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。

达到预期效果使用，

.modal-dialog {
    width: 41% !important;
}

其他回答

使用下面的脚本:

.modal {
  --widthOfModal: 98%;
  width: var(--widthOfModal) !important;
  margin-left: calc(calc(var(--widthOfModal) / 2) * (-1)) !important;
  height: 92%;

  overflow-y: scroll;
}

在css文件中添加以下内容

.popover{
         width:auto !important; 
         max-width:445px !important; 
         min-width:200px !important;
       }

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;
        }

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>

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%”});
