内部函数时，Json只返回最后一个元素

Question

我有一个代码从数据库中提取json，然后将其输出到地图上。

我遇到的问题是，当我在console.log中显示来自服务器的数据时，它显示了所有但是如果我在一个函数内而不是在“root”中的console.log它只显示json中的最后一个元素。我正在使用for (var i = 0; i < $data.length; i++))将每个json元素显示为“唯一”。

代码中的问题在于：

$( "#filter-gratis" ).click(function() {
                    console.log($geoJson[0].properties.place);
                    all.className = '';
                    this.className = 'active';
                    // The setFilter function takes a GeoJSON feature object
                    // and returns true to show it or false to hide it.
                    console.log("works");
                    $myLayer.setFilter(function(f) {
                        return f.properties['male'] < '1';
                    });
                    return false;
                });

如果我在点击内部console.log($geoJson[0].properties.place);，它只显示json中的最后一个元素。但是，如果我在外面做，（在它上面）就行了。

这是我的代码：

       $.ajax({     
            url: 'http://hotell.difi.no/api/json/bergen/dokart?',     
            dataType: 'json',     
            async: false,
            success: processJSON 
        });


        function processJSON(data) {
            $data = data.entries;

            for (var i = 0; i < $data.length; i++) {


                // Endre "null" til 0 og de som har pris med "kr"
                if($data[i].pris == "NULL"){
                    $data[i].pris = "GRATIS";
                }else if($data[i].pris >= 0){
                    $data[i].pris = $data[i].pris + "kr";
                }

                // Om den er stengt i helgen
                if($data[i].tid_lordag == "NULL"){
                    $data[i].tid_lordag = "Stengt";
                }
                if($data[i].tid_sondag == "NULL"){
                    $data[i].tid_sondag = "Stengt";
                }

                // Om den er åpen
                if($data[i].tid_hverdag == "ALL" && $data[i].tid_lordag == "ALL" && $data[i].tid_sondag == "ALL"){
                    $data[i].tid_hverdag = "Alltid åpen"
                    $data[i].tid_lordag = []

有什么建议吗？ 谢谢！
