javascript - 在 json 文件上使用嵌套数组自动完成

Question

这是我的json文件

"type": "FeatureCollection",
"name": "maps",
"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" } },
"features": [
{ "type": "Feature", "properties": { "IDLo": "1", "SoHieu": "1-1", "KyHieu": "C", "TenLo": "C1-1", "TenCty": "CMC Data Center"}, "geometry": { "type": "Polygon", "coordinates": [ [ [ 106.791800519464871, 10.854928689692501 ], [ 106.792069337729856, 10.855930098557222 ], [ 106.792653322236532, 10.855766231881775 ], [ 106.79231961680415, 10.854783029941672 ], [ 106.791800519464871, 10.854928689692501 ] ] ] } },

我想在 features.properties.TenCty 上自动完成搜索

这是javascript

jQuery(document).ready(function($) {
     $('#cty').autocomplete({
        source: function (request, response) {
        $.ajax({
            type: 'GET',
            url: "data/maps.json",
            dataType: 'json',
            data: request,
            success: function(data) {
                $.each(data.features, function(d){
                    response($.map(d.properties, function(item) {
                        console.log(item.TenCty);
                        return (item.TenCty);
                    }));
                })
            }
        }); 
   },  
   minLength: 2
  });
  });

但是我什么也得不到，控制台像这样 XHR finished loading: GET "http://localhost:81/blog/data/maps.json?term=fd"./p>

不知道哪里出错了。请帮忙。非常感谢。

Answer 1

基本上，您必须将 success 回调更新为:

success: function(data) {
   var result = $.each(data.features, function(d) {
       return (d.properties.TenCty);
   })
   response(result)
}

但是您可以重新访问 JQuery UI Autocomplete Remove JsonP code samples.
