When CSS style is added on the class .modalinstead of .modal-dialog, you can then simply change the width of the modal as you want by the following code:

当在类上添加 CSS 样式.modal而不是 时.modal-dialog，您可以根据需要通过以下代码简单地更改模态的宽度：

.modal{
    width: 80%; /* respsonsive width */
    margin-left:-40%; /* width/2) */ 
}

$(function() {
  $("#myDialog").modal("show");
});

.modal-dialog {
  width: 80%;
  margin: auto;
}
.modal{
  width: 80%; /* respsonsive width */
  margin-left:-40%; /* width/2) */ 
}

<div id="myDialog" class="modal fade" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><i class="fa fa-times"></i></button>
        <div class="modal-title" id="Dialog_title">Text Document</div>
      </div>
      <div class="modal-body">

        <div id="my_doc_content"></div>

      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal" onclick="rg.closeDialog('myDialog');">Close</button>
      </div>
    </div>
  </div>
</div>

I always suggest to work with non-builtfiles, working with sources you can take benefits from variables, mixinsand, when needed, add/modifysome default behaviour not explicitly exposed...

我总是建议使用非构建文件，使用可以从变量、mixin 中受益的源代码，并在需要时添加/修改一些未明确公开的默认行为......

so, going to https://github.com/twbs/bootstrap/blob/v4.0.0-alpha.3/scss/_modal.scssyou can see where sizes are defined and add/edit them as you need...

因此，转到https://github.com/twbs/bootstrap/blob/v4.0.0-alpha.3/scss/_modal.scss，您可以看到定义大小的位置并根据需要添加/编辑它们...

// example
@include media-breakpoint-up(lg) {
  .modal-extralg { max-width: $modal-lg * 2; }
}

Just use id:

只需使用标识：

#myDialog {
    width:80%;
}
