试图迭代数据集

我是javascript的新手,我无法弄清楚如何循环一些代码,以便它基本上创建一个数组,然后我可以传递给我的绘图变量。

我不确定从哪里开始。现在我有一大块代码,它接受我的第一个数据集(dataOne)并对其进行格式化,以便它可以进入我的绘图变量。我基本上需要为其他数据集再做三次 - 希望包含example.getDataSets函数以某种方式循环。

有没有好办法呢?

这是我的代码:

的script.js

var example = {};

example.data = {
    dataOne: {data: [{"date":1333238400000,"data":23},{"date":1333324800000,"data":37},{"date":1333411200000,"data":49},{"date":1333497600000,"data":54},{"date":1333584000000,"data":30},{"date":1333670400000,"data":19},{"date":1333756800000,"data":15},{"date":1333843200000,"data":19},{"date":1333929600000,"data":145}],
    dataTwo: {data: [{"date":1335830400000,"data":63},{"date":1335916800000,"data":77},{"date":1336003200000,"data":66}],
    dataThree: {data: [{"date":1341100800000,"data":24},{"date":1341187200000,"data":50},{"date":1341273600000,"data":43},{"date":1341360000000,"data":39},{"date":1341446400000,"data":56},{"date":1341532800000,"data":66}],
    dataFour: {data: [{"date":1333238400000,"data":71},{"date":1333324800000,"data":46},{"date":1333411200000,"data":66},{"date":1333497600000,"data":73},{"date":1333584000000,"data":105},{"date":1333670400000,"data":84}]}
}

example.getDataSets = function(){
    return ['dataOne', 'dataTwo', 'dataThree', 'dataFour']
}

example.getSeries = function(month){
    return example.data[month]
}

example.processData = function(data){
    var newData = []
    for(var i = 0; i < data.length; i++){
        newData.push([data[i].date, data[i].data])
    };
    return newData;
}

HTML页面中的我的脚本:

$.getScript("script.js")
    .done(function() {

    var b = example.getSeries('dataOne');
    var d = example.processData(b.data);
    // first correct the timestamps - they are recorded as the daily
    // midnights in UTC+0100, but Flot always displays dates in UTC
    // so we have to add one hour to hit the midnights in the plot
    for (var i = 0; i < d.length; ++i)
      d[i][0] += 60 * 60 * 1000;

    var plot = $.plot($("#placeholder"), [d] , options);

非常感谢任何建议!

尝试

var d = example.processData(b);

作为

console.log('b')

也不会记录您的data(在b 变量中),但字符串: - )

答案 1 :(得分:0)

您将字符串文字'b'传递给example.processData而不是存储在变量b中的对象。它应该是

var d = example.processData(b);

同样example.getSeries返回的对象不是数组。该数组位于对象的data属性中。

此外,您的数据中也存在语法错误,在前3个对象的数组末尾缺少]}
