我努力改变文本的颜色，当它被点击但没有成功。 question有一个标签，四个标签options，一个标签correct answer和一个标签explanation。如何在使用jquery点击文本时更改文本的颜色？
我试图当任何option用户点击，那么它应该与correct answer匹配，并更改选项，也就是文本的颜色时，答案是正确的文字颜色应该变成绿色，否则颜色应开启变红。
但是，当我点击任何option它只会变成红色。正确的option应该变成绿色，但它变成了红色。我找不出原因。 看看我的代码。告诉我我错在哪里以及解决方案是什么。

可以请你把你的html代码这里。 –
你首先必须知道答案是否正确。然后改变颜色，这不应该很难。 – Ionut
只选择.correctans不是全部，它显然将它们全部设置为红色。 –
