具有可填写字段的动态图章

我是杂技演员中这个脚本代码的新手。 我想创建一个动态图章，用户可以在其中输入各种数据，例如公司名称/帐号/批准日期/日期（生成今天的日期）/支付账单（会说"批准，N/A，）

通过搜索网络，我在这里和那里找到了一些代码，我想出了这个：但到目前为止，我没有运气。我做错了什么。

var dialog = {
companyValue: "",
accountValue: "",
approvedValue: "",
payValue: "",
        commit:function (dialog) { // called when OK pressed 
                var results = dialog.store();
                this.companyValue = results["txt1"];
                this.accountValue = results["txt2"];
                this.approvedValue = results["txt3"];
                this.payValue = results["txt4"];
        },
