Javascript代码：将链接的查询参数变为name=value的形式

/**//*

functiongetArgs()...{
varargs=newObject();
varquery=location.search.substring(1);//Getquerystring.
varpairs=query.split(",");//Breakatcomma.
for(vari=0;i<pairs.length;i++)...{
varpos=pairs[i].indexOf('=');//Lookfor"name=value".
if(pos==-1)continue;//Ifnotfound,skip.
varargname=pairs[i].substring(0,pos);//Extractthename.
varvalue=pairs[i].substring(pos+1);//Extractthevalue.
args[argname]=unescape(value);//Storeasaproperty.
//InJavaScript1.5,usedecodeURIComponent()insteadofescape()
}
returnargs;//Returntheobject.
}
