本文介绍了模块化JS:3个部分(复选框和收音机)的全局功能&顺便说一句，我将“渲染"应用于在我的代码中?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是我的Web应用程序上的一个部分，用户可以在此部分订阅"在3个不同时间发送的报告:每周，每月，每季度. (可以从三个选项中选择一个).
This is a section on my web app where a user can "subscribe" to a report sent in 3 different times: weekly, monthly, quarterly. (can choose 1 option from each of the three).
我在为此计划最佳解决方案的同时都在为代码模式而苦苦挣扎.
I am struggling with both planning the best solution for this while struggling with the code pattern.
会发生什么:
-
在加载页面时，我必须传递一个PHP变量，该变量将设置用户报告的当前状态(以代码[{weekly}，{Monthly}，{Quarterly }])0,1,2,3将成为指标.例如:如果用户过去设置了每月要6个月的报告-他将看到选中每月"的复选框-并在单选按钮中选中"6个月"，变量将设置为
[0,2,0]
选中一个复选框时，可以选择3个(或一个)单选按钮.
When selecting a checkbox - the 3 (or one) radio buttons are enabled to select.
取消选中复选框时，单选按钮将被禁用，所有检查都将被删除.
When unchecking a checkbox - the radio buttons are disabled and all checks are deleted.
保存时间表"按钮会将数据发送到PHP.
"Save Schedule" button will send the data to PHP.
我的问题是:
-
如何以模块化方式构造代码，以防止出现意粉代码?
How do I structure my code in a modular way, preventing spaghetti code?
解决了1号问题后-我应该应用渲染"功能吗? (受此视频教程的启发)
After solving problem no.1 - should I apply a "render" function? (inspired by this video tutorial)
只需提及:
-
这是带有我的代码的JSFIDDLE，其意大利面条更少.-包括当前内容工作中.
This is a JSFIDDLE with my code with less spaghetti. - includes what currently is working.
我正在练习模块化JS代码，因此，我很乐意获得有关我的代码的一般提示(推荐的链接，视频和教程等).
I am practicing modular JS code, so I'll be more than happy to get general tips referring to my code (recommended links, videos and tutorials ect).
我正在使用jQuery 1.3.2，它不包含当前库的所有功能. (如parents和on.('click', func..)
I am using jQuery 1.3.2 which do not include all functionalities of the current library. (like parents and on.('click', func..)

推荐答案
只要复选框或广播btns有任何更改，就使用渲染:
Used render whenever there is any change via checkboxes or radio btns:
<script type="text/javascript">
/******************/
/** Set Schedule **/
/******************/
(function() {
var schedule = {
// get reports via php
report: [<?php echo implode(', ', $current_report); ?>],
/******************/
/* Init functions */
/******************/
init: function() {
this.cacheDom();
this.bindEvents();
this.render();
},
// Cache elements from DOM
cacheDom: function() {
this.cachedReport = this.report.slice();
this.$setScheduleBtn = $('#setScheduleBtn');
this.$reportSchedule = $('#reportSchedule');
this.$allFieldsets = this.$reportSchedule.find('fieldset');
this.$checkboxBtns = this.$allFieldsets.find('input[type="checkbox"]');
this.$radioBtns = this.$allFieldsets.find('input[type="radio"]');
this.$saveBtn = this.$reportSchedule.find('#saveSchedule');
},
// Set events
bindEvents: function() {
var that = this;
// Show/Hide "Set report" section
this.$setScheduleBtn.click(this.showReportScheduler.bind(this));
// Checkbox-radio buttons clicks
this.$allFieldsets.each(function() {
let fieldset = this;
$(this).find('input[type=checkbox]').change(function () {
that.toggleRadioButtons(fieldset);
});
});
// Update 'report' checkbox on change
this.$checkboxBtns.change(function(){
that.checkboxSaveOnChange(this);
});
// Update 'report' radio on change
this.$radioBtns.change(function(){
// console.log(reportit);
that.radioSaveOnChange(this);
});
// Save button apply changes
this.$saveBtn.click(this.saveSchedule.bind(this));
},
// Renderng data
render: function() {
var newData = this.report;
var that = this;
this.$allFieldsets.each(function(i) {
let fieldset = this;
var $theCheckbox = $(fieldset).find('input[type="checkbox"]');
var radios = $(fieldset).find("input[type=radio]");
switch ( newData[i] ) {
case 0:
$theCheckbox.attr("checked", false);
radios.attr("disabled", radios.attr("disabled"));
radios.removeAttr('checked');
break;
case 1:
$theCheckbox.attr("checked", true);
radios.attr("disabled", !radios.attr("disabled"));
radios.eq(0).attr("checked", true);
break;
case 2:
$theCheckbox.attr("checked", true);
