jQuery trigger click vs click ()?

Question

I have this simple code : here

$(\".btn\").on(\'click\',function () {

  $(\".a\").trigger(\'click\');
});

$(\".btn2\").on(\'click\',funct         


        

Answer 1

Actually $(".a").trigger('click'); triggers the click event but it doesn't mean that it'll click the link, instead it'll execute the event handler if you already have one, i.e.

$(".btn, .btn2").on('click',function () {
    $($(".a")[0]).trigger('click'); // first element
});

$(".a").on('click', function (e){
    alert(e.target);
});​

The given example will trigger the click event of the a and will execute the handler (the anonymous function) that's already have been registered for that event using

$(".a").on('click', function (e){...});
