backbone.js - Backbonejs -collection is not defined -

-

i'm getting collection not defined error in backbone.

var categorylist = backbone.view.extend({     el:'#content',     render: function() {         var = this;         var cats = new categories();         cats.fetch({             success: function(cats) {                 var template = _.template($('#category-list-template').html(), {cats: cats.models});                 cats.each(function(it) {                     console.log(it.tojson());                 });                 that.$el.html(template);             }         })     } });

and in script i'm running each loop add data table, i'm getting 'cats not defined error'. 

<script type="text/template" id="category-list-template">             <table class="table striped">            <thead>            <tr>            <td>id</td>            <td>name</td>            </tr>            </thead>            <tbody>            <% _.each(cats, function(category) { %>             <tr>             <td><%= category.name %>    </td>             </tr>            <% }); %>            </tbody>             </table>      </script>

you have transform collection plain javascript object using tojson method.

var template = _.template($('#category-list-template').text()); var result = template({collection: cats.tojson()}); that.$el.html(result);
