验证思路
监听每个input控件的焦点离开(onblue),当焦点离开时调用验证函数,验证后修改第三栏文字,显示符合/不符合并返回true/false
实现代码:
index.html
<!DOCTYPE html> <html> <head> <title></title> <pnk rel="stylesheet" href="css.css" rel="external nofollow" > </head> <body> <form id="form" action="" method="post" onsubmit="return vipdate()"> <table class="table"> <tr> <td>雇员编号</td> <td> <input type="text" id="empnb" name="empnb" onblur="vapdateEmpnb()"> </td> <td> <span id="empnbMsg"></span> </td> </tr> <tr> <td>雇员姓名</td> <td> <input type="text" id="ename" name="ename" onblur="vapdateEname()"> </td> <td> <span id="enameMsg"></span> </td> </tr> <tr> <td>雇员职位</td> <td> <input type="text" name="epost" id="epost" onblur="vapdateEpost()"> </td> <td> <span id="epostMsg"></span> </td> </tr> <tr> <td>雇员日期</td> <td> <input type="text" name="" id="edate" name="edate" onblur="vapdateEdate()"> </td> <td> <span id="edateMsg"></span> </td> </tr> <tr> <td>基本工资</td> <td> <input type="text" name="esalary" id="esalary" onblur="vapdateEsalary()"> </td> <td> <span id="esalaryMsg"></span> </td> </tr> <tr> <td>佣金</td> <td> <input type="text" name="ebrok" id="ebrok" onblur="vapdateEbrok()"> </td> <td> <span id="ebrokMsg"></span> </td> </tr> <tr> <td colspan="3"> <input type="submit" autofocus="autofocus"> <input type="reset"> </td> </tr> </table> </form> </body> <script type="text/javascript" src="/UploadFiles/2021-04-02/FormVapdation.js">FormVapdation.js
