Debounce function in jQuery

Gunther picture Gunther · Jan 5, 2015 · Viewed 63.2k times · Source

I'm attempting to debounce a button's input using the jquery debouncing library by Ben Alman. http://benalman.com/code/projects/jquery-throttle-debounce/examples/debounce/

Currently this is the code that I have.

function foo() {
    console.log("It works!")
};

$(".my-btn").click(function() {
    $.debounce(250, foo);
});

The problem is that when I click the button, the function never executes. I'm not sure if I've misunderstood something but as far as I can tell, my code matches the example.

I ran into the same issue. The problem is happening because the debounce function returns a new function which isn't being called anywhere.

To fix this, you will have to pass in the debouncing function as a parameter to the jquery click event. Here is the code that you should have.

$(".my-btn").click($.debounce(250, function(e) {
    console.log("It works!");
}));
