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，我真正想要的是它仅捕获给定#id内的输入。所以我尝试了

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

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

和

$(formid).('input')

，但没有一个产生任何结果。如何实现在div ID内检索输入？

Answer 1

您可以非常直接地访问输入而无需使用父级$("#idInput")，或者可以通过使用$('#myform1 #idInput')来通过父级访问输入。但是，请确保在生成时已定义元素的ID。

还有另一种方法可以将其用作数组$('#myform1 input')[index]。请注意，索引应该是您输入的所需外观数。

Answer 2

尝试一下：


    $("input").parent( "#myform1" );

Answer 3

正如我在评论中所说，您的JavaScript代码是正确的。但是有两个问题导致您没有任何结果：

#myform1为空白。
在另一种形式中，您有一些input控件，但它们没有任何价值。

下面，我在表单＃myform1中添加了具有一定值的输入并测试了代码：

$('#myform1 input').each(function(index){

     console.log($(this).val()); 
});

<script src="https://code.jquery.com/jquery-2.2.4.min.js"></script>
<form id="myform1"><input value="Some Thing" /></form>
