我有一个javascript文件,我在该方法中有一个方法“Test”我喜欢调用c#函数。
c#函数与javascript文件中的文件不在同一个文件中。
它位于.cs文件中。那么如何管理javascript函数能够调用c#函数?
我已在互联网上搜索过,但大多数解决方案都基于aspx和apx.cs文件......
我试过这样的事情:
viewer.js
function Test() {
alert("Hello world-2");
window.external.MethodToCallFromScript();
}
ScriptManager.cs
[ComVisible(true)]
public class ScriptManager
{
public void MethodToCallFromScript()
{
Debug.WriteLine("test");
}
}
但它没有用......
有人能帮助我吗?
谢谢!

为了使其正常工作,您必须设置ObjectForScripting
- WebBrwoser
- 属性。{/ p>
这是一个例子
using System;
using System.Windows.Forms;
using System.Security.Permissions;
[PermissionSet(SecurityAction.Demand, Name="FullTrust")]
[System.Runtime.InteropServices.ComVisibleAttribute(true)]
public class Form1 : Form
{
private WebBrowser webBrowser1 = new WebBrowser();
private Button button1 = new Button();
[STAThread]
public static void Main()
{
Application.EnableVisualStyles();
Application.Run(new Form1());
}
public Form1()
{
button1.Text = "call script code from client code";
button1.Dock = DockStyle.Top;
button1.Click += new EventHandler(button1_Click);
webBrowser1.Dock = DockStyle.Fill;
Controls.Add(webBrowser1);
Controls.Add(button1);
Load += new EventHandler(Form1_Load);
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.AllowWebBrowserDrop = false;
webBrowser1.IsWebBrowserContextMenuEnabled = false;
webBrowser1.WebBrowserShortcutsEnabled = false;
webBrowser1.ObjectForScripting = this;
// Uncomment the following line when you are finished debugging.
//webBrowser1.ScriptErrorsSuppressed = true;
webBrowser1.DocumentText =
"<html><head><script>" +
"function test(message) { alert(message); }" +
"</script></head><body><button " +
"onclick=\"window.external.Test('called from script code')\">" +
"call client code from script code</button>" +
"</body></html>";
}
public void Test(String message)
{
MessageBox.Show(message, "client code");
}
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Document.InvokeScript("test",
new String[] { "called from client code" });
}
}
