jquery stop child triggering parent event

Question

Do this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        e.stopPropagation();
   });
});

If you want to read more on .stopPropagation(), look here.

Or, rather than having an extra event handler to prevent another handler, you can use the Event Object argument passed to your click event handler to determine whether a child was clicked. target will be the clicked element and currentTarget will be the .header div:

$(".header").click(function(e){
     //Do nothing if .header was not directly clicked
     if(e.target !== e.currentTarget) return;

     $(this).children(".children").toggle();
});

Better way by using on() with chaining like,

$(document).ready(function(){
    $(".header").on('click',function(){
        $(this).children(".children").toggle();
    }).on('click','a',function(e) {
        e.stopPropagation();
   });
});

I stumbled upon this question, looking for another answer.

I wanted to prevent all children from triggering the parent.

JavaScript:

document.getElementById("parent").addEventListener("click", function (e) {
    if (this !== event.target) return;
    // Do something
});

jQuery:

$("#parent").click(function () {
    // Do something
}).children().on("click", function (e) {
    e.stopPropagation();
});
