Add row at specific point in div

Question

I am making a small hang man style game in HTML and I am trying to click on a letter that the user correctly guessed wherever he was in div. Here is what I still have:

var words = ['dog', 'mouse', 'horse', 'fossil', 'christmas', 'mountain', 'javascript', 'glitter', 'pringles', 'connect'];
var output = "";
var gRand = "";
var gWordAry = "";
function startGame() {
    var rand = words[Math.floor(Math.random() * words.length)]; //gets a random word from the array, stores as rand
    var wordAry = rand.split(''); //splits random word into its own array and each letter is in the array
    gRand = rand; //stores random word as global var
    gWordAry = wordAry;
    alert(wordAry);
    $('#hangmanGame').show();
    $('#startBtn').hide();
    //alert(rand);
    for (i = 0; i < wordAry.length; i++) { //draws a dash for every letter in the random word array after split
        //draw canvas dash
        output += ' _ ';
        $('#wordGuess').html(output);
    }


    //alert(output);


}

function guess(letter) {
    var letterID = letter.toLowerCase(); //converts letter to lowercase from html
    //alert(letterID);
    var foundLetter = 0;
    for (i=0;i<gWordAry.length; i++){
        if (gWordAry[i] == letterID){ //if a letter in the word array = the letter clicked this will run
            //alert('correct');
            foundLetter++;
            displayLetter(letterID);
        }
    }
    if (foundLetter == 0){ //if no letters in the array are found this will run
        alert('Try Again');
    }

}

function displayLetter(letterID){
    //displays all letters in the word
    $('#wordGuess').append(letterID)
}

HTML:

<div id="hangmanGame">
    <div id="wordGuess">  </div>  //THIS IS THE DIV WHERE THE LETTERS ARE GOING
    <table style="margin: auto;position: relative;top: 500px;">
        <tr>

    </table>
</div>

The code may be a little dirty. I am new to coding. Can anyone help? What I have adds a letter to the end _.

Answer 1

Here is the working version of the game :)

replaceAt function taken from here

var words = ['dog'];
var output = "";
var gRand = "";
var gWordAry = "";

function startGame() {
  var rand = words[Math.floor(Math.random() * words.length)]; //gets a random word from the array, stores as rand
  var wordAry = rand.split(''); //splits random word into its own array and each letter is in the array
  gRand = rand; //stores random word as global var
  gWordAry = wordAry;
  alert(wordAry);
  $('#hangmanGame').show();
  $('#startBtn').hide();
  //alert(rand);
  for (i = 0; i < wordAry.length; i++) { //draws a dash for every letter in the random word array after split
    //draw canvas dash
    output += ' _ ';
    $('#wordGuess').html(output);
  }


  //alert(output);


}
currentIndex = 0
function guess(letter) {
  var letterID = letter.toLowerCase(); //converts letter to lowercase from html
  //alert(letterID);
  var foundLetter = 0;
  for (i = 0; i < gWordAry.length; i++) {
    if (gWordAry[i] == letterID && gWordAry[i] !== '_') { //if a letter in the word array = the letter clicked this will run
      //alert('correct');
      if (currentIndex == i){
      foundLetter++;
      gWordAry[i] = '_'
      displayLetter(letterID, currentIndex++);
        
      break;
        }
    }
  }
  if (foundLetter == 0) { //if no letters in the array are found this will run
    alert('Try Again');
  }

}
String.prototype.replaceAt = function(index, character) {
  return this.substr(0, index) + character + this.substr(index + character.length);
}

function displayLetter(letterID,i) {
  //displays all letters in the word
  var toReplace = $('#wordGuess').html();


 $('#wordGuess').html($('#wordGuess').html().replaceAt($('#wordGuess').html().indexOf('_'), letterID))
}
startGame()
