我如何改变Twitter引导模式框的默认宽度?

我尝试了以下方法:

   <div class="modal hide fade modal-admin" id="testModal" style="display: none;">
        <div class="modal-header">
          <a data-dismiss="modal" class="close">×</a>
          <h3 id='dialog-heading'></h3>
        </div>
        <div class="modal-body">
            <div id="dialog-data"></div>
        </div>
        <div class="modal-footer">
          <a data-dismiss="modal" class="btn" >Close</a>
          <a class="btn btn-primary" id="btnSaveChanges">Save changes</a>
        </div>
    </div>

这段Javascript:

    $('.modal-admin').css('width', '750px');
    $('.modal-admin').css('margin', '100px auto 100px auto');
    $('.modal-admin').modal('show')

结果不是我预料的那样。模态的左上角位于屏幕的中心。

有人能帮帮我吗?有人试过吗?我想这是一件很平常的事。

下面是通过javascript设置模式弹出宽度和屏幕左侧位置的代码。

$ (' # openModalPopupId ') . css({“宽度”:“80%”,“左”:“30%”});

尝试以下内容(参见jsfiddle示例:http://jsfiddle.net/periklis/hEThw/1/)

<a class="btn" onclick = "$('#myModal').modal('show');$('#myModal').css('width', '100px').css('margin-left','auto').css('margin-right','auto');" ref="#myModal" >Launch Modal</a>
<div class="modal" id="myModal" style = "display:none">
  <div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Modal header</h3>
  </div>
  <div class="modal-body">
    <p>One fine body…</p>
  </div>
  <div class="modal-footer">
    <a href="#" class="btn">Close</a>
    <a href="#" class="btn btn-primary">Save changes</a>
  </div>
</div>

基于较少的解决方案(无js) Bootstrap 2:

.modal-width(@modalWidth) {
    width: @modalWidth;
    margin-left: -@modalWidth/2;

    @media (max-width: @modalWidth) {
        position: fixed;
        top:   20px;
        left:  20px;
        right: 20px;
        width: auto;
        margin: 0;
        &.fade  { top: -100px; }
        &.fade.in { top: 20px; }
    }
}

然后无论你想指定一个模态宽度:

#myModal {
    .modal-width(700px);
}

我使用了SCSS和全响应模态:

.modal-dialog.large {
    @media (min-width: $screen-sm-min) { width:500px; }
    @media (min-width: $screen-md-min) { width:700px; }
    @media (min-width: $screen-lg-min) { width:850px; }
}

you can use any prefix or postfix name for modal. but you need to make sure that's should use everywhere with same prefix/postfix name.    

body .modal-nk {
        /* new custom width */
        width: 560px;
        /* must be half of the width, minus scrollbar on the left (30px) */
        margin-left: -280px;
    }

body .nk-modal {
            /* new custom width */
            width: 560px;
            /* must be half of the width, minus scrollbar on the left (30px) */
            margin-left: -280px;
        }

对于Bootstrap 3，这里是如何做到这一点。

在HTML标记中添加一个模态范围样式(从Bootstrap 3文档中的示例改编而来)

<div class="modal fade modal-wide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h4 id="myModalLabel" class="modal-title">Modal title</h4>
      </div>
      <div class="modal-body">
        <p>One fine body&hellip;</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->

并添加以下CSS

.modal-wide .modal-dialog {
  width: 80%; /* or whatever you wish */
}

现在不需要在Bootstrap 3中覆盖margin-left来让它居中。
