如何使用 Jquery 触发 js function

Question

I want to trigger this jquery function by using trigger method of JQuery. How can I do that? Actually I dont even know the trigger method is suitable for user defined functions.

$('a.pop').click(function() {alert('testing'); }

this is not working

 $('a').trigger(testtt);

 var testtt = function(){ alert('aaa');} 

Answer 1

Very similar to the way you install the event handler:

$('a.pop').click();

If you have the name of the event you want to trigger as a string, you can also do it this way:

$('a.pop').trigger('click');

This is also the solution to use if you want to pass crafted data to the event handler -- trigger also accepts a second parameter.

Answer 2

You can trigger a click event on the element by simply running

$('a.pop').click()

Answer 3

$('a.pop').click() , or if you're triggering some dynamic method, or custom event:

$('a.pop').trigger(eventName) , eg: $('a.pop').trigger('click');

Answer 4

Reading from jQuery API, the following should work.

$('a.pop').trigger('click');

Answer 5

.trigger() is used to trigger event handlers (custom or built-in'). Since you bound your function to the "click" handler, you can use trigger like so to call it:

$('a.pop').trigger('click');

jQuery's event binding methods can also be called without parameters to trigger them, which means you can also do this:

$('a.pop').click();
