用这锻代码 之前请先下载jquery库
var maskStackCount = 0;
function mask(method){
//这里是你想要进行遮罩的窗口,我这里想要遮罩的是一个iframe窗口,也可以用var winObj=$(window)
var winObj=window.top.$("body").find("iframe[name='dialognormaliframe']");
if(typeof method == "undefined"){
method="open";
}
if (method == "open") {
if (maskStackCount var mask = $("").appendTo("body");
mask.css({
width: winObj.width() + "px",
height: winObj.height() + "px",
filter: "alpha(opacity=60)"
}).show();
winObj.on("resize.mask", function(){
mask.css({
width: winObj.width() + "px",
height: winObj.height() + "px"
});
});
}
maskStackCount++;
}
else if(method == "close"){
maskStackCount--;
$("#window-mask").remove();
winObj.off("resize.mask");
}
}
复制代码 代码如下:
var maskStackCount = 0;
function mask(method){
//这里是你想要进行遮罩的窗口,我这里想要遮罩的是一个iframe窗口,也可以用var winObj=$(window)
var winObj=window.top.$("body").find("iframe[name='dialognormaliframe']");
if(typeof method == "undefined"){
method="open";
}
if (method == "open") {
if (maskStackCount var mask = $("").appendTo("body");
mask.css({
width: winObj.width() + "px",
height: winObj.height() + "px",
filter: "alpha(opacity=60)"
}).show();
winObj.on("resize.mask", function(){
mask.css({
width: winObj.width() + "px",
height: winObj.height() + "px"
});
});
}
maskStackCount++;
}
else if(method == "close"){
maskStackCount--;
$("#window-mask").remove();
winObj.off("resize.mask");
}
}
