使用原生js写ajax实例(推荐)

var html = document.getElementsByTagName("html")[0];
html.onclick = function(){
ga_ajax({
"method" : "post","url" : "demo.php","data" : {
"name" : "gao","age" : 100,"num" : "12346&598"
},"success" : function(data){
alert(data);
},"Error" : function(text){
alert(text);
},"async" : false
});
}
