如何在 javascript

中获取占位符的值

我不想JQuery获取值

谁能告诉我如何获得它

Answer 1

const ip = document.getElementById("ip").getAttribute('placeholder');

console.log(ip);

<input type="text" placeholder="some value" id="ip">

您可以使用 getAttribute() 方法获取 DOM 元素的属性值。 MDN - Element.getAttribute()

Answer 2

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
function myFunction() {
  var x = document.getElementById("myText").placeholder;
  console.log(x);
}
</script>

<html>
<body>

First Name: <input type="text" id="myText" placeholder="Name">

<p>Click the button to view the placeholder content in console.log</p>

<button onclick="myFunction()">Click Here</button>

</body>
