The form provides several methods to perform actions with form fields, such as ajax submission, loading, clearing, etc. When submitting the form, the 'validate' method is called to check if the form is valid. ## Usage Create a simple HTML form. Build the form and assign id, action, and method. ... Make the form an ajax submission form. $('#ff').form({ url:..., onSubmit: function(){// do some check// return false to prevent submit; }, success:function(data){alert(data) }});// submit the form $('#ff').submit(); Perform a submit action. // call 'submit' method of form plugin to submit the form $('#ff').form('submit', { url:..., onSubmit: function(){// do some check// return false to prevent submit; }, success:function(data){alert(data) }}); Submit with extra parameters. $('#ff').form('submit', { url:..., onSubmit: function(param){param.p1 = 'value1';param.p2 = 'value2'; }}); #### Handling the Submit Response Submitting an ajax form is very simple. When the submission is complete, the user can get the response data. Please note that the response data is the raw data from the server. Parsing the response data requires obtaining the correct data. For example, assuming the response data is in JSON format, a typical response data looks like this: { "success": true, "message": "Message sent successfully."} Now handle the JSON string in the 'success' callback function. $('#ff').form('submit', { success: function(data){var data = eval('(' + data + ')'); // change the JSON string to javascript objectif (data.success){alert(data.message)} }}); ## Properties | Name | Type | Description | Default | | --- | --- | --- | --- | | url | string | The URL of the form action to submit to. | null | ## Events | Name | Parameters | Description | | --- | --- | --- | | onSubmit | param | Fires before submit, return false to prevent the submit action. | | success | data | Fires when the form is submitted successfully. | | onBeforeLoad | param | Fires before a request is made to load data.
