camelCase.js

Wrote a function to CamelCase a string in JavaScript. Because, AFAIK, CamelCasing applies only to programming, the function makes sure the string conforms to a legal variable name standard, removing all illegal characters, as well as making sure the string starts with a letter (not a number or an underscore.)

You can add the function to the String object prototype:

String.prototype.toCamelCase = function() {
    // remove all characters that should not be in a variable name
    // as well underscores an numbers from the beginning of the string
    var s = this.replace(/([^a-zA-Z0-9_\- ])|^[_0-9]+/g, "").trim().toLowerCase();
    // uppercase letters preceeded by a hyphen or a space
    s = s.replace(/([ -]+)([a-zA-Z0-9])/g, function(a,b,c) {
        return c.toUpperCase();
    });
    // uppercase letters following numbers
    s = s.replace(/([0-9]+)([a-zA-Z])/g, function(a,b,c) {
        return b + c.toUpperCase();
    });
    return s;
}​ 

Or use it as a stand-alone function:

function toCamelCase(s) {
    // remove all characters that should not be in a variable name
    // as well underscores an numbers from the beginning of the string
    s = s.replace(/([^a-zA-Z0-9_\- ])|^[_0-9]+/g, "").trim().toLowerCase();
    // uppercase letters preceeded by a hyphen or a space
    s = s.replace(/([ -]+)([a-zA-Z0-9])/g, function(a,b,c) {
        return c.toUpperCase();
    });
    // uppercase letters following numbers
    s = s.replace(/([0-9]+)([a-zA-Z])/g, function(a,b,c) {
        return b + c.toUpperCase();
    });
    return s;
