正则表达式：HTML表单验证中的是否/其他条件
[英]Regex: If/Else Condition in HTML Form Validation
问题描述
I'm struggling with creating an If/Else statement in regex to a) validate a phone number format, then b) invalidate a certain set of phone numbers. 
我正努力在正则表达式中创建If / Else语句，以便a）验证电话号码格式，然后b）使一组特定的电话号码无效。
I currently have: 我目前有：
<input type="tel" name="mobilePhone" pattern="^(?:\+?61|0)4 ?(?:(?:[01] ?[0-9]|2 ?[0-57-9]|3 ?[1-9]|4 ?[7-9]|5 ?[018]) ?[0-9]|3 ?0 ?[0-5])(?: ?[0-9]){5}$">
as a way of targeting the following phone number formats (mobile numbers in Australia): 作为定位以下电话号码格式（澳大利亚的手机号码）的一种方式：
0414570776 0414 570 776 0414570776 0414 570 776 0414570776
However we have a lot of 0411 111 111 or 0400000000 user entries that I would like to try and wash out before submission, but I can't seem to get it right. 但是，我们有很多0411 111 111或0400000000用户条目，我希望在提交之前先尝试将其清除，但我似乎无法正确理解。
I want to invalidate a series of numbers, but for this example, these two would suffice: 0411 111 111 or 0400000000 . 我想使一系列数字无效，但对于此示例，这两个就足够了： 0411 111 111或0400000000 。
Any help would be greatly appreciated. 任何帮助将不胜感激。
Thank you 谢谢
