JavaScript ID 选择器

Question

我有 2 个表格

<form name= "form1" action="">
  <input type="hidden" name="max" id= "max1" value="100"/> 
  <input type="submit"  class="submit" value="part 1" />
</form>

<form name= "form2" action="">
  <input type="hidden" name="max2" id= "max2" value="200"/> 
  <input type="submit"  class="submit" value="part 2" />
</form>

我从这里获取表单中的值

         $(".submit").click(function () {

 here  -->       var max_res = $("input#max1").val();
                 var  Results = "Max Result " + max_res;      
         });

我的问题是如何动态地将ID从ma​​x1更改为ma​​x2，以便我可以将ma​​x2的值存储在中max-res 当在 form2 中单击时

Answer 1

 var max_res = $('input[id^="max"]', $(this).parent()).val();
 //selects the id starting with max in this form
 var  Results = "Max Result " + max_res;
