1) Call JS functions in C #

Modify the attributes of webbrowser so that C # can call the js method:

Webbrowser1.objectforscripting = this;

If you want to pass a value, you can define the object [] array.

The specific method is as follows:

First, define the method called by C # In JS:

Function messageaa (Message)

{

Alert (Message );

}

Call the js method messageaa in C #

Private void button#click (Object sender, eventargs E)
{
// Call the MessageBox method of JavaScript and input parameters

Object [] objects = new object [1];

Objects [0] = "C # Diao JavaScript ";

Webbrowser1.document. invokescript ("messageaa", objects );
}

2) Call the C # method in JS

Calling the C # method in JS is relatively simple:

First, define the method called by JS in C:

Public void mymessagebox (string message)
{
MessageBox. Show (Message );
}

Call the C # method in JS:

<! -- Call C # Method -->
<Button onclick = "window. External. mymessagebox ('javascript access C #Code') ">
Javascript access C # Code </button>
