正则表达式验证 url 并且不以分号或空格结尾

Question

I have the following regex:

var regex = /https:\/\/company\.zoom\.us\/j\/.*\?pwd=.*/i;

How can I modify this regex to ensure that the url string does not end in a semicolon or space?

https://company.zoom.us/j/xxxxx?pwd=zzzzz //Should pass
https://company.zoom.us/j/xxxxx?pwd=zzzzz  //Should fail (ends in a space after the z)
https://company.zoom.us/j/xxxxx?pwd=zzzzz; //Should fail (ends in a semicolon)
https://company.zoom.us/j/xxxxx?pwd=zzzzz;  //Should fail (ends in a space after the semicolon)

Answer 1

If you don't want to allow whitespaces anywhere and not end with ; then get rid of .* from regex that allows any character.

You may just use:

/^https:\/\/company\.zoom\.us\/j\/\S*\?pwd=[^\s;]*$/

Changes:

• \\S: : matches 0 or more of any non-whitespace character
• [^\\s;]* matches any character that is not a ; and not a whitespace
