete or best answer - always. – jfriend00 Commented Apr 6, 2012 at 0:50
• What do you mean by remove it from HTML? Are you actually trying to remove the attribute from the a element? Or the property from the dataset of the element? Or do you want to clear it from jQuery's .data() store? These are all different. – user1106925 Commented Apr 6, 2012 at 0:51
• Ah. I found a solution. I can use the removeAttr('data-toggle') to remove it. – Phillip Senn Commented Apr 6, 2012 at 0:55
• Yeah, I thought they were the same. – Phillip Senn Commented Apr 6, 2012 at 0:55

If you've got an attribute on the HTML and you want to remove both it and the jQuery data, then you would use this:

this.removeAttribute("data-toggle");
$(this).removeData('toggle');

Only, the jQuery data is updated with subsequent writes to .data(), but if you want to remove the attribute that was originally on the HTML object, then you have to call removeAttribute() too.

removeData

I do not understand how people can spend time posting a question when googling jquery remove data and clicking the first result would give them the answer in only a fraction of the time...

I think it goes something like this...

$(this).removeData('toggle');

To remove an attribute:

$(this).removeAttr("the-name-of-the-attribute");
