Question

I have a tooltip on an anchor element, that sends an AJAX request on click. This element has a tooltip (from Twitter Bootstrap). I want the tooltip content to change when the AJAX request returns successfully. How can I manipulate the tooltip after initiation?

Answer 1

Just found this today whilst reading the source code. So $.tooltip(string) calls any function within the Tooltip class. And if you look at Tooltip.fixTitle, it fetches the data-original-title attribute and replaces the title value with it.

So we simply do:

$(element).tooltip('hide')
          .attr('data-original-title', newValue)
          .tooltip('fixTitle')
          .tooltip('show');

and sure enough, it updates the title, which is the value inside the tooltip.

A shorter way:

$(element).attr('title', 'NEW_TITLE')
          .tooltip('fixTitle')
          .tooltip('show');
