为自己节省 90k 额外脚本:

Save yourself 90k of extra script:

<script type="text/javascript">

  function doSubmit(form) {
    var urls = form['url'];
    var i = urls && urls.length;
    while (i--) {
      if (urls[i].checked) {
        window.location = urls[i].value;
      }
    }
    return false;
  }

  </script>

  <form action="" onsubmit="return doSubmit(this)">
    <input type="radio" name="url" value="http://www.google.com"> Google
    <input type="radio" name="url" value="http://www.yahoo.com"> Yahoo
    <input type="submit" value="Submit">
  </form>

哦，永远不要给表单控件命名为submit"，因为它会掩盖表单的提交方法.如果必须，请将其命名为submitButton"或类似名称.

Oh, and never give a form control a name of "submit" as it will mask the form's submit method. If you must, name it "submitButton" or similar.
