需要准备的材料分别有：电脑、浏览器、html编辑器。
1、首先，打开html编辑器，新建html文件，例如：index.html，输入问题基础代码。
2、在index.html中的<body>标签中，输入js代码：
function fun() {
alert('click success!')
}
3、浏览器运行index.html页面，此时点击按钮弹出了提示框。
弹窗代码js怎么改能弹出多个页面代码如下: //至强弹窗代码//容错脚本functionblockError(){returntrue}//当脚本出错时返回真window.onerror=blockErrorif(window.SymRealWinOpen){window.open=SymRealWinOpen}if(window.NS_ActualOpen){window.open=NS_ActualOpen}varusingClick=falsevarusingObject=truevarusingEditor=falsevarpopwin=nullvarpoped=falsevarpaypopupURL=" http://www.baidu.com"if(typeof(contextualAds)=='undefined'){varcontextualAds=''}if(!document.getElementById('paypopupScriptDiv')){document.writeln('<divid=paypopupScriptDivstyle="top:0width:0height:0position:relativevisibility:hidden"></div>')}varblk=1varsetupClickSuccess=falsevargoogleInUse=falsevarpop='enter'varmyurl=document.location.protocol "//" document.location.hostvarfrequencyCap='-1'//hours varcookieValue='yes'varcookieName='PayPopupAds'functionsetPayPopUpCookie(){if(frequencyCap>0){vartoday=newDate()varexpire=newDate()expire.setTime(today.getTime() 3600000*frequencyCap)document.cookie=cookieName "=" escape(cookieValue) "expires=" expire.toGMTString() "path=/"}elseif(frequencyCap==0){document.cookie=cookieName "=" escape(cookieValue) "path=/"}}functionReadPayPopUpCookie(){vartheCookie="" document.cookievarind=theCookie.indexOf(cookieName)if(ind==-1||cookieName=="")return""varind1=theCookie.indexOf('',ind)if(ind1==-1)ind1=theCookie.lengthreturnunescape(theCookie.substring(ind cookieName.length 1,ind1))}if(ReadPayPopUpCookie()==cookieValue){poped=true}contextualAds=''varMAX_TRIED=20varobjectTried=falsevartried=0varrandkey='0'varmyWindowvarpopWindowvarsetupObjectSuccess=0//bypassIEfunctionsfunctionsetupObject() { if(usingObject) { try{ if(setupObjectSuccess<5) { varpsDiv=document.getElementById('paypopupScriptDiv')if(psDiv) { psDiv.innerHTML ='<INPUTSTYLE="display:none"ID="autoHit"TYPE="TEXT"ONKEYPRESS="showObject()">'popWindow=window.createPopup()popWindow.document.body.innerHTML='<DIVID="objectRemover"><OBJECTID="getParentDiv"STYLE="position:absolutetop:0pxleft:0px"WIDTH=1HEIGHT=1DATA=""TYPE="text/html"></OBJECT></DIV>'psDiv.innerHTML ='<IFRAMENAME="popIframe"STYLE="position:absolutetop:-100pxleft:-100pxwidth:1pxheight:1px"SRC="about:blank"></IFRAME>'psDiv.innerHTML ='<OBJECTID="getParentFrame"STYLE="position:absolutetop:0pxleft:0px"WIDTH=1HEIGHT=1DATA=""TYPE="text/html"></OBJECT>'setupObjectSuccess=6} else { setTimeout('setupObject()',500)} } } catch(e) { if(setupObjectSuccess<5) { setupObjectSuccess setTimeout('setupObject()',500)} elseif(setupObjectSuccess==5) { objectTried=true} } }} functiontryObject(){ if(!objectTried以下代码能实现父窗口关闭子窗口 建a.htm b.htm c.js 三个文件 根据需要改一下就行了 a.htm ---------------------------------------- <html><title>main</title><script language=javascript src="c.js"></script><body>主窗口 <br><br><input type="button" value="b" onclick="window.openSub('b.htm', '__b__', 'width=400,height=300')"><br><br><input type="button" value="关闭窗口" onclick="window.closeSub()"></body></html> b.htm ----------------------------------------------- <html><title>sub11</title><script language=javascript src="c.js"></script><body>子窗口 11 <br><br><input type="button" value="d" onclick="window.openSub('d.htm', '__d__', 'width=400,height=300')"><br><br><input type="button" value="关闭窗口" onclick="window.closeSub()"></body></html> c.js --------------------------------------------- var __winRoot__ = top || parent || window// 祖先窗口对象 var __winParent__ = __winRoot__// 父窗口对象（默认为祖先窗口） var __winTree__ = {subWinNames:''}// 本窗口的子窗口对象集合。 subWinNames 记录所有子窗口的名称，方便遍历 //-------------------------------------------------------- window.closeSub = function() { __winTree_closeAllSubWins__()// 关闭所有子窗口 __winTree_closeWin__()// 关闭当前窗口 } window.openSub = function(url, wname, property) { __winTree_openSubWin__(url, wname, property)} window.onbeforeunload = function() { var n = window.event.screenX -
