我们可以为弹出框内的按钮编写脚本吗？

Question

I have created a popover so that if I click on the image the popover should appear.

The popover is working. what my main problem is I have inserted buttons in the popover.

so I want to write javascript or jquery code for the button when it is clicked. Can anyone help on this?

I have tried but it's not working!!!!

 $(function() { $('button').click(function() { var x = $(this).attr('class'); alert(x); }); }); $(function() { $("[data-toggle=popover]").popover({ html: true, container: 'body', content: function() { var content = $(this).attr("data-popover-content"); return $(content).children(".popover-body").html(); }, title: function() { var title = $(this).attr("data-popover-content"); return $(title).children(".popover-heading").html(); }, placement: "auto" }); });

Answer 1

Ok Here is an updated version of my answer and checked and working code. A secret of a popover is to fire the correspondence function in a right time with a popover firing. So the JS code is:

function firePopover() {
            $('.hidden').css('display', 'block');
            var delay = 100;
            setTimeout(function () {
                $('button:not(.main)').unbind('click');
                $('button:not(.main)').click(function () {
                    var x = $(this).attr('class');
                    alert(x);
                    $('.hidden').css('display', 'none');
                });
            }, delay);
        }

Here I an using html selector

:not(.main)

to prevent binding and unbinding events to the main button. In addition, we have to pay attention on the fact that every popover rising binds a new event handler to each button. This means that after n popover risings every button will fire it's alert n times. To prevent this effect, it is possible to bind events in the first rising only, or as I did, to unbind an event from a button every popover rising. As to html code, here it is:

<button class="main" onclick="firePopover()">Fire Popover</button>
<div id="moreoptions" class="hidden" hidden>
    <div class="popover-body">
        <div class="list-group">
            <button class="class-0 list-group-item"><span class="gap"></span>Edit</button>
            <button class="class-1 list-group-item"><span class="gap"></span>Logic Builder</button>
            <button class="class-2 list-group-item"><span class="gap"></span>Uneploy</button>
        </div>
    </div>
</div>

I only added the ".main" button to accept a simulation, and each button got additional corresponding class "class-0", "class-1", "class-2" for successful demonstration. Now, when you push on the main button, other 3 buttons appear. And to the contrary, pushing on any of those 3 buttons, is following by alert firing and disappearing of all of them. I hope this will help you.

  function firePopover() { $('.hidden').css('display', 'block'); var delay = 100; setTimeout(function () { $('button:not(.main)').unbind('click'); $('button:not(.main)').click(function () { var x = $(this).attr('class'); alert(x); $('.hidden').css('display', 'none'); }); }, delay); } 

 .hidden { display: none; } button { float: left; } .class-0 { clear: left; }
