JQuery API:

http://www.w3school.com.cn/jquery/jquery_ref_events.asp

See below scripts:

mask the whole browser screen

function showDiv(div_id) { if(!$("#"+div_id)[0]){    $("<div id='"+div_id+"' style='display: none;'><img src='images/loading.gif' alt='正在加载.....' /></div>").appendTo("body");    }    var div_obj = $("#"+div_id);    var windowWidth = document.body.clientWidth;    var windowHeight = document.body.clientHeight;    var popupHeight = div_obj.height();    var popupWidth = div_obj.width();    if(!$("#mask")[0]){    $("<div id='mask' style='display: none; left: 0; top: 0'></div>").appendTo("body");    }    //添加并显示遮罩层 $("#mask").css({"z-index":"99999","opacity":"0.6","display":"block","position": "absolute","background-color":"#fff"})    .width(windowWidth)    .height(windowHeight);   // .click(function() {hideDiv(div_id); })   //.fadeIn(100); div_obj.css({"z-index":"100000","position": "absolute","left":mouseleft,"top":mousetop,"display":"block"});   //.animate({left: mouseleft, top: mousetop, opacity: "show" }, "fast");}function hideDiv(div_id) {    $("#mask").css({"display":"none"});    $("#" + div_id).css({"display":"none"});//.animate({left: 0, top: 0, opacity: "hide" }, "slow");}

mask layer 先显示并设置60%透明度

"z-index":"99999" "opacity":"0.6"

loading gif 后显示，透明度100%

"z-index":"100000" opacity: "show"

gif z轴(设置最前) 必须大于mask
