Divide a string using JavaScript regular expressions

I have a string like

"Employee Name is Jason Taylo开发者_运维百科r"

I need a regular expression to extract what is in the left hand side of "is"

"Employee Name"

And another to extract what is in the right hand side of "is"

"Jason Taylor"

I have this

function BreakString(string) {      
    return string.replace(/((.+?)(is)).*/, '$1');
}

which returns "Employee Name is"

Can you please help me to solve this?

You missed a backreference:

function BreakString(string) {      
  return string.replace(/(.+?) is (.*)/, '$1 $2'));
}

or without regex

function noIs(str) {
  var parts = str.split(" is ");
  return parts[0] + ":" + parts[1];
}

 ([^.]+) is ([^.]+)

seems to work
