URL Validation REGEX - URL just valid with http://
提问by Peesen87
How it works
这个怎么运作
I have an input field to enter the URL of a Website and i wanna check it and if the URL is OK i will give the inputfield a class("validated_ok") and remove a class ("cf_required") and if its wrong the other way around.
我有一个输入字段来输入网站的 URL，我想检查它，如果 URL 正常，我会给输入字段一个类（“validated_ok”）并删除一个类（“cf_required”），如果它错了另一个绕道。
Problem

Remove the |www\.?
删除|www\.?
^(http:\/\/www\.|https:\/\/www\.|http:\/\/|https:\/\/)[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?$
回答by DGS
just change your regex to make http(s) required
只需更改您的正则表达式即可使 http(s) 成为必需
/^http(s)?:\/\/(www\.)?[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:[0-9]{1,5})?(\/.*)?$/.test('www.google.com')

(\w*\W*)?\w*(\.(\w)+)+(\W\d+)?(\/\w*(\W*\w)*)*

^http(s?):\/\/(www\.)?(((\w+(([\.\-]{1}([a-z]{2,})+)+)(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*$)|(\w+((\.([a-z]{2,})+)+)(\:[0-9]{1,5}(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*$)))|(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}(([0-9]|([1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5]+)+)(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*)((\:[0-9]{1,5}(\/[a-zA-Z0-9\_\=\?\&\.\#\-\W]*)*$)*))$
In this http is mandatory and it can take port and sub resources also.
e.g http://example.com
https://example.qwerty.com/id
https://example.com:8989
http://example.qwerty.com:8989/id
https://10.1.1.1/id
https://10.1.1.1:9090/id
