    <body>

    <form  action="ui" name="myform" onsubmit="return validateForm()" method="get">
    <h2><p align="center"><b>User Management System</b></p></h2><br>
    <b>
    User ID : 
    <input type="text" name="id" required>  

    User Age : 
    <input type="text" name="age" required>  

    User Name :  
    <input type="text" name="name" required>  

    User Place :  
    <input type="text" name="place" required>   

    Enter your choice: 
    <input type="text" name="choice" required> 

    <input type="submit" value="Submit">
    </b>
    </form><b>

我想使用Java脚本验证用户的输入，并且还希望将输入提交到此表单中名为“ui”的servlet名称。但验证没有发生。任何人都可以指导我从单一表格中执行这两项操作吗？

Answer 1

有一点拼写错误。

<form  action="ui" name="myform" onsubmit="return validateForm()" method="get">

在上面的换行myform to myForm中，它会起作用。

如何使用多个表单操作，如输入验证和输入提交到servlet fron单一形式？
