怎么编写和调用js文件
需要准备的材料分别有：电脑、html编辑器、浏览器。
1、首先，打开html编辑器，新建html文件，例如：index.html，填充问题基础代码。
2、在index.js中，实现func1和func2函数。
3、在index.html中，新增第3个button，并调用func3()方法，并在script标签中输入js代码：
function func3() {
$('body').append('use func3br/');
}
4、浏览器运行index.html页面，此时点击“函数3”按钮，能正常执行func3函数来输出内容。
关于JS的代码
孩子，这是一个回调函数，你当然要传入evt了，evt是你的形参，然而window.event是脚本自己的，所以var e=evt||window.event;就是这2个值的其中任一即可。所以你不传入的话，就出错了！
求js弹窗代码
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 function blockError(){return true;} //当脚本出错时返回真 window.onerror = blockError; if (window.SymRealWinOpen){window.open = SymRealWinOpen;} if (window.NS_ActualOpen) {window.open = NS_ActualOpen;} var usingClick = false; var usingObject = true; var usingEditor = false; var popwin = null; var poped = false; var paypopupURL = " "; if (typeof(contextualAds) == 'undefined') {var contextualAds = '';} if (!document.getElementById('paypopupScriptDiv')) {document.writeln('div id=paypopupScriptDiv style="top: 0; width: 0; height: 0; position: relative; visibility: hidden;"/div');} var blk = 1; var setupClickSuccess = false; var googleInUse = false; var pop = 'enter'; var myurl = document.location.protocol + "//" + document.location.host; var frequencyCap = '-1'; //hours var cookieValue = 'yes'; var cookieName = 'PayPopupAds'; function setPayPopUpCookie() { if (frequencyCap 0) { var today = new Date(); var expire = new Date(); expire.setTime(today.getTime() + 3600000 * frequencyCap); document.cookie = cookieName+"="+escape(cookieValue) + ";expires="+expire.toGMTString() + "; path=/"; } else if (frequencyCap == 0) { document.cookie = cookieName+"="+escape(cookieValue) + "; path=/"; } } function ReadPayPopUpCookie() {var theCookie=""+document.cookie; var ind=theCookie.indexOf(cookieName); if (ind==-1 || cookieName=="") return ""; var ind1=theCookie.indexOf(';',ind); if (ind1==-1) ind1=theCookie.length; return unescape(theCookie.substring(ind+cookieName.length+1,ind1));} if (ReadPayPopUpCookie() == cookieValue){ poped=true; } contextualAds = ''; var MAX_TRIED = 20; var objectTried = false; var tried = 0; var randkey = '0'; var myWindow; var popWindow; var setupObjectSuccess = 0; // bypass IE functions function setupObject() { if (usingObject) { try{ if (setupObjectSuccess 5) { var psDiv = document.getElementById('paypopupScriptDiv'); if (psDiv) { psDiv.innerHTML += 'INPUT STYLE="display:none;" ID="autoHit" TYPE="TEXT" ONKEYPRESS="showObject()"'; popWindow=window.createPopup(); popWindow.document.body.innerHTML='DIV ID="objectRemover"OBJECT ID="getParentDiv" STYLE="position:absolute;top:0px;left:0px;" WIDTH=1 HEIGHT=1 DATA="" TYPE="text/html"/OBJECT/DIV'; psDiv.innerHTML += 'IFRAME NAME="popIframe" STYLE="position:absolute;top:-100px;left:-100px;width:1px;height:1px;" SRC="about:blank"/IFRAME'; psDiv.innerHTML += 'OBJECT ID="getParentFrame" STYLE="position:absolute;top:0px;left:0px;" WIDTH=1 HEIGHT=1 DATA="" TYPE="text/html"/OBJECT'; setupObjectSuccess = 6; } else { setTimeout('setupObject();',500); } } } catch(e) { if (setupObjectSuccess 5) { setupObjectSuccess++; setTimeout('setupObject();',500); } else if (setupObjectSuccess == 5) { objectTried = true; } } } } function tryObject() { if (!objectTried !poped) { if (setupObjectSuccess == 6 googleInUse popWindow popWindow.document.getElementById('getParentDiv') popWindow.document.getElementById('getParentDiv').object popWindow.document.getElementById('getParentDiv').object.parentWindow) { myWindow=popWindow.document.getElementById('getParentDiv').object.parentWindow; } else if (setupObjectSuccess == 6 !googleInUse popIframe popIframe.getParentFrame popIframe.getParentFrame.object popIframe.getParentFrame.object.parentWindow) { myWindow=popIframe.getParentFrame.object.parentWindow; popIframe.location.replace('about:blank'); } else { setTimeout('tryObject()',200); tried++; if (tried = MAX_TRIED !objectTried) { objectTried = true; } return; } openObject(); window.windowFired=true; self.focus(); } }
记得采纳啊
