Calling a function on bootstrap modal open

问题:

I used to use JQuery UI's dialog, and it had the open option, where you can specify some Javascript code to execute once the dialog is opened. I would have used that option to select the text within the dialog using a function I have.

Now I want to do that using bootstrap's modal. Below is the HTMl code:

<div id="code" class="modal hide fade">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h3>Modal header</h3>
    </div>
    <div class="modal-body">
        <pre>
print 'Hello World'

And as for the button that opens the modal:

 <a href="#code" data-toggle="modal" class="btn code-dialog">Display code</a>

I tried to use an onclick listener of the button, but the alert message was displayed before the modal appeared:

$( ".code-dialog" ).click(function(){
    alert("I want this to appear after the modal has opened!");
});

回答1:

You can use the shown event/show event based on what you need:

$( "#code" ).on('shown', function(){
    alert("I want this to appear after the modal has opened!");
});

Update for Bootstrap 3.0

For Bootstrap 3.0 you can still use the shown event but you would use it like this:

$('#code').on('shown.bs.modal', function (e) {
  // do something...
})

See the Bootstrap 3.0 docs here under "Events".

回答2:

will not work.. use $(window) instead

//FOR SHOWING

$(window).on('shown.bs.modal', function() { 
    $('#code').modal('show');
    alert('shown');
});

//FOR HIDDING

$(window).on('hidden.bs.modal', function() { 
    $('#code').modal('hide');
    alert('hidden');
});

回答3:

you can use show instead of shown for making the function to load just before modal open, instead of after modal open.

$('#code').on('show.bs.modal', function (e) {
  // do something...
})

回答4:

Bootstrap modal exposes events. Listen for the the shown event like this

$('#my-modal').on('shown', function(){
  // code here
});

回答5:

if somebody still has a problem the only thing working perfectly for me by useing (loaded.bs.modal) :

 $('#editModal').on('loaded.bs.modal', function () {
       console.log('edit modal loaded');

       $('.datepicker').datepicker({
            dateFormat: 'yy-mm-dd',
            clearBtn: true,
            rtl: false,
            todayHighlight: true,
            toggleActive: true,
            changeYear: true,
            changeMonth: true
        });
});

回答6:

You can use belw code for show and hide bootstrap model.

$('#my-model').on('shown.bs.modal', function (e) {
  // do something here...
})

and if you want to hide model then you can use below code.

$('#my-model').on('hidden.bs.modal', function() {
    // do something here...
});

I hope this answer is useful for your project.
