在mapbox中过滤标记之后，弹出窗口不再起作用 [英] Popups no longer function after filtering markers in mapbox

问题描述

我已经从Mapbox中的外部geoJson文件中设置了功能，并按照 https://www.mapbox.com/mapbox.js/example/v1.0.0/custom-popup/

  var myLayer = L.mapbox.featureLayer（bldgData）.addTo（map）; 
 
 myLayer.eachLayer（function（layer）{
 
 //设置每个标记的弹出窗口
 var content =; 
 var props = 
 var imagePart =< img class ='popupPic'src ='images / thumbnails /+ props.filename +'>< / img>; 
 var infoPart =< h3 class ='popupInfo'>+ props.bldgName +< / h3>< p> + 
 props.architect +< br />+道具.year +< / p>; 
 content = imagePart + infoPart; 
 
 layer.bindPopup（content，{closeButton：false}）; 
}）; 
  

弹出窗口设置为在鼠标悬停时显示...

  myLayer.on（'mouseover'，function（e）{
 e.layer.closePopup（）; 
 e.layer.openPopup ）; 
}）; 
 $ b myLayer.on（'mouseout'，function（e）{
 e.layer.closePopup（）; 
}）; 
  

我还设置了过滤功能，以显示 https://www.mapbox.com/mapbox.js/example/v1.0.0/filtering -markers /

  function chooseBldg（）{
 var bldgs = document.getElementById（buildingTypeMenu ）。值; 
 
 if（bldgs ==all）{
 myLayer.setFilter（function（f）{return true;}）; 
 
 $ b $ else {
 myLayer.setFilter（function（f）{
 return f.properties ['buildingType'] === bldgs; 
 }）; 
 
 
 
 
 $ b 
当我第一次显示页面时，弹出窗口显示正确，并且筛选器正确选择要显示的标记的子集，但在筛选器被触发后，弹出窗口不再在鼠标悬停上显示。过滤器完成后，是否需要重新绑定弹出窗口（通过显式触发eachLayer函数或其他）？  
 
解决方案
重新绑定弹出窗口为我解决了这个问题。  
I have set up features from an external geoJson file in Mapbox and bound popups to these features following the example at https://www.mapbox.com/mapbox.js/example/v1.0.0/custom-popup/
var myLayer = L.mapbox.featureLayer(bldgData).addTo(map);

myLayer.eachLayer(function(layer) {

    // set up popup for each marker
    var content = "";
    var props = layer.feature.properties;
    var imagePart = "<img class='popupPic' src='images/thumbnails/" + props.filename + "' ></img>";
    var infoPart = "<h3 class='popupInfo'>" + props.bldgName + "</h3><p>" +
        props.architect + "<br />" + props.year + "</p>";
    content = imagePart + infoPart;

    layer.bindPopup(content, {closeButton: false});
});
The popups are set up to display on mouseover...
myLayer.on('mouseover', function(e) {
    e.layer.closePopup();
    e.layer.openPopup();
});

myLayer.on('mouseout', function(e) {
    e.layer.closePopup();
});
I have also set up filtering to display selected features following the example at https://www.mapbox.com/mapbox.js/example/v1.0.0/filtering-markers/
function chooseBldg(){
    var bldgs = document.getElementById("buildingTypeMenu").value;

    if(bldgs == "all") {
        myLayer.setFilter(function(f) {return true;});

    }
    else {
        myLayer.setFilter(function(f) {
            return f.properties['buildingType'] === bldgs;
        }); 
    }
}
The popups display correctly when I first display the page, and the filters correctly select the subset of markers to display, but after the filter has been triggered the popups no longer display on mouseover.  Do I need to rebind the popups (by explicitly triggering the eachLayer function or something) after the filter has been done? 
解决方案
Rebind popups solved this problem for me.
