正则表达式错误匹配

Question

I am trying a regex to validate an Url.

var url = "https://www,google.com";
var urlRegex = /(https|http)?:\/\/(?:\w[\-\w.]+)(?:\/[\-\w+&@#\/%=~_|!:,.;]*)?(?:\?[\-A-Z0-9+&@#\/%=~_|!:,.;]*)?/i;
var result = urlRegex.test(url);

so i am getting "result" as true but i should get false as "url" contains comma. Kindly help.

Answer 1

Add anchors ( ^ for beginning of a string, and $ for the end of the string):

^(https|http)?:\/\/(?:\w[\-\w.]+)(?:\/[\-\w+&@#\/%=~_|!:,.;]*)?(?:\?[\-A-Z0-9+&@#\/%=~_|!:,.;]*)?$
^                                                                                                ^

Answer 2

You are getting true since your regex partly matches.

Use ^(https|http)?:\\/\\/(?:\\w[\\-\\w.]+)(?:\\/[\\-\\w+&@#\\/%=~_|!:,.;]*)?(?:\\?[\\-A-Z0-9+&@#\\/%=~_|!:,.;]*)?$

instead.
