Question

我已将dc插件添加到我的ember应用中。在我的hbs中我添加了

这里是javascript代码：

var data = [

        {date: "12/27/2012", http_404: 2, http_200: 190, http_302: 100},
        {date: "12/28/2012", http_404: 2, http_200: 10, http_302: 100},
        {date: "12/29/2012", http_404: 1, http_200: 300, http_302: 200},
        {date: "12/30/2012", http_404: 2, http_200: 90, http_302: 0},
        {date: "12/31/2012", http_404: 2, http_200: 90, http_302: 0},
        {date: "01/01/2013", http_404: 2, http_200: 90, http_302: 0},
        {date: "01/02/2013", http_404: 1, http_200: 10, http_302: 1},
        {date: "01/03/2013", http_404: 2, http_200: 90, http_302: 0},
        {date: "01/04/2013", http_404: 2, http_200: 90, http_302: 0},
        {date: "01/05/2013", http_404: 2, http_200: 90, http_302: 0},
        {date: "01/06/2013", http_404: 2, http_200: 200, http_302: 1},
        {date: "01/07/2013", http_404: 1, http_200: 200, http_302: 100}
        ];
var ndx = crossfilter(data);
var parseDate = d3.time.format("%m/%d/%Y").parse;
data.forEach(function(d) {
    d.date = Date.parse(d.date);
    d.total= d.http_404+d.http_200+d.http_302;
});

var dateDim = ndx.dimension(function(d) {return d.date;});
var hits = dateDim.group().reduceSum(function(d) {return d.total;});
var minDate = dateDim.bottom(1)[0].date;
var maxDate = dateDim.top(1)[0].date;

hitslineChart
    .width(500).height(200)
    .dimension(dateDim)
    .group(hits)
    .x(d3.time.scale().domain([minDate,maxDate]))
    .yAxisLabel("Hits per day");

dc.renderAll();

如何在控制器中编写这个javascript代码。？

您应该将上面的代码封装在组件中。

将所有与DOM相关的编码放在组件类中的didInsertElement方法中。
