还可以把上篇文章的弹出层居中效果的制作和本例一起加个

主要代码:
复制代码代码如下:
var Class = {
min_w:960,
bint: function(r) {
$(r).style.display = "block";
$(r).style.height =Math.max(parseInt(document.documentElement.scrollHeight),parseInt(document.documentElement.offsetHeight))+ "px";
$(r).style.width = Math.max(parseInt(document.body.offsetWidth),Class.min_w)+"px";
},
x: function(r,d) {
for (i = 1; i < r; i++) {
var c = document.createElement("div");
c.innerHTML = i;
$(d).appendChild(c);
}
},
res: function(r,wr) {
$(r).style.width = Math.max(parseInt(document.body.offsetWidth),Class.min_w)+"px";
$(r).style.height =Math.max(parseInt(document.documentElement.scrollHeight),parseInt(document.documentElement.offsetHeight))+ "px";
}
};
