test if event handler is bound to an element in jQuery

Tried to do the following (link is jQuery object of 'a' tag):

 link.data("events") //undefined even if link has event handlers

 jQuery.data(link, 'events') //undefined always also

 jQuery._data(link, 'events') //undefined always also

using jquery-1.8.3

So, how to check if element has click handler?

You can use jQuery._data to check for events. The first argument should be a reference to the HTML element, not the jQuery object.

var ev = $._data(element, 'events');

if(ev && ev.click) alert('click bound');

Sample below.

$(function(){

    $('#test').click(function(){

        // NOTE: this below is refering to the HTML element, NOT the jQuery element

        var ev = $._data(this, 'events');

        if(ev && ev.click) alert('click bound to this button');

    });

});

<script src=https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js></script>

<button id=test>Click me to check for click handlers</button>

Also note that this method for checking events will only work when the event is bound via jQuery. If the event is bound via element.attachEventListener, element.onclick, <a onclick=doStuff()> or any other non jQuery way, this will not work. If you're fitting into this boat, check this answer.
