1、 彈出提示框
Alert("提示框，呵呵");
2、 彈出確認框
return confirm("確認框，呵呵");
四、其它常用JS
1. oncontextmenu="window.event.returnValue=false" 將徹底屏蔽滑鼠右鍵
<table border oncontextmenu=return(false)><td>no</table> 可用於Table
2. <body onselectstart="return false"> 取消選取、防止複製
3. onpaste="return false" 不準粘貼
4. oncopy="return false;" oncut="return false;" 防止複製
5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址欄前換成自己的表徵圖
6. 可以在收藏夾中顯示出你的表徵圖
7. 關閉IME
8. 永遠都會帶著架構 <script language="JavaScript"><!-- if (window == top)top.location.href = "frames.htm"; //frames.htm為框架頁 // --></script>
9. 防止被人frame <SCRIPT LANGUAGE=JAVASCRIPT><!-- if (top.location != self.location)top.location=self.location; // --></SCRIPT>
10. 網頁將不能被另存新檔
11. <input type=button value=查看網頁原始碼 onclick="window.location = \'view-source:\'+ \'http://www.csdn.net/\'">
12. 怎樣通過asp的手段來檢查來訪者是否用了代理
<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" then
response.write "<font color=#FF0000>您通過了Proxy 伺服器，"& _ "真實的IP為"&Request.ServerVariables("HTTP_X_FORWARDED_FOR") end if %>
13. 取得控制項的絕對位置
//Javascript
<script language="Javascript">
function getIE(e)
{ var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent)
{ t+=e.offsetTop;
l+=e.offsetLeft;
}
alert("top="+t+"\nleft="+l);
}
</script>
//VBScript
<script language="VBScript">
<!-- function getIE()
dim t,l,a,b
set a=document.all.img1
t=document.all.img1.offsetTop
l=document.all.img1.offsetLeft
while a.tagName<>"BODY"
set
a = a.offsetParent
t=t+a.offsetTop
l=l+a.offsetLeft
wend
msgbox "top="&t&chr(13)&"left="&l,64,"得到控制項的位置"
end function -->
</script>
14. 游標是停在文字框文字的最後
<script language="javascript">
function cc()
{ var e = event.srcElement;
var r =e.createTextRange();
r.moveStart(\'character\',e.value.length);
r.collapse(true);
r.select(); }
</script> <input type=text name=text1 value="123" onfocus="cc()">
15. 判斷上一頁的來源
asp: request.servervariables("HTTP_REFERER")
java script: document.referrer
16. 最小化、最大化、關閉視窗
<object id=hh1
classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Minimize">
</object>
<object
id=hh2 classid="clsid:ADB880A6-D8FF-11CF-9377-00AA003B7A11">
<param name="Command" value="Maximize"></object>
<OBJECT id=hh3
classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM NAME="Command" VALUE="Close"></OBJECT>
<input type=button value=最小化 onclick=hh1.Click()>
<input type=button value=最大化 onclick=hh2.Click()><input type=button value=關閉 onclick=hh3.Click()> 本例適用於IE
