我需要帮助才能获得Dotnetbrowser发布的表单数据。 事实上,我想在按钮上添加一个监听器事件,当点击这个按钮时,我得到了数据,例如:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<body>
<h1>Hello!!!</h1><br>
<form
id="formTrying"
method="post"
action="http://localhost/MyWebSite/MyMvcView?MyQueryStringParam1=something&Param2=something"
>
<input name="txtSomething" type="text" value="Trying something..."><br>
<input type="submit" value="Submit...">
</form>
</body>
</html>
当我点击提交按钮时,我从“txtSomething”获取值。 或者当dotnetbrowser检测到表单提交时,我从“txtSomething”中获取值。
提前致谢。 ;)

您可以尝试为相应的DOM元素注册OnClick
事件侦听器,以便获得有关点击的通知。
在您的情况下,可以按如下所示完成:
browser.FinishLoadingFrameEvent += delegate (object sender, FinishLoadingEventArgs e)
{
if (e.IsMainFrame)
{
DOMDocument document = e.Browser.GetDocument();
List<DOMNode> inputNodes = document.GetElementsByTagName("input");
DOMInputElement submitElement = (DOMInputElement)inputNodes.LastOrDefault();
DOMEventHandler domEvent = delegate (object s, DOMEventArgs args)
{
//Obtain the value of the txtSomething field
DOMInputElement txtSomethingElement = (DOMInputElement)document.GetElementByName("txtSomething");
string value = txtSomethingElement.Value;
Console.Out.WriteLine("txtSomething value = " + value);
};
submitElement.AddEventListener(DOMEventType.OnClick, domEvent, false);
}
};
browser.LoadHTML(@"<!DOCTYPE html>
<html lang='en' xmlns='http://www.w3.org/1999/xhtml'>
<body>
<h1>Hello!!!</h1><br>
<form
id='formTrying'
method='post'
action='http://localhost/MyWebSite/MyMvcView?MyQueryStringParam1=something&Param2=something'
>
<input name='txtSomething' type='text' value='Trying something...'><br>
<input type='submit' value='Submit...'>
</form>
</body>
</html>");
以下文章详细说明了如何注册DOM事件监听器: https://dotnetbrowser.support.teamdev.com/support/solutions/articles/9000110034-listening-to-dom-events
此外,还有一篇文章介绍了如何以编程方式设置表单字段的值:https://dotnetbrowser.support.teamdev.com/support/solutions/articles/9000110038-setting-input-field-value-working-with-form
。示例中的Value
和Checked
属性是与JavaScript中可用的value
和checked
属性相对应的读写属性。
