在与 javascript 分离的单独样式表中对图表和地图进行外部样式设置

Externally styling charts and maps in separate stylesheet detached from javascript

我有一些人力车图表和 Jvector 地图需要在单独的 css 样式表中进行外部样式设置以更改图表的颜色。如果在我的 html 中看不到 svg,我该如何访问已在 js 文件中指定的样式。

/* Rickshaw dashboard chart */
    var seriesData = [ [], [] ];
    var random = new Rickshaw.Fixtures.RandomData(1000);

    for(var i = 0; i < 100; i++) {
        random.addData(seriesData);
    }

    var rdc = new Rickshaw.Graph( {
            element: document.getElementById("dashboard-chart"),
            renderer: 'area',
            width: $("#dashboard-chart").width(),
            height: 250,
            series: [{color: "#B4D278",data: seriesData[0],name: 'New'}, 
                     {color: "#588007",data: seriesData[1],name: 'Returned'}]
    } );

    rdc.render();

    var legend = new Rickshaw.Graph.Legend({graph: rdc, element: document.getElementById('dashboard-legend')});
    var shelving = new Rickshaw.Graph.Behavior.Series.Toggle({graph: rdc,legend: legend});
    var order = new Rickshaw.Graph.Behavior.Series.Order({graph: rdc,legend: legend});
    var highlight = new Rickshaw.Graph.Behavior.Series.Highlight( {graph: rdc,legend: legend} );        

    var rdc_resize = function() {                
            rdc.configure({
                    width: $("#dashboard-chart").width(),
                    height: $("#dashboard-chart").height()
            });
            rdc.render();
    }

    var hoverDetail = new Rickshaw.Graph.HoverDetail({graph: rdc});

    window.addEventListener('resize', rdc_resize);        

    rdc_resize();
    /* END Rickshaw dashboard chart */

Rickshaw 有系列 className 选项。

// script.js
// ...
var rdc = new Rickshaw.Graph( {
        element: document.getElementById("dashboard-chart"),
        renderer: 'area',
        width: $("#dashboard-chart").width(),
        height: 250,
        series: [
          {className:'new',data: seriesData[0],name: 'New'}, 
          {className: "rendered",data: seriesData[1],name: 'Returned'}
        ]
} );
// ...

// style.css
.new {
    fill: #B4D278;
}

.rendered {
    fill: #588007;
}
