使用网页浏览器点击一个按钮在网页中 [英] Using webbrowser to click on a button in a webpage

问题描述

所以我需要做的就是用这个code：

so what I need to do is to use this code:

WebBrowser browser = new WebBrowser();
browser.Navigate("www.somthing.com");
browser.Document.GetElementById("ID").InvokeMember("click");

然后我需要找到在页面的按钮的ID，并把我的code，但我的问题是一些按钮没有标识的！我该怎么办呢？他们只有类型和类和其他一些东西，但没有编号。我意识到，有些按钮可能是java，也许这就是为什么我不能在上面点击由通常的方式。所以你知道我应该怎么办？

and then i need to find the id of the button in the page and put in my code but my problem is some of the buttons don't have Id's! what should I do then? they only have type and class and some other things but no Id. i realized that some buttons might be java and maybe that's why i can't click on them by the usual way. so do you know what should I do?

推荐答案

您说您的按钮元素有一个的className ，你可以这样得到这个元素：

You said your button element has a className ,you can get this element with like this:

public Form1()
        {
            InitializeComponent();
            webBrowser1.Navigate("To your register account url");
        }
        int on = 0;
        private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            foreach (HtmlElement btn in webBrowser1.Document.GetElementsByTagName("button"))
            {
                if (btn.GetAttribute("className") == "yourclassname")
                {
                    btn.InvokeMember("Click");
                    break;
                }
            }
        }
