[Solved] How to change all my value with onclick?

by


You have a function, but you’re not calling it. Try changing the onclick() to change() and selecting the element using this, (as a parameter).

function change(elem) {
  if (elem.value == "E") elem.value += "\u266D";
  else elem.value = "E";
}
