之前在其他地方看的zh字母分类列表不对，导致部分排序错误，特此记录
最重要的首拼汉字列表：阿八嚓耷妸发旮哈丌咔垃妈嗯喔妑七呥仨他穵夕丫帀
// sourceData: [{ id: restaurant.id, name: restaurant.name, available: true }, ...]function formatCommonData(sourceData) {let childrens = {};if (sourceData.length > 0) {const result = [];const defaultIndexes = [{ i: 9, data: ['i'] }, { i: 21, data: ['v', 'u'] }];const letters = '*abcdefghjklmnopqrstwxyz'.split('');const zh = '阿八嚓耷妸发旮哈丌咔垃妈嗯喔妑七呥仨他穵夕丫帀'.split('');const english = new RegExp('[A-Za-z]+');letters.forEach((letter, index) => {const current = { index: letter.toUpperCase(), childrens: [] };sourceData.forEach((item) => {let matched = false;if (english.test(item.name.substr(0, 1))) {matched = item.name.length > 0 && item.name.charAt(0).toUpperCase() === letter.toUpperCase();} else {// localeCompare需要加参数 'zh', 不然在英文环境下，无法正常工作matched = (!zh[index - 1] || zh[index - 1].localeCompare(item.name, 'zh') <= 0) && item.name.localeCompare(zh[index], 'zh') === -1;}if (matched) {current.childrens.push({ id: item.id, name: item.name, available: true });}});result.push(JSON.parse(JSON.stringify(current)));});defaultIndexes.forEach((index) => {index.data.forEach((x) => {const list = sourceData.filter((item) => item.name.length > 0 && item.name.charAt(0).toUpperCase() === x.toUpperCase());const temp = [];list.forEach((item) => {temp.push({ id: item.id, name: item.name, available: true });});result.splice(index.i, 0, { index: x.toUpperCase(), childrens: temp });});});const last = result.filter((item) => item.childrens.length > 0);last.forEach((item) => {item.childrens.sort((a, b) => a.name.localeCompare(b.name, 'zh'));});childrens = { indexes: last.map((x) => x.index), data: last };}return childrens;}
以上代码可以将 list转为以下格式
{indexes: ['B', 'H', 'L', 'S'],data: [{index: 'B',childrens: [{ id: 1, name: '北京安立路', availabel: true },{ id: 2, name: '北京百子湾', availabel: true }]},{index: 'H',childrens: [{ id: 3, name: '河北', availabel: true },{ id: 4, name: '河南', availabel: true }]},......]}
