jQuery-更改子级的iframe宽度

Question

I am facing a problem that I need to change the width of an iframe in a child node.

For example:

<div id="pNode">
  <div>
      <iframe>...</iframe>
  </div>
</div>

There are no IDs for childnode and iframe. How can I change the width?

Answer 1

只需假设问题中的结构，选择iframe：

$('#pNode div iframe').attr('width',/* Your width */)
