php - 仅验证我的文本框中的数字和字母

Question

愉快的一天大家..我在我的 php 文件中有这个 java 脚本代码，我用它作为我的验证器..用于我文本框中不同字段的输入...我唯一的问题是我不知道如何创建一个只接受字母的验证......在我的名字和姓氏字段中......期待任何帮助谢谢祝你有美好的一天......我也想知道如何只在我的领域接受数字 super 感谢^ ^,

代码如下:

<script type='text/javascript'>

$(document).ready(function()
  {
       $('#employee_form').validate({
         submitHandler:function(form)
       {
          $(form).ajaxSubmit({
          success:function(response)
          {
             tb_remove();
             post_person_form_submit(response);
           },
        dataType:'json'
       });

   },

    errorLabelContainer: "#error_message_box",
    wrapper: "li",
    rules: 
    {
        first_name: "required",
        last_name: "required",

        username:
        {
            required:true,
            minlength: 5
        },

        password:
        {
            <?php
            if($person_info->person_id == "")
            {
            ?>
            required:true,
            <?php
            }
            ?>
            minlength: 8
        },  
        repeat_password:
        {
            equalTo: "#password"
        },
        email:
        {               
            required:true,
            email: "email"
        }
    },
    messages: 
    {
        first_name: "<?php echo $this->lang->line('common_first_name_required'); ?>",
        last_name: "<?php echo $this->lang->line('common_last_name_required'); ?>",
        username:
        {
            required: "<?php echo $this->lang->line('employees_username_required'); ?>",
            minlength: "<?php echo $this->lang->line('employees_username_minlength'); ?>"
        },

        password:
        {
            <?php
            if($person_info->person_id == "")
            {
            ?>
            required:"<?php echo $this->lang->line('employees_password_required'); ?>",
            <?php
            }
            ?>
            minlength: "<?php echo $this->lang->line('employees_password_minlength'); ?>"
        },
        repeat_password:
        {
            equalTo: "<?php echo $this->lang->line('employees_password_must_match'); ?>"
        },

        email:
        {
            required: "<?php echo $this->lang->line('common_email_name_required'); ?>",
            email: "<?php echo $this->lang->line('common_email_invalid_format'); ?>"
        }

    }
   });
});
 </script>
