多个电话号码匹配的HTML正则表达式不起作用

Question

I need to validate two types of phone number formats with in one input. The patterns are,

+XX XXX XX XX XX or

+XX X XXX XX XX

so I use the following pattern

<input type="tel" name="phone" id="phone" class="input" pattern="^\+\d{2} \d{1,3} \d{2,3} \d{2} \d{2}$" required />

but it validates some other patterns like +xx xx xx xx xx

I need to know how to use HTML RegEx exactly for the above mentioned patterns. Thanks in advance

Answer 1

Use | for or operation

This will work

^\+\d{2} (\d{1} \d{3}|\d{3} \d{2}) \d{2} \d{2}$

Answer 2

您需要使[：space：]对regexp可见

^\+\d{2}\ (\d{1,3}\ )+(\d{2}\ ?)$
