一个轻量级的XHTML右键菜单[支持IE和firefox]_javascript技巧

目前很多在网络上流传的右键菜单都不支持XHTML，主要就是因为document.body和document.documentElement之间的不同造成的 
还有一个就是很多右键菜单程序太大，于是自己写了一个迷你型的右键菜单，支持IE和firefox

<title>adad</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <style> #rightMenu{ padding:2px; background-color:menu; cursor:default; position:absolute; z-index:900; border-right:1px solid #aaa; border-bottom:1px solid #aaa; border-top:1px solid #fff; border-left:1px solid #fff; font-size:14px; word-break:keep-all; } .menuItem{ display:block; padding:3px; } </style> <script> /** *JRightMenu类，在浏览器里显示用户定制右键菜单 *[注意]：只适用于XHTML *@author brull *@email brull@163.com *@date 2007-01-24 */ /** *@param menuItem 菜单显示内容，是一个数组 *@param handle 对应menuItem菜单的处理js代码段，同样是个数组 */ JRightMenu=function (menuItem,handle){ var rightMenu=document.createElement("div"); var menuInnerHTML="";//菜单容器里的HTML内容 var $items=this.menuItem=menuItem; var $handle=this.handle=handle; rightMenu.id="rightMenu";//id for(var i in $items){ if($items[i].indexOf("<hr")!=-1) menuInnerHTML+=$items[i]; else menuInnerHTML+="<span class=&#146;menuItem&#146; onmouseover=&#146;this.style.backgroundColor=\"#3e80ca\";window.status=this.innerHTML;&#146; onmouseout=&#146;this.style.backgroundColor=\"\";window.status=\"\"&#146; onclick=\""+handle[i]+"\" >" +$items[i] +""; } rightMenu.innerHTML=menuInnerHTML; rightMenu.style.visibility = "visible"; rightMenu.onmousedown=function(e){ e=e||window.event; document.all?e.cancelBubble=true:e.stopPropagation(); } rightMenu.onselectstart=function(){ return false; } document.body.appendChild(rightMenu); this.menu=rightMenu;//方便别的方法引用 }; JRightMenu.prototype.show=function(e){ e=e||window.event; var root=document.documentElement; var x = root.scrollLeft+e.clientX;//菜单左上角横坐标 var y = root.scrollTop+e.clientY;//菜单左上角纵坐标 if (this.menu.clientWidth+e.clientX > root.clientWidth){ x=x-this.menu.clientWidth; } if (this.menu.clientHeight+e.clientY > root.clientHeight){ y=y-this.menu.clientHeight; } this.menu.style.left = x+"px"; this.menu.style.top = y+"px"; this.menu.style.visibility = "visible"; return false; } JRightMenu.prototype.hidden=function() { this.menu.style.visibility = "hidden"; } </script> <script> window.onload=function(){ rightMenu=new JRightMenu(["it&#146;s mine!","it&#146;s yours!"],["alert(&#146;it is mine!&#146;)","alert(&#146;it is yours!&#146;)"]); } document.oncontextmenu=function(evt){return rightMenu.show(evt);}; document.onclick=function(){rightMenu.hidden();} </script> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> <p>adadad大王大王</p> awdddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd
