Javascript Global Variable array

Question

I have a src js file where I have this code. I need to manage the est_bandwidth array in the script but even if I'm sure of the correct creation I can't see globally. Why? How can I see the array also outside of the function?

var maxBandwidth = 8 * 1024 * 1024;        // 8 Mbps
var est_bandwidth = new Array();
function bandwidth(initial_bps, weight_f, weight_s){

this.bps = initial_bps;
this.weight_f = weight_f;
this.weight_s = weight_s;

}

bandwidth.prototype.calcWeightedBandwidth = function(_bps) {

this.bps = parseInt(((this.weight_f*this.bps) + (this.weight_s * _bps))/2)*0.9;  
    if( this.bps > maxBandwidth && maxBandwidth > 0) this.bps = maxBandwidth;
    est_bandwidth.push(this.bps/1024);
    return this.bps;
}

Where is est_bandwidth declared? I can't see an initialization - I'd expect this to throw an error. — Bergi

I just forgot the initialization in the example, now I've edited the code here but same problem: I see an empty array even if it's not empty. — user1903898

Ah, Ok. And this is the whole js file? How do you access it from outside? — Bergi

I have an html page where I have <script src="bandwidth.js"></script> — user1903898

this bandwidth.js interact with other js and I want to be able to do something like this <script> document.getElementById("elem").innerHTML=est_bandwidth </script> — user1903898

Declare est_bandwidth variable outside of the function to make it available globally. Use var est_bandwidth;

I've declared the variable but nothing changed, I see an empty array

Are you certain that code that is suppose to fill the array with data does actually run? Put an alert just before est_bandwidth.push to confirm that.
