jQuery Ajax 等

• Ajax

// xhr  =XMLHttpRequest// jqXhr=jQueryXMLHttpRequest// ts   =textStatus// et   =errorThrown$.ajax({    async:true,      //是否异步    type:"post",    traditional:true,//true a[]=1&a[]=2, false a=1&a=2    url:"",    data:{},    dataType:"json", //text,html,xml,script,json,jsonp    beforeSend:function(jqXhr){}//return false 不发送    dataFilter:function(data,type){return data;},//对Ajax返回的原始数据进行预处理    success:function(data,ts,jqXhr){},    error:function(jqXhr,ts,et){},    complete:function(jqXhr,ts){}});

• Html 弹框

alert();confirm();prompt();
