JS调用C#代码
HTML代码：
<button onclick="window.external.Test('called from script code')">
call client code from script code
</button>
WPF代码中的C＃代码：
public void Test(String message)
{
MessageBox.Show(message, "client code");
}
WPF和JavaScript之间的通信需要完全信任，因此您需要添加以下代码：
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[ComVisible(true)]
public class MainWindow
{
public void Test(String message)
{
MessageBox.Show(message, "client code");
}
}
也经常这么干
//webbrowser设置一个脚本回调的上下文
mywebbrowser.objectForScription = nwe scriptCallBackContext(); [PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[ComVisible(true)]
public calss scriptCallBackContext
{ public void Test(String message)
{
MessageBox.Show(message, "client code");
}
}
c#调用 JS方法
private void Window_Loaded(object sender, RoutedEventArgs e)
{
string curdir = Directory.GetCurrentDirectory();
webBrowser.Navigate(String.Format("file:///{0}/test.html", curdir));
webBrowser.LoadCompleted += (ss, ee) =>
{
var jsCode = "fillData('data...');";
dynamic doc = webBrowser.Document;
webBrowser.InvokeScript("execScript", new Object[] { jsCode, "JavaScript" });
};
}
myscripts.js：
function fillData(data)
{
//document.getElementById("uname").value = data;
var oVDiv = document.getElementById("uname");
//oVDiv.setAttribute("vaue", data);
oVDiv.value = data; //oVDiv.value = data;
//document.write(data);
}
