- Usage Note:\r
- -----------\r
- Do not use both ajaxSubmit and ajaxForm on the same form. These\r
- functions are intended to be exclusive. Use ajaxSubmit if you want\r
- to bind your own submit handler to the form. For example,\r
-\r
- $(document).ready(function() {\r
- $('#myForm').bind('submit', function() {\r
- $(this).ajaxSubmit({\r
- target: '#output'\r
- });\r
- return false; // <-- important!\r
- });\r
- });\r
-\r
- Use ajaxForm when you want the plugin to manage all the event binding\r
- for you. For example,\r
-\r
- $(document).ready(function() {\r
- $('#myForm').ajaxForm({\r
- target: '#output'\r
- });\r
- });\r
-\r
- When using ajaxForm, the ajaxSubmit function will be invoked for you\r
- at the appropriate time.\r

+ Usage Note:
+ -----------
+ Do not use both ajaxSubmit and ajaxForm on the same form. These
+ functions are intended to be exclusive. Use ajaxSubmit if you want
+ to bind your own submit handler to the form. For example,
+
+ $(document).ready(function() {
+ $('#myForm').bind('submit', function(e) {
+ e.preventDefault(); // <-- important
+ $(this).ajaxSubmit({
+ target: '#output'
+ });
+ });
+ });
+
+ Use ajaxForm when you want the plugin to manage all the event binding
+ for you. For example,
+
+ $(document).ready(function() {
+ $('#myForm').ajaxForm({
+ target: '#output'
+ });
+ });
+
+ When using ajaxForm, the ajaxSubmit function will be invoked for you
+ at the appropriate time.
