How to replace everything with blank after question mark in a string?

Question

I am trying to replace everything with blank after question mark.

Suppose I have a string like below:

var str = "/root/Users?SkillId=201;"

Now I want to replace everything with blank after ?.

Expected output: "/root/Users"

I tried below solution:

var str = "/root/Users?SkillId=201;".replace(/[^? ]/g, "");
console.log(str); // output : ?

str = str.split('?')[0] // though worked but not readable

I don't want to use for loop for this. Isn't there is any better way to do this?

Answer 1

This should help

var str = "/root/Users?SkillId=201;"

str = str.replace(/\?.*$/g,"");
console.log(str);

Answer 2

Another option is to get the substring before the '?':

str = str.substr(0, str.indexOf('?'));

Answer 3

Match the content before ?

var str = "/root/Users?SkillId=201;"
var a = str.match(/(.*)\?/);

console.log(a[1])

Answer 4

Simply use JavaScript function

var str = "/root/Users?SkillId=201;";
var str = str.substring( 0, str.indexOf("?")-1 );
console.log(str);
