|
14
|
+ Usage Note:
|
|
|
15
|
+ -----------
|
|
|
16
|
+ Do not use both ajaxSubmit and ajaxForm on the same form. These
|
|
|
17
|
+ functions are intended to be exclusive. Use ajaxSubmit if you want
|
|
|
18
|
+ to bind your own submit handler to the form. For example,
|
|
|
19
|
+
|
|
|
20
|
+ $(document).ready(function() {
|
|
|
21
|
+ $('#myForm').bind('submit', function(e) {
|
|
|
22
|
+ e.preventDefault(); // <-- important
|
|
|
23
|
+ $(this).ajaxSubmit({
|
|
|
24
|
+ target: '#output'
|
|
|
25
|
+ });
|
|
|
26
|
+ });
|
|
|
27
|
+ });
|
|
|
28
|
+
|
|
|
29
|
+ Use ajaxForm when you want the plugin to manage all the event binding
|
|
|
30
|
+ for you. For example,
|
|
|
31
|
+
|
|
|
32
|
+ $(document).ready(function() {
|
|
|
33
|
+ $('#myForm').ajaxForm({
|
|
|
34
|
+ target: '#output'
|
|
|
35
|
+ });
|
|
|
36
|
+ });
|
|
|
37
|
+
|
|
|
38
|
+ When using ajaxForm, the ajaxSubmit function will be invoked for you
|
|
|
39
|
+ at the appropriate time.

|
|
|
623
|
+ *
|
|
|
624
|
+ * The advantages of using this method instead of ajaxSubmit() are:
|
|
|
625
|
+ *
|
|
|
626
|
+ * 1: This method will include coordinates for <input type="image" /> elements (if the element
|
|
|
627
|
+ * is used to submit the form).
|
|
|
628
|
+ * 2. This method will include the submit element's name/value data (for the element that was
|
|
|
629
|
+ * used to submit the form).
|
|
|
630
|
+ * 3. This method binds the submit() method to the form for you.
|
|
|
631
|
+ *
|
|
|
632
|
+ * The options argument for ajaxForm works exactly as it does for ajaxSubmit. ajaxForm merely
|
|
|
633
|
+ * passes the options argument along after properly binding events for submit elements and
|
|
|
634
|
+ * the form itself.
