是从模板呈现的select,并且在被调用之前不存在于 DOMrenderGroups()中。

我认为这些事件是绑定到视图的,所以如果选择一开始在 DOM 中不存在并不一定重要?

我是新手,backbone.js所以它可能很明显:

var DirectoryView = Backbone.View.extend({
    el: $("table tbody"),
    initialize: function(){
        // Populate our collection
        this.collection = new Directory(contacts);

        // Get our unique groups
        var groups = this.getGroups();
        this.renderGroups(groups);
    },

    renderGroups: function(groups) {
        var group = $("#groups");

        var groupView = new GroupView({
            model: {groups: groups}
        })

        group.append(groupView.render().el)

    },

    events : {
        "change select" : "select"
    },

    select: function(e) {
        console.log("hello")
    },

    getGroups: function() {
        // Pluck all the group properties from our array of contacts and return the unique groups
        return _.uniq(this.collection.pluck("group"), false, function(group){
            return group.toLowerCase();
        });
    }
});

模板

    <script id="group-option-tmpl" type="text/template">
        <option value="all">All</option>
        <% _.each(groups, function(group) { %>
            <option value="<%= group %>"><%= group %></option>
        <% }); %>
    </script>
