iPhone上的模态框没有滚动

Question

你好想知道我是否可以得到一些帮助，因为我在网上没有找到任何可以解决这个问题的东西，在 iphone 上，当页面很大时，twitter 引导模式框没有滚动来获取框的页脚。

使用的代码

    <div class="modal hide" id="electricityModal">

        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
            <h3>Submit A Electricity Reading</h3>
        </div>

        <div class="modal-body">

            <div class="control-group">
                <label class="control-label">Date/Time</label>
                    <div class="controls">
                        <span class="input-medium uneditable-input">22 Aug 2012, 9:45AM</span>
                    </div>
            </div>

            <div class="control-group">
                <label class="control-label" for="reading-peak">Peak</label>
                <div class="controls">
                    <input style="letter-spacing: 10px;" type="text" id="reading-peak" class="input-medium">
                </div>
            </div>

            <div class="control-group">
                <label class="control-label" for="reading-off-peak">Off Peak</label>
                <div class="controls">
                    <input style="letter-spacing: 10px;" type="text" id="reading-off-peak" class="input-medium">
                </div>
            </div>

        </div>

        <div class="modal-footer">
            <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
            <button class="btn btn-primary">Lodge Reading</button>
        </div>
    </div>

Answer 1

我相信为父 div (id:electricityModal) 提供 max-height css 属性可能会有所帮助并提供滚动条。选择最适合您的高度。说像 250 像素这样的东西。

Answer 2

解决此问题的方法是添加以下 css（在 bootstraps github 问题上找到）

    @media (max-width: 480px) {

        .modal {
            height: 500px; /* Set a default max height of the modal (adjusted later)*/
            position: fixed; /* Display modal in the centre of your screen */
            overflow-y: scroll; /*  Ensure that the modal is scroll-able */
            -webkit-overflow-scrolling: touch; /* Avoid having to use 2 finger scroll on iOS    */
        }
        .modal.fade.in{
            top: 5px; /* Use more screen real estate */
        }
        .modal-body{
            /* Increase the max height of the modal body to try & avoid both it,
             * and the modal container having scroll bars which results in odd behavior */ 
            max-height: 2400px; 
        }   
    }

    /* Now adjust the height so it handles various screen sizes & orientations */
    /* You could make this as granular as you like, or have it more granular at common screen sizes
     * but it should start at the height we set on .modal (i.e. 500px) & work down */
    @media (max-width: 480px) and (max-height: 500px){.modal{ height: 450px}}
    @media (max-width: 480px) and (max-height: 450px){.modal{ height: 400px}}
    @media (max-width: 480px) and (max-height: 400px){.modal{ height: 350px}}
    @media (max-width: 480px) and (max-height: 350px){.modal{ height: 300px}}
    @media (max-width: 480px) and (max-height: 300px){.modal{ height: 250px}}
    @media (max-width: 480px) and (max-height: 250px){.modal{ height: 200px}}
    @media (max-width: 480px) and (max-height: 200px){.modal{ height: 150px}}
