jQuery自动完成中的未定义结果 [英] Undefined Results in jQuery Autocomplete

问题描述

因此，我正在运行最新版本的jQuery和UI. 我正在使用基本的自动完成调用，并返回有效的JSON(通过JSONLint验证).

So I've got the latest versions of jQuery and UI running. I'm using the basic autocomplete invocation and returning valid JSON (validated via JSONLint).

    $("input#cust_id").autocomplete({
        source: yoda.app.base + "/assets/cfc/util/autocomplete.cfc?method=cust",
        minLength: 2,
        select: function(event, ui) {
            log(ui.item ? ("Selected: " + ui.item.value + " aka " + ui.item.id) : "Nothing selected, input was " + this.value);
        }
    });

返回数组的value和label元素在列表中均显示为undefined. 我可以观看通过Firebug返回的结果，那里的JSON也正确.此外，虽然列表只说未定义"，但确实说的次数与JSON中返回的记录的次数相同.

Both the value and label elements of the returned array show up in the list as undefined. I can watch the results returned via Firebug and the JSON is correct there as well. Also, while the list only says "undefined" it does say that the same number of times as records returned in JSON.

[{"VALUE":"custid1","LABEL":"My Customer Name 1"},{"VALUE":"custname2","LABEL":"My customer name 2"}]

推荐答案

您的JSON需要看起来像这样:

Your JSON needs to look like this:

[{value:"custid1",label:"My Customer Name 1"},{value:"custname2",label:"My customer name 2"}]

因为键区分大小写:

var obj = {"hello" : "foo"};
alert(obj.HELLO); // undefined
alert(obj.hello); // foo
