Hello,

I'm working on simple webview plugin and implemented few JavaScript callbacks. While I'm running my plugin in test mode (launching plugin in sandbox ide) all works perfect. But after I build plugin and install it to my IntelliJ 2022.3 (not sandbox) via zip file JavaScript callbacks not working. I tried to check are they exists using Dev Tools and don't see any.

Maybe someone know how to fix it?

Thanks!

Hi!

How do you try to catch javascript callbacks?

Is it similar to that problem https://intellij-support.jetbrains.com/hc/en-us/requests/4018866 ?

What I discovered for now. For example, this code working fine in 2022.1. But If I try to run it in 2022.3 it doesn't work anymore.

By "not working" I mean Webview can't find this JS function (for example, "window.isInIntellijCallback")

JBCefJSQuery jsQuery  = JBCefJSQuery.create((JBCefBrowserBase) browser);

jsQuery.addHandler((result) -> {
    System.out.println(result);
    return new JBCefJSQuery.Response("IntelliJ Ide");
});

String injectedJavaScript = "window.isInIntellijCallback = function(param) {"
        + "try {"
        + jsQuery.inject("param")
        + ";"
        + "return true;"
        + "} catch(ex) {alert(ex)}"
        + "}";

browser.getCefBrowser().executeJavaScript(injectedJavaScript, browser.getCefBrowser().getURL(), 0);

Sorry, I had a problem with handling Javascript queries via CefMessageRouterHandler, but from your implementation it looks like they are different issues...
