javascript - 在电话和电子邮件输入框中显示正确的 fa fa 图标

Question

在我的表单中，当内部电子邮件正确时，电子邮件 输入框会显示一个绿色圆圈 x。

我希望它显示一个绿色复选标记圆圈图标，如上面的输入框(名字和姓氏)。
此外，当号码无效时，phone 输入框会显示一个红色圆圈复选标记图标，我希望它显示一个红色圆圈 x 图标。

如果有人知道如何实现这一目标，我们将不胜感激!

电子邮件和电话号码上显示的 fa fa 图标不正确:

您的脚本正在运行...
但您只是不根据验证结果更改 FA 图标。

如果有效，请添加:

 $(this).next("i").removeClass("fa-times-circle-o").addClass("fa-check-circle");

如果错误，请添加:

 $(this).next("i").removeClass("fa-check-circle").addClass("fa-times-circle-o");
