访问iframe中的表单 [英] accessing a form that is in an iframe

问题描述

我试图访问表单及其元素。表单位于iframe中，访问表单的JavaScript代码位于主文档中。

我不确定还有什么我应该加入问题的，所以请让我知道是否需要添加别的东西。

（表单和主页在同一个域中）

谢谢

解决方案

  var ifr = document.getElementById（yourIframeId）; 
 var ifrDoc = ifr.contentDocument || ifr.contentWindow.document; 
 var theForm = ifrDoc.getElementById（yourFormId）; 
  

或者您可以在框架中设置一些代码，在父项中设置一个变量添加到表单中，但我不相信该方法。

I'm trying to get access to a form and its elements. The form is within an iframe and the javascript code that is accessing the form is within the main document.

I'm not sure what else I should put into the question, so please let me know if I need to add something else.

(form and main page are in the same domain)

Thanks

解决方案

var ifr = document.getElementById( yourIframeId );
var ifrDoc = ifr.contentDocument || ifr.contentWindow.document;
var theForm = ifrDoc.getElementById( yourFormId );

Or you could have some code in the frame that sets a variable in parent to the form, but I wouldn't trust that method.
