For example, I have:
var Data = [
{ id_list: 1, name: 'Nick', token: '312312' },
{ id_list: 2, name: 'John', token: '123123' },
]
Then, I want to sort/reverse this object by name
, for example. And then I want to get something like this:
var Data = [
{ id_list: 2, name: 'John', token: '123123' },
{ id_list: 1, name: 'Nick', token: '312312' },
]
And now I want to know the index of the object with property name='John'
to get the value of the property token.
How do I solve the problem?
Since the sort part is already answered. I'm just going to propose another elegant way to get the indexOf of a property in your array
Your example is:
var Data = [
{id_list:1, name:'Nick',token:'312312'},
{id_list:2,name:'John',token:'123123'}
]
You can do:
var index = Data.map(function(e) { return e.name; }).indexOf('Nick');
Array.prototype.map
is not available on IE7 or IE8. ES5 Compatibility
And here it is with ES6 and arrow syntax, which is even simpler:
const index = Data.map(e => e.name).indexOf('Nick');
