从浏览器地址栏执行Javascript方法 - GWT [英] Execute Javascript method from browser address bar - GWT

问题描述

  javascript我试图通过在浏览器的URL /地址栏上执行这个命令来执行我的web应用程序中的Javascript： ：window.alert（ '试验'）;无效（0）; 
  

然而，没有任何反应，警报框没有显示出来？原因可能是该应用程序在DevMode中运行？

解决方案

我相信大多数浏览器拒绝执行 javascript：来自URL栏的URL作为一项安全措施（网页上有一些消息 - 脸书 - 告诉用户复制粘贴 javascript：触发XSS的URL栏）。尽管他们不想打破小书签，所以可以将该代码放在书签中;但是打开浏览器的JS控制台并在那里键入该命令会容易得多。

无论如何，这不是由于GWT的DevMode。

I'm trying to execute Javascript on my web application by executing this on the browser URL/address bar:

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?

解决方案

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.

Anyway, it's not due to GWT's DevMode.
