将数组拆分为唯一字符或检查字符是否存在

Question

I've created 3 buttons with different names, when button A is clicked it appends the value to an array. for an example

<a href="#" class="answer" data-value="Football">Football</a>

clicking that will add "Football" to a blank array I'm creating a basic hangman game and want to know how I would go about either clicking a letter and checking if that letter exists within the array (ie clicking f and then checking whether f exists in the word football), or splitting the array into individual characters (so football becomes f, o, o, t, b, a, l, l) and then clicking a letter will check if that letter exists within the array.

Hopefully that made sense as im quite new to this, so any help would be appreicated

Answer 1

You can use split to create an array of characters, eg

var guessWord = "Football";
var checkArray = guessWord.split("");

check to see if characters is in array:

checkArray.indexOf("o")!=-1
