我有一个 JSON 数组，如下所示：

[{"country":"FR","id":2,"latitude":-34.27175846153846,"longitude":54.16125384615385,"postcode":"00000","region1":"DOM-TOM","region2":"Terres australes et antarctiques","region3":"Crozet","region4":"","version":null},{"country":"FR","id":3,"latitude":46.203635000000006,"longitude":5.20772,"postcode":"01000","region1":"Rhône-Alpes","region2":"Ain","region3":"Bourg-en-Bresse","region4":"Bourg-en-Bresse","version":null}, ...

我正在尝试将此数组用作 JQuery 自动完成的源。这是我尝试的：

$(function() {
    $("#postcode").autocomplete({
        source : function(request, response) {
            var firstChars = $("#postcode").attr("value");
            $.getJSON("/kadjoukor/geolocations", {
                postcodeFirstChars : firstChars
            }, function(data) {
                console.log(data.postcode);
                response(data.postcode);
            });
        },
        minLength : 3,
    });
});

这是html：

<input type="text" name="member.geolocation.postcode" value="" id="postcode" placeholder="Code postal" />

我想显示这个 JSon 数组中的邮政编码变量。有人可以帮忙吗？

您应该将结果数组转换为标签值对。在你的情况下可以像

source : function(request, response) {
        var firstChars = $("#postcode").attr("value");
        $.getJSON("/kadjoukor/geolocations", {
            postcodeFirstChars : firstChars
        }, function(data) {
            console.log(data.postcode);
            response($.map(data, function (item) {
                    return {
                        label: item.postcode,
                        value: item.postcode
                    };
                }));
        });
    },
