jQuery获取ModelMap值

时间:2025-02-15 08:34:55

Controller

 @GetMapping("/edit/{id}")
 public String edit(@PathVariable("id") Long id, ModelMap mmap)
 {
        List<Test> testList= (id);
        ("testList", testList);
        return prefix + "/edit";
 }

[[${testList}]]可取出从controller传过来的testList对象,该功能实现了对查询到的testList集合里的所有Test对象的value值的累加,并把最后累加值赋予input。

......

<input name="totalValue" value="0" style=" border-width:0;color:red;" class="form-control" type="text" maxlength="30" readonly="readonly">

......

function sumAmount(){
     var totalAmount = 0;
     for(var i = 0; i < [[${testList}]].length; i++){
          var result = [[${testList}]][i];
          totalAmount = accAdd(totalAmount, );
     }
     $("input[name='totalValue']").val(totalAmount);
}
