                  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.
