javascript - Javascript 全局变量数组

Question

我有一个 src js 文件，其中有这段代码。我需要在脚本中管理 est_bandwidth 数组，但即使我确定创建正确，我也无法在全局范围内看到。为什么？我怎样才能在函数之外看到数组？

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;
}

Answer 1

在函数外部声明est_bandwidth变量以使其全局可用。利用var est_bandwidth;
