如何识别儿童输入类型
原标题:how to identify children input type

基本上我有几个div,每个div都包含一个问题。这个问题可以通过单个输入、单选按钮或复选框来呈现。

当循环遍历div时,我想确定输入类型是什么。

以下实现这一点的代码不起作用,只是试图展示我想要实现的目标。

$(".question").each(function(){

        var type = $(this).children( input ).attr("type").val();
        alert(type);
});
最佳回答

移除阀():

  var type = $(this).children( input ).attr("type");

例如。

  $(document).ready(function(){
      $( button ).click(function(){$(".question").each(function(){

         var type = $(this).children( input ).attr("type");
         alert(type);
        });
      });
  });


 <div class="question">
  <input type="radio">hello</input>
 </div>

 <div class="question">
   <input type="checkbox">hello</input>
 </div>

 <div class="question">
   <input type= text  name= response[4][answer] ></input>
 </div>

 <button>Click</button>
问题回答

现场演示

$(".question > input").each(function(){
        var type = $(this).attr("type");
        alert(type);
});

var type=$(this).find(“input”).get(0).type

这应该会让你开始:

$( div ).each(function(){
    $(this).children( input ).each(function(){
       alert($(this).attr( type ));   
    });
});
