我在我的 Marionette.js 应用程序中使用带有 Backone.Validation( http://thedersen.com/projects/backbone-validation/ ) 插件的 Twitter Bootstrap3，但有些人根本无法做到这一点。任何人都可以举一个简单的例子来说明如何将 Backbone.Validation 与 Marionette.js 一起使用（类似于http://thedersen.com/projects/backbone-validation/#examples 和 _http://jsfiddle.net/thedersen/的例子c3kK2/)
更新：我有以下编码，我希望一旦提交表单就会触发验证，但不幸的是什么都没有发生，甚至没有错误。在我的 app.js （全球）
//Backbone.Validation
Backbone.Validation.configure({
forceUpdate: true
});
_.extend(Backbone.Validation.callbacks, {
valid: function (view, attr, selector) {
var $el = view.$('[name=' + attr + ']'),
$group = $el.closest('.form-group');
$group.removeClass('has-error');
$group.find('.help-block').html('').addClass('hidden');
},
invalid: function (view, attr, error, selector) {
var $el = view.$('[name=' + attr + ']'),
$group = $el.closest('.form-group');
$group.addClass('has-error');
$group.find('.help-block').html(error).removeClass('hidden');
}
});
我的模板如下所示：
<script id="signup-form" type='text/template'>
<form class="form-signin control-group">
<table>
<tr><th><h2 class="form-signin-heading">Please sign up</h2></th></tr>
<tr><td><input type="text" class="form-control" name="username" placeholder="Email address"></td></tr>
<tr><td><input type="password" class="form-control" name="password" placeholder="Password"></td></tr>
<tr><td><button class="btn btn-success form-control js-submit">Sign up</button></td></tr>
</table>
</form>
我的模型如下所示：
Entities.User = Backbone.Model.extend({
urlRoot: "signup",
defaults: {
},
idAttribute: "_id",
validation: {
email: {
required: true,
pattern: 'email'
},
password: {
minLength: 8
}
},
validate:true
});
我的观点看起来像这样
Show.SignupPanel = Marionette.ItemView.extend({
template: "#signup-form",
events: {
'click button.js-submit': 'signupClicked'
},
signupClicked: function (e) {
//stop the default action of <a> tag and page refresh
e.preventDefault();
var data = Backbone.Syphon.serialize(this);
if(this.model.isValid(true))
this.trigger("form:submit", data);
},
initialize: function () {
// This hooks up the validation
// See: http://thedersen.com/projects/backbone-validation/#using-form-model-validation/validation-binding
Backbone.Validation.bind(this);
},
remove: function () {
// Remove the validation binding
// See: http://thedersen.com/projects/backbone-validation/#using-form-model-validation/unbinding
Backbone.Validation.unbind(this);
return Backbone.View.prototype.remove.apply(this, arguments);
}
});
