如何在打字稿中对json对象进行排序

Question

I want to sort a json object in my angular application.

this json object looks like this:

{"9 - ABCDEF":{"isSucceeded":true},
"18 - Remote Software Update":{"isSucceeded":true,},
"4 - n.a."{"isSucceeded":true,}}

I just sort this json object like this:

{"4 - ABCDEF":{"isSucceeded":true},
"9 - Remote Software Update":{"isSucceeded":true,},
"18 - n.a."{"isSucceeded":true,}}

Does anybody know some solutions? I have heard with underscore.js Can anybody give me some examples?

Answer 1

Try something like that:

Using forEach :

 const object = { "18 - na": {"isSucceeded":true,}, "4 - ABCDEF": {"isSucceeded":true}, "9 - Remote Software Update": {"isSucceeded":true,}, }; const ordered = {}; const firstNumber = str => parseInt(str.split(' -')[0].trim()); Object.keys(object).sort((a, b) => firstNumber(a) > firstNumber(b)? 1: -1).forEach(function(key) { ordered[key] = object[key]; }); console.log(ordered);

using the reduce function:

 const object = { "18 - na": {"isSucceeded":true,}, "4 - ABCDEF": {"isSucceeded":true}, "9 - Remote Software Update": {"isSucceeded":true,}, }; const firstNumber = str => parseInt(str.split(' -')[0].trim()); const ordered = Object.keys(object).sort((a, b) => firstNumber(a) > firstNumber(b)? 1: -1).reduce((acc, key) => { acc[key] = object[key]; return acc; }, {}); console.log(ordered);
