webview.executeJavascript is not a function

Question

While starting to sort my js files in a recent Electron project I stopped being able to webview.executeJavascript webview being a variable that is a querySelector on my webview.

I tried testing to see if it getting the webview from the DOM and it is, all I did was move the code that worked perfectly into a module and now executeJavascript Is no longer a function.

If anybody knows the reason or has a clue whats wrong that'd be helpful!

Is it possible you could include the code of your module and if possible the code before it stopped working? — Peter Warrington

I somehow missed the fact that you can't use webview.executeJavascript() the second the Javascript has loaded and needs to wait a bit... It works now.

Maybe the webview was not enabled?

By default the webview tag is disabled in Electron >= 5. You need to enable the tag by setting the webviewTag webPreferences option when constructing your BrowserWindow.

const w = new BrowserWindow({
  webPreferences: {
    webviewTag: true
  }
})
