jquery - insert values at certain index (or indices) javascript -

-

i have hit block in working on assignment. how insert value given index or indices?

for example, i'm working on hangman game. if word "harry", , player guesses letter "r" how turn array of underscores "_ _ r r _"?

what have below gets word separate js file, creates array of underscores (one each letter of returned word), , then, when user guesses letter, finds index or indices of occurrences of letter.

**i've updated code below. loop towards end goes array of underscores (wordtoguess[]) , splices in users input. need puts last guessed letter in front. example if word "bold" , last letter user guessed "l", wordtoguess array lbold. here know why is? i'm sure easy i'm overlooking, driving me nuts.

javascript

var word;  $(document).ready(function () {     setgameboard(); });  //when guess button clicked $('#btnguess').click(function () {     checkguess(); });  function getphrase() {     word = returnword();     alert(word); }  function setgameboard() {     getphrase();     wordtoguess = new array(word.length);       // place underscore each letter in answer word in divword div     (var = 0; < word.length; i++){        wordtoguess[i] = "_ ";      }     $('#divword').html(wordtoguess); }   function checkguess() {     var pos = 0;     var posarray = [];     var guessletter = $('#tbguessletter').val();      while ((pos = word.indexof(guessletter, pos)) > -1) {         posarray.push(++pos);     }      if (posarray.length == 0) {         alert(guessletter + " not in word.");     }      //splice in correct letters. not working 100%     for(i=0; < wordtoguess.length; i++){         wordtoguess.splice(posarray[i], 1, guessletter);         }         $('#divword').html(wordtoguess);      alert(posarray);      alert(guessletter); }

for modifying arrays in place, want array.prototype.splice()

https://developer.mozilla.org/en-us/docs/web/javascript/reference/global_objects/array/splice

from docs:

var myfish = ['angel', 'clown', 'mandarin', 'surgeon'];    // removes 0 elements index 2, , inserts 'drum'  var removed = myfish.splice(2, 0, 'drum');  // myfish ['angel', 'clown', 'drum', 'mandarin', 'surgeon']  // removed [], no elements removed    // removes 1 element index 3  removed = myfish.splice(3, 1);  // myfish ['angel', 'clown', 'drum', 'surgeon']  // removed ['mandarin']    // removes 1 element index 2, , inserts 'trumpet'  removed = myfish.splice(2, 1, 'trumpet');  // myfish ['angel', 'clown', 'trumpet', 'surgeon']  // removed ['drum']    // removes 2 elements index 0, , inserts 'parrot', 'anemone' , 'blue'  removed = myfish.splice(0, 2, 'parrot', 'anemone', 'blue');  // myfish ['parrot', 'anemone', 'blue', 'trumpet', 'surgeon']  // removed ['angel', 'clown']    // removes 2 elements index 3  removed = myfish.splice(3, number.max_value);  // myfish ['parrot', 'anemone', 'blue']  // removed ['trumpet', 'surgeon']

it looks behavior want in third example here replace 'drum' 'trumpet'.
