You can use the Array.prototype.filter function which takes a callback and filters accordingly. Per the documentation:

The filter() method creates a new array with all elements that pass the test implemented by the provided function.

The callback, which is the provided function, takes three arguments. From the documentation:

callback

Function is a predicate, to test each element of the array. Return true to keep the element, false otherwise, taking three arguments:

element

The current element being processed in the array.

index

The index of the current element being processed in the array.

array

The array filter was called upon.

We may use element to check the current element and test if it should be filtered or not, like so:

var data = [

  {email: [email protected],nama:User A, Level:Super Admin},

  {email: [email protected],nama:User B, Level:Super Admin},

  {email: [email protected],nama:User C, Level:Standart},

  {email: [email protected],nama:User D, Level:Standart},

  {email: [email protected],nama:User E, Level:Admin},

  {email: [email protected],nama:User F, Level:Standart}

];

var filter = Level;

var keyword = Standart;



var filteredData = data.filter(function(obj) {

	return obj[filter] === keyword;

});



console.log(filteredData);

Here, we use a callback (the test) that checks if the current element (obj)'s property specified in filter is strictly equal to keyword. If it passes, it is kept, and thus all objects with property Level with vale Standart are kept. You can also shorten this with ES6 arrow functions:

var filteredData = data.filter((obj) => obj[filter] === keyword);

This is just shorthand for the above. It is effectively the same, returning true or false based on if the current element's Level property is strictly equal to keyword.
