ajax提交form表单, 序列化表单的参数

                      

                      //var a = $("#addfm").serialize(); //将表单的内容序列化成为一个字符串
                      var a = $("#addfm").serializeArray(); //将表单的内容序列化成为一个对象的数组, 每个对象以name:xxx,value:xxx的键值对存储

              //这两个序列化的参数都是可以传递给后台的代码的

                      $.ajax({
                                        type:"POST",
                                        url:"CmKhxxb/add.do",
                                        data:a,
                                        dataType:"json",
                                        success:function(data) {
                                            if(data.success) {
                                                $("#d_add").dialog("close");
                                                $("#tab1").datagrid("reload");
                                                $.messager.alert("提示","信息已经保存 ! ");
                                            }
                                        },
                                        error: function (msg) {                   //ajax请求失败后触发的方法
                                            var dataJson = eval("("+msg.responseText+")");
                                            alert("错误信息: "+dataJson.reason+"\n状态码: "+msg.readyState);
                                        }
                                    });

 

 

 

时间戳和字符串之间的互相转换

js前台:

1、当前时间换时间戳

var timestamp = parseInt(new Date().getTime()/1000);    // 当前时间戳

 

2、当前时间换日期字符串

var now = new Date();
var yy = now.getFullYear();      //年
var mm = now.getMonth() + 1;     //月
var dd = now.getDate();          //日
var hh = now.getHours();         //时
var ii = now.getMinutes();       //分
var ss = now.getSeconds();       //秒
var clock = yy + "-";
if(mm < 10) clock += "0";
clock += mm + "-";
if(dd < 10) clock += "0";
clock += dd + " ";
if(hh < 10) clock += "0";
clock += hh + ":";
if (ii < 10) clock += ‘0‘; 
clock += ii + ":";
if (ss < 10) clock += ‘0‘; 
clock += ss;
document.write(clock);     //获取当前日期

 

3、日期字符串转时间戳

var date = ‘2015-03-05 17:59:00.0‘;
date = date.substring(0,19);    
date = date.replace(/-/g,‘/‘); 
var timestamp = new Date(date).getTime();
document.write(timestamp);

 

4、时间戳转日期字符串

var timestamp = ‘1425553097‘;
var d = new Date(timestamp * 1000);    //根据时间戳生成的时间对象
var date = (d.getFullYear()) + "-" +
           (d.getMonth() + 1) + "-" +
           (d.getDate()) + " " +
           (d.getHours()) + ":" +
           (d.getMinutes()) + ":" +
           (d.getSeconds());
document.write(date);
