如何禁用按钮，如果没有输入包括空格字符的角度

<button id="myButton" onclick="myFunction()">点击我</button>

function myFunction() {
  document.getElementById("myButton").disabled = true;
}

<button id="myButton" onclick="myFunction()">点击我</button>

function myFunction() {
  document.getElementById("myButton").disabled = true;
}

function myFunction() {
  var inputValue = document.getElementById("myInput").value.trim(); // 获取输入值并去除前后空格

  if (inputValue === "") {
    document.getElementById("myButton").disabled = true;
  } else {
    document.getElementById("myButton").disabled = false;
  }
}
