About

Breeze provides a wrapper around fetch function to make requests in jQuery-like API.

View Source Code

Sending request

$.ajax(url|options);
$.ajax(url|options, data|successFn);
$.get(url|options, data|successFn);
$.post(url|options, data|successFn);

Options

Here is a list of available options:

$.ajax({
    url: 'url',
    method: 'get|post|put|delete|head',
    headers: {
        'X-Requested-With': 'XMLHttpRequest'
    },
    data: Object|$('#myform'),
    success: (data, response) => {},
    complete: (response) => {},
    error: (response, error) => {},
});

You can pass other options that are the part of fetch API.

• headers — key-value pairs of the headers to pass in request. Additionally, you can unset default headers using the nulls:

  headers: {
      'X-Requested-With': null
  }
  

• data — object with data to send. You can also pass the form element and Breeze will submit its data automatically.
• success — function to execute after success response was received. First argument of the function is a json object or plain text. The second one is a response object.
• complete — function to execute after response was received.
• error — function to execute after unsuccessful request. First argument is a response object. It may be undefined is request was aborted by client. The second one is an error object.

Aborting request

Ajax function returns a Promise with custom abort method. Use it to abort unfinished request:

var promise = $.get({
    url: 'url',
    error: function (response, error) {
        // response is undefined when request is aborted
        console.log(error);
    }
});

promise.abort();
