c# - 如何通过 GetElementByClass 选择一个类并以编程方式单击它

Question

我一直在尝试使用此代码在 html/ajax 中按类读取元素，因为我知道 GetElementByClass 不是 webBrowser.Document 中的一个选项。我似乎无法获得返回值然后调用该成员。有解决办法吗？

引用资料: Getting HTMLElements by Class Name

例子:

<span class="example">(<a href="http://www.test.com/folder/remote/api?=test" onclick=" return do_ajax('popup_fodder', 'remote/api?=test', 1, 1, 0, 0); return false; " class="example">test</a>)</span>

示例代码:

   HtmlElementCollection theElementCollection = default(HtmlElementCollection);
   theElementCollection = webBrowser1.Document.GetElementsByTagName("span");
   foreach (HtmlElement curElement in theElementCollection)
   {
        //If curElement.GetAttribute("class").ToString = "example"  It doesn't work.  
        // This should be the work around.
        if (curElement.OuterHtml.Contains("example"))
        {
            MessageBox.Show(curElement.GetAttribute("InnerText")); // Doesn't even fire.
            // InvokeMember(test) after class is found.
        }
    }

我承认这不是很直观，但您需要使用 GetAttribute("className") 而不是 GetAttribute("class")

HtmlElementCollection theElementCollection = default(HtmlElementCollection);
theElementCollection = webBrowser1.Document.GetElementsByTagName("span");
foreach (HtmlElement curElement in theElementCollection)
{
    if (curElement.GetAttribute("className").ToString() == "example")
    {
        MessageBox.Show(curElement.GetAttribute("InnerText")); // Do something you want
    }
}
