javascript方法库 不知道写什么了

for in遍历对象

function ob(a){var b="";for(var p in a){b+=p+"="+a[p]+"/r";}return b};

Ajax

function ajax(a){

var x;

x=window.xmlHttPRequest?new xmlhttpRequest():new ActiveXObject("Microsoft.XMLHTTP");

x.open(a.type,a.url,a.async);if(a.type=="POST"){x.setRequestHeader('Content-type', 'application/x-www-form-urlencoded')};a.c?x.send(a.c):x.send();

return x.responseText}

获取网址中的参数

function getArgs(str){var a='',i,n,t=str.split("&");for(i=1;i<t.length;i++){n=t[i].split("=");a+=n[0]+':"'+n[1]+'",';}return eval('({'+a+'})')}

Object。prototype.$=function (){var a=arguments[0],b=a.charAt(0),c=a.substr(1,a.length),d=document;

return b=="#"?d.getElementById(c):(b=="."?d.getElementsByClassName(c):d.getElementsByTagName(c))}
