使用osm地图，javascript代码和OpenLayers库进行地理编码

Question

I want to Geocoding using OSM map, javascript code and OpenLayers library. 我想使用OSM地图，javascript代码和OpenLayers库进行地址解析。 .But I do not know what library I should use or what code to write.please guide me. 但是我不知道我应该使用哪个库或编写什么代码。请指导我。 Thanks I want to make changes to the code below to add Geocoding. 谢谢，我想对以下代码进行更改以添加地址解析。

          });

If you're looking for controls to let the user search places on your map, have a look at this example with Nominatim or this with Photon API . 如果您正在寻找让用户在地图上搜索位置的控件，请使用Nominatim或使用Photon API的示例。 Just create a control and add it to the map. 只需创建一个控件并将其添加到地图即可。 Then do something when a place is selected (center the map): 然后在选择地点后做点什么（使地图居中）：

// Set the search control 
var search = new ol.control.SearchNominatim ({
// or: = new ol.control.SearchPhoton({
  lan: 'en',
  position: true    // Search, with priority to geo position
});
map.addControl (search);

// Center map when destination is selected
search.on('select', function(e) {
  map.getView().animate({
    center: e.coordinate,
    zoom: Math.max (map.getView().getZoom(),16)
});

If you want to geocode a bulk of addresses, look at API used by the example and their implementation in the lib. 如果要对大量地址进行地理编码，请查看示例使用的API及其在lib中的实现。
