These 58 functions are mutually exclusive. Use ajaxSubmit if you want 59 to bind your own submit handler to the form. For example, 60 61 $(document).ready(function() { 62 $('#myForm').on('submit', function(e) { 63 e.preventDefault(); // <-- important 64 $(this).ajaxSubmit({ 65 target: '#output' 66 }); 67 }); 68 }); 69 70 Use ajaxForm when you want the plugin to manage all the event binding 71 for you. For example, 72 73 $(document).ready(function() { 74 $('#myForm').ajaxForm({ 75 target: '#output' 76 }); 77 }); 78 79 You can also use ajaxForm with delegation (requires jQuery v1.7+), so the 80 form does not have to exist when you invoke ajaxForm: 81 82 $('#myForm').ajaxForm({ 83 delegation: true, 84 target: '#output' 85 }); 86 87 When using ajaxForm, the ajaxSubmit function will be invoked for you 88 at the appropriate time. 89 */ 90 91 var rCRLF = /\r?\n/g; 92 93 /** 94 * Feature detection 95 */ 96 var feature = {}; 97 98 feature.fileapi = $('<input type="file">').get(0).files !== undefined; 99 feature.formdata = (typeof window.FormData !== 'undefined'); 100 101 var hasProp = !!$.fn.prop; 102 103 // attr2 uses prop when it can but checks the return type for 104 // an expected string.
