如何加载JSON数据以与select2插件一起使用它

Question

我想为我的项目使用select2插件.我按照这个例子,但它对我不起作用.

JSON输出:

[
    {"ime":"BioPlex TM"},
    {"ime":"Aegis sym agrilla"},
    {"ime":"Aegis sym irriga"},
    {"ime":"Aegis sym microgranulo"},
    {"ime":"Aegis sym pastiglia"},
    {"ime":"Agroblen 15816+3MgO"},
    {"ime":"Agroblen 18816+3MgO"},
    {"ime":"Agrobor 15 HU"},
    {"ime":"Agrocal (Ca + Mg)"},
    {"ime":"Agrocal (Ca)"},
    {"ime":"Agrogold"},
    {"ime":"Agroleaf Power 12525+ME"},
    {"ime":"Agroleaf Power 151031+ME"},
    {"ime":"Agroleaf Power 202020+ME"},
    {"ime":"Agroleaf Power 311111+ME"},
    {"ime":"Agroleaf Power Ca"},
    {"ime":"Agrolution 14714+14 CaO+ME"},
    {"ime":"Agrovapno dolomitno"},
    {"ime":"Agrovit HSF"},
    {"ime":"Agrovit P"},
    {"ime":"Agrozin 32 T"},
    {"ime":"Albatros Hydro"},
    {"ime":"Albatros Sprint"},
    {"ime":"Albatros Standard"},
    {"ime":"Albatros Universal"},
    {"ime":"Algaren"},
    {"ime":"AlgoVital ? Plus"},
    {"ime":"Amalgerol PREMIUM"},
    {"ime":"Amcolon \/ Novalon"},
    {"ime":"Amcopaste"},
    {"ime":"Aminosprint N8"},
    {"ime":"AminoVital"},
    {"ime":"Ammonium nitrate 33.5%"},
    {"ime":"Ammonium nitrate with calcium sulfate"},
    {"ime":"Ammonium sulfate"}
]

脚本:

function formatDjubrivo(data) {
    return data;
}
function formatDjubrivo1(data) {
    return data.ime;

$( "#inputs" ).change(function() {
    console.log('prolazi klik');
    var t = $( this ).val();
    console.log(t);
    if (t=='djubrivo') {
       console.log('prolazi klik if');
       $('#stavka').select2({
          ajax: {
             dataType : "json",
             url      : "djubrivo.php",
             results  : function (data) {
                 return {results: data};
             }
          },
          formatResult : formatDjubrivo
       });
    }else {
       console.log('nije djubrivo');
    }
});

HTML:

<div class="col-md-2" style="padding-right:0px;">
    Vrsta Inputa
    <select id="inputs" name="inputs" class="form-control js-example-responsive">
        <option value="djubrivo">djubrivo</option>
        <option value="pesticidi">pesticidi</option>
        <option value="kultura">kultura</option>
        <option value="voda">voda</option>
    </select>
</div>

<div class="col-md-2" style="padding-right:0px;">
    Stavka
    <input id="stavka" name="stavka" class="form-control js-example-responsive">
</div>

这是我使用console.log以下代码测试代码时的结果:

Select2:AJAX结果未results在响应键中返回数组.

我哪里弄错了？

Answer 1

您似乎正在使用Select2 4.0,包括您提供给示例的链接以及您收到的错误消息.但是,您的代码是为以前版本的Select2编写的.

如果您想继续使用Select2 4.0:

(1)将resultsajax选项更改为processResults.

(2)更改processResults函数,results使它返回的对象的属性是一个对象数组,其中每个对象都有一个id和一个text属性.一种方法是使用该$.map()函数从ajax调用返回的数组创建一个新数组.

processResults: function (data) {
    return {
        results: $.map(data, function(obj) {
            return { id: obj.ime, text: obj.ime };
        })
    };
}

你也可以摆脱这个formatResult选择.

(3)使用<select>元素而不是<input>元素.

<select id="stavka" name="stavka" class="form-control js-example-responsive"></select>

尝试这个 ：

$.getJSON("djubrivo.php", function (json) {
      $("#inputs").select2({
         data: json,
         width: "180px"
      });
 });

示例 json ：

    {
      results:{
        {id:0,text:"enhancement"},
        {id:1,text:"bug"},
        {id:2,text:"duplicate"},
        {id:3,text:"invalid"},
        {id:4,text:"wontfix"}
      }
    }
