jQuery-OSDI

The jQuery OSDI plugin implements non-authenticated POST via AJAX against OSDI-compliant API endpoints. It can be used to send in data to OSDI-compliant APIs.

Version 1.2.0

This plugin is free and open source, and licensed under the MIT open source license.

Overview & Requirements

The jQuery OSDI plugin attaches to form DOM markup and processes form input to send to OSDI-compliant APIs via AJAX. It can be used to create frontend forms that submit data over an OSDI-complaint API to a remote server.

The plugin makes use of OSDI’s non-authenticated POST features, so an API key or other type of authentication is not required, making this plugin suitable for frontend implementations.

The plugin expects to POST to one of the OSDI helper endpoints, which can accept non-authenticated POSTs according to the spec. For more information about the OSDI format, see the documentation here.

The jQuery OSDI plugin is called on form tags. It can automatically pick up data from the form tag and underlying inputs, in which case special input names are used, or you can specify exactly the body to use in the form of a function that returns JSON to be POSTed via AJAX. Additional options and AJAX callback handlers can be added as well.

The jQuery OSDI plugin requires jQuery version 1.8 or later.

Downloads & Source

You can download the jQuery OSDI plugin file here. A minimized version is available here.

You can view the source and fork the repository on GitHub here.

Basic Usage & Demo

Include jQuery and the plugin javascript file, then call the jQuery OSDI plugin on a form:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" type="text/javascript"></script> 
<script src="jquery.osdi.js" type="text/javascript"></script>

<script type="text/javascript">
$(document).ready(function() {
	$('form').osdi();
});
</script>

A demo with more examples is available here.

Options

The jQuery OSDI plugin can take various options on initialization. Typically, options can be passed on initialization, or can be passed as functions, which are called when the form is submitted. This is useful if you want to dynamically populate options on submit.

The available options are:

Name	Type	Default	Description
endpoint	string	Your form’s `action` attribute.	The endpoint to POST to. Can optionally take a function that returns a string.
body	JSON object	Created from your form’s inputs. (See below for special naming conventions.)	The JSON that will be POSTed to the endpoint. Should be valid OSDI for the endpoint, typically OSDI helper POST format containing at least a person object. See the OSDI documentation form more information and examples. If not present, a body will be created from your form inputs. Can optionally take a function that returns a JSON object. (See below for more information.)
status	string/boolean	subscribed	The email subscription status the server should be asked to set the person to. Valid options typically are: `"subscribed"`, `"unsubscribed"`, `"bouncing"`, `"spam complaint"`. Use `false` to pass no status, which typically means the person’s current status will be unchanged by the server. Can optionally take a function that returns a string/boolean. (Ignored if `body` is present.)
autoresponse	boolean	true	Whether the receiving server should asked to send an email autoresponse. Can optionally take a function that returns a boolean. (Ignored if `body` is present.)
add_tags	array		An array of tags the server should be asked to add to the person. Can optionally take a function that returns an array. (Ignored if `body` is present.)
immediate	boolean	false	Whether the AJAX POST should be called immediately or rather attached as a submit event to the form, to be called when the form is submitted. Calling immediately is useful when using other plugins that attach to the form submit event, such as validation plugins, where you can immediately call the AJAX POST if the form is valid.
done	function		A function to be executed after a successful AJAX POST. A passthrough for jQuery’s .done callback. Can have the same arguments, `data`, `textStatus`, and `jqXHR`.
fail	function		A function to be executed after a failed AJAX POST. A passthrough for jQuery’s .fail callback. Can have the same arguments, `jqXHR`, `textStatus`, and `errorThrown`.
always	function		A function to be executed after an AJAX POST, no matter success or failure. A passthrough for jQuery’s .always function. Can have the same arguments, `data/jqXHR`, `textStatus`, and `jqXHR/errorThrown`.
ajax_options	JSON object	{ type: “POST”, dataType: ‘json’, contentType: ‘application/json’}	An object to be passed through to jQuery’s `$.ajax()` function. See jQuery’s documentation for available options. Can optionally take a function that returns a JSON object.

Form Input Names

If you omit the body option, the jQuery OSDI plugin will attempt to create an OSDI-compliant JSON body to POST for you, using the inputs in your form. Specifically, it will create an inline person object to use as part of the OSDI helper format. Use these special names on your form inputs to tell the plugin which input corresponds to which piece of data:
