Chrome中的ES6符号(ES6 Symbols in Chrome)

我正在谷歌Chrome中尝试新的ES6符号,在Chrome Flags中启用“实验性JavaScript”之后,我可以在我的代码中使用new Symbol()

但是,当我尝试运行以下代码时:

var sym = new Symbol();
var obj = {};
obj[sym] = 'Hello, symbols';

我收到以下错误:

TypeError: Conversion from symbol to string

我的代码出了什么问题?

谢谢!


I'm experimenting with the new ES6 Symbols in Google Chrome, and after enabling "Experimental JavaScript" in Chrome Flags, I can use new Symbol() in my code.

However, when I try to run the following code:

var sym = new Symbol();
var obj = {};
obj[sym] = 'Hello, symbols';

I get the following error:

TypeError: Conversion from symbol to string

What's wrong with my code?

Thanks!

您需要从外部li中删除data-toggle =“tab”。

完成后,您的html应该是这个菜单的样子。

<li class="dropdown">
    <a class="dropdown-toggle" data-toggle="dropdown" data-target="#"  href="#">Youth
       <i class="caret"></i>
    </a>
    <ul class="dropdown-menu" role="menu">
        <li><a href="/Home/Youth">YS2</a></li>
    </ul>
</li>

You need to remove the data-toggle="tab" from the outer li.

Your html should look like this for that menu when you are done.

<li class="dropdown">
    <a class="dropdown-toggle" data-toggle="dropdown" data-target="#"  href="#">Youth
       <i class="caret"></i>
    </a>
    <ul class="dropdown-menu" role="menu">
        <li><a href="/Home/Youth">YS2</a></li>
    </ul>
</li>
