从tom大叔那想着拿书的，呵呵。

//var tgtttime = new Date("2014/05/26 09:59:30");
var tgtttime = new Date("2014/05/26 13:59:45");
var yyyy1111 = setInterval(function(){
    var now = new Date();
    console.log(now);
    if (now>=tgtttime) {
        var yager1111 = setInterval(function() {
            $.ajax({
                url: "/mvc/PostComment/Add.aspx",
                data: JSON.stringify({
                    blogApp: "TomXu",
                    postId: cb_entryId,
                    body: "抢书，拿下，好书一定要拿下啊",
                    parentCommentId: 0
                }),

                }
            });
        }, 20);

        setTimeout(function(){

            clearInterval(yyyy1111);

            }, 22000);

        
    }

}, 20000);
