Attempting to run Javascript in my web application by entering the following in the browser URL/address bar:
javascript:window.alert('test');void(0);
Despite this, the alert box fails to display. Is it possible that the application is in DevMode?
If you want to include your JavaScript code within a block, you can do it in the following way
javascript:{console.log("Hello World");}
Most modern browsers have a security feature that prevents the execution of javascript: URLs directly from the address bar. This measure is in place to protect users from XSS attacks, with many platforms like Facebook warning users not to paste javascript: URLs directly into the address bar. If you need to run JavaScript code, it is recommended to use the browser's console instead of trying to execute it from the URL bar.
It's important to note that this behavior is not related to GWT's DevMode.
