我有一个动态数组arr
的对象产生以下结果:
{value:0, name:'Safety'},{value:0, name:'Environmental'},{value:0, name:'Finance'},{value:0, name:'Health'},{value:1, name:'Quality'}
我想在以下JavaScript中使用它:
series: [
{
name: 'Pie Chart',
type: 'pie',
radius: '55%',
center: ['50%', '60%'],
data: [arr]
//data: [{value:0, name:'Safety'},{value:0, name:'Environmental'},{value:0, name:'Finance'},{value:0, name:'Health'},{value:1, name:'Quality'}]
}
]
然而,当我使用data: [arr]
时,没有显示图表。但是如果我粘贴原始数组输出就可以了。
有什么方法可以解决这个问题吗?
编辑:调试器结果如下:
["{value:0, name:'Safety'}", "{value:0, name:'Environmental'}", "{value:0, name:'Finance'}", 2 more...]
当我alert(arr)
显示时没有双引号。

<script type="text/javascript">
window.onload = function () {
$.ajax({
dataType: "json",
url: "/Home/GetDataPie",
type: "POST",
data: JSON,
success: function (data) {
PieChart(data);
},
error: function () {
alert("err!");
}
});
}
function PieChart(data) {
var arr = [];
var arrayLength = data.value.length;
for (var i = 0; i < arrayLength; i++) {
var item = "{value:" + parseInt(data.value[i]) + ",name:'" + data.name[i] + "'}";
arr.push(item);
}
//shows correct array list
//alert(arr);
var myChart = echarts.init(document.getElementById('main'));
option = {
title: {
text: 'My Chart',
subtext: '',
x: 'center'
},
tooltip: {
trigger: 'item',
formatter: "{a} <br/>{b} : {c} ({d}%)"
},
legend: {
orient: 'vertical',
x: 'left',
data: data.name
},
toolbox: {
show: true,
feature: {
mark: { show: true },
dataView: { show: true, readOnly: true },
magicType: {
show: true,
type: ['pie'],
option: {
funnel: {
x: '25%',
width: '50%',
funnelAlign: 'left',
max: 1548
}
}
},
restore: { show: true },
saveAsImage: { show: true }
}
},
calculable: false,
series: [
{
name: 'Pie Chart',
type: 'pie',
radius: '55%',
center: ['50%', '60%'],
data: arr
}
]
};
myChart.setOption(option);
}
</script>
结果如下:

用户@AshishMalhotra在下面的评论中给出的正确答案
替换
var item = "{value:" + parseInt(data.value[i]) + ",name:'" + data.name[i] + "'}";
与
var item = {value: data.value[i] ,name:data.name[i]};

尝试替换
data: [arr]
与
data: arr
由于arr本身就是一个数组,因此arr = [{值:0,名称:'安全'},{值:0,名称:'环境'},{值:0,名称:'财务'},{值:0,名称:'健康'},{值:1,名称:'质量'}]。
这意味着您的数据属性当前设置为读取[[{值:0,名称:'安全'},{值:0,名称:'环境'},{值:0,名称:'财务' },{value:0,name:'Health'},{value:1,name:'Quality'}]],或带有一个值的数组,即arr。

您好,我希望这会对您有所帮助:
首先尝试构建数据和数据系列:
try building the data for legend and data series first as:
var groupChartData=[];
var groupEmployeeDataSeries=[];
// build from dynamic data (json or array)
<for data: datalist>
groupChartData.push(data.name);
groupEmployeeDataSeries.push({value:data.value,name:data.name+"("+ data.value+")"});
</for>
echartPie.setOption({
tooltip: {
trigger: 'item',
formatter: "{a} <br/>{b} : {c} ({d}%)"
},
legend: {
x: 'center',
y: 'bottom',
data: groupChartData
},
toolbox: {
show: true,
feature: {
magicType: {
show: true,
type: ['pie', 'funnel'],
option: {
funnel: {
x: '25%',
width: '50%',
funnelAlign: 'left',
max: 1548
}
}
},
saveAsImage: {
show: true,
title: "Save Distribution"
}
}
},
calculable: true,
series: [{
name: 'Employee Distribution ('+type+' Wise)',
type: 'pie',
radius: '55%',
center: ['50%', '48%'],
data:groupEmployeeDataSeries
}]
});
这对我有用。
