javascript - How can I select a specific ID to do something?

I'm currently working on a project, now I'm facing a problem where I want to select specific IDs to do something.

How can I select specific IDs to get an img so a wall can be created?

As you can see, every tile has it's own unique tile id, now I want to select all the ids from tile0-0 to tile 0-12 and create an img for those unique ids.

How can I do that?


The code that creates those tiles:

function DrawMap()
{
  var X = Map.length;
  var Y = Map[0].length;

  var Output = "";
  for(var x = 0; x < X; x++)
  {
    for(var y = 0; y < Y; y++)
    {
      var _x = ((x*32)+(y*-32)+OffsetX);
      var _y = ((x*16)+(y*16)+OffsetY);

      if(Map[x][y])
        Output += '<img id="tile'+x+'-'+y+'" class="square" style="top: ' + _y + 'px; left: ' + _x + 'px;" src="/web/img/rooms/on.png" alt="Click To Remove" />';
      else
        Output += '<img id="tile'+x+'-'+y+'" class="square" style="top: ' + _y + 'px; left: ' + _x + 'px;" src="/web/img/rooms/off.png" alt="Click To Add" />';
    }

You can select all elements with this code:

document.querySelectorAll('[id^="tile0-"]');
