表单进度条

Question

我希望设置一个具有进度条的表单，同时用户填写输入字段。我已经设置了我从教程和在线知道的所有内容，但它不起作用。

请查看是否有人能弄清楚它为什么不起作用。

这是示例 JS 代码

      $("#form input").keyup(function() {
      var numValid = 0;
      $("#form input[required]").each(function() {
          if (this.validity.valid) {
              numValid++;
          }
      });

      var progress = $("#progress"),
          progressMessage = $("#message");

      if (numValid == 0) {
          progress.attr("value", "0");
          progressMessage.text("Please Enter Student ID.");
      }
      if (numValid == 1) {
          progress.attr("value", "10");
          progressMessage.text("Please Enter the First Name.");
      }
      if (numValid == 2) {
          progress.attr("value", "20");
          progressMessage.text("Please Enter the Last Name.");
      }
      if (numValid == 3) {
          progress.attr("value", "30");
          progressMessage.text("Please Enter Your E-mail");
      }
      if (numValid == 4) {
          progress.attr("value", "40");
          progressMessage.text("Please Enter a Password.");
      }
      if (numValid == 5) {
          progress.attr("value", "50");
          progressMessage.text("Please Re-Enter a Password.");
      }
      if (numValid == 6) {
          progress.attr("value", "60");
          progressMessage.text("Please Enter A Street Address.");
      }
      if (numValid == 7) {
          progress.attr("value", "70");
          progressMessage.text("Please Enter a City.");
      }
      if (numValid == 8) {
          progress.attr("value", "80");
          progressMessage.text("Please Enter a ZipCode.");
      }
      if (numValid == 9) {
          progress.attr("value", "100");
          progressMessage.text("Please Pick a State and Submit the Form.");
      }

      });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script‌​>
<script>
$(function(){ // do not forget to add this too
$("#form input").keyup(function() {
          var numValid = 0;
          $("#form input[required]").each(function() {
              if (this.validity.valid) {
                  numValid++;
              }
          });
.

.
.
.
.
});
}); // and the closing braces
</script>

PS：注意两个不同的<script> 标签。他们需要分开。另外不要忘记将您的 keyup 函数包装在 $(function(){}); 中
