模型不发送删除请求销毁

Question

sil是删除事件，但它不发送删除请求方法。

var NoteModel = Backbone.Model.extend({ 
    urlRoot:"/DenemeBackbone/webresources/com.mycompany.denemebackbone.note", 
    defaults: { 
     note: "Boş" 
    } 
}); 

我有两个看法。

var NoteView = Backbone.View.extend({ 
    tagName: "tr", 
    template: "<td> <span>{{note}}</span><input type='text' value='{{note}}' style='width: 190px;display: none;'/><button class='btn btn-danger btn-mini' style='float: right;'>Sil</button> </td>", 
    model: {}, 
    events: { 

     "click button":"sil" 
    } 

    sil:function(){ 
     this.model.destroy(); // HTTP DELETE 
     this.remove(); 
     alert(this.model.note); 
    } 

}); 

Answer 1

如果你看看the source你可以看到正在发生的事情，

如果this.model.isNew()是真的，那么这将不会发送XHR删除。 isNew()返回this.id == null，所以为了删除它，你应该为它分配一个id。

即。

var myNote = new NoteModel({ 
id : 'myid' 
}); 

Answer 2

但没有运行。

var NoteModel = Backbone.Model.extend({ 
    urlRoot:"/Deneme2/resources/com.mycompany.deneme2.note", 
    id:null, 
    defaults: { 
     note: "" 
    } 

}); 

var NoteView = Backbone.View.extend({ 
    tagName: "tr", 
    template: "<td> <span>{{note}}</span><input type='text' value='{{id}}' style='width: 190px;display: none;'/><button class='btn btn-danger btn-mini' style='float: right;'>Sil</button> </td>", 
    model: {}, 
    events: { 
     "dblclick span": "duzenlemeModu", 
     "blur input": "duzenle", 
     "click button":"sil" 
    }, 
    duzenlemeModu: function() { 
     this.$el.find("input").css("display", ""); 
     this.$el.find("span").css("display", "none"); 
    }, 
    duzenle: function() { 
     this.model.save("note",this.$el.find("input").val()); // HTTP PUT 
     this.render(); 

     this.$el.find("input").css("display", "none"); 
     this.$el.find("span").css("display", ""); 
    }, 
    sil:function(){  
     this.model.destroy(); // HTTP DELETE 
     this.remove(); 
    } , 
    render: function() { 
     var html = Mustache.to_html(this.template, this.model.toJSON()); 
     $(this.el).html(html); 

     return this; 
    } 
}); 

var AppView = Backbone.View.extend({ 

    el: $("body"), 
    events: { 
     "keypress #note": "kaydet" 
    }, 
    kaydet: function (evt) { 

     if (evt.keyCode !== 13) return; 

     var noteModel = new NoteModel(); 
     noteModel.set("note", $("#note").val()); 

     noteModel.save(); // HTTP POST 

     var noteView = new NoteView(); 
     noteView.model = noteModel; 

     $(".table").append(noteView.render().el); 
     $("#note").val(""); 
    } 
}); 

var appView = new AppView();
