Step-by-step guide on adding data to an arraylist using JavaScript

My ajax callback function receives a json object (arraylist parsed into json in another servlet) as a response, and then iterates through it.

Ajax section:

$.ajax({
                     url:'ServiceToFetchDocType',
                     data: {"name":name},
                     type:'post',
                     cache:false,
                     success: function(response){

                         var select = $('#document_subtype');
                         select.find('option').remove();
                         $('<option value="">document_subtype</option>').appendTo(select);
                         $.each(response, function(index, value){
                             //insert the values into an array
                         });
                         callback.apply(select);
                     }                   

                 });

Now, my goal is to store these values into a string array. Any suggestions on how I should proceed?

Answer №1

let newArray = [];
for (let item of response){
  newArray.push(item);
}

An alternative approach is to iterate through the values in the response and push them into a new array. If the values are not already strings, you can convert them by using item.toString() before pushing them.

Perhaps a solution could look like:

    let newArr = [];

     function keyValue(key, value)
     {
        this.key = key;
        this.value = value;
     }

Then in your method:

    let pair = new keyValue(index, val);
    newArr.push(pair);

     }
