Javascript验证无法正常工作-只要if语句为真，它就会停止所有if语句？

Question

1st-如果填写了文本框，则代码将在此处停止，并且不会继续。

第二个-通过电子邮件，如果第一个为true，则不会检查第二个if语句。

我认为第一个问题和第二个问题都是相同的，只要看到一件事情是对的，就立即停止。

Answer 1

我在Firefox和IE上尝试了您的代码，并向每个功能添加了警报。 当单击“注册”按钮时，在Firefox中，将显示所有警报，而在IE中，只会显示firstName警报。

原因：： xValidate和yValidate函数在IE中给出错误。

在行:: inbox.style.backgroundColor="rgba(255, 0, 0, .1)"; SCRIPT380：无效的属性值。

我建议，检查您的控制台是否有JS错误，它应该可以解决您的问题。

希望这可以帮助！
