如何在JavaScript中创建多维数组

Question

In my project i am using highcart for that i should give the input in below format.

Here is my sample data:

[{"A",23},{"B",24},{"C",25},{"D",26},{"E",27}]

I have to convert the above json array to below format.

data=[["A",23],["B",24],["C",25],["D",26],["E",27]]

How to iterate my sample data and convert the above format. Any help will be greatly appreciated!!!

Answer 1

As your JSON format is wrong, you cannot use JSON.parse on it directly. However, you can use regex to get the data in the intended format.

Steps

1. Replace all { by [ and } by ] , you'll get the string that looks like nested arrays
2. Convert the string to JSON using JSON.parse() to get the array from string

 var arr = '[{"A",23},{"B",24},{"C",25},{"D",26},{"E",27}]'; arr = JSON.parse(arr.replace(/\\{/g, '[').replace(/\\}/g, ']')); console.log(arr); console.log(arr[0][1]); // 23 

Answer 2

[{"A",23},{"B",24},{"C",25},{"D",26},{"E",27}] is wrong,
it should be like [{"A":23},{"B":24},{"C":25},{"D":26},{"E":27}];

 var data = [{"A":23},{"B":24},{"C":25},{"D":26},{"E":27}]; var newData = []; data.forEach(function(val,index){ var keys = Object.keys(val); keys.push(val[keys]); newData.push(keys); }); alert(JSON.stringify(newData));
