Question

我想创建一个应用程序，帮助用户搜索城市中的美食场所，以便他们将来可以重新访问。这个应用程序是我第一个使用传单的有趣项目。我想做的是从数据库中制作简单的地图和加载标记，当用户从类别查询地点或在搜索栏中搜索时，只显示标记。我确实测试了JSFiddle中的索引pageand marker.js，但它只显示了map-wrap和搜索按钮，栏和类别。

Marker.js

//now map reference the global map declared in the first line
map=L.map('map').setView(true)

//marker development

L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
        attribution: 'Map data &copy;<a href="http://openstreetmap.org">OpenStreetMap</a>
     contributors,<a href="http://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>',
        maxZoom:18
     }).addTo(map);
    newMarkerGroup = new L.LayerGroup();
    map.on('click',addMarker);
 });

 //add group layer to map
 map.addLayer(search_group);

 //start to initiate adding marker
 function addMarker(e){
        // Add marker to map at click location; add popup window
        var newMarker = new L.marker(e.latlng).addTo(map);
    }

//create array
var marker= new Array();
function onMapClick(e){
    marker = new L.Marker(e.latlng,
{draggable: false});

//pushing items into array each by each and then add markers
function itemWrap(){
    for(i=0; i<items.length; i++){
        var LamMarker = new
    L.marker([items[i].lat,items[i].lon]);
        marker.push(LamMarker);
        map.addLayer(marker[i]);
    }
  }

 //create popup
  marker.bindPopup().openPopup();
  };

//add to map function with a popup that contains a link, which when clicked will have a popup of details and booking options
//this link will have as its id the latlng of the point
//this id will then be compared to when you click on one of your created markers 
map.on('click',function(e){
    var clickPositionMarker = L.marker([e.latlng.lat,e.latlng.lng],{icon:idMarker});
    clickArr.push(clickPositionMarker);
    mapLat = e.latlng.lat;
    mapLon = e.latlng.lng;
    clickPositionMarker.addTo(search_group).bindPopup().openPopup();

        L.marker(e.latlng).addTo(map)
            .bindPopup("You're within " + radius + " meters from this point").openPopup();

        L.circle(e.latlng, radius).addTo(map);

}

map.on('locationfound' , onLocationFound);

        //access it using markers[i]["id"]

我之前测试过index.html，当然我取消了L.marker的注释功能，它工作正常。弹出确实出现了。但是当我测试标记时，将评论放在L.marker上，只会出现map-wrap和其他css。 PLease帮助我，我确实审查了文档，测试了很多但没有出现。有人请帮助我，因为我真的很喜欢传单

Answer 1

您在new之前抛出L.marker，这不是此构造函数的格式。请注意m上的大小写差异。它必须是L.marker(options) }或new L.Marker(options)。您只需要new样式标记初始化L.Marker。见http://leafletjs.com/reference.html#marker

不显示传单地图和标记
