js数组汉字排序

最初思路：数组内容排序 sort -> 字符串排序 sort((a,b)=>a

（这需求还是很简单的么 ）（然而排序结果并不是想象的那样）

["吃","安","的","不"]

按照需求应该是abcd字母拼音排序

["安","不","吃","的",]

结果是

["的","安","吃","不"]

升级->出现汉字排序

最开始想法 使用字符串比对 : sort((a,b)=>a

// 并不是我们想要的 拼音顺序
["的","安","吃","不","d","b","a","=","-"," "] 

解决：localeCompare() （兼容需考虑）

使用str1.localeCompare(str2);sort((a,b)=>a.localeCompare(b))

// 拼音顺序  字符在前 汉字拼音顺序紧随 字母在后
[" ","-","=","安","不","吃","的","a","b","d"]

var x=['-','=',' ','安','a','不','b','吃','d','的'];

var s1=x.concat([]).sort((a,b)=>a<b);

var s2=x.concat([]).sort((a,b)=>a.localeCompare(b));

console.log(s1,s2)

// 并不是我们想要的 拼音顺序
["的","安","吃","不","d","b","a","=","-"," "] 

// 拼音顺序  字符在前 汉字拼音顺序紧随 字母在后
[" ","-","=","安","不","吃","的","a","b","d"]
