Question

我想通过Value data.FuelState对我的JSON表进行排序。

不幸的是，它转回来了，data.sort没有功能。怎么了？基础排序功能是否正确？

<!DOCTYPE html>
<html>
<head>
//..//
</head>

<body>
<script src="js/bootstrap.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
    function callJSON() {
        setTimeout(function () {
            $.getJSON('./url.php', function(data) {
                $("#usertable").empty();
                data.sort(function(a,b) {
                    return parseFloat(b.fuelState) - parseFloat(a.fuelState);
                });

                var cars = data.rec.vehicles.vehicles;
                $.each(cars, function(key, data){
                    //..//
                    $('#usertable').append(
                        function() {
                            return "<tr class="+farbe+">" +
                                   "<td><span class='glyphicon glyphicon-user'></span> "+data.carName+"</td>" +
                                   //..//
                                   "<tr>"; 
                        }
                    );
                });
            }).always(callJSON);
        }, 2000);
    }
    $(callJSON);
});
</script>
</body>
</html>

JSON：

{"err":[],"msg":[],"state":null,"rec":{"vehicles":{"search_criteria":[{"auto":"N","group":"BMW","model":"BMW 1er "},{"auto":"N","group":"MINI","model":"MINI Cooper"},{"auto":"Y","group":"BMW","model":"BMW 1er "},{"auto":"Y","group":"MINI","model":"MINI Cooper"},{"auto":"N","group":"MINI","model":"MINI Clubman"},{"auto":"Y","group":"","model":" ActiveE "},{"auto":"N","group":"MINI","model":"MINI Cabrio"},{"auto":"Y","group":"BMW","model":"BMW X1 "},{"auto":"N","group":"BMW","model":"BMW X1 "},{"auto":"Y","group":"BMW","model":"BMW ActiveE "},{"auto":"N","group":"BMW","model":"BMW 1er Cabrio"},{"auto":"Y","group":"MINI","model":"MINI Clubman"},{"auto":"N","group":"MINI","model":"MINI Coup\u00e9"},{"auto":"Y","group":"MINI","model":"MINI Coup\u00e9"},{"auto":"N","group":"BMW","model":"BMW ActiveE "}],"statistics":[],"vehicles":[{"position":{"latitude":"48.055301944444","longitude":"11.607825833333","address":"Inselkammerstra\u00dfe 4, 82008 Unterhaching"},"vin":"WBAUD71000P448627","int":"12166478","auto":"N","carName":"Fausto","cit":"7586","color":"ALPINWEISS","fuelState":"21","fuelType":"DDE","group":"BMW","innerCleanliness":"CLEAN","licensePlate":"M  -N  2651","pgid":"0","model":"BMW 1er ","cd":"0","milliageMetricsName":"0","address":"Inselkammerstra\u00dfe 4, 82008 Unterhaching","personalName":"BMW 1er : Fausto","price":{"drive":"31","park":"10"}},{"position":{"latitude":"52.541172777778","longitude":"13.325585833333","address":"Saatwinkler Damm 15-17, 13627 Berlin"}

数据是你的完整JSON示例，它是一个包含其他数据的对象，而vihicle只是它的副本。

实际的汽车可以在

下找到

data.rect.vehicles.vehicles

（你指定汽车的那个）

因此将sort函数应用于汽车工作：

        var cars = data.rec.vehicles.vehicles;

        cars.sort(function(a,b) {
            return parseFloat(b.fuelState) - parseFloat(a.fuelState);
        });

按值排序JSON表
