Running JavaScript code on a fully loaded website

Is there a way to execute a Javascript function on a website using a Windows Form Application web browser? I'm trying to replicate the functionality of calling Javascript in Chrome's developer console.

Answer №1

Below is the provided solution:

        WebBrowser browser = new WebBrowser;
        browser.Navigate( ... link or Uri ...)

        object[] arguments = new object[1];
        arguments[0] = 12';
        browser.Document.InvokeScript("functionName", arguments);

InvokeScript is used to execute javascript functions. If you have a javascript function like function check(value){...}, then your functionName will be "check" and arguments array will hold value. If there are more parameters, you can fill the args array accordingly. The code snippet above executes the javascript function as functionName(12);

To access an element in the document, use this code:

browser.Document.GetElementById("ControlId") .InnerText = "Bla bla" .InvokeMember("click")
