如何添加两个“on submit =”值的形式？ [英] How to add two "on submit=" values to a form?

问题描述

 < form onsubmit =return formCheck（this ）; return validate_dropdown（）; 
 action =somepage.php
 method =post
 name =something> 
  

当我在提交值上添加一个时，每个函数都可以单独工作，第一个函数的验证工作，而不是第二个。这里有什么不对？

解决方案

从onsubmit中移除返回并将它们添加到函数中：

onsubmit =return（formCheck（this）&& validate_dropdown（））

I am trying to validate my form using two separate JavaScript functions:

<form onsubmit="return formCheck(this); return validate_dropdown();"  
      action="somepage.php" 
      method="post" 
      name="something">

When I add just one on submit value, each function works fine individually, when I add two only the first function's validation works, not the second. What is wrong here?

解决方案

Remove the returns from the onsubmit and add them to the functions:

onsubmit="return (formCheck(this) && validate_dropdown())"
