JS實作很酷的EMAIL位址新增功能實例_javascript技巧

本文實例講述了JS實現很酷的EMAIL位址添加功能的方法。分享給大家供大家參考。具體實作方法如下：

複製程式碼 程式碼如下: JS实现很酷的EMAIL地址添加功能 ul{ list-style:none; margin:0; padding:0;} li{ margin:0; padding:0;} #content{width:100%;} #sendmail{float:left; width:60%;} #friendlist{float:left; width:30%;} #bxAddrFly{position:absolute;height:18px; width:46px;background:#EEE; border:1px #ccc solid;display:none;} #tbAddrTree{ width:126px; float:left; padding:5px;border:1px #7F9DB9 solid;} #tbAddrTree li{ width:100%; float:left;} #tbAddrTree a{backgroud: #fff;width: 100%;color:#494949;text-decoration: none;float:left;} #tbAddrTree a:hover{background: #e5edf6;} var ev={}; var flyDiv="bxAddrFly"; var inceptDiv="SendAddress"; var addEvent="addAddress()"; function oo(obj){return (document.getElementById) ? document.getElementById(obj): document.all[obj];} function isNone(str){return str==null||str==""?true:false} var Browser = new Object(); Browser.isFirefox = (navigator.userAgent.toLowerCase().indexOf("firefox")!=-1); if (Browser.isFirefox) { extendEventObject();} function extendEventObject() { window.constructor.prototype.__defineGetter__("event", function(){ var o = arguments.callee.caller; var e; while(o != null){ e = o.arguments[0]; if(e && (e.constructor == Event || e.constructor == MouseEvent)) return e; o = o.caller; } return null; }); Event.prototype.__defineGetter__("srcElement", function () { var node = this.target; while (node.nodeType != 1) node = node.parentNode; return node; }); } window.onload = function(){ var addrTree = oo('tbAddrTree'); addrTree.onmouseover = function(){addrTree_event(event)}; addrTree.onmouseout = function(){addrTree_event(event)}; addrTree.onclick = function(){addrTree_event(event)}; } function addrTree_event(e){ var memberID,tr var ee = e.srcElement; if(ee.tagName=="A"&&e.type=="mouseover"){ee.style.textDecoration="underline"} if(ee.tagName=="A"&&e.type=="mouseout"){ee.style.textDecoration=""} if(e.type=="click"&&e.srcElement.tagName=="A"){ var li=ee.parentNode.parentNode; ev.AddInfo="\""+li.getAttribute("memberName")+"\" " oo(flyDiv).innerHTML=li.getAttribute("memberName"); addrTree_add(e.clientX,e.clientY) } } function addrTree_add(ex,ey){ if(oo(flyDiv).style.display=='none'||oo(flyDiv).style.display==''){oo(flyDiv).style.display='block';} var inceptE = oo(inceptDiv); var inceptEX = inceptE.offsetTop; var inceptEY = inceptE.offsetLeft; while(inceptE = inceptE.offsetParent){ inceptEX += inceptE.offsetTop; inceptEY += inceptE.offsetLeft; } ev.flyArr=new Array(ex,ey,inceptEX,inceptEY,10); fly(flyDiv,addEvent); }

function fly(flyObj,flyRun){ var obj,a=ev.flyArr,x,y if(flyObj!=null){ if(ev.flyObj!=null){ window.clearTimeout(ev.flyTm); ev.flyObj.style.top=-900; } a[5]=0; ev.flyObj=oo(flyObj); ev.flyRun=flyRun; }
