Bootstrap表加载进度条覆盖

Question

我的HTML和分页中有一个表，用ajax加载下一页。 在加载数据时，我希望用Bootstrap进度条覆盖div。

＆＃13;

＆＃13;

function loadingTable(divID) {

	var html = " <div class='table-loading-overlay'>"
		+ " <div class='table-loading-inner'>"
		+ "<div class=\"col-xs-4 col-xs-offset-4\">"
		+ "<div class=\"progress\"> "
		+ "<div class=\"progress-bar progress-bar-striped progress-bar-streit active\" role=\"progressbar\" aria-valuenow=\"100\" aria-valuemin=\"0\" aria-valuemax=\"100\" style=\"width: 100%\">"
		+ "        <span class=\"sr-only\">Loading...</span>"
		+ "    </div>"
		+ "    </div>"
		+ " </div>"
		+ " </div>"
		+ " </div>";
	$('#' + divID).append(html);
}
function prevPage(){}
function nextPage(){}

＆＃13;

.table-loading-inner {
    width: 100%;
    height: 100%;
}
.table-loading-overlay {
    width: 100%;
    height: 100%;
    position: relative;
    display: block;
    z-index: 10;
    background:  #000000;
    z-index: 100;
    opacity: 0.5;
}

＆＃13;

如何让table-loading-overlay超过桌子？ 由于表格可以在HTML中无处不在，我无法使用绝对位置...

Answer 1

如果您不想使用绝对定位的div，可以给父div一个固定的位置。哪个应该也可以。表格在文档中的位置无关紧要。

以下是具有固定定位父级的示例。

function loadingTable(divID) {

  var html = " <div class='table-loading-overlay'>"
  + " <div class='table-loading-inner'>"
  + "<div class=\"col-xs-4 col-xs-offset-4\">"
  + "<div class=\"progress\"> "
  + "<div class=\"progress-bar progress-bar-striped progress-bar-streit active\" role=\"progressbar\" aria-valuenow=\"100\" aria-valuemin=\"0\" aria-valuemax=\"100\" style=\"width: 100%\">"
  + "        <span class=\"sr-only\">Loading...</span>"
  + "    </div>"
  + "    </div>"
  + " </div>"
  + " </div>"
  + " </div>";

  $('#' + divID).append(html);
  $('.table-loading-overlay').css('height', $('#' + divID).height() + 'px');
  $('.table-loading-inner').css('padding-top', ($('#' + divID).height() / 2) + 'px');
}
function prevPage(){}
function nextPage(){}

.table-loading-overlay {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  z-index: 10;
  background:  #000000;
  opacity: 0.5;
}

.table-loading-inner {
  width: 100%;
  height: 100%;
}
