Change of variable value

There's a variable.
document.turn = "Text 1"♪ I need her to matter ♪Text 1Changed consecutivelyText 2♪ I mean, first use.document.turn♪Text 12nd -Text 2♪ I hope you can help me, thank you very much in advance.<head> <script> function onClick(sender) { document.turn = "X" if (sender.innerText == ""){ sender.innerHTML = document.turn } } </script> </head> <body> <table frame="void" align="center"> <tbody> <tr> <td id="c1" class="Square" onclick="onClick(this);"></td> <td id="c2" class="Square" onclick="onClick(this);"></td> <td id="c3" class="Square" onclick="onClick(this);"></td> </tr> <tr> <td id="c4" class="Square" onclick="onClick(this);"></td> <td id="c5" class="Square" onclick="onClick(this);"></td> <td id="c6" class="Square" onclick="onClick(this);"></td> </tr> <tr> <td id="c7" class="Square" onclick="onClick(this);"></td> <td id="c8" class="Square" onclick="onClick(this);"></td> <td id="c9" class="Square" onclick="onClick(this);"></td> </tr> </tbody> </table> </body>

In this case, the branches are sufficient
elsewhere there will be a change betweenxandofunction onClick(sender) { var steps = {"X":"O", "O":"X"}; //порядок смен, после X->O, после O->X if (sender.innerText == ""){ sender.innerHTML = "X";//если первый раз - устанавливаем X }else{ sender.innerHTML = steps[sender.innerText]; } }UPDATE: for comment
var steps = {"X":"O", "O":"X"}; //порядок смен, после X->O, после O->X var current = "X";function onClick(sender) {
if (sender.innerText == ""){// если пустая ячейка
sender.innerHTML = current; //устанавливаем текущее значение
current = steps[current];//меняем на следующее
}
}
