:disabled - CSS: Cascading Style Sheets 编辑

The :disabled CSS pseudo-class represents any disabled element. An element is disabled if it can't be activated (selected, clicked on, typed into, etc.) or accept focus. The element also has an enabled state, in which it can be activated or accept focus.

/* Selects any disabled <input> */
input:disabled {

Examples

This example shows a basic shipping form. It uses the JavaScript change event to let the user enable/disable the billing fields.

HTML

<form action="#">
  <fieldset id="shipping">
    <legend>Shipping address</legend>
    <input type="text" placeholder="Name">
    <input type="text" placeholder="Address">
    <input type="text" placeholder="Zip Code">
  </fieldset>
  <br>
  <fieldset id="billing">
    <legend>Billing address</legend>
    <label for="billing-checkbox">Same as shipping address:</label>
    <input type="checkbox" id="billing-checkbox" checked>
    <br>
    <input type="text" placeholder="Name" disabled>
    <input type="text" placeholder="Address" disabled>
    <input type="text" placeholder="Zip Code" disabled>
  </fieldset>
</form>

CSS

input[type="text"]:disabled {
  background: #ccc;
}

JavaScript

// Wait for the page to finish loading
document.addEventListener('DOMContentLoaded', function () {
  // Attach `change` event listener to checkbox
  document.getElementById('billing-checkbox').onchange = toggleBilling;
}, false);

function toggleBilling() {
  // Select the billing text fields
  var billingItems = document.querySelectorAll('#billing input[type="text"]');

  // Toggle the billing text fields
  for (var i = 0; i < billingItems.length; i++) {
    billingItems[i].disabled = !billingItems[i].disabled;
  }
}
