本篇文章是对JavaScript禁止页面操作的示例代码进行了介绍,需要的朋友可以过来参考下,希望对大家有所帮助
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)}); } </style> </head> <body> 这里是网页内容,试试您能不能复制? </body> </html> 应用实例: 代码如下: <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>JS控制页面</title> <script language="javascript" type="text/javascript"> //禁止用户使用邮件(隐藏右键菜单) document.oncontextmenu = function forbidRightKey() { window.event.returnValue = false; } //禁止用户使用邮件(提示用户禁用右键) function block() { var oEvent; if (window.event) oEvent = window.event; if (oEvent.button == 2) alert("鼠标右键不可用"); } document.onmousedown = block; //当用户按键AltF4的时候,提示关闭窗口信息 function altF4() { if (window.event.altKey && window.event.keyCode == 115) { window.close(); } } //alt 鼠标左键 组成快捷键 选中文本框中内容 调用方式<body onkeydown="altF4();" > function getTxtSelect(eventControl) { if (eventControl.altKey) { document.getElementById("txt1").select(); } } function clearTxtByInput() { document.getElementById("txtContent").value = ""; } function FillTxtByInput() { document.getElementById("txtContent").value = "输入搜索条件"; } //禁用键盘上的某几个键 调用onkeydown="ForbidKeys();" function ForbidKeys() { var content = window.event.keyCode; if (content >= 65 && content <= 68) { window.event.returnValue = false; } else { window.alert(content); } } //禁止复制网页内容 <body oncopy="forbidCopy();"> function forbidCopy() { window.event.returnValue = false; window.clipboardData.setData("Text", ""); alert("禁止复制网页内容!"); } //设置复制内容 附加 本网站的URL function SetCopyContent() { window.event.returnValue = false; var content = document.title + "/r/n"; content += document.getElementById("txt1").value + "/r/n"; content += "本资源来自 " + this.location.href; window.clipboardData.setData('Text', content); alert("复制成功,请粘贴到你的QQ/MSN上推荐给你的好友"); } //禁止刷新F5 和Ctrl+F5 function ForbidFreshPage() { if ((window.event.ctrlKey && window.event.keyCode == 116) || window.event.keyCode == 116) { window.event.keyCode = 0; window.event.returnValue = false; } } doc
