# --description--
有時你想爲網站添加一個 `a` 元素,但還不確定要將它鏈接到哪裏。
當你使用 `JavaScript` 更改鏈接的指向時,這也很方便,我們將在後面的課程中介紹。
# --instructions--
`href` 屬性的當前值是指向 “`https://www.freecatphotoapp.com`”。 請將 `href` 屬性的值替換爲`#`,以此來創建鏈接佔位符。
例如: `href="#"`
# --hints--
`a``href` 屬性值應爲 "#"。
```js
assert($('a').attr('href') === '#');
```
