Usage Note:

[54] Fix | Delete

-----------

[55] Fix | Delete

Do not use both ajaxSubmit and ajaxForm on the same form. These

[56] Fix | Delete

functions are mutually exclusive. Use ajaxSubmit if you want

[57] Fix | Delete

to bind your own submit handler to the form. For example,

[58] Fix | Delete

[59] Fix | Delete

$(document).ready(function() {

[60] Fix | Delete

$('#myForm').on('submit', function(e) {

[61] Fix | Delete

e.preventDefault(); // <-- important

[62] Fix | Delete

$(this).ajaxSubmit({

[63] Fix | Delete

target: '#output'

[64] Fix | Delete

});

[65] Fix | Delete

});

[66] Fix | Delete

});

[67] Fix | Delete

[68] Fix | Delete

Use ajaxForm when you want the plugin to manage all the event binding

[69] Fix | Delete

for you. For example,

[70] Fix | Delete

[71] Fix | Delete

$(document).ready(function() {

[72] Fix | Delete

$('#myForm').ajaxForm({

[73] Fix | Delete

target: '#output'

[74] Fix | Delete

});

[75] Fix | Delete

});

[76] Fix | Delete

[77] Fix | Delete

You can also use ajaxForm with delegation (requires jQuery v1.7+), so the

[78] Fix | Delete

form does not have to exist when you invoke ajaxForm:

[79] Fix | Delete

[80] Fix | Delete

$('#myForm').ajaxForm({

[81] Fix | Delete

delegation: true,

[82] Fix | Delete

target: '#output'

[83] Fix | Delete

});

[84] Fix | Delete

[85] Fix | Delete

When using ajaxForm, the ajaxSubmit function will be invoked for you

[86] Fix | Delete

at the appropriate time.
