如何从模式形式的bootstrap中发布数据？

I have a page using a modal to get the users email and I want to add it to a list of subscribers(which is a django model). Here is the modal code for that:

我有一个页面使用模态来获取用户的电子邮件，我想将它添加到订阅者列表（这是一个django模型）。这是模态代码：

<div id="notifications" class="modal hide fade" role="dialog" ara-labelledby="Notification" aria-hidden="true">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">X</button>
        <h4>Subscribe to Status Notifications</h4>
    </div>
    <form>
        <div class="modal-body">
            <input type="email" placeholder="email"/>
            <p>This service will notify you by email should any issue arise that affects your plivo service.</p>
        </div>
        <div class="modal-footer">
            <input type="submit" value="SUBMIT" class="btn"/>
        </div>
    </form>
</div>

I tried to look in the Twitter Bootstrap doc but it really is minimal. I want to POST the data to a django view thats listening for POST requests.

我试图查看Twitter Bootstrap文档，但它确实很小。我想将数据发布到侦听POST请求的django视图。

This is the bare essential. I am using regex to compare the format of the email before storing the email id. So if the email does not match the regex the view returns an Invalid Email. So I would like to notify the user about that within the modal itself. But I really have no idea as to how to do this. Someone please help.

这是必不可少的。我正在使用正则表达式来比较电子邮件的格式，然后再存储电子邮件ID。因此，如果电子邮件与正则表达式不匹配，则视图将返回无效的电子邮件。所以我想在模态本身内通知用户。但我真的不知道如何做到这一点。有人请帮忙。

更新：

Tried this based on karthikr's answer:

根据karthikr的回答尝试了这个：

<form id="subscribe-email-form" action="/notifications/subscribe/" method="post">
    <div class="modal-body">
    <input type="email" placeholder="email"/>
        <p>This service will notify you by email should any issue arise that affects your service.</p>
    </div>
    <div class="modal-footer">
    <input id="subscribe-email-submit" type="submit" value="SUBMIT" class="btn" />
    </div>
</form>

<script>
    $(function(){
       $('subscribe-email-form').on('submit', function(e){
            e.preventDefault();
            $.ajax({
                url: "/notifications/subscribe/",
                type: "POST",
                data: $("subscribe-email-form").serialize(),
                success: function(data){
                    alert("Successfully submitted.")
                }
            });
       }); 
    });
</script>

There is something that is confusing me. What about the onclick event of the modal button?

有些事让我感到困惑。模态按钮的onclick事件怎么样？

I got it! I added name="Email" in the line <input type="email" placeholder="email"/>

我知道了！我在行中添加了name =“Email”

The django field is looking for the Email Field. So in my django view the code is :

django领域正在寻找电子邮件领域。所以在我的django视图中代码是：

request.POST.get("Email", '') so specifying the field name helps.

request.POST.get（“Email”，“”）因此指定字段名称会有所帮助。

But it takes me to the url where I am posting. I want it to display a alert in the same page.

但它需要我到我发布的网址。我希望它在同一页面中显示警报。

UPDATE 2:

更新2：

So part 1 is working. As in the posts are working. Now I need to show a modal for the success or failure. Heres what I am trying:

所以第1部分正在运作。如在帖子正在工作。现在我需要显示成功或失败的模态。继承人我在尝试：

So I created this modal with a textarea:

所以我用textarea创建了这个模态：

<div id="subscription-confirm" class="modal hide fade in" aria-hidden="true">
    <div class="modal-header">
        <label id="responsestatus"></label>
    </div>
</div>

And the javascript:

和JavaScript：

<script>
    $(function(){
        $('#subscribe-email-form').on('submit', function(e){
            e.preventDefault();
            $.ajax({
                url: 'notifications/subscribe/',
                type: 'POST',
                data: $('#subscribe-email-form').serialize(),
                success: function(data){
                     $('#responsestatus').val(data);
                     $('#subscription-confirm').modal('show');    
                }
            });
        });
    });
</script>

So the modal comes up. but the data is not set into the label field of the modal.

所以模态出现了。但数据未设置到模态的标签字段中。

2 个解决方案

#1

You need to handle it via ajax submit.

你需要通过ajax提交来处理它。

Something like this:

像这样的东西：

$(function(){
    $('#subscribe-email-form').on('submit', function(e){
        e.preventDefault();
        $.ajax({
            url: url, //this is the submit URL
            type: 'GET', //or POST
            data: $('#subscribe-email-form').serialize(),
            success: function(data){
                 alert('successfully submitted')
            }
        });
    });
});

A better way would be to use a django form, and then render the following snippet:

更好的方法是使用django表单，然后呈现以下代码段：

<form>
    <div class="modal-body">
        <input type="email" placeholder="email"/>
        <p>This service will notify you by email should any issue arise that affects your plivo service.</p>
    </div>
    <div class="modal-footer">
        <input type="submit" value="SUBMIT" class="btn"/>
    </div>
</form>

via the context - example : {{form}}.

通过上下文 - 例如：{{form}}。

I was facing same issue not able to post form without ajax. but found solution , hope it can help and someones time.

我面临同样的问题，没有ajax就无法发布表格。但找到了解决方案，希望它可以帮助和某些人的时间。

<form name="paymentitrform" id="paymentitrform" class="payment"
                    method="post"
                    action="abc.php">
          <input name="email" value="" placeholder="email" />
          <input type="hidden" name="planamount" id="planamount" value="0">
                                <input type="submit" onclick="form_submit() " value="Continue Payment" class="action"
                                    name="planform">

                </form>

You can submit post form, from bootstrap modal using below javascript/jquery code : call the below function onclick of input submit button

您可以使用以下javascript / jquery代码从bootstrap模式提交帖子表单：调用以下函数onclick输入提交按钮

    function form_submit() {
        document.getElementById("paymentitrform").submit();
   }
