How to create dynamic variable with get dynamic data from json

Question

I have dynamic price change table, and I want to change my price list from data json dynamically,

I want to get data.Items.Onelow and data.Items.Onehigh values from json data with dynamic variable; But I have problem; My codes under below.

$.ajax({
            type: 'GET',
            url: "data.json",
            dataType: "json",
            contentType: "application/json",
            cache: false,
            success: function(data) {

            var a = ["One", "Two"];
            a.forEach(function(entry) {


            var entry_data_low = data.Items.entry+low; // HERE Problem
            var entry_data_high = data.Items.entry+high; // HERE Problem




            });




        }
    },2000);

      });
    });

"A problem" being, low and high are undefined, I guess?

You should replace this line from

var entry_data_low = data.Items.entry+low; // HERE Problem
var entry_data_high = data.Items.entry+high; // HERE Problem

to

var entry_data_low = data.Items.entry + "low";
var entry_data_high = data.Items.entry + "high";

considering object property is as data.Items.Onelow and data.Items.Twolow.

Balvant Jat Over a year ago

after using string notation it should not say so. Try this data.Items[entry+"low"]
