我有一个包含2个字段的表单(对于此示例),我使用JavaScript验证,如果字段包含数据,则表单将在用户单击“提交”按钮时提交。我在表单标签中使用iframe将输出发送到同一页面。
我想要做的是在表单下方显示一条消息,说明"感谢您的提交和#34;。我很难想出这个部分。
function SubmitRentalForm()
{
var bValid = true;
var sFirst = document.getElementById("fname").value;
var sLast = document.getElementById("lname").value;
if ( (sFirst.trim() == "") || (sLast.trim() == "") )
{
bValid = false;
return bValid;
}
return bValid;
}

<div class="main">
<form name="RentalForm" action="email-rental.php" method="POST" onsubmit="return SubmitRentalForm()" target="myFrame">
<table id="form_corners_rental" border="0" cellspacing="5">
<tr>
<td>First Name</td>
<td><input type="text" id="fname" name="fname" size="50" maxlength="60" placeholder="Enter First Name" onblur="ValidateField(name)" />
<span id="errorname" style="font-size:9px;color:darkred;"></span>
</td>
<td>Last Name</td>
<td><input type="text" id="lname" name="lname" size="50" maxlength="60" placeholder="Enter Last Name" onblur="ValidateField(name)" /></td>
</tr></table>
<div id="Msg" style="display:none">
Thank you for your form submission.
</div>
<br/><br/>
<input id="submit-btn-rental" type="submit" value="Rent Now">
</form>
</div>
<iframe name="myFrame" width="1" height="1" style="border:none"></iframe>
&#13;
我添加了div标签,但我不知道该怎么做。
有人可以指出我正确的方向。

只需在提交表单时更改msg div的样式
function SubmitRentalForm()
{
var msg =document.getElementById("Msg")
var bValid = true;
var sFirst = document.getElementById("fname").value;
var sLast = document.getElementById("lname").value;
if ( (sFirst.trim() == "") || (sLast.trim() == "") )
{
bValid = false;
return bValid;
}
msg.style.display="inline-block"
return bValid;
}
&#13;
<div class="main">
<form name="RentalForm" action="email-rental.php" method="POST" onsubmit="return SubmitRentalForm()" target="myFrame">
<table id="form_corners_rental" border="0" cellspacing="5">
<tr>
<td>First Name</td>
<td><input type="text" id="fname" name="fname" size="50" maxlength="60" placeholder="Enter First Name" />
<span id="errorname" style="font-size:9px;color:darkred;"></span>
</td>
<td>Last Name</td>
<td><input type="text" id="lname" name="lname" size="50" maxlength="60" placeholder="Enter Last Name" /></td>
</tr></table>
<div id="Msg" style="display:none">
Thank you for your form submission.
</div>
<br/><br/>
<input id="submit-btn-rental" type="submit" value="Rent Now">
</form>
</div>
<iframe name="myFrame" width="1" height="1" style="border:none"></iframe>

试试这个
GROUP BY
$query->whereHas('customers', function($query) {
$query->where(...)
})
