找到包含元素的表单？ [英] Find form that contains element?

问题描述

我在表单中有一个元素，它们之间可能有很多元素。有一个指向我元素的变量，我想知道如何在变量中获得父窗体。

I have an element inside a form, there might be many elements between them. Having a variable pointing to my element, I want to know how to get the parent form in a variable.

EG：

<form>
  <div>
    //Element
  </div>
</div>

因此，有 var元素指向一个元素在divs里面，我怎样才能得到包含它的表单？

So having var element pointing to an element inside the divs, how can I get the form that contains it?

我正在考虑循环父母直到找到表单，但我想知道是否有更简单的方法如何获得表单元素？

I'm thinking on looping through parents until finding a form, but I want to know if there's an easier way. How can I get the form element?

推荐答案

使用Javascript函数来实现这一点：

Javascript function to achieve this :

function ParentForm(element){ 
  var parent = elem.parentNode; 
  if(parent && parent.tagName != 'FORM'){
     parent = findParentForm(parent);
     }
  return parent;
}
var myForm = parentForm(myElement)
