实用javascript技巧!
* 实现页面最大化
self.moveTo(0,0);
self.resizeTo(screen.availWidth,screen.availHeight);
self.focus();
* 默认img图片<img alt=""" " onerror=""error.jpg" " src=""mengzhaobin.jpg"" />如果没有mengzhaobin.jpg则显示error.jpg
* 屏蔽鼠标右键
oncontextmenu="window.event.returnvalue=false"
* 取消选取防止复制
<body onselectstart="return false">
* 不准粘贴
onpaste="return false"
* 防止复制
oncopy="return false;" oncut="return false;"
* 地址栏和收藏夹前有图标
<link rel="Shortcut Icon" href="favicon.ico">
<link rel="Bookmark" href="favicon.ico">
* 关闭输入法
<input style="ime-mode:-Disabled">
* 防止被人frame
if (top.location != self.location)top.location=self.location;
* 网页不能另存为
<noscript>
<iframe src="*.html">
<iframe>
<noscript>
* 查看页面源代码
<input type=button value="查看网页源代码 " onClick="window.location = `view-source:`+ http://www.xxx.xxx/`";>
* 弹出对话框并跳转 <a href=`javascript:if(confirm("delete?"location="http://www.xxx.xxx"`>删除a>
* 弹出窗口在最上面
<body onblur="this.focus();">
* 上一页来源
document.referrer
* 没有缓存
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache, must-revalidate">
<META HTTP-EQUIV="expires" CONTENT="Wed, 26 Feb 1997 08:21:57 GMT">
or
<META HTTP-EQUIV="expires" CONTENT="0">
* 不要滚动条
没有竖条
<body style=`overflow:-Scroll;overflow-y:hidden`>
没有横条:
<body style=`overflow:-Scroll;overflow-x:hidden`>
两个都没:
<body scroll="no">
