Twitter bootstrap stop propagation on dropdown open

问题

I have a twitter bootstrap dropdown inside a div with the plugin jOrgChart.

The problem I'm having is that when I click the button to open the dropdown menu it also triggers a click event in the parent div that does a collapse of other elements.

This is my html:

<div id="chart">
<div class="node">
    <div class="btn-group">
        <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
        Actions
        <span class="caret"></span>
        </a>
        <ul class="dropdown-menu" style="text-align:left;">
            <li><a href="#">Edit</a></li>
            <li><a href="#">Delete</a></li>
        </ul>
    </div>
</div>

<div class="node">
...
</div>

I want to prevent the click of a.dropdown-toggle from bubbling to div.node, I tried with this:

$("div#chart div.btn-group > a.dropdown-toggle").click(function (e) {
            e.stopPropagation();
        });

But now the dropdown isn't working.

EDIT

This is the concrete case: http://jsfiddle.net/UTYma/2/ (Thanks to Joe Tuskan for starting the fiddle)

回答1:

$("#orgchart").jOrgChart({ chartElement: '#chart' });

$("div#chart div.btn-group > a.dropdown-toggle, .dropdown-menu li a").click(function(e) {
    e.stopPropagation();
    $('.dropdown-menu').toggle();
});

Stop Propagation then toggle. Example

I had to add the drop down menu items to the click handler to keep the behavior constant.

Try something like this:

$("div#chart div.btn-group > a.dropdown-toggle").click(function (e) {

            e.isDropDownToggleEvent =true;
})

Then:

$("div.node").click(function (e) {
     if (e.isDropDownToggleEvent != null && e.isDropDownToggleEvent)
         return false;

     return true;      
})

You can also try to put e.preventDefault() or e.stopPropagation(); instead of return false.

回答3:

I used

$('.multiselect').on('click', function (e) {
    $(this).next('.dropdown-menu').toggle();
    e.stopPropagation();
});

This is similar to @Joe's answer, but a bit more generic

回答4:

$("div#chart div.btn-group > a.dropdown-toggle, .dropdown-menu li a").click(function(e) {
    e.stopPropagation();
    $(this).closest('.dropdown').toggleClass('open');
});

You should use this instead as above solution doesn't close the dropdown on focus out.

回答5:

If I understand correctly, you want to avoid closing menu.

$("div#chart .dropdown-menu li").bind('click',function (e) {
            e.stopPropagation();
        },false);

回答6:

Building on Joe's answer, this includes the normal dropdown functionality of closing on the next click.

$("#orgchart").jOrgChart({ chartElement: '#chart' });

$("div#chart div.btn-group > a.dropdown-toggle, .dropdown-menu li a").click((e) => {
    e.stopPropagation();
    $('.dropdown-menu').toggle();

    // close on next click only
    $(window).one("click", () => $('.dropdown-menu').toggle());
});
