Backbone view not refresh event

Question

I have one view ( HomeView ) render template using text! plugin. This is Home view :

var HomeView = Backbone.View.extend({
   initialize: function() {
        myCart.updateQtyLabel("qtyCart");
   },
   el: '#webbodycontainer',
   events : {
       "click #addToCart" :  function(){
           myCart.addToCart(newItem);
           myCart.updateQtyLabel("qtyCart");
           $("#containernewpromotion").html(promotionItem);
       }
   },
   render : function(){
       this.$el.html(homePanel);
       $("#containernewpromotion").html(promotionItem);
   }
});

This is html template :

<% var items = deserializeJSONToObj(localStorage.getItem("Cart"));%>
  <%  if(items != null){  %>
    <% var i = 0; %>
       <% _.each(items, function(item) { %>
          <% if (i < 4){ i++; } else { return false; }%>
          <div class="promotionColumn">
             <div class="itemImg">
                  <a href="#itemDetail"><img src="<%=WebConfig.PartImageBrand + item.PictureName%>" width="135px"/></a>
             </div>
          </div>
  <% }); %>
<% } %>

This is itemDetail view :

 var ItemDetailView = Backbone.View.extend({
    initialize: function() {
        alert("test");
    },
    render: function(){
        alert("test2");
    }
});

When I click on <a href="#itemDetail"> , I got a warning message in chrome console event.returnValue is deprecated. Please use the standard event.preventDefault() instead. event.returnValue is deprecated. Please use the standard event.preventDefault() instead. , and alert in ItemDetailView is not working.

The url goes /#itemDetail but the template used in HomeView still displayed in itemDetail router. HomeView content is dropped from itemDetail page when I press refresh in my browser.

Any idea what could be causing this please. Thanks.

Answer 1

The events object in a backbone view is of the following structure

"events" : {
    "event selector" : "handler"
},
"handler" : function(){

}

The value in the events object is a string, not a function.
