Html 表格不会在IE 11中提交，其他所有表格都会成功提交

我是一个编程新手，这是我的第一个问题。 我有一个引导模式，可以打开一个联系我们表单。在Firefox中，表单按预期提交回发。在IE 11中，单击发送按钮只是挂起，没有任何内容。关闭窗口按钮与文本输入字段所需的属性一样工作。 我见过其他类似的问题，但我没有在任何字段或按钮上遗漏名称属性。我也没有复制标记中的type=submit属性。我已经尝试过使用button type=submit和其他我能想到的方法。除提交内容外，模态和形式元素均有效。按钮的行为就像被单击一样，但没有任何更改，也没有提交任何内容。任何帮助都太好了

相关代码：

<form class="form-horizontal" method="post" name="PortalContactUsForm" id="PortalContactUsForm">
<input type="submit" form="PortalContactUsForm" name="SendEmailButton" id="SendEmailButton" class="btn btn-primary" value="Send">

完整的模态和形式代码：

<div id="myPortalModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myPortalModalLabel" aria-hidden="true">
        <div class="modal-header">
            <button type="button" name="ModalCloseButton" class="close" data-dismiss="modal" aria-hidden="true">x</button>

        </div>
        <div class="modal-body">

这段代码是否存在于您可以链接的网站上？当您尝试单击“提交”时，是否可以在InterExplorer中拍照并发布控制台所说的内容？控制台未显示任何内容。0个错误、0个警告、0条消息。这是个难题。我认为模态是个问题，因为模态函数的形式和预期的一样。不知道为什么IE如此讨厌引导模式……我最终禁用了submit按钮的submit功能，并使用onclick属性启动了一个javascript方法来验证表单并提交它。尽管如此，我还是想知道如何用我原来的方式来做。为什么你要这样填写这些值？这是一个PHP页面吗？
