Question

使用bootstrap v4.0.0-alpha是非常棒的，这就是我要找的：我需要将模式框放在容器div中，而不是整个屏幕上。

我尝试更改一些内置的CSS类，是的，有些JavaScript :)，如：

z-index：1051;

更改右侧navBar但不满足于那个，任何简单的解决方案？

Answer 1

创建变量var mod并在其中加载模态;
```
var mod = $('.modal');
```
在容器内创建div <div class="insidemodal"></div>，以显示模态

使用Bootstrap 4 modal event listener，首选show.bs.modal并将var mod = $('.modal');放入其中，并在模拟即将显示时在insidemodal选择器中加载模式。

$('#myModal').on('show.bs.modal', function () {
    var mod = $('.modal'); //Create variable and load modal in it
    $('.insidemodal').html(mod); //Load modal to `insidemodal` Selector
});

在Modal CSS

中进行以下更改

.modal-backdrop {
    display:none //<---Kill the modal backdrop
}
.modal-backdrop.in {
    opacity: 0;
}
.modal {
    z-index: inherit !important; //<--overwrite modal default z-index: 1050
    position: relative; //<change position from absoulte
}

所以最终守则将是

JS

$(document).ready(function () {
    $('#myModal').on('show.bs.modal', function () {
        var mod = $('.modal'); 
        $('.insidemodal').html(mod);
    });
});

CSS

.title {
    background: green;
    color:#fff;
    padding: 5px;
    text-align:center;
    border:1px solid;
}
.menu {
    background: blue;
    color:#fff;
    padding: 5px;
    text-align:center;
    border:1px solid;
}
.insidemodal {
    background: red;
    border:1px solid;
    padding: 5px;
}
.modal-backdrop {
    display:none
}
.modal-backdrop.in {
    opacity: 0;
}
.modal {
    z-index: inherit !important;
    position: relative;
}

Working Fiddle Example

SideNote 如果您有多个模态，Modal CSS中的上述CSS更改可能会导致其他模态无法正常运行，因此请使用自定义选择器而不是在默认模式选择器中进行更改。
