我有一个表格，可让您输入数据并附加文件并通过电子邮件发送。它适用于我的手机、safari、firefox 和 chrome，但我无法让它在 IE 中运行。（它甚至不会发布到 php 页面。）
HTML：
<form method="post" id="mainForm" enctype="multipart/form-data" action="email.php">
<span class="hide" id="status"></span>
<div class="rowElem">
<label for="name">Member Name:</label>
<div class="formRight">
<input id="name" type="text" name="name" required placeholder="John Doe" />
</div>
</div>
<div class="rowElem">
<label for="email">Member Email: </label>
<div class="formRight">
<input id="email" type="email" name="email" required placeholder="john.doe@email.com" />
</div>
</div>
<div class="rowElem">
<label for="subject">Subject: </label>
<div class="formRight">
<input id="subject" type="text" name="subject" required placeholder="Phone Call Follow Up"/>
</div>
</div>
<div class="rowElem">
<label for="message">Message: </label>
<div class="formRight">
<textarea id="message" name="message" required ></textarea>
</div>
</div>
<div class="rowElem">
<label for="attachment">Attachment: </label>
<div class="formRight">
<input id="attachment" type="file" name="attachment"/>
</div>
</div>
<div class="rowElem">
<button class="submit">Send Email</button>
<button class="reset" onClick="resetForm()">Reset Form</button>
</div>
</form>
