I am trying to render a basic backbone view with an underscore template, but I keep getting the following error when attempting to render the template.
Uncaught ReferenceError: amount is not defined
here's the jsfiddle: http://jsfiddle.net/rkj6j36n/
HTML
<body>
<div class="msg-con"></div>
</body>
JS
DumbViewObj = Backbone.View.extend({
el: $('.msg-con'),
initialize:function(){
this.render();
},
render: function(){
var template = _.template('I am <%= amount %> dumb',{amount:'200'});
this.$el.append(template);
},
});
var dumb = new DumbViewObj();
I'm sure the solution is something dead simple, but I can't figure it out

Because template is a function and template( obj ) returns the string you are after, it does not return the string after you call it.
What your code is doing
var xxx = template();
this.$el.append(xxx);
what you should be doing
render: function(){
var template = _.template($('#dumb').html());
var vars = {amount:200};
var html = template(vars);
this.$el.append(html);
},
in one line:
this.$el.append(_.template('I am <%= amount %> dumb')({amount:200}))
_.template compiles the template into a function. You have to pass the parameters to the resulting function to be evaluated:
var template = _.template('I am <%= amount %> dumb');
this.$el.append(template({amount:'200'}));
