Executes the JavaScript passed. The JavaScript passed can call a JavaScript function in a WebPageSource control.
Notes
ExecuteJavaScript is also available as a global method. If called as a global method, it tries to determine which control in which it is supposed to run. In general, calling the JavaScript from inside the intended control is preferable.
Example
This code in the Action event of a Button displays an alert using JavaScript:
Me.ExecuteJavaScript("alert('Hello!');")
This code will select the text in a WebTextField (or WebTextArea):
WebTextField1.ExecuteJavascript("document.getElementById('" + _
WebTextField1.ControlID + "_inner').select();")
WebTextField1.ControlID + "_inner').select();")
