javascript - jqPlot 饼图无法正确渲染

Question

我在phonegap中使用jqPlot，但存在一些问题，比如如果我为饼图提供静态值，那么它工作得很好，但如果我给出了动态值，然后没有正确渲染

静态图表:-

$.jqplot('chartdiv', [ [ [ 'Cricket', 42],
            [ 'Football', 8 ],
            [ 'Basketball', 4 ], [ 'Chess', 28 ],
            [ ' TableTennis', 18 ] ] ], {
        seriesDefaults : {
            renderer : $.jqplot.PieRenderer,
            rendererOptions : {
                showDataLabels : true
            }
        },
        legend : {
            show : true,
            location : 'e'
        }
    });

O/P:-

动态图表:-

var cricketPortion = document.getElementById("value_1").value;
var footballPortion = document.getElementById("value_2").value;
var basketballPortion = document.getElementById("value_3").value;
var chessPortion = document.getElementById("value_4").value;
var ttPortion = document.getElementById("value_5").value;
$.jqplot('chartdiv', [ [ [ 'Cricket', cricketPortion ],
            [ 'Football', footballPortion ],
            [ 'Basketball', basketballPortion ], [ 'Chess', chessPortion ],
            [ ' TableTennis', ttPortion ] ] ], {
        seriesDefaults : {
            renderer : $.jqplot.PieRenderer,
            rendererOptions : {
                showDataLabels : true
            }
        },
        legend : {
            show : true,
            location : 'e'
        }
    });

O/P:-

告诉我如何摆脱这个..??

Answer 1

尝试一下你就会得到结果

对每个值使用parseInt

parseInt(document.getElementById("value_1").value)
