použít proměnnou pro vzdálenost v esri leaflet nearby??

Anonymous User

Ahoj:<\/P>

Jak mohu použít proměnnou při použití metody nearby na dotazové vrstvě, aby si uživatel mohl vybrat vzdálenost v rozbalovacím seznamu, nebo to není možné? <\/P>

 <\/P>

Zde je úryvek toho, co mám:<\/P>

HTML<\/P>

<select id="buffer" name="buffer">
<option value="60.96">200 stop<\/option>
<option value="152.4">500 stop<\/option>
<option value="213.36">700 stop<\/option>
<option value="304.8">1000 stop<\/option>
<\/select><\/P>

JAVASCRIPT<\/P>

var distance = document.getElementById("buffer").value;<\/P>

 <\/P>

function myFunction() {
if ((document.getElementById("pm1").checked == true) && (document.getElementById("tm1").checked == true)&& (document.getElementById("sr1").checked == true)){
pmquery.nearby(latlng, distance);

pmquery.run(function (error, featureCollection, response) {
if (error) {
console.log(error);
return;
}
L.geoJSON(featureCollection).addTo(map);
console.log('Nalezeno ' + featureCollection.features.length + ' prvků');
map.fitBounds(L.geoJSON(featureCollection).getBounds());
});

<\/P>

Yes that code looks like it should work. Make sure you check if your "distance" variable is actually defined within your function. You can use console.log to see if the value is defined. As a quick attempt, you could also move the line

var distance = document.getElementById("buffer").value;

 within your function "myFunction"
