我认为代码会更好地解释我的问题: 观点:
App.Views.ErrorModal = Backbone.View.extend({
template: window.template('errorModal'),
render: function(){
this.$el.html(this.template(this.model.toJSON()));
this.$("#errorApproveModal").modal({
keyboard: true
});
return this;
}
});
实例化时:
var error = new App.Models.Errors({title: "Exporting Error", content: "Error"});
var errorModal = new App.Views.ErrorModal({model: error});
errorModal.render();
加载了模态,但我只得到一个空div
感谢您的帮助! 罗伊

最好创建一个包含所有Modal逻辑的单独类,然后从主视图中调用它。
尝试使用this approach。
模态JS
var BaseModalView = Backbone.View.extend({
id: 'base-modal',
className: 'modal fade hide',
template: 'modals/BaseModal',
events: {
'hidden': 'teardown'
},
initialize: function() {
_.bindAll(this, 'show', 'teardown', 'render', 'renderView');
this.render();
},
show: function() {
this.$el.modal('show');
},
teardown: function() {
this.$el.data('modal', null);
this.remove();
},
render: function() {
this.getTemplate(this.template, this.renderView);
return this;
},
renderView: function(template) {
this.$el.html(template());
this.$el.modal({show:false}); // dont show modal on instantiation
}
});
把手模板
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<a href="#" class="btn">Close</a>
<a href="#" class="btn btn-primary">Save changes</a>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
父视图 //点击按钮后点击
modalView = new BaseModalView();
modalView.show();
// Modal view automatically bound to the body and removes itself on hidden;

我们可以扩展此视图以向其添加更多功能。我们也可以传递数据到init上查看。
/**
* ModalView
* @version 0.0.1
*/
var ModalView = Backbone.View.extend({
tpl: JST['modal-tpl'],
className: 'modal-view',
events: {
'evt:show': 'show',
'evt:hide': 'hide',
},
initialize: function(options) {
this.options = options;
_.bindAll(this, 'render', 'show', 'hide', 'remove');
this.render();
},
render: function() {
this.$el.html(this.tpl(this.options));
this.$el.appendTo('body');
this.$modal = this.$('.modal');
this.$modal.on('hidden.bs.modal', _.bind(function() {
this.close();
}, this));
},
show: function() {
this.$modal.modal('show');
},
hide: function() {
this.$modal.modal('hide');
},
close: function() {
//unbind events
this.unbind();
//Remove html from page
this.remove();
},
});
//Pass modal data on init
var modal = new ModalView({
modalContent: 'Hello User!'
});
modal.show();
//modal.trigger('evt:show');
<!-- Modal -->
<div class="modal fade" tabindex="-1" role="dialog" aria-labelledby="modal-label">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="modal-label">Modal</h4>
</div>
<div class="modal-body">
{{{modalContent}}}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>

看起来你永远不会将它添加到页面中。
var errorModal = new App.Views.ErrorModal({model: error});
$('#my-div').html(errorModal.el);
errorModal.render();
我假设bootstrap-modal与大多数jquery插件一样,在调用之前需要html在页面上。

尝试从模态视图中删除淡入淡出和隐藏类。
