Question

好吧它确实可以在PHP中运行，但是如果我修改文件以便我的index.php看起来像这样

<?php

include('header');
include('main_content');
include('footer');

?>

然后它不起作用。

这是我渲染的hmtl（firefox）

      <div class="form-row"><input class="submit" type="submit" value="Submit"></div>
    </form>

<!-- this is the jQuery validation ----------->

</div></div></body>

</html><script type="text/javascript">
    $(document).ready(function() {
      $("#form1").validate({
        rules: {
          name: "required",// simple rule, converted to {required:true}
          email: {// compound rule
          required: true,
          email: true
        },
        url: {
          url: true
        },
        comment: {
          required: true
        }
        },
        messages: {
          comment: "Please enter a comment."
        },
        errorPlacement: function (error, element) {
                    element.css('background', '#ffdddd');
                }
      });
    $("#form2").validate({
    rules:{
        name2:"required",
        pass: "required"
    }
})
    });
  </script>

可能有什么不对？我知道如果查询验证不是第一个包含，则查询验证不起作用。但它是标题中的第一个包含。渲染的HTML看起来很好。该文件位于js文件夹中。

我已花了几个小时的时间。

此代码有效

这是另一个可行的html页面的代码。如果验证失败，jQuery将不会提交表单。

Answer 1

您已将jquery包括两次，删除最后一个。

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>  
<script type="text/javascript" src="js/jquery.validate.js"></script> 
<!--  <script src="js/jquery.min.js" ></script>  --/>

此外，除了名称之外，您可能还希望在表单字段中使用“id”属性。名称传递给服务器，而id通常与javascript一起使用。

将最后一个脚本移到body标签或head标签内。

Answer 2

一个疯狂的猜测，但尝试在结束<script>标记之前移动</body>块。目前尚不清楚哪个include'd文件包含哪些内容，但在结束</body>标记后不应该出现任何内容。

jquery验证在php中不起作用
