Js实现中文排序(解决node环境下不支持汉字排序)

1. 汉字所对应的拼音 省略字典（网上找或者联系做者）

   const PinYin = {
            a: '\u554a\u963f\u9515',
            ai:
        }

2. 在字典中搜索

   function arraySearch(zh) {
        for (let name in PinYin) {
            if (PinYin[name].indexOf(zh) != -1) {
                return name
            }
        }
        return ''
    }

3. 汉字转拼音

   function ConvertPinyin(str) {
        const reg = new RegExp(/[\u4e00-\u9fa5]/) //匹配汉字
        let ary = str.split('')
        let pinyin = ary.reduce((pre, item) => {
            if (reg.test(item)) {
                let name = arraySearch(item)
                pre += name
            } else {
                pre += item
            }
            return pre
        }, '')
        let letter = pinyin.slice(0, 1)
        return { pinyin, letter }
    }

4. 排序

   const pySegSort = (arr, keyword) => {
        if (!String.prototype.localeCompare) return null
        let obj = {}
        arr.forEach(item => {
            if (keyword) {
                const { pinyin, letter } = ConvertPinyin(item[keyword])
                obj[letter]
                    ? obj[letter].push({ ...item, pinyin, letter })
                    : (obj[letter] = [{ ...item, pinyin, letter }])
            } else {
                const { pinyin, letter } = ConvertPinyin(item)
                obj[letter]
                ? obj[letter].push({ zh: item, pinyin, letter })
                : (obj[letter] = [{ zh: item, pinyin, letter }])
            }
        })
        let data=Object.keys(obj).sort((a,b)=>a.localeCompare(b)).map(item=>{
            let data =obj[item]
            data.sort((a,b)=>a.pinyin.localeCompare(b.pinyin))
            return {title:item,data}
        })
        return data
    }

5. 测试

   let a = ["保定","西安","澳门","台湾",'江苏',"承德","抚顺","海南",'西藏','天津',"宝鸡","上海","北京"]
   pySegSort(a)

   [
        {   title: 'a', data: [{ zh: '澳门', pinyin: 'aomen', letter: 'a' }] },
        {
            title: 'b',
            data: [
                { zh: '保定', pinyin: 'baoding', letter: 'b' },
                { zh: '宝鸡', pinyin: 'baoji', letter: 'b' },
                { zh: '北京', pinyin: 'beijing', letter: 'b' },
            ],
        },
        { title: 'c', data: [{ zh: '承德', pinyin: 'chengde', letter: 'c' }] },
        { title: 'f', data: [{ zh: '抚顺', pinyin: 'fushun', letter: 'f' }] },
        { title: 'h', data: [{ zh: '海南', pinyin: 'hainan', letter: 'h' }] },
        { title: 'j', data: [{ zh: '江苏', pinyin: 'jiangsu', letter: 'j' }] },
        { title: 's', data: [{ zh: '上海', pinyin: 'shanghai', letter: 's' }] },
        {
            title: 't',
            data: [
                { zh: '台湾', pinyin: 'taiwan', letter: 't' },
                { zh: '天津', pinyin: 'tianjin', letter: 't' },
            ],
        },
        {
            title: 'x',
            data: [
                { zh: '西安', pinyin: 'xian', letter: 'x' },
                { zh: '西藏', pinyin: 'xicang', letter: 'x' },
            ],
        },
    ]
