自动完成搜索中的建议框没有出现

Question

I would like to create an auto-complete input box using the Photon service. What I tried to do was create an ajax request that would return the results. By entering a few letters of an address the Photon API should show me the results, as in the picture:

What I have writte is the following:

html

  <div class="frmSearch">
    <input type="text" id="search-box" placeholder="Country Name" />
    <div id="suggesstion-box"></div>
</div>

js

$("#search-box").keyup(function(){
        $.ajax({
        type: "GET",
        url: "http://photon.komoot.de/api/?q=" + $("#search-box").val(),

        beforeSend: function(){
            $("#search-box").css("background","#FFF url(LoaderIcon.gif) no-repeat 165px");
        },
        success: function(results){

       var aList = results.features;
       var aOptions = [];
       for (i=0; i < aList.length; i++) {
           optKey = aList[i].geometry.coordinates[0]+','+aList[i].geometry.coordinates[1];
           optLabel = aList[i].properties.name+', '+aList[i].properties.street+' '+aList[i].properties.housenumber+', '+
              aList[i].properties.city+', '+aList[i].properties.postcode;
           aOptions.push({
              "value": optKey,
              "label": optLabel
           });
       }

   

            $("#suggesstion-box").show();
            $("#suggesstion-box").html(aOptions);
            $("#search-box").css("background","#FFF");
        }
        });
    });

The API call works great but my suggestion box doesn't appear.. What I'm doing wrong?

You cannot add objects directly with html() function. You can only pass string

So you need to parse your object array as string

 $("#search-box").keyup(function() { $.ajax({ type: "GET", url: "https://photon.komoot.de/api/?q=" + $("#search-box").val(), beforeSend: function() { $("#search-box").css("background", "#FFF url(LoaderIcon.gif) no-repeat 165px"); }, success: function(results) { var aList = results.features; var aOptions = []; let htmlVal = ''; for (i = 0; i < aList.length; i++) { optKey = aList[i].geometry.coordinates[0] + ',' + aList[i].geometry.coordinates[1]; optLabel = aList[i].properties.name + ', ' + aList[i].properties.street + ' ' + aList[i].properties.housenumber + ', ' + aList[i].properties.city + ', ' + aList[i].properties.postcode; aOptions.push({ "value": optKey, "label": optLabel }); htmlVal += `${optKey} ${optLabel} <br />`; // add each value to htmlVal } $("#suggesstion-box").show(); $("#suggesstion-box").html(htmlVal); $("#search-box").css("background", "#FFF"); } }); });
