JQuery - How to push specific key and value in array?

By Hardik Savani September 6, 2020 Category : Javascript jQuery

In this example, i will let you know how to push specific key with value as array in jquery array. we can add dynamically push key value pair in jquery array.

As we know if we use push method into an array then you can not specify key for value. it will create automatically 0 1 2 3 etc, but if you want to push both key and value then you can not specify key, but in this example i will show you how to create array with specific key value.

So, here i am going to share simple example, so you can check it:

Example 1:

    var myArray = [
        { "id" : "1", "firstName" : "Hardik", "lastName" : "Savani" }, 
        { "id" : "2", "firstName" : "Vimal", "lastName" : "Kashiyani" }, 
        { "id" : "3", "firstName" : "Harshad", "lastName" : "Pathak" }, 
        { "id" : "4", "firstName" : "Harsukh", "lastName" : "Makawana" }
      ];
   
      var myObj = {};
  
      $.each(myArray, function (i, value) {
          myObj[value.id] = value.firstName;
      });  
   
      console.log(myObj);
    
</script>
   
</body>

      ];
    
      var myObj = [];
   
      $.each(myArray, function (i, value) {

      });
