Why is the for loop not working?

Question

JavaScript

There is an ajax request, in success I try to use the for loop, it does not work, that is, it does not go inside it. Foreach works, but I need for.

Answer 1

Show your request code, it will be easier to suggest

Answer 2

If you do something like
this in a loop and response is not an array but an object with properties, then response.length will be undefined and the loop will not be executed.
For example, try doing the following in the console:

var response = {key1: 'property1', key2: 'property2'};
console.log( response.length); // undefined
console.log( Object.keys(response).length); // 2

Answer 3

Maybe you have something similar like this example?
Show the request code.

var bongo = [];
for (i = 0; i < 10; i++)
{

  (function(i)
    {
      $.ajax(
        {
          type: "GET",
          url: "http://localhost",
          data: queryString,
          success: function(request) {bongo[i] = request } 
        });  
    })(i);
}
