JS代码
(function($) {
$("#progressImgage").hide();
$("#maskOfProgressImage").hide();
//备份jquery的ajax方法
var _ajax = $.ajax;
//重写jquery的ajax方法
$.ajax = function(options) {
var img = $("#progressImgage");
var mask = $("#maskOfProgressImage");
img.removeClass(‘hide‘);
mask.removeClass(‘hide‘);
var complete = options.complete;
options.complete = function(httpRequest, status) {
img.hide();
mask.hide();
if (complete) {
complete(httpRequest, status);
}
};
img.show();
img.show().css({
"position" : "fixed",
"top" : "50%",
"left" : "50%",
"width" : "150px",
"height" : "150px",
"margin-top" : function() {
return -1 * img.height() / 2;
},
"margin-left" : function() {
return -1 * img.width() / 2;
}
});
mask.show().css("opacity", "0.2" );
return _ajax(options);
}
})(jQuery);
CSS代码:
.error {
color: red;
margin: 15px;
}
.hide {
display: none;
}
.progress {
z-index: 2000
}
.mask {
position: fixed;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 1000;
background-color: #000000
}
html代码:
<img id="progressImgage" class="progress hide" src="<c:url value="/resources/img/ajax-loader.gif"/>" />
<div id="maskOfProgressImage" class="mask hide"></div>
下面是我使用的gif:
效果如下:
