json时间字符串带T格式化

Date.prototype.pattern = function (fmt) {
    var o = {
        "M+": this.getMonth() + 1, //月份
        "d+": this.getDate(), //日

        "H+": this.getHours(), //小时
        "m+": this.getMinutes(), //分
        "s+": this.getSeconds(), //秒
        "q+": Math.floor((this.getMonth() + 3) / 3), //季度    
        "S": this.getMilliseconds() //毫秒    

    };

// 例如

var createTime="2018-07-23T10:31:56.080";
var date=new Date(createTime.replace('T', " ")).pattern("yyyy-MM-dd hh:mm:ss")
