在我的应用程序中，我正在进行ajax调用以获取一些数据。我正在显示一个微调器，并通过以下代码阻止ui：

＆＃13;
＆＃13; 
function myFunction() {
  $(".spinner").show();
  $('#shadow').addClass('blocker');
  setTimeout(function() {
    $(".spinner").hide();
    $('#shadow').removeClass('blocker');
  }, 3000);
}
＆＃13; 
.spinner {
  position: absolute;
  right: 45%;
  bottom: 50%;
  z-index: 9999;
}
.shadow {
  z-index: 900
}
.blocker {
  z-index: 1000;
  height: 100%;
  width: 100%;
  background: #000000;
  opacity: 0.3;
  left: 0;
  top: 0;
  position: absolute;
}
＆＃13;

<div id="shadow"></div>

<div id="spinner" class="spinner" style="display: none;">Loading...</div>
＆＃13;
＆＃13;
＆＃13;

此代码正常工作，直到我花费一个链接。如果我在花费任何链接后按下按钮，那么黑色图层不会占据页面的全部高度。

重现的步骤： -

  • 消费任何链接
  • 点击按钮
  • 向下滚动以查看问题。

我尝试使用溢出属性但没有运气。

黑色层如何在所有情况下都达到全高（带链接消耗）？

试试这个.blocker{position: fixed;}

＆＃13;
＆＃13; 
function myFunction() {
  $(".spinner").show();
  $('#shadow').addClass('blocker');
  setTimeout(function() {
    $(".spinner").hide();
    $('#shadow').removeClass('blocker');
  }, 3000);
}
＆＃13; 
.spinner {
  position: absolute;
  right: 45%;
  bottom: 50%;
  z-index: 9999;
}
.shadow {
  z-index: 900
}
.blocker {
  z-index: 1000;
  height: 100%;
  width: 100%;
  background: #000000;
  opacity: 0.3;
  left: 0;
  top: 0;
  position: fixed;/* change absolute to fixed */
}
