中心模态加载微调器引导程序4

时间：2018-01-12 14:55:06

标签： html bootstrap-modal bootstrap-4

我想要一个模态加载微调器，并在Bootstrap 4的模态对话框中进行测试。但是，我无法将模态水平居中在页面上。如果可能的话，我也希望模态没有边框和透明（所以看起来只有微调器悬停在页面上）

 function modal(){
       $('.modal').modal('show');
       setTimeout(function () {
       	console.log('hejsan');
       	$('.modal').modal('hide');
       }, 3000);
    }

应用这两个类：

.bd-example-modal-lg .modal-dialog{
    display: table;
    position: relative;
    margin: 0 auto;
    top: calc(50% - 24px);
  }

  .bd-example-modal-lg .modal-dialog .modal-content{
    background-color: transparent;
    border: none;
  }

＆＃13;
＆＃13; 
function modal(){
       $('.modal').modal('show');
       setTimeout(function () {
       	console.log('hejsan');
       	$('.modal').modal('hide');
       }, 3000);
    }
＆＃13; 
.bd-example-modal-lg .modal-dialog{
    display: table;
    position: relative;
    margin: 0 auto;
    top: calc(50% - 24px);
  }
  
  .bd-example-modal-lg .modal-dialog .modal-content{
    background-color: transparent;
    border: none;

我知道是旧帖子，但这对我来说似乎是一个更清洁的选择... 

function modal(){
       $('.modal').modal('show');
       setTimeout(function () {
       	console.log('hejsan');
       	$('.modal').modal('hide');
       }, 3000);
    }

使用d-flex和justify-content-center类的Bootstrap 4.x。

<div class="modal fade" id="loadingModal" tabindex="-1" role="dialog">
    <div class="modal-dialog modal-dialog-centered d-flex justify-content-center" role="document">
        <div class="spinner-border" role="status">
            <span class="sr-only">Loading...</span>
        </div>
    </div>
</div>

您可以再删除一个班级。因为modal-dialog是一个弹性框。

text-center + w-100-> justify-content-center 

function modal(){
    $('.modal').modal('show');
        setTimeout(function () {
       	console.log('completed');
       	$('.modal').modal('hide');
    }, 3000);
}
