在Visual Studio 2005 for Windows Server 2012中进行开发(Developing in Visual Studio 2005 for Windows Server 2012)

 这应该工作 
 
 
 
 
 
  
function reverse(s){
    return s.split("").reverse().join("");
}
function getMatch(str){
	const regex = /\/+\:(?!s{0,1}ptth)/g;
	const subst = ``;
	const result = reverse(reverse(str).replace(regex, subst));
	console.log(result);
}


getMatch(`Hello could you please visit my website at http://www.example.com or https://www.example.com :/ ://`);
 
 
 
 
 
 由于Javascript不支持负面后观，但确实支持负前瞻，我们通过反转字符串，替换然后再次反转来利用这一优势

This should work
 
 
 
 
 
  
function reverse(s){
    return s.split("").reverse().join("");
}
function getMatch(str){
	const regex = /\/+\:(?!s{0,1}ptth)/g;
	const subst = ``;
	const result = reverse(reverse(str).replace(regex, subst));
	console.log(result);
}


getMatch(`Hello could you please visit my website at http://www.example.com or https://www.example.com :/ ://`);
 
 
 
 
 
Since Javascript does not support negative lookbehind, but does support negative lookaheads, we use this to our advantage by reversing the string, replacing and then reversing again
