【问题描述】:
有一个名为“test.html”的 HTML 文件和两个链接。这个 HTML 文件在geckoWebBrowser1 中显示如下:
<!DOCTYPE html>
<html>
<head lang="tr">
<meta charset="UTF-8">
<title>Test HTML</title>
</head>
<body>
<p><a href="#" id="open_file" class="open-file button" onclick="openFile()">Open A PDF file...</a></p>
<p><a href="#" id="go_to_articles" class="go-to-articles button" onclick="goToArticles()">Go to articles...</a></p>
</body>
<script>
function openFile()
{
// What should I write here?
}
function goToArticles()
{
// What should I write here?
}
</script>
</html>
这里是winforms的内容:
using System;
using System.Windows.Forms;
using Gecko;
namespace Test
{
public partial class Frm1 : Form
{
public Frm1()
{
InitializeComponent();
Xpcom.Initialize("Firefox64");
}
private void Frm1_Load(object sender, EventArgs e)
{
FormBorderStyle = FormBorderStyle.None;
geckoWebBrowser1.Navigate("start\\test.html");
}
public void OpenPDFFile()
{
var ofd = new OpenFileDialog { Filter = @"PDF |*.pdf", Title = @"Select a PDF file..." };
if (ofd.ShowDialog() == DialogResult.OK)
{
// Here, action will be taken regarding the selected file.
}
}
}
}
当我点击 HTML 文件中的Open A PDF file ... 链接时,必须在 Winforms 中触发OpenPDFFile 方法并从对话框中选择 PDF 文件,但我无法这样做。然而,我想通过单击 HTML 文件中的 Go to articles ... 链接来查看位于 Winforms 中的“FrmArticles”表单,但到目前为止我还没有实现。
