  193.         });
  194.     });
  195. </script>
  196. </body>
  197. </html>

下面看看测试效果：

当不输入内容直接提交时，提示不能为空：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70

当输入字符不符合规定位数时，提示：

watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTU5NTcwMA_size_16_color_FFFFFF_t_70 1

可根据需求继续添加表单验证
