40種網頁常用小技巧(javascript)
1. oncontextmenu="window.event.returnValue=false" 將徹底屏蔽鼠標右鍵
<table border oncontextmenu=return(false)><td>no</table> 可用于Table
2. <body onselectstart="return false"> 取消選取、防止復制
3. onpaste="return false" 不準粘貼
4. oncopy="return false;" oncut="return false;" 防止復制
5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址欄前換成自己的圖標
6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夾中顯示出你的圖標
7. <input style="ime-mode:disabled"> 關閉輸入法
8. 永遠都會帶著框架
<script language="javascript"><!--
if (window == top)top.location.href = "frames.htm"; //frames.htm為框架網頁
// --></script>
9. 防止被人frame
<SCRIPT LANGUAGE=javascript><!--
if (top.location != self.location)top.location=self.location;
// --></SCRIPT>
10. 網頁將不能被另存為
<noscript><iframe src=*.html></iframe></noscript>
11. <input type=button value=查看網頁源代碼
onclick="window.location = "view-source:"+ "http://www.gonet8.com"">
12.刪除時確認
<a href="javascript:if(confirm("確實要刪除嗎?"))location="boos.asp?&areyou=刪除&page=1"">刪除</a>
13. 取得控件的絕對位置
//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,"得到控件的位置"
end function
--></script>
14. 光標是停在文本框文字的最后
<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
javascript:
document.referrer
16. 最小化、最大化、關閉窗口
<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()>
本例適用于IE
17.屏蔽功能鍵Shift,Alt,Ctrl
<script>
function look(){
