在同一個集合中添加兩個項目

Question

好的，讓我重申一下這個問題。我在新的流星，我不知道如何添加 我創建了一個流星集合稱爲

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

和收集我有幾個變量，其中包括：「瓦」和「wattsbal」。

這是應用http://orozcotest.meteor.com/products1的樣品（在這個網頁我不得不手動列「瓦totales」存儲通過存儲{{wats_tot}}的信息，這是暫時，而我學習如何添加），你可以在看到更新的副本https://github.com/orozcorp/myapp.git現在我想添加分別由變量「watts」和「wattsbal」標識的列「watts」和「watts balastro」。我也有下面的模板

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); 
    } 
}) 

現在在我的javascript文件我已經嘗試了所有下面的方法，我不斷收到未定義或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; 
    } 

});

     return Session.get('.watts').value + Session.get('.wattsbal').value; 
    } 

});

Answer 1

我終於找到了答案，

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