Hello.
On my work computer runs fine. On other computers, the click does not work.
Test on Cef 102/97 versions. Windows 10/7

Code: Select all

 codeStr :='var aTags = document.getElementsByTagName("span"); var searchText = "Main menu";var found; for (var i = 0; i < aTags.length; i++){if (aTags[i].textContent == searchText) {found = aTags[i];break;}} found.click();';
 ChromiumWindow1.ChromiumBrowser.Browser.Mainframe.ExecuteJavaScript(codeStr, 'about:blank', 0);

Open the Console tab in the DevTools to see the JavaScript error.

Chromium updates, fixes or deprecates some JavaScript features in every release. The best way to debug these errors is using the console.

Hello.
On console log error: "File chooser dialog can only be shown with a user activation"
Is it possible to activate dialog for open file?

If you own that web page there seems to be workarounds :
https://codedocu.com/File-chooser-dialog-can-only-be-shown-with-a-user-activation?2821

Search "File chooser dialog can only be shown with a user activation" (with quotes) in Google to see more workarounds.

If you don't control the web page then I would use a browser in OSR mode and then simulate mouse movements and clicks.
