Javascript 使用带有$GetJson函数的传单搜索插件

javascript json leaflet

Javascript 使用带有$GetJson函数的传单搜索插件,javascript,json,leaflet,Javascript,Json,Leaflet,我想让我的传单搜索插件为地图上附加的外部.json文件工作为了向您阐明我想要实现的目标，我将为您提供两个代码示例： 1-来自脱机文件，附带geoJSON js文件 2-来自localhost，其中.json文件已由$GetJson函数获取第一个代码如下所示： var sitis = L.geoJSON(sitec, { pointToLayer: function (feature, latlng) { feature.properties.myKey = feature.propertie

我想让我的传单搜索插件为地图上附加的外部.json文件工作

为了向您阐明我想要实现的目标，我将为您提供两个代码示例：

1-来自脱机文件，附带geoJSON js文件 2-来自localhost，其中.json文件已由$GetJson函数获取

第一个代码如下所示：

var sitis = L.geoJSON(sitec, {
pointToLayer: function (feature, latlng) {
feature.properties.myKey = feature.properties.Title + ', ' + feature.properties.Head
    return L.circleMarker(latlng, geojsonMarkerOptions);
},
    onEachFeature: function (feature, layer) {
        layer.bindPopup("<h1><u><font color='red'>"+feature.properties.Title+"</h1></u></font><h2>Address: "+feature.properties.Head+"</h2><p>"+feature.properties.Description+"</p><p> Website:"+feature.properties.URL+"</p><br><center><a href='file:///Z:\\Fixed Line\\Design & Build\\2.

}

    }).addTo(map);

// layer 1
  $.getJSON(url1, function(data) {

    job = L.geoJson(data, {

        pointToLayer: function(feature, latlng) {

            return L.circleMarker(latlng, {
            radius:6,
            opacity: .5,
            //color: "#000",
            color:getColor(feature.properties.League),
            fillColor:  getColor(feature.properties.League),
            fillOpacity: 0.8

            });  //.bindTooltip(feature.properties.Name);
        },

            onEachFeature: function (feature, layer) {
                layer._leaflet_id = feature.properties.Owner;


                var popupContent = "<p>The <b>" +
                feature.properties.Owner + "</b> play here,</br> They are in the " +
                feature.properties.League + "</br>" +
                '<a href="'+ feature.properties.Website +'" target="_blank">Website</a></p>' ;

                if (feature.properties && feature.properties.popupContent) {
                    popupContent += feature.properties.popupContent;
                }
                    layer.bindPopup(popupContent);

            }

            }).addTo(map);
    });
//END Layer1

var url1 = "Peterborough.json"; //.json file, where we fetch the data from
var job; //setting variable for our layer

$.getJSON(url1, function(data) {
job = L.geoJson(data, {

    pointToLayer: function(feature, latlng) {

        return L.circleMarker(latlng, {
        radius:6,
        opacity: .5,
        //color: "#000",
        color:getColor(feature.properties.League),
        fillColor:  getColor(feature.properties.League),
        fillOpacity: 0.8

        });  //.bindTooltip(feature.properties.Name);
    },

        onEachFeature: function (feature, layer) {
            layer._leaflet_id = feature.properties.Owner;


            var popupContent = "<p>The <b>" +
            feature.properties.Owner + "</b> play here,</br> They are in the " +
            feature.properties.League + "</br>" +
            '<a href="'+ feature.properties.Directory +'" target="_blank">Local 
 directory</a></p>' ;

            if (feature.properties && feature.properties.popupContent) {
                popupContent += feature.properties.popupContent;
            }
                layer.bindPopup(popupContent);

        }

        }).addData(data).addTo(map); // adding the layer fetched from .json file to the map
        //---------------adding the leaflet-search plugin inside the $GetJSON function ----------
        L.control.search({
layer: job,
initial: false,
propertyName: 'Owner', // Specify which property is searched into.
zoom: 18,
position: 'topleft'
  }).addTo(map);

}); // $GetJSON function enclosure for this layer

但是在第二段代码中有一个问题

我的初始数据如下所示：

var sitis = L.geoJSON(sitec, {
pointToLayer: function (feature, latlng) {
feature.properties.myKey = feature.properties.Title + ', ' + feature.properties.Head
    return L.circleMarker(latlng, geojsonMarkerOptions);
},
    onEachFeature: function (feature, layer) {
        layer.bindPopup("<h1><u><font color='red'>"+feature.properties.Title+"</h1></u></font><h2>Address: "+feature.properties.Head+"</h2><p>"+feature.properties.Description+"</p><p> Website:"+feature.properties.URL+"</p><br><center><a href='file:///Z:\\Fixed Line\\Design & Build\\2.

}

    }).addTo(map);

// layer 1
  $.getJSON(url1, function(data) {

    job = L.geoJson(data, {

        pointToLayer: function(feature, latlng) {

            return L.circleMarker(latlng, {
            radius:6,
            opacity: .5,
            //color: "#000",
            color:getColor(feature.properties.League),
            fillColor:  getColor(feature.properties.League),
            fillOpacity: 0.8

            });  //.bindTooltip(feature.properties.Name);
        },

            onEachFeature: function (feature, layer) {
                layer._leaflet_id = feature.properties.Owner;


                var popupContent = "<p>The <b>" +
                feature.properties.Owner + "</b> play here,</br> They are in the " +
                feature.properties.League + "</br>" +
                '<a href="'+ feature.properties.Website +'" target="_blank">Website</a></p>' ;

                if (feature.properties && feature.properties.popupContent) {
                    popupContent += feature.properties.popupContent;
                }
                    layer.bindPopup(popupContent);

            }

            }).addTo(map);
    });
//END Layer1

var url1 = "Peterborough.json"; //.json file, where we fetch the data from
var job; //setting variable for our layer

$.getJSON(url1, function(data) {
job = L.geoJson(data, {

    pointToLayer: function(feature, latlng) {

        return L.circleMarker(latlng, {
        radius:6,
        opacity: .5,
        //color: "#000",
        color:getColor(feature.properties.League),
        fillColor:  getColor(feature.properties.League),
        fillOpacity: 0.8

        });  //.bindTooltip(feature.properties.Name);
    },

        onEachFeature: function (feature, layer) {
            layer._leaflet_id = feature.properties.Owner;


            var popupContent = "<p>The <b>" +
            feature.properties.Owner + "</b> play here,</br> They are in the " +
            feature.properties.League + "</br>" +
            '<a href="'+ feature.properties.Directory +'" target="_blank">Local 
 directory</a></p>' ;

            if (feature.properties && feature.properties.popupContent) {
                popupContent += feature.properties.popupContent;
            }
                layer.bindPopup(popupContent);

        }

        }).addData(data).addTo(map); // adding the layer fetched from .json file to the map
        //---------------adding the leaflet-search plugin inside the $GetJSON function ----------
        L.control.search({
layer: job,
initial: false,
propertyName: 'Owner', // Specify which property is searched into.
zoom: 18,
position: 'topleft'
  }).addTo(map);

}); // $GetJSON function enclosure for this layer

}) .addTo（地图）

但是没有结果。我的控制台显示：

 Uncaught TypeError: Cannot read property '_leaflet_id' of undefined
at u (leaflet.js:5)
at i.getLayerId (leaflet.js:5)
at i.addLayer (leaflet.js:5)
at initialize (leaflet.js:5)
at new i (leaflet.js:5)
at Object.t.layerGroup (leaflet.js:5)
at (index):659

我真的不知道发生了什么。老实说，我找到了解决方案，它可以获取.json bvia Ajax和JQuery

但我已经通过$GetJSON函数从.json获取了数据

此处提供了另一个选项：

但一旦我将其实现到我的代码中，比如：

var searchControl = new L.Control.Search({
layer: job,
propertyName: 'Owner',
circleLocation: false

}))

我只有一个放大镜，但找不到

我的控制台说：

leaflet-search.js:774 Uncaught TypeError: Cannot read property 'call' of 
undefined
at i._fillRecordsCache (leaflet-search.js:774)
at leaflet-search.js:720

我指的是：

传单-search.js 774

 this._curReq = this._retrieveData.call(this, inputText, function(data) {

即使我从

函数（e）

更改为

[！[function（data）][1]][1]

结果仍然相同

是否可以通过$getJSON函数使传单搜索控制台对外部.json文件有效？

解决方案之一是将

L.search.Control

放在

$getJSON

函数中，该函数在主脚本中看起来像一个单独的“主体”。就解决方案而言，代码应如下所示：

var sitis = L.geoJSON(sitec, {
