Jquery Array Object - How To Add Suffix Variable To Index Names

I have this array object which initiates each index: var example = { 'hours': 0, 'overtime': 0, 'income': 0, 'expenditure': 0 }; However it is inside a .each() loop. Each index ne

Solution 1:

Here's an alternate way to do this that might work for you:

var employee = [];

var numEmpl = 100; // total number of employeesfor(var i = 0; i < numEmpl; i++)
  employee[i] = {'hours' : 0, 'overtime' : 0, 'income' : 0, 'expenditure' : 0};

 

The above code gives you an array of objects, one for each employee. Each object (employee) property can be accessed individually like this:

employee[20].overtime = 10;

console.log(employee[20].overtime) // => 10

 

Alternately, you can update all info for a given employee at one time like this:

employee[30] = {'hours' : 45, 'overtime' : 5, 'income' : 1000, 'expenditure' : 0}

console.log(employee[30].overtime) // => 5

 

To add a new employee, simply do this:

employee.push({'hours' : 0, 'overtime' : 0, 'income' : 0, 'expenditure' : 0})

Solution 2:

Add new keys and delete old keys

var example = {
       'hours': 0,
       'overtime': 0,
       'income': 0,
       'expenditure': 0
   };
   var index = 0;
   for (var key in example) {
       example[key + index] = example[key];//adding new key with old valuedelete example[key];//delete old key
   }
   console.log(example);

Output:Object {hours0: 0, overtime0: 0, income0: 0, expenditure0: 0}

Gerald's answer definitely is the best way to do it.

However note that it is also possible to evaluate string expressions as object fields inline. Here's how you do it:

let a = { ['foo' + 'bar' + 123]: 5 }
// a is now { foobar123: 5 }
