Accessing a function from other .js file

Hi

If you use CommonJS techniques you will be able to achieve what you are after.

If you use the following simple syntax you can use those functions elsewhere;

newfile.js

function internalonly() {
  // this is not available outisde as it is not in the exports entry below
}
function somefunc() {
}
function someotherfunc() {
}
exports.somefunc = somefunc; //public function
exports.someotherfunc = someotherfunc; //public function

You would then use the require keyword in your code and not the include one;

var Mod = require('/newfile') // do not include the dot js
Mod.somefunc(); // you then call it like this

So your code would look something like this;

db.js

function quizfun() {
    var quizes = db.execute('select * from Quiz');
    while (quiz.isValidRow()) {
        var counter = 0;
        dataArray[counter] = quiz.fieldByName('Quiz_Text');
        quiz.next();
        alert(dataArray[counter]);
        counter++;
    };
    return dataArray;
}
exports.quizfun = quizfun;

You then call it in other file like;

var quiz_db = require('/db');
quiz_db.quizfun();

You can call require('/db'); in as many other parts of your app as you need.

As you not from my first example you add many functions inside a single CommonJS module, so you can group logically similar functions, you can also include private functions that are not exposed externally - good for supporting methods.

Top; keep the CommonJS modules small and specific this really helps you manage your code and your app.
