jsstring类型转换成数组对象类型---eval
js string类型转换成数组对象类型
eval
该⽅法只接受原始字符串作为参数，如果 string 参数不是原始字符串，那么该⽅法将不作任何改变地返回。因此请不要为 eval() 函数传递 String 对象来作为参数。
插件原始数据
/*const data = [
{ time: "00:00", value: 80 },
{ time: '06:00', value: 70 },
{ time: '12:00', value: 120 },
{ time: '18:00', value: 90 },
{ time: '24:00', value: 168 }
];*/
后台的数据
const trainingData = () => {
return builder([{
'training': {
'xaxis': ['00:00', '06:00', '12:00', '18:00', '24:00'],
'data': [0, 30, 45, 60, 30]
}
}])
}
