Javascript Regex format

Question

I want to check if the input matches this format:

format: "dd/MM/yyyy"

Of course they would have to me numbers. What is the regex expression, and/or jquery/javascript function that i'd use to make sure this input matches this?

Answer 1

This should do it:

/^[0123]?\d\/[01]?\d\/\d{2,}$/

Remember that only certain numbers are valid months and days.

Other approaches can be found at the Regular Expression Library .

Answer 2

尝试这个：

var matches = str.search(/^\d{2}\/\d{2}\/\d{4}$/) > -1;

Answer 3

如果您只是想检查格式，而不是它实际上是一个有效日期，则以下内容应该有效：

/\d{2}\/\d{2}\/\d{4}/
