获取DOM中的所有href链接 [英] Get all href links in DOM

问题描述

我需要编写代码将网页中的所有href链接放入数组中。这是我到目前为止：

  var array = []; 
 var links = document.links; 
 for（var i = 0; i< links.length; i ++）{
 array.push（links [i] .href）; 
} 
  

然而，这不适用于Gmail收件箱等网页，因为有些的链接在iframe中。我如何获得所有链接，包括iframe中的链接？

另外，这也适用于谷歌浏览器扩展。在清单中，我将all_frames设置为true - 这是否有所作为？

谢谢

解决方案

我有一个方法用于访问IFrame中的数据。答案永远不会被写下来阅读和使用：
随意修改和滥用：
$ b $ pre $ public HtmlElementCollection GetIFrameElements（String tmpTag，int Frame）
{
HtmlElementCollection tmpCollection = mWebBrowser.Document.Window.Frames [Frame] .Document.Body.GetElementsByTagName（tmpTag）;
返回tmpCollection;
}


然后我用它来查找任何元素Im：

  foreach（HtmlElement el in GetElements（input））
 {
 if（el.GetAttribute（id ）.Equals（hasNoGoogleAccount））
 {
 el.InvokeMember（click）; 
 
 
 $ / code $ / pre 
 
您可以随时更改方法循环并获取所有的iFrames等等等等，但这应该足以让你感动。

I need to write code that puts all of the href links from a webpage into an array. Here's what I have so far:
var array = [];
var links = document.links;
for(var i=0; i<links.length; i++) {
  array.push(links[i].href);
}
However, this does not work on a page like Gmail's inbox, because the some of the links are within an iframe. How can I get ALL of the links, including the ones inside the iframe?

Also, this is for a google chrome extension. In the manifest, I have all_frames set to true - does this make a difference?

Thanks

I have a method I use to access data in an IFrame. How fun that the answer is never just written down to read and use :P.
Feel free to modify and abuse:
public HtmlElementCollection GetIFrameElements(String tmpTag, int Frame)
    {
        HtmlElementCollection tmpCollection = mWebBrowser.Document.Window.Frames[Frame].Document.Body.GetElementsByTagName(tmpTag);
        return tmpCollection;
    }
I then use it to look for whatever element Im after:
foreach (HtmlElement el in GetElements("input"))
        {
            if (el.GetAttribute("id").Equals("hasNoGoogleAccount"))
            {
                el.InvokeMember("click");
            }
        }
You could always change the method to loop through and get all iFrames etc blah blah but that should be enough to get you moving.
Rate me! Im new
