Javascript:单击更改类和标题

Question

单击数字时应将类别和标题从 not_viewed 更改为 viewed颜色从红色变为绿色。但显然，它不起作用，因为没有发生颜色变化。

HTML

<span title="not_viewed" class="not_viewed" id="1" onclick="javascript:changeclass()">1</span>

Javascript

function changeclass() {var NAME = document.getElementById("1"); NAME.className = "viewed" NAME.title="viewed"
  < /script>
}

CSS

span.viewed{color:green; }
span.not_viewed{color:red;}
span{cursor:pointer;}

Answer 1

删除 < /script>从功能标签。
