not able to get the count the response getting through ajax

I have a form that is used to upload multiple files on click of submit button.

For example i am uploading the following files

student.png

animal.png

pet.png

I am using the following ajax to send the values at the backend (code reference taken from).

$.ajax({
    type:"POST",
    url:this.vpb_settings.vpb_server_url,
    data:dataString,
    cache: false,
    contentType: false,
    processData: false,
    success:function(response)
    {
        console.log(response);
    }
});

When i try to print the response through "console.log()", i get the list of the names of the files that were uploaded, which is one of my requirement. So after using "console.log(response)" i get the output as

student

animal

pet

Now i wish to to calculate the number of names that i get, for this i used this code, "console.log(response.length)" but i got the output as

7
6
3

Whereas i want the response as 3 because there are 3 items in the list

can anyone please tell how this can be done

Looks like you are using one ajax call per file, so of course, each response is the name of one file (a string), not an array, hence

  1. 'student'.length => 7
  2. 'animal'.length => 6
  3. 'pet'.length => 3

If you need the amount of files you could use a global counter, like this:

var counter = 0; //<--needs to be declared somewhere it gets initialized once only
function someFuncContainingTheAjaxCall(){
$.ajax({
    type:"POST",
    url:this.vpb_settings.vpb_server_url,
    data:dataString,
    cache: false,
    contentType: false,
    processData: false,
    success:function(response)
    {
        console.log('Files so far ' + (++counter));
    }
});
}

You can create any variable in outer scope and increase it on success callback. Also you will need to reset it to 0 before do call.
