Execute Javascript method from browser address bar - GWT
提问by quarks
I'm trying to execute Javascript on my web application by executing this on the browser URL/address bar:
我正在尝试通过在浏览器 URL/地址栏上执行此操作来在我的 Web 应用程序上执行 Javascript：
javascript:window.alert('test');void(0);
However, nothing happens and the alert box is not showing up? Could the reason be that the app is running in DevMode?
但是，没有任何反应并且没有显示警报框？原因可能是该应用程序在 DevMode 下运行？

I believe most browsers refuse to execute javascript:URLs from the URL bar as a safety measure (there's been messages on the web –esp. Facebook– telling people to copy-paste a javascript:URL to their URL bar that triggered an XSS). They didn't want to break bookmarklets though, so you can put that code in a bookmark; but it's much easier to just open the browser's JS console and type that command there.
我相信大多数浏览器都拒绝javascript:从 URL 栏执行URL 作为安全措施（网络上有消息 - 尤其是 Facebook - 告诉人们将javascript:URL复制粘贴到他们的 URL 栏中，从而触发了 XSS）。不过，他们不想破坏书签，因此您可以将该代码放入书签中；但是打开浏览器的 JS 控制台并在那里输入该命令要容易得多。
Anyway, it's not due to GWT's DevMode.
无论如何，这不是由于 GWT 的 DevMode。

You can write your javascript code inside the block like this
您可以像这样在块内编写 javascript 代码
javascript:{alert("ok");}
