用這鍛代碼之前請先下載jquery庫

複製代碼 代碼如下:

var maskStackCount = 0;

function mask(method){

//這裡是你想要進行遮罩的窗口，我這裡想要遮罩的是一個iframe窗口，也可以用var winObj=$(window)

var winObj=window.top.$("body").find("iframe[name='dialognormaliframe']");

        if(typeof method == "undefined"){
            ") {
            if (maskStackCount                 var mask = $("

")body." >                mask.css({
                    width:     winObj.width() "px",
                    height:     winObj.height() "px",
                    filter: "alpha(opacity=60)"
}).show();
                    winObj.on("resize.mask", function( {
                        width:           height }:     winObj.height() "px"
                            }
            maskStackCount ;
        }
   >            maskStackCount--;
            $("#window-mask").remove( mask");
        }
}
