|
14 * ajaxSubmit() provides a mechanism for submitting an HTML form using AJAX.
|
|
bos@574
|
15 *
|
|
bos@574
|
16 * ajaxSubmit accepts a single argument which can be either a success callback function
|
|
bos@574
|
17 * or an options Object. If a function is provided it will be invoked upon successful
|
|
bos@574
|
18 * completion of the submit and will be passed the response from the server.
|
|
bos@574
|
19 * If an options Object is provided, the following attributes are supported:
|
|
bos@574
|
20 *
|
|
bos@574
|
21 * target: Identifies the element(s) in the page to be updated with the server response.
|
|
bos@574
|
22 * This value may be specified as a jQuery selection string, a jQuery object,
|
|
bos@574
|
23 * or a DOM element.
|
|
bos@574
|
24 * default value: null
|
|
bos@574
|
25 *
|
|
bos@574
|
26 * url: URL to which the form data will be submitted.
|
|
bos@574
|
27 * default value: value of form's 'action' attribute
|
|
bos@574
|
28 *
|
|
bos@574
|
29 * type: The method in which the form data should be submitted, 'GET' or 'POST'.
|
|
bos@574
|
30 * default value: value of form's 'method' attribute (or 'GET' if none found)
|
|
bos@574
|
31 *
|
|
bos@574
|
32 * data: Additional data to add to the request, specified as key/value pairs (see $.ajax).
|
|
bos@574
|
33 *
|
|
bos@574
|
34 * beforeSubmit: Callback method to be invoked before the form is submitted.
|
|
bos@574
|
35 * default value: null
|
|
bos@574
|
36 *
|
|
bos@574
|
37 * success: Callback method to be invoked after the form has been successfully submitted
|
|
bos@574
|
38 * and the response has been returned from the server
|
|
bos@574
|
39 * default value: null
|
|
bos@574
|
40 *
|
|
bos@574
|
41 * dataType: Expected dataType of the response. One of: null, 'xml', 'script', or 'json'
|
|
bos@574
|
42 * default value: null
|
|
bos@574
|
43 *
|
|
bos@574
|
44 * semantic: Boolean flag indicating whether data must be submitted in semantic order (slower).
|
|
bos@574
|
45 * default value: false
|
|
bos@574
|
46 *
|
|
bos@574
|
47 * resetForm: Boolean flag indicating whether the form should be reset if the submit is successful
|
|
bos@574
|
48 *
|
|
bos@574
|
49 * clearForm: Boolean flag indicating whether the form should be cleared if the submit is successful
|
|
bos@574
|
50 *
|
|
bos@574
|
51 *
|
|
bos@574
|
52 * The 'beforeSubmit' callback can be provided as a hook for running pre-submit logic or for
|
|
bos@574
|
53 * validating the form data. If the 'beforeSubmit' callback returns false then the form will
|
|
bos@574
|
54 * not be submitted. The 'beforeSubmit' callback is invoked with three arguments: the form data
|
|
bos@574
|
55 * in array format, the jQuery object, and the options object passed into ajaxSubmit.
|
|
bos@574
|
56 * The form data array takes the following form:
|
|
bos@574
|
57 *
|
|
bos@574
|
58 * [ { name: 'username', value: 'jresig' }, { name: 'password', value: 'secret' } ]
|
|
bos@574
|
59 *
|
|
bos@574
|
60 * If a 'success' callback method is provided it is invoked after the response has been returned
|
|
bos@574
|
61 * from the server. It is passed the responseText or responseXML value (depending on dataType).
|
|
bos@574
|
62 * See jQuery.ajax for further details.
|
|
bos@574
|
63 *
|
|
bos@574
|
64 *
|
|
bos@574
|
65 * The dataType option provides a means for specifying how the server response should be handled.
|
|
bos@574
|
66 * This maps directly to the jQuery.httpData method. The following values are supported:
|
|
bos@574
|
67 *
|
|
bos@574
|
68 * 'xml': if dataType == 'xml' the server response is treated as XML and the 'success'
|
|
bos@574
|
69 * callback method, if specified, will be passed the responseXML value
|
|
bos@574
|
70 * 'json': if dataType == 'json' the server response will be evaluted and passed to
|
|
bos@574
|
71 * the 'success' callback, if specified
|
|
bos@574
|
72 * 'script': if dataType == 'script' the server response is evaluated in the global context
|
|
bos@574
|
73 *
|
|
bos@574
|
74 *
|
|
bos@574
|
75 * Note that it does not make sense to use both the 'target' and 'dataType' options. If both
|
|
bos@574
|
76 * are provided the target will be ignored.
|
|
bos@574
|
77 *
|
|
bos@574
|
78 * The semantic argument can be used to force form serialization in semantic order.
|
|
bos@574
|
79 * This is normally true anyway, unless the form contains input elements of type='image'.
|
|
bos@574
|
80 * If your form must be submitted with name/value pairs in semantic order and your form
|
|
bos@574
|
81 * contains an input of type='image" then pass true for this arg, otherwise pass false
|
|
bos@574
|
82 * (or nothing) to avoid the overhead for this logic.
|

|
83 *
|
|
bos@574
|
84 *
|
|
bos@574
|
85 * When used on its own, ajaxSubmit() is typically bound to a form's submit event like this:
|
|
bos@574
|
86 *
|
|
bos@574
|
87 * $("#form-id").submit(function() {
|
|
bos@574
|
88 * $(this).ajaxSubmit(options);
|
|
bos@574
|
89 * return false; // cancel conventional submit
|
|
bos@574
|
90 * });
|
|
bos@574
|
91 *
|
|
bos@574
|
92 * When using ajaxForm(), however, this is done for you.
|
|
bos@574
|
93 *
|
|
bos@574
|
94 * @example
|
|
bos@574
|
95 * $('#myForm').ajaxSubmit(function(data) {
|
|
bos@574
|
96 * alert('Form submit succeeded! Server returned: ' + data);
|

bos@574

|

bos@574
|
375 * ajaxForm() provides a mechanism for fully automating form submission.
|
|
bos@574
|
376 *
|
|
bos@574
|
377 * The advantages of using this method instead of ajaxSubmit() are:
|
|
bos@574
|
378 *
|
|
bos@574
|
379 * 1: This method will include coordinates for <input type="image" /> elements (if the element
|
|
bos@574
|
380 * is used to submit the form).
|
|
bos@574
|
381 * 2. This method will include the submit element's name/value data (for the element that was
|
|
bos@574
|
382 * used to submit the form).
|
|
bos@574
|
383 * 3. This method binds the submit() method to the form for you.
|
|
bos@574
|
384 *
|
|
bos@574
|
385 * Note that for accurate x/y coordinates of image submit elements in all browsers
|
|
bos@574
|
386 * you need to also use the "dimensions" plugin (this method will auto-detect its presence).
|
|
bos@574
|
387 *
|
|
bos@574
|
388 * The options argument for ajaxForm works exactly as it does for ajaxSubmit. ajaxForm merely
|
|
bos@574
|
389 * passes the options argument along after properly binding events for submit elements and
|
|
bos@574
|
390 * the form itself. See ajaxSubmit for a full description of the options argument.
|
|
bos@574
|
391 *
|
|
bos@574
|
392 *
|
|
bos@574
|
393 * @example
|
|
bos@574
|
394 * var options = {
|
|
bos@574
|
395 * target: '#myTargetDiv'
|
|
bos@574
|
396 * };
|
|
bos@574
|
397 * $('#myForm').ajaxSForm(options);
|
|
bos@574
|
398 * @desc Bind form's submit event so that 'myTargetDiv' is updated with the server response
|
|
bos@574
|
399 * when the form is submitted.
|
|
bos@574
|
400 *
|
|
bos@574
|
401 *
|
|
bos@574
|
402 * @example
|
|
bos@574
|
403 * var options = {
|
|
bos@574
|
404 * success: function(responseText) {
|
|
bos@574
|
405 * alert(responseText);
|
|
bos@574
|
406 * }
|
|
bos@574
|
407 * };
|
|
bos@574

408 * $('#myForm').ajaxSubmit(options);
|
