I visit this site can support IE8+. But when I download https://cdn.jsdelivr.net/npm/gasparesganga-jquery-loading-overlay@2.1.7/dist/loadingoverlay.min.js, it will not work in my webpage.

in my jsp

 <!--[if lt IE 10]>
<script src="<%=path%>/js/html5shiv.min.js"></script>

<script>
    if (!Array.prototype.indexOf)
    {
    Array.prototype.indexOf = function(elt /*, from*/)
    {
    var len = this.length >>> 0;

    var from = Number(arguments[1]) || 0;
    from = (from < 0)
         ? Math.ceil(from)
         : Math.floor(from);
    if (from < 0)
      from += len;

    for (; from < len; from++)
    {
      if (from in this &&
          this[from] === elt)
        return from;
    }
    return -1;
    };
    }
