我試圖使用主幹從表單保存我的模型時出現問題。在這裏,我想我的我的觀點實際上是一個編輯表單:Backbone.js model.save()在下劃線中激發「太多的遞歸」錯誤
(function() {
'use strict';
var YachtEditor = {};
window.YachtEditor = YachtEditor;
var template = function(name) {
return Mustache.compile($('#' + name + 'Template').html());
};
YachtEditor.Tank = Backbone.Model.extend({
defaults : {
dCapacity : "",
sType : ""
}
});
YachtEditor.Tanks = Backbone.Collection.extend({
// url: "/rest/tanks",
localStorage: new Store("tanks"),
model : YachtEditor.Tank
});
YachtEditor.TankView = Backbone.View.extend({
template: template("tank"),
events: {
'click .save' : 'save',
'click .remove' : 'remove'
},
initialize: function() {
console.log("initialize tank View :");
console.log(this.model.get("id"));
},
render: function() {
this.$el.html(this.template(this));
return this;
},
save: function() {
console.log('change');
var self = this;
var values = {
sType: self.$("#sType").val(),
dCapacity: self.$("#dCapacity").val()
};
console.log("dCapacity : " + values.dCapacity);
console.log("sType : " + values.sType);
this.model.save(values);
},
remove: function() {
this.model.destroy();
},
dCapacity : function() {
return this.model.get("dCapacity");
},
sType : function() {
return this.model.get("sType");
}
});
YachtEditor.TanksView = Backbone.View.extend({
el: $("div.tankZone"),
template: template("tanks"),
events: {
"click .add" : "addTank",
"click .clear" : "clear"
},
initialize: function() {
this.tanks = new YachtEditor.Tanks();
// this.tanks.on('all', this.render, this);
this.tanks.fetch();
this.render();
},
render: function() {
this.$el.html(this.template(this));
this.tanks.each(this.renderTank, this);
return this;
},
renderTank: function(tank) {
var view = new YachtEditor.TankView({model: tank});
$(".tanks").append(view.render().el);
return this;
},
addTank: function() {
this.tanks.create({});
this.render();
},
clear: function() {
this.tanks.each(function(tank) {
tank.destroy();
});
this.render();
}
});
...
})();
這裏是我使用的每個罐的鬍子模板
<script id="tankTemplate" type="text/x-mustache-template">
<div class="tankView">
<h1>Tank</h1>
<select id="sType" value="{{ sType }}">
@for(option <- Tank.Type.values().toList) {
<option>@option.toString</option>
}
</select>
<input id="dCapacity" type="text" value="{{ dCapacity }}">
<button class="destroy">x</button>
</div>
</script>
我在這裏的問題是,this.model.save()觸發器下劃線中的'遞歸太多'。 JS。 (鉻也顯示錯誤
這裏是錯誤的調用堆棧:
_.extend
_.clone
_.extend.toJSON
_.extend.save
_.extend.update
Backbone.sync
_.extend.sync
_.extend.save
YachtEditor.TankView.Backbone.View.extend.save
st.event.dispatch
y.handle
我懷疑保存召回blur事件,但我不能找到一種方法來明確它...也許我?「M沒有使用支柱,我應該
我沒有看到任何明顯錯誤的代碼,你能錯誤的堆棧跟蹤,以便我們可以知道哪個方法遞歸調用? –
我更新了帖子,讓你看到錯誤調用堆棧 – stamm
