需要引用 jquery.js ， bootstrap.js， jquery.validate.js 库
2、form.js 代码
var MyValidator = function() {
var handleSubmit = function() {
$('.form-horizontal').validate({
errorElement : 'span',errorClass : 'help-block',focusInvalid : false,rules : {
name : {
required : true
},password : {
required : true
},intro : {
required : true
}
},messages : {
name : {
required : "Username is required."
},password : {
required : "Password is required."
},intro : {
required : "Intro is required."
}
},highlight : function(element) {
$(element).closest('.form-group').addClass('has-error');
},success : function(label) {
label.closest('.form-group').removeClass('has-error');
label.remove();
},errorPlacement : function(error,element) {
element.parent('div').append(error);
},submitHandler : function(form) {
form.submit();
}
});
$('.form-horizontal input').keypress(function(e) {
if (e.which == 13) {
if ($('.form-horizontal').validate().form()) {
$('.form-horizontal').submit();
}
return false;
}
});

return {
init : function() {
