我有一个上传功能,它循环选定的文件并将它们添加到服务器文件系统上.

上传工厂

app.factory('uploadFactory', function ($upload, $q) {

    var uploadFactory = {};

    var image = {
        Models: [],
        Images: [],
        uploadImages: function () {
            var defer = $q.defer();
            for (var i = 0; i < this.Models.length; i++) {
                var $file = this.Models[i].file;
                (function (index) {
                    $upload
                        .upload({
                            url: "/api/upload/",
                            method: "POST",
                            file: $file
                        })
                        .success(function (data, result) {
                            // Add returned file data to model
                            var imageObject = {
                                Path: data.Path,
                                Description: image.Models[index].Description,
                                Photographer: image.Models[index].Photographer
                            };
                            image.Images.push(imageObject);

                            defer.resolve(result);
                        });
                })(i);
            } …

我正在尝试使用以下代码扩展Chart.js中的折线图:

var shotsData = {
  labels: ["Shot 1", "Shot 2", "Shot 3", "Shot 4", "Shot 5"],
  datasets: [{ data: [5, 7, 1, 4, 9] }]
};

var ctx = document.getElementById("shots").getContext("2d");

Chart.types.Line.extend({
    name: "LineAlt",
    initialize: function () {
        this.chart.ctx.beginPath();
        this.chart.ctx.moveTo(0, 15);
        this.chart.ctx.lineTo(159, 274);
        this.chart.ctx.stroke();

        Chart.types.Line.prototype.initialize.apply(this, arguments);
    }
});

new Chart(ctx).LineAlt(shotsData);

这绘制了我的图表,但我也希望图表中有一个自定义行,它写在initialize函数内部,但这似乎不起作用.当我删除该行时,Chart.types.Line.prototype.initialize.apply(this, arguments);将显示自定义行.
