jQuery - get value from array object

rated 0 times [ 161] [ 1] / answers: 1 / hits: 39322 / 8 Years ago, wed, august 17, 2016, 12:00:00

I have an array of object that looks like this:

var result = [{"id":"1", "price":"20.46"}, {"id":"2", "price":"40.00"}]

Right now I can access it like this:

result[0].price

But what I am trying to do is loop through the array of objects and compare the id to a user inputted id and return the matching value. So the index should be irrelevant.

I tried to loop through the array of objects, but I probably made some mistake and got nothing back.

var userinputid = 1;



result.forEach(function() {

    if (userinputid == result.id) {

        alert(result.price);

    }

);

How to solve this?

Instead of result.id you should use currentElementInLoop.id

var result = [{id:1,price:20.46},{id:2,price:40.00}]

var userinputid = 1;



result.forEach(function(e) {

  if (userinputid == e.id) alert(e.price);

});
