設置bootstrap modal模態框的寬度和寬度

轉載: https://blog.csdn.net/zsg88/article/details/70882370

(1)修改寬度能夠經過修改modal中的modal-dialog這個div寬度實現

 

<div class="modal-dialog" style="width:600px">

 

(2) 修改高度和寬度最好的辦法是修改modal-body中添加的控件，設置控件的大小，modal會自動適應。

例如

 

<div class="modal fade in" id="_modalDialog" tabindex="-1" role="dialog" aria-labelledby="modalLabel"
     style="display: block;">
  <div class="modal-dialog" role="document" style="width: 680px;">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span>
        </button>
        <h4 class="modal-title" id="modalLabel">選擇移動到的目錄</h4></div>
      <div id="_modalDialog_body" class="modal-body">
            <!--  設置這個div的大小，超出部分顯示滾動條 -->
        <div id="selectTree" class="ztree" style="height:300px;overflow:auto; ">
        </div>

      </div>
      <div class="modal-footer">
        <button type="submit" class="btn btn-primary">肯定</button>
        <button type="button" class="btn btn-default" data-dismiss="modal">關閉</button>
      </div>
    </div>
  </div>
</div>
