如何加载 JSON 数据以与 select2 插件一起使用
How to load JSON data to use it with select2 plugin
我想为我的项目使用 select2 插件。我遵循了 this 示例,但它对我不起作用。
JSON 输出 :
[

]
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
:
测试我的代码时的结果
Select2: The AJAX results did not return an array in the results
key of the response.
我哪里弄错了?
从您提供给示例的 link 和您收到的错误消息来看,您似乎正在使用 Select2 4.0。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results
ajax选项改为processResults
.
(2) 改变processResults
函数,使returns对象的results
属性是一个对象数组,其中每个对象都有一个id
和 text
属性。一种方法是使用 $.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 };
})
};
}
您也可以去掉 formatResult
选项。
(3) 使用 <select>
元素,而不是 <input>
元素。
<select id="stavka" name="stavka" class="form-control js-example-responsive"></select>
试试这个:
$.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"}
}
}
