给< a>元素自动对焦 [英] Give <a> element autofocus

问题描述

使用以下代码，我试图在页面加载时为元素提供自动对焦.

With the following code I try to give an a element autofocus when the page is loaded.

<a href="/{{setting}}" id="next" class="button big active">Next vocabulary</a>
<script>
    document.getElementbyId("next").focus();
</script>

虽然这在输入字段上可以正常使用，但不适用于该元素.有人可以解释一下我吗?

Whilst this works fine with input fields it doesn't work with that a element. Can anybody explain me while?

致谢

推荐答案

问题是您键入的getElementById错误，应该是大写的'B'.

The problem is that you typed getElementById wrong, it should be an uppercase 'B'.

<a href="/{{setting}}" id="next" class="button big active">Next vocabulary</a>
<script>
    document.getElementById("next").focus();
</script>

现在应该可以了！
