JavaScript方法和技巧大全 基礎知識
1 創建腳本塊 <script language=”JavaScript”> JavaScript code goes here </script>
2 隱藏腳本代碼 <script language=”JavaScript”><!-- document.write(“Hello”); --> </script>
在不支持JavaScript的瀏覽器中將不執行相關代碼

document.body.scrollTop = 200;} else { //如果是NetScape瀏覽器則使用pageYOffset屬性
window.pageYOffset = 200;}</script>
63 設置頁面的滾動位置 <script language=”JavaScript”> if (document.all) { //如果是IE瀏覽器則使用scrollTop屬性
document.body.scrollTop = 200;} else { //如果是NetScape瀏覽器則使用pageYOffset屬性
window.pageYOffset = 200;}</script>
64 在IE中打開全屏窗口
<a href='#' onClick=”window.open([url]http://www.phpNet.cn/[/url]','newWindow','fullScreen=yes');”>Open a full-screen window</a>
65 新窗口和父窗口的操作<script language=”JavaScript”> //定義新窗口
<a href='#' onClick=”window.open([url]http://www.phpNet.cn/[/url]','newWindow','fullScreen=yes');”>Open a full-screen window</a>
65 新窗口和父窗口的操作<script language=”JavaScript”> //定義新窗口
var
newWindow = window.open(“128a .html”,”newWindow”);
newWindow.close(); //在父窗口中關閉打開的新窗口 </script>
在新窗口中關閉父窗口 window.opener.close()
66 往新窗口中寫內容 <script language=”JavaScript”> var newWindow = window.open(“”,”newWindow”);
在新窗口中關閉父窗口 window.opener.close()
66 往新窗口中寫內容 <script language=”JavaScript”> var newWindow = window.open(“”,”newWindow”);
newWindow.document.open();
newWindow.document.write(“This is a new window”); newWIndow.document.close();</script>
67 加載頁面到框架頁面 <frameset cols=”50%,*”> <frame name=”frame1” src="/”135a .html"”>
67 加載頁面到框架頁面 <frameset cols=”50%,*”> <frame name=”frame
<frame name=”frame2”
src="/”about:blank"”></frameset>
在frame1中加載frame2中的頁面
parent.frame2.document.location = “135b.html”;
68 在框架頁面之間共享腳本 如果在frame1中html文件中有個腳本 function doAlert() {
window.alert(“Frame 1 is loaded”);}
那麼在frame2中可以如此調用該方法<body
onLoad=”parent.frame1.doAlert();”>This is frame 2.</body>
69 數據公用 可以在框架頁面定義數據項，使得該數據可以被多個框架中的頁面公用
<script language=”JavaScript”>var persistentVariable = “This is a persistent value”;</script>
<frameset cols=”50%,*”><frame name=”frame1” src="/”138a .html"”><frame name=”frame2”
src="/”138b.html"”>
</frameset>這樣在frame1和frame2中都可以使用變量persistentVariable
70 框架代碼庫 根據以上的一些思路，我們可以使用一個隱藏的框架頁面來作爲整個框架集的代碼庫
<frameset cols=”0,50%,*”> <frame name=”codeFrame” src="/”140code.html"”> <frame name=”frame1”
src="/”140a .html"”>
<frame name=”frame2”
src="/”140b.html"”></frameset>
