如何验证 javascript 中的年份文本框？

Question

I am using a textbox on my page which is used to enter year in yyyy-yyyy format.

Can you tell how can i validate textbox in this format through javascript??

Thanks in advance...

Answer 1

You can match it with a regular expression:

var pattern = /\d{4}-\d{4}/;

Answer 2

If you are not using any javascript library (like jQuery, etc), Javascript Regular Expressions could be used for validating the input.
