    Quick prompt method question

    In order to save a little space I would like to change the three current prompt methods into only one, getting all three numbers together.

    Code:
    var a = prompt("What is the first value? \n", " ");
    var b = prompt("What is the second value? \n", " ");
    var c = prompt("What is the third value? \n", " ");

    Code:
    var vals;
    
    while( ( vals = prompt( "Enter the first, second and third values separated by spaces", " ").replace( /^\s*|\s*$/g, '').split( /\s+/ ) ).length != 3 )
    ;
    
    alert( vals );
    Where used, return should be executed unconditionally and always as the last statement in the function.

    That's my signature, it's not part of the damn post!
