Question

好的，让我重申一下这个问题。我是Meteor的新手，我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');

在那个系列中我有几个变量，包括：“watts”和“wattsbal”。

这是应用http://orozcotest.meteor.com/products1的一个示例（在此网页中，我必须手动存储“Watts totales”列，方法是将信息存储在{{wats_tot}}这是我学习如何添加的时候您可以在https://github.com/orozcorp/myapp.git中看到更新的副本，现在我想添加分别由变量“watts”和“wattsbal”标识的列“watts”和“watts balastro”。我还有以下模板

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，并且我一直未定义或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;
    }

});

Template.product1Row.helpers ({
    wattstotales2 : function(){
        return Session.get('.watts').value + Session.get('.wattsbal').value;
    }

});

Template.product1Row.helpers ({
    wattstotales3 : function(){

Answer 1

我终于找到了答案，

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

在同一个Collection中添加两个项目
