如何在Javascript中将数组转换为对象

Question

I am trying to convert in Javascript an array

A=['"age":"20"','"name":"John"','"email":"john@email.com"'];

to object

O={"age":"20","name":"John","email":"john@email.com"}.

How I can do this. Thanks

Answer 1

Since the keys are quoted, you can take advantage of JSON.parse . You can just make the array a string, wrap it in curly brackets, and parse it.

 var A = ['"age":"20"', '"name":"John"', '"email":"john@email.com"']; var temp = "{" + A.toString() + "}"; var theObj = JSON.parse(temp); console.log(theObj);

Answer 2

Should be straight forward, just iterate and split on the colon

 var A = ['"age":"20"','"name":"John"','"email":"john@email.com"']; var O = {}; A.forEach(function(item) { var parts = item.split(':').map(function(x) { return x.trim().replace(/\\"/g,'') }); O[parts[0]] = parts[1]; }); document.body.innerHTML = '<pre>' + JSON.stringify(O, null, 4) + '</pre>';

Answer 3

Try this:

 const A = ['"age":"20"', '"name":"John"', '"email":"john@email.com"']; const result = A.reduce((res, i) => { let s = i.split(':'); return {...res, [s[0]]: s[1].trim().replace(/\\"/g, '')}; }, {}); console.log(result);
