Disable click in popup

[Karthik Vishwanath]

Dear Dmitry:

I have a scenario where all the links, buttons etc on a pop-up (cefwindow) must be disabled/inactive.

Please help me out.

Regards,
Karthik

Either use a separate instance of CefClient with a different CefRequestHandler that overrides the OnBeforeBrowse method and return true, or inject some JavaScript into the popup that adds an event listener to the click event of all links and buttons and just cancel it.

I can't give you an example on how to do it directly in CEF, because I do not currently have an environment were I could test it, but here is some JavaScript that will disable all click actions on anchors and buttons:

document.body.addEventListener('click', function(e) {
	if (['A', 'BUTTON'].indexOf(e.target.tagName) !== -1) {
		e.preventDefault();
		e.stopPropagation();
	}
}, true);

This is a very simple way to do it, but there are edge cases were it doesn't work. For example if the anchor contains another element which is actually the one being clicked.
If you actually want to disable all buttons visually, you can do it like that:

Array.prototype.forEach.call(document.querySelectorAll('button'), function(x) {
	x.disabled = true;
});

Links can't be visually disabled without using CSS though.
