ajaxForm and ajaxSubmit Options
Both ajaxForm
and ajaxSubmit
support numerous options which can be provided using plain JavaScript options
object containing any of the options below:
Note: Aside from the options listed below, you can also pass any of the standard $.ajax settings to ajaxForm and ajaxSubmit.
beforeSerialize
Default: null
Callback function to be invoked before the form is serialized. This provides an opportunity to manipulate the form before it's values are retrieved. The beforeSerialize
function is invoked with two arguments: the jQuery object for the form, and the Options Object passed into ajaxForm/ajaxSubmit.
beforeSerialize: function($form, options) {
// return false to cancel submit
}
beforeSubmit
Default: null
Callback function to be invoked before the form is submitted. The 'beforeSubmit' callback can be provided as a hook for running pre-submit logic or for validating the form data. If the 'beforeSubmit' callback returns false then the form will not be submitted. The 'beforeSubmit' callback is invoked with three arguments: the form data in array format, the jQuery object for the form, and the Options Object passed into ajaxForm/ajaxSubmit.
beforeSubmit: function(arr, $form, options) {
// The array of form data takes the following form:
// [ { name: 'username', value: 'jresig' }, { name: 'password', value: 'secret' } ]
// return false to cancel submit
}
clearForm
Default: null
Boolean flag indicating whether the form should be cleared if the submit is successful
data
Default: {}
An object containing extra data that should be submitted along with the form.
data: { key1: 'value1', key2: 'value2' }
dataType
Default: null
Expected data type of the response. One of: null, 'xml', 'script', or 'json'. The dataType
option provides a means for specifying how the server response should be handled. This maps directly to the jQuery.httpData
method. The following values are supported:
'xml': if dataType == 'xml' the server response is treated as XML and the 'success' callback method, if specified, will be passed the responseXML value
'json': if dataType == 'json' the server response will be evaluted and passed to the 'success' callback, if specified
'script': if dataType == 'script' the server response is evaluated in the global context
error
Deprecated due to incompatiblity with jQuery 3 Slim. (issue #544)
Callback function to be invoked upon error.
forceSync
Default: false
Boolean value. Set to true to remove short delay before posting form when uploading files (or using the iframe option). The delay is used to allow the browser to render DOM updates prior to performing a native form submit. This improves usability when displaying notifications to the user, such as "Please Wait…" (version added: 2.38)
iframe
Default: false
Boolean flag indicating whether the form should always target the server response to an iframe. This is useful in conjuction with file uploads. See the File Uploads documentation on the Code Samples page for more info.
iframeSrc
Default: about:blank
Default value for HTTPS pages: javascript:false
String value that should be used for the iframe's src attribute when/if an iframe is used.
iframeTarget
Default: null
Identifies the iframe element to be used as the response target for file uploads. By default, the plugin will create a temporary iframe element to capture the response when uploading files. This options allows you to use an existing iframe if you wish. When using this option the plugin will make no attempt at handling the response from the server. (version added: 2.76)
method
Default: value of form's method
attribute (or GET
if none found)
The HTTP method to use for the request (e.g. 'POST', 'GET', 'PUT'). (version added: 4.2.0)
replaceTarget
Default: false
Optionally used along with the the target
option. Set to true
if the target should be replaced or false
if only the target contents should be replaced. (version added: 2.43)
resetForm
Default: null
Boolean flag indicating whether the form should be reset if the submit is successful
semantic
Default: false
Boolean flag indicating whether data must be submitted in strict semantic order (slower). Note that the normal form serialization is done in semantic order with the exception of input elements of type="image"
.
Note: You should only set the semantic
option to true
if your server has strict semantic requirements and your form contains an input element of type="image"
.
success
Deprecated due to incompatiblity with jQuery 3 Slim. (issue #544)
Default: null
Callback function to be invoked after the form has been submitted. If a 'success' callback function is provided it is invoked after the response has been returned from the server. It is passed the following standard jQuery arguments:

, stringjqXHR
