how to prevent the click event of the parent when its children is being dragged

问题

Here is a sample code:

$('.bmc-div').click(function(e){
    e.stopPropagation();
    // console.log(e.target);
    if ($(e.target).hasClass('my-sticky')) {

    } else {
        canvas.add_sticky($(this));
    }
});

$('.bmc-div .sticky_container').sortable({
    cursor: 'move',
    revert: true,  
    helper: 'clone',
    // handle: ".element-handler",
    connectWith: '.bmc-div .sticky_container',
    scroll: true,
    cancel: null,
    opacity: 0.7,
    // axis: 'y',
    items: ".my-sticky",
    placeholder : "sticky-placeholder",
    containment: "#main",
    zIndex: 9999,
    start: function(event, ui) {
        event.stopPropagation();
    },
    stop: function(event, ui) {
        event.stopPropagation();
    },
    update: function(event, ui) {
        // update_sortable_position();
    }
}).disableSelection();

Here is the HTML Code for the question:

 <div id="bmc-rs" class="col-sm-12 bmc-div">
        <div class='bmc-row'>
             <p style='margin: 0px;'><span class="grid-label">Revenue Streams              </span><span class="pull-right"><i class="fa fa-briefcase"></i></span></p>
              </div>
              <div class="sticky_container">
                <div class="my-sticky" style="display: block;">Sample Sticky</div>
              </div>
            </div>

The problem is that the child element will be dragged but when stopped, it will still trigger the click event of the parent container.

You need to stop propagation on your draggable element's mousedown event:

$('.sticky_container').mousedown(function (event) {
    event.stopPropagation();
});
