我正在尝试使用地名数据填充 select2 元素。我有一个定义的FormatSelection方法,但选择了一个项目时不会触发。
这是 HTML 元素:
<input id="location" size="30" type="text">
Select2 与格式函数的绑定:
function locationFormatResult(location) {
var markup = "<table class='location-result'><tr>";
if (location.countryCode !== undefined) {
markup += "<td class='flag-image'><img src='http://www.geonames.org/flags/x/" + location.countryCode.toLowerCase() + ".gif' /></td>";
}
markup += "<td class='location-info'>";
markup += "<div class='location-name'>" + location.name + ", " + location.adminName1 + ", " + location.countryName + "</div>";
markup += "</td></tr></table>";
return markup;
}
function locationFormatSelection(location) {
return location.name + ", " + location.adminName1 + ", " + location.countryName;
}
$(function () {
$('#location').select2({
placeholder: 'Location',
allowClear: true,
width: '260px',
minimumInputLength: 2,
ajax: {
url: 'http://ws.geonames.org/searchJSON',
dataType: 'jsonp',
data: function (term) {
return {
featureClass: 'P',
q: term
};
},
results: function (data) {
return {
results: data.geonames
};
}
},
formatResult: locationFormatResult,
formatSelection: locationFormatSelection,
dropdownCssClass: "bigdrop"
});
});

为什么选择一个项目不起作用?
