我正在使用Select2作为我的下拉样式。然后输出选项,如
<option value="001,100">Option 001</option>
<option value="002,200">Option 002</option>
<option value="003,300">Option 003</option>
我想要做的是当有人点击其中一个选项时,会触发jQuery操作loadMap(coords)
。所以基本上如果有人选择第一个选项,它应该触发loadMap(001,100)
。
我将如何实现这一目标? https://select2.github.io/examples.html的文档说:
&#34; select2:只要选择了结果就会触发选择。&#34;
var $eventLog = $(".js-event-log");
var $eventSelect = $(".js-example-events");
$eventSelect.on("select2:select", function (e) { log("select2:select", e); });
但是我如何才能启动jQuery操作呢?
这是我的标记:
<div class="form-group">
<select class="map form-control" name="map"></select>
</div>
<script>
$( document ).ready(function() {
$( ".map" ).select2({
ajax: {
url: "https://www.url.com/query_maps.php",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term
};
},
processResults: function (data) {
// parse the results into the format expected by Select2.
// since we are using custom formatting functions we do not need to
// alter the remote JSON data
return {
results: data
};
},
cache: true
},
minimumInputLength: 2,
placeholder: "Select your map"
});
});
</script>

$("#map").select2();
$("#map").on('change', function(){
var selected = $(this).val();
loadMap(selected);
});
function loadMap(val){
alert("You have selected "+val);
}
