javascript - 使用javascript创建基本按钮

Question

我正在制作一个按钮，每次点击都会从“你”>“哇”>“旅行”变化。

但它会报错“Uncaught TypeError: onoff is not a function at HTMLInputElement.onclick (7.html:15)”

你能帮我解决这个问题吗？

function onoff() {
  currentvalue = document.getElementById('onoff').value;
  
  if (currentvalue == "you") {
    document.getElementById('onoff').value = "wow";
  } else if (currentvalue == "wow";) {
    document.getElementById('onoff').value = "travel";
  } else {
    document.getElementById('onoff').value = "you";
  }
}

<input type="button" value="you" id="onoff" onclick="onoff();">

Answer 1

function onoff() {
  var currentvalue = document.getElementById('onoff').value;
  if (currentvalue == "you") {
    document.getElementById('onoff').value = "wow";
  } else if (currentvalue == "wow") {
    document.getElementById('onoff').value = "travel";
  } else {
    document.getElementById('onoff').value = "you";
  }
}

<input type="button" value="you" id="onoff" onclick="onoff()">

完成，一切正常:

我已经替换了 onclick="onoff();" 和 else if (currentvalue == "wow";)

问题只是语法错误
