javascript - C# javascript 通过标签和属性点击按钮

Question

我在让我的程序点击按钮时遇到一些问题:

 <a class="button_recruit" style="letter-spacing: -1px" href="/myrecruitlink" data-executing="0">Recruit</a>      

这是我尝试单击的按钮，但是当我为其添加代码时它什么也没做，我是 C# 的新手并正在尝试学习它。因此，如果有人能指出我在这里做错了什么，我将不胜感激。

程序代码如下:

 namespace clean_test
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        web.ScriptErrorsSuppressed = true;
        Registry.SetValue("HKEY_CURRENT_USER\\AppEvents\\Schemes\\Apps\\Explorer\\Navigating\\.Current", "", "NULL");
        web.Navigate("http://www.mywebsite.com");
    }

    private void recruit_Click(object sender, EventArgs e)
    {
        HtmlElementCollection elems = web.Document.GetElementsByTagName("a");
        foreach (HtmlElement elem in elems)
        {
            String value = elem.GetAttribute("value");
            if (value != null && value.Length != 0 && value.Equals("Recruit"))
            {
                recruit.PerformClick();
            }
        }
    }


  }
}

我认为其他人不理解您的问题。你需要这一行:

private void recruit_Click(object sender, EventArgs e)
{
     HtmlElementCollection elems = web.Document.GetElementsByTagName("a");
     foreach (HtmlElement elem in elems)
     {
         String value = elem.GetAttribute("value");

         //you can use elem.InnerText.Equals("Recruit") too, if value == null.
         if (value != null && value.Length != 0 && value.Equals("Recruit"))
         {
             elem.InvokeMember("click");
         }
     }
 }

希望能帮到你!
