text 加载ajax popup django html javascript

Posted 2021-05-01

1. Add this div in your main template (if you are extending) at the bottom of your body element

<div class="modal"><!-- Place at bottom of page --></div>

2. Add this to your css file

* Start by setting display:none to make this hidden.
   Then we position it in relation to the viewport window
   with position:fixed. Width, height, top and left speak
   for themselves. Background we set to 80% white with
   our animation centered, and no-repeating */
.modal {
    display:    none;
    position:   fixed;
    z-index:    1000;
    top:        0;
    left:       0;
    height:     100%;
    width:      100%;
    background: rgba( 255, 255, 255, .8 ) 
                url('http://i.stack.imgur.com/FhHRx.gif') 
                50% 50% 
                no-repeat;
}

/* When the body has the loading class, we turn
   the scrollbar off with overflow:hidden */
body.loading .modal {
    overflow: hidden;   
}

/* Anytime the body has the loading class, our
   modal element will be visible */
body.loading .modal {
    display: block;
}

3. Add this jquery code

Enjoy! 

        $body = $("body");

        $(document).ajaxStart(
            function() {
                alert("starting")
                $body.addClass("loading");

            }
        );
        $(document).ajaxStop(
            function() {
                alert("Stopping")
                $body.removeClass("loading");
            }
        );
