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<b)javascript

（这需求仍是很简单的么 ）（然而排序结果并非想象的那样）java

["吃","安","的","不"]web

按照需求应该是abcd字母拼音排序数组

["安","不","吃","的",]svg

结果是spa

["的","安","吃","不"]code

升级->出现汉字排序xml

最开始想法 使用字符串比对 : sort((a,b)=>a<b)排序

// 并非咱们想要的 拼音顺序 ["的","安","吃","不","d","b","a","=","-"," "] // 并非咱们想要的 拼音顺序 ["的","安","吃","不","d","b","a","=","-"," "]

解决：localeCompare() （兼容需考虑）token

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"] // 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) 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)

// 并非咱们想要的 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"] // 并非咱们想要的 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"]
