jQuery onclick事件调用函数

Question

I have the following code:

 function hvcm_wait() { waitingDialog.show('Please wait while your VM is rebooting...'); } $('#hv_ConfirmShutDown').on('show.bs.modal', function(e) { $(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href')); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <a class="btn btn-danger btn-ok">Shutdown Now</a> 

How do I call the javascript function hvcm_wait() when .btn-ok is clicked is clicked in Modal?

Any help would be highly apperciated. Thanks!

Answer 1

Assuming that .btn-ok is not present when script is loaded, so use event-delegation.

Add these lines after hvcm_wait() function

$('#hv_ConfirmShutDown').on('click', '.btn-ok', function() {
    hvcm_wait();
})

Or if it is present in DOM then you can directly do this

$('.btn-ok').click(function() {
    hvcm_wait();
})

Answer 2

或者您可以将其直接添加到HTML中，如下所示：

<a class="btn btn-danger btn-ok" onclick="hvcm_wait()">Shutdown Now</a>

Answer 3

I would use this, first in the $() you search for the class btn-ok, then you hand it a onClick handler that executes the function.

$(".btn-ok").click(function(){
    hvcm_wait();
});

Answer 4

You are adding href attribute here. First you need to prevent the href and call the normal function.

 $(".btn-ok").click(function(event){
     event.preventDefault();
     hvcm_wait(); 
 });
