Hello !
Is it possible to create a variable to extract the content in this way?
document.querySelectorAll('button.pv-top-card-v2-section__link.pv-top-card-v2-section__link-experience span.pv-top-card-v2-section__entity-name')[0].innerText
"TTarga - Carreira e Recolocação"

The querySelectorAll method is supported by Chromium.
Use a JavaScript extension like the one in the JSRTTIExtension demo to get the result in Delphi.

Hello!
Sorry, but I can not.
Could you write a sample application code?
Thank you!

You only need to modify the TJSRTTIExtensionFrm.Chromium1ContextMenuCommand procedure.
Replace the line 226 and set testhtml with the querySelectorAll return value.

Hello !
I did not make it.
Let's say I want to extract the information from this field from the site
"button.pv-top-card-v2-section__link.pv-top-card-v2-section__link-experience span.pv-top-card-v2-section__entity-name"
Should I report this field somewhere?
Thank you very much for your attention.

The TJSRTTIExtensionFrm.Chromium1ContextMenuCommand procedure would have this code when commandId is MINIBROWSER_CONTEXTMENU_JSVISITDOM :
Code: Select all
MINIBROWSER_CONTEXTMENU_JSVISITDOM :
if (browser <> nil) and (browser.MainFrame <> nil) then
browser.MainFrame.ExecuteJavaScript(
'var testhtml = document.querySelectorAll(' + quotedstr('button.pv-top-card-v2-section__link.pv-top-card-v2-section__link-experience span.pv-top-card-v2-section__entity-name') + ')[0].innerText;' +
'myextension.sendresulttobrowser(testhtml, ' + quotedstr(CUSTOMNAME_MESSAGE_NAME) + ');', // This is the call from JavaScript to the extension with DELPHI code in uTestExtension.pas
'about:blank', 0);
Notice that I replaced this line in the original code :
Code: Select all
'var testhtml = document.body.innerHTML;' +

Hello !
Thank you very much, it worked out with the right mouse button.
How could I pass the result straight to an edit?

The TJSRTTIExtensionFrm.Chromium1ProcessMessageReceived procedure saves the text in FText and sends a MINIBROWSER_SHOWTEXTVIEWER message to the form.
TJSRTTIExtensionFrm.ShowTextViewerMsg is executed when the form receives the MINIBROWSER_SHOWTEXTVIEWER message. You only need to set MyEdit.Text := FText; and remove the SimpleTextViewerFrm references from that procedure.

Sorry, but how do you get this result without having to right-click?
I would like to click the button and display the result in the edit. According to the image.
