クリアマーカーレイヤー（リーフレット）

Question

リーフレットライブラリーを使用していて、次の問題が発生しました。 マップを生成するにはボタンのクリックでマップ関数を呼び出しています。 したがって、各generatemap関数呼び出しでは、あらかじめ生成されたマーカーをクリアします。

function generatefilterrecord(orgid,defservice,defavail,defowner,defhealthfacility) { 
 

 
    $("#content1").hide(); 
 
    $("#map1").show(); 
 

 
    $("#mapA1").hide(); 
 
    $("#footer").hide(); 
 
    jQuery('#sel').html(''); 
 
    $(".w3-card-4").remove(); 
 

 

 
    var addressjoin=[],ouid=[],availspecialitiesjoin,availspecialities=[],avaialabilityjoin,name=[],address=[],pincode=[],village=[],mobile=[],special=[],notspecial=[],hfacilities=[],nothfacilities=[],schemes=[],notschemes=[],contactpname=[],contactpnumber=[]; 
 
    var toAdd,spec=[],email=[],specialjoin,notspecialjoin,notspec=[],owner=[],notowner=[],hfacilitiesjoin,nothfacilitiesjoin,schemesjoin,notschemesjoin,hfschemes=[],nothfschemes=[]; 
 
    var healthfac="",ownership=[],availspecialiti=[]; 
 
    var arrayMap = [];latitude=[];longitude=[];

ここ

マップ決して生成しますが、私は）（marker.clearLayersを削除する場合。問題はそれがすべての結果を追加するので、私は最後に生成されたマーカーをクリアしたいです。

Answer 1

代わりのマップに直接マーカーを追加して、いつでも好きなときに、あなたがclearLayers方法

var layerGroup = L.layerGroup().addTo(map); 

// create markers 
L.marker().addTo(layerGroup); 

// remove all the markers in one go 
layerGroup.clearLayers();
