js文字排序的方法

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"]}
]"
