在Chart.js中绘制对象

Question

我在数组中有一个对象（已由API返回）。说，

data = [{"A":"40","B":"37","C":"31.5"}]

如何在“label”数组中推送A，B，C，D以及Chart.js中“dataset”数组中的值？

Answer 1

使用Object.keys()和Object.values()

这些功能是不言自明的

＆＃13;

＆＃13;

var data = [{"A":"40","B":"37","C":"31.5"}]

// If you know the property key you want to delete use 
// delete data[0]["A"]

//If you dont know it 
//delete data[0][Object.keys(data[0])[0]]

var labels = Object.keys(data[0]);
var dataset = Object.values(data[0])

console.log("labels: ", labels)

console.log("dataset: ", dataset)
