骨干渲染视图多次

Question

I have a backbone.js app where I have a view like:

var StoreView = Backbone.View.extend({
el: ".container",
initialize: function() {
    this.render();
},

events: {
    "click #addProduct": "addProduct",
},

render: function() {
    this.$el.html(render("index"));
},

addProduct: function(){
    var productView = new StoreProductView({
        el: $('#products')
    });
    productView.render();
}
});

and my StoreProductView looks like:

var StoreProductView = Backbone.View.extend({
render: function () {

    this.$el.html(render("products/product"));

    return this;
}
});

So when I click #addProduct, a new StoreProductView template is called. But if you hit #addProduct again, nothing happens. How can I get it so that for each time #addProduct is hit, a new StoreProductView is rendered? So if I hit it x number of times, there is x StoreProductView s?

Answer 1

you need to change this line:

this.$el.html(render("products/product"));

to this for example:

this.$el.append(render("products/product"));

because every time you substitute the html and nw you don't append, only remove html content and insert the new one. With append() you can add anoter product.
