Answer 1

Based completely on @Dementric 's answer, this solution is ready to call with a simple jQuery method, 'ucwords'... Thanks to everyone who contributed here!!!

$.extend({
ucwords : function(str) {
    strVal = '';
    str = str.split(' ');
    for (var chr = 0; chr < str.length; chr++) {
        strVal += str[chr].substring(0, 1).toUpperCase() + str[chr].substring(1, str[chr].length) + ' '
    }
    return strVal
}

});

EXAMPLE: This can be called using the method

var string = "this is a test";
string = $.ucwords(string); // Returns "This Is A Test"
