and I wanted to remove all character after “/” (including “/”).
So that the result will be

www.site.com

NOTE: shot is dynamically changing value
and this will all done on javascript.

Answer 1

Assuming that you want everything before the / you could find the index of the character and return the substring before it:

var shot = "www.site.com/ask";
var index = shot.indexOf("/");
var result;
if (index < 0) {
    result = shot;
} else {
    result = shot.substr(0, index);
}
// result = "www.site.com"

If you would want to get the domain from a string including the protocol e.g. http://www.site.com/ask and get www.site.com then you would need to include additional logic as the code above would return http:.
