我有一个骨干项目，可以从各种 API 中提取播客。
我要解决的问题是删除当前显示的所有视图。我想通过将事件绑定到单击“删除”锚点时触发的每个视图来做到这一点。
目前，集合重置触发并删除所有模型，但我无法确保视图也被销毁。我想我的逻辑需要帮助。
这是我的代码：
podSearch = Backbone.Model.extend();
podSearchCollection = Backbone.Collection.extend({
model: podSearch,
parse: function(response) {
return response.results;
}
});
ownerList = Backbone.Model.extend();
ownerListCollection = Backbone.Collection.extend({
model: ownerList,
parse: function(response) {
return response.results;
}
});
Search = Backbone.View.extend({
initialize: function(){
this.searchCollection = new podSearchCollection();
this.searchCollection.bind('reset', this.appendResult, this);
},
events: {
"click button" : "getTerm"
},
doSearch: function(term){
/* get term and collection url */
this.searchCollection.fetch();
},
appendResult: function(){
_.each(this.searchCollection.models, function (item) {
var listItem = new ownerItem({model:item});
$('#results').append(listItem.render().el);
});
},
removeAll: function(){
console.log(this.searchCollection);
this.searchCollection.reset();
}
});
ownerItem = Backbone.View.extend({
template: $("#castOwner").html(),
initialize: function(){
this.ownerListCollection = new ownerListCollection();
this.ownerListCollection.bind('reset', this.appendResult, this);
this.model.bind("reset", this.removeSelf);
},
render: function(){
var tmpl = _.template(this.template);
this.$el.html( tmpl( this.model.toJSON() ) );
return this;
},
events: {
"click a" : "pullCasts",
"click a.removeAll" : "removeAll"
},
pullCasts: function(e){
e.preventDefault();
var id = this.$el.find('a').attr("href");
this.ownerListCollection.url = 'http://itunes.apple.com/lookup?id=' + id + '&entity=podcast&callback=?';
this.ownerListCollection.fetch();
},
appendResult: function(){
_.each(this.ownerListCollection.models, function(item){
/* do something with each item */
}, this);
$(this.el).append('<p><a href="#" class="removeAll">Remove All</a></p>');
},
removeAll: function(){
search.removeAll();
},
removeSelf: function(){
console.log("rm");
}
});
search = new Search();
