在同一个集合中添加两个项目

Question

好的，让我重申一下这个问题。我是 Meteor 的新手，不知道如何添加 我创建了一个名为

的流星集合

Products1 = new Meteor.Collection ('products1');

在那个集合中，我有几个变量，包括：“watts”和“wattsbal”。

这是应用程序http://orozcotest.meteor.com/products1 的示例（在此网页中，我必须通过将信息存储在{{wats_tot}} 中手动存储“Watts totales”列，这是在我学习如何添加时暂时）你可以看到https://github.com/orozcorp/myapp.git 中的更新副本现在我想添加分别由变量“watts”和“wattsbal”标识的“watts”和“watts balastro”列。我也有以下模板

Template.product1Form.events({
    'click .save':function(evt,tmpl){
        var codigo = tmpl.find('.codigo').value;
        var tipo = tmpl.find('.tipo').value;
        var watts = tmpl.find('.watts').value;
        var wattsbal = tmpl.find('.wattsbal').value;
        var watts_tot = tmpl.find('.watts_tot').value;
        var precio = tmpl.find('.precio').value;
        var precio_bal = tmpl.find('.precio_bal').value;
        var numbal = tmpl.find('.numbal').value;
        var mo = tmpl.find('.mo').value;
        var horasvid = tmpl.find('.horasvid').value;
        var lux_watt = tmpl.find('.lux_watt').value;
        if(Session.get('editing_product1')){
            updateProduct1(codigo,watts, tipo, watts_tot, precio, precio_bal, numbal, mo, horasvid, wattsbal, lux_watt);
        } else{
            addProduct1(codigo,watts, tipo, watts_tot, precio, precio_bal, numbal, mo, horasvid, wattsbal, lux_watt);   
        }
        Session.set('showProduct1Dialog',false);
        Session.set('editing_product1',null);
    },
    'click .cancel':function(evt,tmpl){
        Session.set('showProduct1Dialog',false);
        Session.set('editing_product1',null);
    },
    'click .remove':function(evt,tmpl){
        removeProduct1();   
        Session.set('showProduct1Dialog',false);
        Session.set('editing_product1',null);
    }
})

现在在我的 javascript 文件中，我尝试了以下所有方法，但我不断收到 undefined 或 NaN

Template.product1Row.helpers ({
    wattstotales1 : function(){
        var watts = tmpl.find('.watts').value;
        var wattsbal=tmpl.find('.wattsbal').value;
        var wattstotales = Number(watts) + Number (wattsbal);
        return wattstotales;
    }

});

    wattstotales2 : function(){
        return Session.get('.watts').value + Session.get('.wattsbal').value;
    }

});

Template.product1Row.helpers ({

Answer 1

终于找到答案了，

    Template.product1Row.helpers ({
    wattstotales : function (){
         var total = Number(this.watts) + Number(this.wattsbal);
         return total;
         }
     })
