Question

I need code example for:

• custom JavaScript function that takes a single object as an argument
• uses jquery ajax method to make ajax call
• object argument should specify all possible values that can be customized.
• For example: type of ajax call, data to be passed, success, error handlers etc. etc.
• if any values are not present it should assume defaults

Answer 1

Here is a basic skeleton of the function you are trying to make.

function AJAXCall(obj){
  var type = obj.type || 'GET'; // 'GET' is the default here
  // more variables...
  $.ajax({
    url: 'http://example.com',
    type: type,
    // more options...
  });
}

Then you can call your function like so:

var options = {
  type: 'POST'
  // more options...
};
AJAXCall(options);

Here are the docs for $.ajax, they may help: http://api.jquery.com/jQuery.ajax/
