Question

尝试创建一个表单，强制用户选中带有短语“我接受条款和条件”的复选框，以便发送表单。

这就是我所拥有的，但它没有提交表格 - 我收到了错误。

我放在标题中的Javascript：

<script type="text/javascript">
   <!--

   function validate_form ( )
   {
   valid = true;

   if ( document.form1.cb.checked == false )
   {
   alert ( "Please check the Terms & Conditions box ." );
   valid = false;
   }

   return valid;
   }

   //-->
   </script>

形式：

    <form action="/cgi-bin/FormMail.pl" method="POST" name="frmOne"  id="frmOne">
    <input type=hidden name="recipient" value="XXX@XXX.com"/>
    <table width="100%" cellspacing="5" cellpadding="5" style="margin-top:-20px">

Answer 1

您正在引用表单和元素错误，请尝试以下操作：

<form name="frmOne" method="POST" onSubmit="return checkForm(frmOne);" action="/cgi-bin/FormMail.pl">

<script>
function checkForm(form) 
{
    if(!form.agree.checked) 
    { 
        alert("You must agree to this disclaimer before applying.");
        return false;
    }
}
</script>

我希望帮助

Answer 2

将<form action="/cgi-bin/FormMail.pl" method="POST" name="frmOne" id="frmOne">更改为<form action="/cgi-bin/FormMail.pl" method="POST" name="frmOne" id="frmOne" onSubmit="validate_form();">

你还有其他什么错误？

并将document.form1.cb.checked更改为document.frmOne.agree.checked

Answer 3

试试document.getElementById("disclaimer").checked == false。

必须复选框才能提交表单
