拼音排序：
var arr = [{ a: 1, b: "我" }, { a: 1, b: "是" }, { a: 1, b: "帅" }, { a: 1, b: "哥" }, { a: 1, b: "你" }, { a: 1, b: "服" }, { a: 1, b: "不" }];arr.sort(function compareFunction(param1, param2) {return param1.b.localeCompare(param2.b,"zh");}
);// 结果为：[{a: 1, b: "不"},{a: 1, b: "服"},{a: 1, b: "哥"},{a: 1, b: "你"},{a: 1, b: "是"},{a: 1, b: "帅"},{a: 1, b: "我"}]拼音排序并按字母分类：
function pySegSort(arr,empty) {if(!String.prototype.localeCompare)return null;var letters = "*abcdefghjklmnopqrstwxyz".split('');var zh = "阿八嚓哒妸发旮哈讥咔垃痳拏噢妑七呥扨它穵夕丫帀".split('');var segs = [];var curr;$.each(letters, function(i){curr = {letter: this, data:[]};$.each(arr, function() {if((!zh[i-1] || zh[i-1].localeCompare(this,"zh") <= 0) && this.localeCompare(zh[i],"zh") == -1) {curr.data.push(this);}});if(empty || curr.data.length) {segs.push(curr);curr.data.sort(function(a,b){return a.localeCompare(b,"zh");});}});return segs;
}JSON.stringify(pySegSort(["我","不","懂","爱","啊","按","已","呀","选","县"]));// 结果:
"[{"letter":"a","data":["啊","爱","按"]},{"letter":"b","data":["不"]},{"letter":"d","data":["懂"]},{"letter":"w","data":["我"]},{"letter":"x","data":["县","选"]},{"letter":"y","data":["呀","已"]}
