通过C#模拟html中的点击图片 [英] simulate click image in html through c#

问题描述

你好
我正在编写某个网站的剪贴程序，用户必须输入搜索条件，然后单击gif图片...
在页面的html代码中，该图像仅具有以下属性:

Hello
i''m writing a scrapping program of some site ,and there user has to enter search criteria and then click on an gif image...
in the html code of the page , that image has this properties only:

<input type="image" src="/esignalprod/images/go.gif" border="0"/>

如您所见...没有id，没有名称...
如何找到该特定图像，当找到该图像时，如何模拟单击它?

谢谢你

推荐答案

试试这个

Hi ,
Try this

protected void Page_Load(object sender, EventArgs e)
  {
      img1.ServerClick += new ImageClickEventHandler(img1_ServerClick);
  }

  void img1_ServerClick(object sender, ImageClickEventArgs e)
  {
      Response.Write("<script>alert('test')</script>");
  }

<input type="image" src="/esignalprod/images/go.gif" border="0" id="img1" runat="server"/>

最好的问候
