如何删除删除集合中的模型并使删除事件触发。我试过people.remove([{ name: "joe3" }]);但它不会工作。
var Person = Backbone.Model.extend({
initialize: function () {
console.log(" person is initialized");
},
defaults: {
name: "underfined",
age:"underfined"
}
});
var People = Backbone.Collection.extend({
initialize: function () {
console.log("people collection is initialized");
this.bind('add', this.onModelAdded, this);
this.bind('remove', this.onModelRemoved, this);
},
model: Person,
onModelAdded: function(model, collection, options) {
console.log("options = ", options);
alert("added");
},
onModelRemoved: function (model, collection, options) {
console.log("options = ", options);
alert("removed");
},
});
//var person = new Person({ name: "joe1" });
var people = new People();
//people.add([{ name: "joe2" }]);
people.add([{ name: "joe1" }]);
people.add([{ name: "joe2" }]);
people.add([{ name: "joe3" }]);
people.add([{ name: "joe4" }]);
people.add([{ name: "joe5" }]);
people.remove([{ name: "joe3" }]);
console.log(people.toJSON());
最佳答案
对于其他寻找删除位置的人，您可以简单地使用 collection.where 调用将其链接起来。像这样删除与搜索匹配的所有项目:
people.remove(people.where({name: "joe3"}));
见 Backbone collection.where
