You can open the error console, depending on your browser. (Ctrl+Shift+J in Firefox, or F12 in Chrome, for example). Most browsers have the console hidden in their developer tools.
您可以打开错误控制台,具体取决于您的浏览器。(例如,Firefox 中的 Ctrl+Shift+J 或 Chrome 中的 F12)。大多数浏览器将控制台隐藏在其开发人员工具中。

The console.log();

Also, you have a problem with your code.

无效。删除脚本标签中的空格,如下所示:
<script type="text/javascript">
console.log("hello world");
</script>

You can add a chrome extension named "console log viewer" and then you can see the logs even without opening the developer tool
您可以添加名为“控制台日志查看器”的 chrome 扩展,然后即使不打开开发人员工具也可以查看日志

- Search and install an add-on named "firebug"
- before reloading your page open firebug and go to console tab.
You will see your desired result. If you have chrome then its already there. just use it
- 打开火狐

你会看到你想要的结果。如果你有 chrome 那么它已经在那里了。就用它
