我试图从会话存储变量中加载饼图高清图中的数据,但我没有得到任何结果。
我想要这个:
$(function () {
Highcharts.chart('container', {
chart: {
type: 'pie',
options3d: {
enabled: true,
alpha: 45
}
},
title: {
text: 'Contents of Highsoft\'s weekly fruit delivery'
},
subtitle: {
text: '3D donut in Highcharts'
},
plotOptions: {
pie: {
innerSize: 100,
depth: 45
}
},
series: [{
name: 'Delivered amount',
data: [
['Bananas', 8],
['Kiwi', 3],
['Mixed nuts', 1],
['Oranges', 6],
['Apples', 8],
['Pears', 4],
['Clementines', 4],
['Reddish (bag)', 1],
['Grapes (bunch)', 1]
]
}]
});
});
我将信息存储在会话变量中,如下所示:
sessionStorage.data = "['Bananas', 9], ['Kiwi', 9]";
然后,我将此变量放在数据字段中:
$(function () {
Highcharts.chart('container', {
chart: {
type: 'pie',
options3d: {
enabled: true,
alpha: 45
}
},
title: {
text: 'Contents of Highsoft\'s weekly fruit delivery'
},
subtitle: {
text: '3D donut in Highcharts'
},
plotOptions: {
pie: {
innerSize: 100,
depth: 45
}
},
series: [{
name: 'Delivered amount',
data: sessionStorage.data
}]
});
});
我做错了什么?
非常感谢!

更改
series : [[{name: 'Delivered amount',data: sessionStorage.data}]
到
series = [[{name: 'Delivered amount',data: sessionStorage.data}]

您将会话数据存储为字符串,然后尝试将Highcharts数据设置为该字符串 - 您应该将其反序列化为javascript数组。
如果您更改sessionStorage.data
的格式,请执行以下操作:
'[["Bananas", 9], ["Kiwi", 9]]'
您可以使用JSON.parse
对其进行反序列化:
series: [{
name: 'Delivered amount',
data: JSON.parse(sessionStorage.data)
}]
