asp.net給頁面增加一個層

在做登錄的時候想著別老是用跳轉(zhuǎn)頁面，用戶體驗超差的，而且對于網(wǎng)速慢的用訪來說，還要去跳轉(zhuǎn)一次重新加載一個新的頁面，顯得有點不爽!就弄了一個層直接在當(dāng)前頁面跳轉(zhuǎn)!

廢話不說直接上代碼!

function ShowNo() //隱藏兩個層

{

document.getElementById("doing").style.display = "none";

document.getElementById("divLogin").style.display = "none";

}

function $(id) {

return (document.getElementById) ? document.getElementById(id) : document.all[id];

}

function showFloat() //根據(jù)屏幕的大小顯示兩個層

{

var range = getRange();

$('doing').style.width = range.width + "px";

$('doing').style.height = range.height + "px";

$('doing').style.display = "block";

document.getElementById("divLogin").style.display = "";

}

function getRange() //得到屏幕的大小

{

var top = document.body.scrollTop;

var left = document.body.scrollLeft;

var height = document.body.clientHeight;

var width = document.body.clientWidth;

if (top == 0 && left == 0 && height == 0 && width == 0) {

top = document.documentElement.scrollTop;

left = document.documentElement.scrollLeft;

height = document.documentElement.clientHeight;

width = document.documentElement.clientWidth;

}

return { top: top, left: left, height: height, width: width };

}
