            </td>
        </tr>


        <tr class="spacer"></tr>

    </tbody>

</table>

并且我有一个从动态创建的html触发的函数。

function postitem(index) {
   var formid='#myform'+index

    $('input').each(function(index){

     console.log($(this).val()); 
 });
}

选择器$(' input ')捕获html中的所有输入值，我真正想要的是让它只捕获给定#id内的输入。所以我试着

 $('#myform1 input').each(function(index){

     console.log($(this).val()); 
 });

和

$(formid).('input')

它们都没有产生任何结果。如何实现在div id中检索输入？

javascript

jquery

html

您可以在不使用父$("#idInput")的情况下直接访问输入，或者可以使用$('#myform1 #idInput')通过父use访问它。但是要确保在生成时已经定义了元素的ids。

还有另一种方法，你可以使用它作为数组$('#myform1 input')[index]。注意:索引应该是您的输入所需的出现次数。
