function KZ_Loading(config) {
  if (this instanceof KZ_Loading) {
    const domTemplate = '<div class="modal fade kz-loading" data-kzid="@@KZ_Loadin_ID@@" backdrop="static" keyboard="false"><div style="width: 200px;height:20px; z-index: 20000; position: absolute; text-align: center; left: 50%; top: 50%;margin-left:-100px;margin-top:-10px"><div class="progress progress-striped active" style="margin-bottom: 0;"><div class="progress-bar" style="width: 100%;"></div></div><h5>@@KZ_Loading_Text@@</h5></div></div>';
    this.config = {
      content: 'loading...',
      time: 0,
    };
    if (config != null) {
      if (typeof config === 'string') {
        this.config = Object.assign(this.config, {
          content: config
        });
      } else if (typeof config === 'object') {
        this.config = Object.assign(this.config, config);
      }
    }
    this.id = new Date().getTime().toString();
    this.state = 'hide';

    /*显示 */
    this.show = function () {
      $('.kz-loading[data-kzid=' + this.id + ']').modal({
        backdrop: 'static',
        keyboard: false
      });
      this.state = 'show';
      if (this.config.time > 0) {
        var that = this;
        setTimeout(function () {
          that.hide();
        }, this.config.time);
      }
    };
    /*隐藏 */
    this.hide = function (callback) {
      $('.kz-loading[data-kzid=' + this.id + ']').modal('hide');
      this.state = 'hide';
      if (callback) {
        callback();
      }
    };
    /*销毁dom */
    this.destroy = function () {
      var that = this;
      this.hide(function () {
        var node = $('.kz-loading[data-kzid=' + that.id + ']');
        node.next().remove();
        node.remove();
        that.show = function () {
          throw new Error('对象已销毁!');
        };
        that.hide = function () {};
        that.destroy = function () {};
      });
    }

    var domHtml = domTemplate.replace('@@KZ_Loadin_ID@@', this.id).replace('@@KZ_Loading_Text@@', this.config.content);
    $('body').append(domHtml);
  } else {
    return new KZ_Loading(config);
  }
}

基本调用:

var loading = new KZ_Loading('数据加载中。。。');
setTimeout(function () {
  console.log('加载完成!');
  loading.hide();
}, 1000);

自动关闭:

var loading = new KZ_Loading({
  content: '数据加载中。。。',
  time: 2000
});
loading.show();

销毁Loading Dom节点:

 loading.destroy();

ps:下面看下基于JQUERY BOOTSTRAP 最简单的loading遮罩层

<%--loading遮罩层--%>
<div class="modal fade" id="loadingModal" backdrop="static" keyboard="false">
    <div style="width: 200px;height:20px; z-index: 20000; position: absolute; text-align: center; left: 50%; top: 50%;margin-left:-100px;margin-top:-10px">
      <div class="progress progress-striped active" style="margin-bottom: 0;">
        <div class="progress-bar" style="width: 100%;"></div>
      </div>
      <h5 id="loadText">loading...</h5>
    </div>
</div>
<%--loading方法--%>
<script type="text/javascript">
  var loadingTime= 5;//默认遮罩时间
  showLoading = function (loadText) {
    if(!loadText){
      $("#loadText").html(loadText)
    }
    $('#loadingModal').modal({backdrop: 'static', keyboard: false});
  }
  hideLoading = function () {
    $('#loadingModal').modal('hide');
  }
</script>
