js代码添加事件监听，常用jq方法

var btn1 = document.getElementById("btn1");

btn1.addEventListener("click", function() {

    alert("为被点击了");

});

 

 

//给保存按钮添加事件
$("#productStockAddBtn").on("click",alert(warehouseId));

 

jq获取style中的属性
$("p").css("background-color");//获取p元素的背景颜色
$("p").css("background-color","yellow");//设置p元素的背景颜色为黄色

 

jq改变class
$(".aa:odd").removeClass().addClass("BB");

// layer 打开模态框
/* $(function(){
    $('.editCatalogBtn').click(function(){
        layer.open({
          type: 1,
          area:['500px','auto'],
          title: '编辑商品目录',
          closeBtn: 1,
          shadeClose: true, //开启遮罩关闭
          anim:0,
          btn:['确定','取消'],
          content: $(".editCatalogBox")
        });
    })
})  */

//
jConfirm("确认修改!",function(){
                        $.post("/catalog/updataCatalogInfo",
                                $("#editCatalogForm").serialize(),
                                function(rs){
                                    if(rs.code==0){
                                       jSuccess(rs.msg,function(){
                                           location.reload(true);//刷新页面
                                       });
                                       
                                    }else {
                                       jFail(rs.msg);
                                }
                        });

解决后台传前台的格式
String ls；
前台取ls
public void setLastTime(Date lastTime) {
        this.ls = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(lastTime);
        this.lastTime = lastTime;
    }
