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 - If a textbox is filled in, the code stops there and doesn't continue.

2nd - by the email, it won't check the 2nd if statement, if the first one is true.

I think the 1st and 2nd problem are both the same, that as soon as it sees one thing true, it stops there.

Answer 1

I tried your code on Firefox and IE and added alerts to each function. When clciked on 'Register' button, in Firefox, all the alerts were shown while in IE only firstName alert came up.

Reason:: function xValidate and yValidate was giving error in IE.

at line :: inbox.style.backgroundColor="rgba(255, 0, 0, .1)"; SCRIPT380: Invalid property value.

I would suggest, check your console for any JS error, it should solve your problem.

Hope this helps!
