【开发方案】KaiOS APN 设置界面菜单选项定制

一、模块需求介绍

参考：KaiOS APN Settings模块代码-CSDN博客

APN 列表页对每一条APN提供编辑、删除等功能 ，对APN整体提供reset重置功能。

当前需要隐藏reset，不允许用户重置APN。

二、代码实现方案

APN列表页在gaia/apps/settings/应用中，在panel.js设置菜单选项，接口registerSoftkey。

• gaia/apps/settings/elements/apn_lists.html 定义了 APN Settings界面的结构和布局
• gaia/apps/settings/js/panels/apn_list/panel.js 功能逻辑
• gaia/apps/settings/js/panels/apn_list/apn_template_factory.js 界面模板

apn_list/panel.js

/**
 * The apn list panel
 */
'use strict';
define(function(require) { //eslint-disable-line
  const ListView = require('modules/mvvm/list_view');
  const SettingsPanel = require('modules/settings_panel');
  const ApnSettingsManager = require('modules/apn/apn_settings_manager');
  const ApnTemplateFactory = require('panels/apn_list/apn_template_factory');
  return function createApnSettingsPanel() {
 
    //设置案件
    function registerSoftkey() {
      //1.左边：添加APN
      const softkeyAdd = {
        name: 'Add Apn',
        l10nId: 'add-apn',
        priority: 1,
        method: () => {
          onApnAddAction(serviceIdNum, apnType, rootElement);
        }
      };
      //2.中间：选中APN
      const softkeySelect = {
        name: 'Select',
        l10nId: 'select',
        priority: 2,
        method: () => {
          if (!rootElement.querySelector('.focus label')) {
            return;
          }
          const dataItemId = rootElement.querySelector('.focus label').dataset
            .id;
          const radioElement = rootElement.querySelector('.focus input');
          onApnItemDefaultSet(
            serviceIdNum,
            apnType,
            radioElement,
            itemsOBJ[dataItemId]
          );
          SettingsSoftkey.hide();
          returnTop();
        }
      };
      //3.右边：编辑+删除（+重置）
      const softkeyOption = [
        {

          l10nId: 'edit',
          priority: 7,

            focusId = getFocusPos(rootElement);
            const dataItemId = rootElement.querySelector('.focus label').dataset
              .id;
            onApnItemEdit(itemsOBJ[dataItemId]);
          }

                }
              },
              cancel: {

              confirm: {
                l10nId: 'delete-apn',
                priority: 3,
                callback: () => {
                  if (focusItem.apn.deletedCpApn === false) {
                    focusItem.apn.deletedCpApn = true;

                  } else {
                    ApnSettingsManager.removeApn(serviceIdNum, focusItem.id)
                      .then(() => {
                        onApnDelete(rootElement, focusItem.apn.carrier);
                      })
                      .then(() => {
                        updateUI();
                      });
                  }
                }

            };
            DialogHelper.show(dialogConfig);
          }
        }, //如果没有定制开发添加下面reset，可以去掉此逗号 
 
        //【开发方案】添加 reset 功能，重置APN

      const softkeyParams = {

        items: []
      };
      let focusLabel = rootElement.querySelector('.focus label');
      if (!focusLabel) {
        focusLabel = rootElement.querySelector('li label');
      }
      softkeyParams.items.push(softkeyAdd);
 
      //最终判断菜单用的常量
      if (focusLabel) {
        softkeyParams.items.push(softkeySelect);
        const dataItemId = focusLabel.dataset.id;
        const focusItem = itemsOBJ[dataItemId];
        if (

    //更新菜单配置

      SettingsSoftkey.show();

    return SettingsPanel({
    }); //SettingsPanel
 
  }; //createApnSettingsPanel.
});

方案介绍

在功能函数 registerSoftkey 中自定义菜单选项常量 softkeyOption_custom，然后最后通过判断你选择不同的菜单内容项。

      const softkeyOption_custom = [
          {
              name: 'More Info',
              l10nId: 'more-info',
              priority: 7,
              method: function() {
                  focusId = getFocusPos(rootElement);
                  const dataItemId=rootElement.querySelector('.focus label').dataset.id;
                  onApnItemMoreInfo(itemsOBJ[dataItemId]);
              }
          }
      ];
 
      if (focusLabel) {
        softkeyParams.items.push(softkeySelect);
        const dataItemId = focusLabel.dataset.id;
        const focusItem = itemsOBJ[dataItemId];
        if(ApnUtils.isOpSim()) { //自定义接口判断 , ApnUtils工具类自定义在js/module中
			softkeyParams.items.push.apply(softkeyParams.items, softkeyOption_custom );
			dump('apn_list/panel, OP require to remove Reset menu.');
        } else {
            softkeyParams.items.push.apply(softkeyParams.items, softkeyOption);
        }
      }

apn_list/panel.js 导入个工具类可用如下方式：

const ApnUtils = require('modules/apn/apn_utils');

apn_utils.js

Note：新增接口的时候一定要同步加到return中，否则报错找不到函数：

          } else if (mccmnc === '31420') {
              return true;
          }
        }
      }
    }
	return false;
  }
                    
  return {
    getOperatorCode,

    isMatchedApn,
    sortByCategory,
    clone,
    isOpSim
  };
});

三、调试Debug

push替换settings应用文件application.zip到设备快速调试。

如果是kaios全编项目，则settings产物在 gaia/profile/webapps 目录下。
