如何在Form_Load中通过GeckoWebBrowser来控制url并以显示的形式访问DOM? [英] How can I nevigate an url through GeckoWebBrowser within Form_Load and get access the DOM in form shown ?
本文介绍了如何在Form_Load中通过GeckoWebBrowser来控制url并以显示的形式访问DOM?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
请参阅以下代码。
Please see the following code.
private void Form1_Load(object sender, EventArgs e)
{
geckoWebBrowser1.Navigate("http://localhost:62343/ReportPage.html);
}
private void Form1_Shown(object sender, EventArgs e)
{
var item1 = geckoWebBrowser1.Document.GetElementById("DynamicGrid");
htmlelem = item1.InnerHtml;
}
问题是当我运行我的项目时,我在Form1_Shown中将item1设为null。
但是当我把这个代码放在按钮事件中时,例如
The problem is that when I run my project I get item1 as null in Form1_Shown.
But When I put this code under a button event like
private void buttonGetDom_Click(object sender, EventArgs e)
{
var item1 = geckoWebBrowser1.Document.GetElementById("DynamicGrid");
htmlelem = item1.InnerHtml;
}
然后我得到了innerhtml。如何在Form_Shown中获取此元素的innerhtml?
请记住,我只需从Form1_Shown访问此DOM,并且我正在使用GeckoWebBrowser。 />
有人可以帮我吗?
Then I get the innerhtml. How can I Get innerhtml of this Element in Form_Shown ?
Please keep in mind that I need to access this DOM only from from Form1_Shown and I am using GeckoWebBrowser.
Can anyone help me please ?
推荐答案
在控制之前你将无法访问该文件已完成加载页面。
假设您正在使用 GeckoFX [ ^ ]库,您需要等待DocumentCompleted
事件被引发,然后才能访问该文档。
You won't be able to access the document until the control has finished loading the page.
Assuming you're using the control from the GeckoFX[^] library, you need to wait for theDocumentCompleted
event to be raised before you can access the document.
