JS は dom オブジェクトの取得、ajax 操作、Cookie の読み取りおよび書き込み関数_javascript スキルを取得します。

コードをコピー コードは次のとおりです:

var LF = {};
LF.version = '1.0.0';
//全局関数数
function $(objName) {
return document.getElementById(objName);
}
function $name(objName) {
return document.getElementsByName(objName);
}
function $tag(objName) {
return document.getElementsByTagName(objName);
}

//广告swf flashWrite('SW/2009/HomeGroBuy.swf','950','70','navigation', '##ffffff', 'menuNum=0', '透明'）;
function flashWrite(url,w,h,id,bg,vars,win){
var flashStr=
"

";
document.write(flashStr);
}
//广告图片 imgWrite('images/pic04.jpg', '780', '90', 'http://www.lfang.com/wzzt/2009/lgzt/');
function imgWrite(url,w,h,linkUrl){
var flashStr= "";
if (linkUrl=="")
flashStr="" ;
else
flashStr="" "" "";
document.write(flashStr);
}
//AJAX オペレーション
LF.ajax={
getXmlhttp : function() {
var http_request;
if(window.XMLHttpRequest) {
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType("text/xml");

try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
window.alert("XMLHttpRequest オブジェクトを作成できません。");
null を返します。
}
http_request を返す;
},
