我已经按照stickit文档中的建议，在初始化函数中插入了autocomplete。

几乎是hello world示例：

MyApp.Views.Form = Backbone.View.extend({
    el: "#my-form",
    bindings: {
        "#postcode_with_suburbs": {
            observe: "postcode",
            initialize: function($el, model, options) {
                $el.autocomplete({
                    source: [ "c++", "java", "php", "coldfusion", "javascript", "asp", "ruby" ] 
                })
            },
            onSet: function(val, options) {
                return $("#postcode_with_suburbs").val(); 
            }
        },
    },
    events: {
        "click #form-submit" : "submit",
    },
    initialize : function() {
            this.listenTo(this.model, "change");
            this.render();
    },
    render: function() {
        this.$el.html(JST['backbone/templates/car_insurance/form']);
            this.stickit();
        return this;
    }
});

因此，问题在于，每当用户填写表单并通过单击“自动完成”值自动复制邮政编码时，它不会保存到“模型”属性中<代码>另存为ja而不是java

然而，在自动完成的选项上用键盘向下滚动，这些值被正确地设置为模型的属性。保存为java
