最近做的一个项目，从后台查询到日期数据传到前台JS中遍历之后显示的是以"14"开头的毫秒数，刚开始想用"simpleDateFormat"类处理，结果显示都不显示了。后来查了一下资料，感觉其实很简单，下面 把自己的方法分享给大家以供参考。
1.显示的毫秒数
2.处理之前的样式
3.处理之后的样式
Date.prototype.toLocaleString = function() { return this.getFullYear() + "-" + (this.getMonth() + 1) + "-" + this.getDate() + " " + this.getHours() + ":" + this.getMinutes() + ":" + this.getSeconds(); }; success:function(data){ var Str=""; var length = data.length; for(var i=0;i<length;i++){ //Str += '<tr><td>'+data[i].roleId+'</td><td>'+data[i].roleName+'</td><td>'+data[i].remarks+'</td><td>'+data[i].createBy+'</td><td>'+data[i].createDate+'</td><td>'+data[i].updateBy+'</td><td>'+data[i].updateDate+'</td><td>'+data[i].status+'</td></tr>'; Date.prototype.toLocaleString = function() { return this.getFullYear() + "-" + (this.getMonth() + 1) + "-" + this.getDate() + " " + this.getHours() + ":" + this.getMinutes() + ":" + this.getSeconds(); }; Str += "<tr>" + "<td class=\"tbody_check\">" + "<span class=\"check\">" + "<input type=\"checkbox\" value=\""+data[i].roleId+"\" name=\"checkbox\">" + "</span>" + "</td>" + "<td>" +data[i].roleId+"</td>" + "<td>" +data[i].roleName+"</td>" + "<td>" +data[i].remarks+"</td>" + "<td>" +data[i].createBy+"</td>" + "<td>" +new Date(data[i].createDate).toLocaleString()+"</td>" + "<td>" +data[i].updateBy+"</td>" + "<td>" +new Date(data[i].updateDate).toLocaleString()+"</td>" + "<td>" +data[i].status+"</td>" + "</tr>"; } $("#rolelist").html(Str); }
