Javascript indexOf() always returns -1
- by Thomas
I try to retrieve the index of en element in an array.
This works perfectly
var onCreate = function (event) {
console.assert(markers[markerId] === undefined);
var markerId = event.markerId;
markers[markerId] = {};
var marker = markers[markerId];
// create the container object
marker.object3d = new THREE.Object3D();
marker.object3d.matrixAutoUpdate = false;
scene.add(marker.object3d);
//UPDATE ARRAY HOLDING CURRENT MARKERS
console.log("ON CREATE");
console.log("current detected markers: " + currentMarkers);
var idx = currentMarkers.indexOf(markerId); // Find the index
console.log("marker " + event.markerId + " has index: " + idx);
if(idx==-1) // if does not exist
currentMarkers.push(markerId);
But this doesnt...
var onDelete = function (event) {
console.assert(markers[event.markerId] !== undefined);
var markerId = event.markerId;
//UPDATE ARRAY HOLDING CURRENT MARKERS
console.log("ON DELETE");
console.log("current detected markers: " + currentMarkers);
var idxx = currentMarkers.indexOf(markerId); // Find the index
console.log("marker " + markerId + " has index: " + idxx);
if(idxx != -1) {// if DOES exist
currentMarkers.splice(idxx, 1); //Delete
var idxxx = currentMarkersCoverChecked.indexOf(markerId); // Find the index
if(idxxx == -1) // if does NOT exist, so if not being checked
checkMarkerCovered(markerId);
}
onDeleteRandom(markerId);
var marker = markers[markerId];
scene.remove(marker.object3d);
delete markers[markerId];
Look at my console output:
ON CREATE
current detected markers: 2,1,4
marker 3 has index: -1
ON CREATE main.js:266
current detected markers: 2,1,4,3
marker 4 has index: 2
ON DELETE
current detected markers: 2,1,4,3
marker 2 has index: -1
ON CREATE
current detected markers: 2,1,4,3
marker 2 has index: 0
ON DELETE
current detected markers: 2,1,4,3
marker 1 has index: -1
