javascript - 如何使用表单更新现有的 JS 对象 - Angular JS

Question

我正在将我现有的项目转换为 angularJs，并且有一个 JS 对象 I，我在表单提交时不断更新。

autoquoteDTO.js:

$.getAutoQuoteObject = function() {

prapareJson.js:

var prepareAutoQuoteDTO = {
    postAutoQuoteObj: $.getAutoQuoteObject(),  
    initializeDriverObj: function()
    {
        var driverLocObj           = new Driver();
        driverLocObj.PersonInfo    = new PersonInfo();
        driverLocObj.DriverLicense = new DriverLicense();
        driverLocObj.Incident      = new Incident();
        return driverLocObj;
    },

    initializeAppInfo: function()
    {
        var appInfoLocObj           = new ApplicationInfo();
        appInfoLocObj.Discount      = new Discount();
        return appInfoLocObj;

    },
    /*
    * Initialize Vehicle object for autoQuoteDTO.js
    */
    initializeVehicleObj: function()
    {
        var vehicleLocObj = new Vehicle();
        return vehicleLocObj;
    },

    rc1Step1DTO: function()
    {
       /*
        * store session info
        */
        var emailId = $('#save_quote_email').val();
        if (typeof emailId  !== "undefined" && emailId && emailId != '' && emailId != 'Email Address')
        {
            var email           = new Email();
            email.EmailTypeCd   = 'PRIMARY';
            email.EmailAddress  = emailId;
            this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo = this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo || new Contact();
            this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo.Emails = [];
            this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo.Emails.push(email);
        }
};

更新用户事件代码的 json:

prepareAutoQuoteDTO.rc1Step1DTO();

应该更新 JS 对象的新 Angular JS 代码:

 (function(){
    "use strict";
    angular
    .model("autoQuote")
    .controller("prepareDTO","prepareDTO")
    .controller("postDTO","postDTO");
        /*
         * Call actions on page load
         */
    var init = function () {
                 prepareDTO();    
        }
        init();

        /*
         * prepare DTO with form elements.
         */
        function prepareDTO()
    {
         var vm = this;
         vm.postAutoQuoteObj = [];   
    }

        /*
         * post DTO on form submit and page onload.
         */
        function postDTO()
        {

        }     

 });

表单逻辑应包含在 prepareDTO 函数中。

预期的行为是如果提交了 step1 表单，则应调用 rc1Step1DTO 并保存 JS 数据。

寻找实现此目标的建议和最佳实践。

我可以删除/编辑这个文件和 Angular JS 中的所有内容，但我不知道如何在 AngularJS 中执行此操作。

您可以将所有代码移至工厂，然后将其注入(inject) Controller 。您的所有其他依赖项(如 Driver)必须在此执行之前包括在内，甚至可以在 prepareDtoFactory 函数中声明。

angular
.model("autoQuote")
.controller(dtoController)
.factory(prepareDtoFactory);

function dtoController(prepareDtoFactory){
     prepareDtoFactory.rc1Step1DTO(); //call function from your service, and do something with it
}

dtoController.$inject = ['prepareDtoFactory'];

function prepareDtoFactory(){

    var prepareAutoQuoteDTO = {
        postAutoQuoteObj         : $.getAutoQuoteObject(),  
        initializeDriverObj: function(){
            var driverLocObj           = new Driver();
            driverLocObj.PersonInfo    = new PersonInfo();
            driverLocObj.DriverLicense = new DriverLicense();
            driverLocObj.Incident      = new Incident();
            return driverLocObj;
       },
       initializeAppInfo: function(){
           var appInfoLocObj           = new ApplicationInfo();
           appInfoLocObj.Discount      = new Discount();
           return appInfoLocObj;
       },
       /*
       * Initialize Vehicle object for autoQuoteDTO.js
       */
       initializeVehicleObj: function(){
           var vehicleLocObj = new Vehicle();
           return vehicleLocObj;
       },
       /*
       * store session info
       */
       rc1Step1DTO: function(){

            var emailId = $('#save_quote_email').val();
            if (typeof emailId  !== "undefined" && emailId && emailId != '' && emailId != 'Email Address'){
                var email           = new Email();
                email.EmailTypeCd   = 'PRIMARY';
                email.EmailAddress  = emailId;
                this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo =     this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo || new Contact();
                this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo.Emails = [];
                this.postAutoQuoteObj.ApplicationInfo.GeneralPartyInfo.ContactInfo.Emails.push(email);
            }
        }
    };
    return prepareAutoQuoteDTO;
}
