单的JS禁止页面右键菜单--避免网站信息被盗用 代码如下: <script type="text/javascript"> function block(oEvent){ if(window.event) oEvent=window.event; if(oEvent.button==2) alert("鼠标右键不可用"); } document.onmousedown=block; </script> 网页上禁止复制主要靠JavaScript来实现。 <BODY oncontextmenu="return false" onselectstart="return false" ondragstart="return false" onbeforecopy="return false" oncopy=document.selection.empty() onselect=document.selection.empty()> ----------------------------------------------- 防止复制的js ----------------------------------------------- 代码如下: <SCRIPT language=JavaScript1.2> function disableselect(e){ return false} function reEnable(){return true } file://if IE4+ document.onselectstart=new Function ("return false") file://if NS6 if (window.sidebar){ document.onmousedown=disableselect document.onclick=reEnable } </SCRIPT> <SCRIPT language=JavaScript type=text/JavaScript> <!-- function MM_reloadPage(init) { //reloads the window if Nav4 resized if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) { document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }} else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload(); } MM_reloadPage(true); //--> </SCRIPT> ------------------------------------------------------- 防止下载的js ------------------------------------------------------- <noscript><iframe src=""></iframe></noscript> -------------------------------------------------------- 下面是防止右键的js: 代码如下: <script language="JavaScript"> <!-- if (window.Event) document.captureEvents(Event.MOUSEUP); function nocontextmenu() { event.cancelBubble = true event.returnValue = false; return false; } function norightclick(e) { if (window.Event){ if (e.which == 2 || e.which == 3) return false; }else{ if (event.button == 2 || event.button == 3){ event.cancelBubble = true event.returnValue = false; return false; } } } document.oncontextmenu = nocontextmenu; // for IE5+ document.onmousedown = norightclick; // for all others //--> </script> <title>CSS禁止选择和复制</title> <meta http-equiv="content-Type" content="text/html;charset=gb2312"> <style> body{ -moz-user-select:none; hutia:expression(this.onselectstart=function(){return(false)}); （编辑：聊城站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
