Javascript jQuery ui自动完成IE 11问题

当我在autocomplete源函数中返回一个大的结果集时，结果不会出现在IE中。使用chrome和Firefox，一切正常

IE控制台不显示任何错误或警告，当我调试代码时，结果变量具有所有值

我尝试分割结果集并设置超时值，但没有成功

这是我的自动完成功能：

 $( "#" + autoCompleteEle ).autocomplete({
    minLength: 2,
    autoFocus: true,
    delay: 1000,
    maxResults: 100,
    timeout: 60000,
    source: function( request, response ) {
        var res = [];
        var resStr  = "";
        var cn = "";
        var owner = "";
        var nrfLocalizedDescrs = "";
        var noResultsLabel = "No Results";

        var roleObj = {};
        var term = request.term.toLowerCase();
        if(term.substr(0,1).indexOf("*") == -1){
            var spinnElement = $("#" + autoCompleteEle ).parent();
            //spinnElement.wrap("<div id='spinnWrappper'></div>");
            initSpinner( spinnElement, "20%", "35%" );

            setTimeout(function () {
                var queryRes = null;
                queryRes = queryRoles(term, clientValue);
                var selRowId = $("#roleGrid").jqGrid("getGridParam", "selrow");
                var system = $("#" + selRowId + "_system").val();
                var roleGrid = $("#roleGrid").jqGrid("getGridParam", "data");
                var roleDnArray = $.map(roleGrid, function (item) { 
                    if( (typeof(item.roleDn) != "undefined") && (typeof(item.system) != "undefined") && item.system.toLowerCase() == system.toLowerCase() ){
                        return item.roleDn.toLowerCase();
                    }   
                });

                for(key in queryRes){
                    if( roleDnArray.indexOf(key.toLowerCase() ) == -1){
                        if (queryRes.hasOwnProperty(key)) {
                            roleObj = queryRes[key];
                            if(typeof(roleObj.map.attr.map.CN) != "undefined"){

在IE debugger DOM viewer中，查看DOM中是否有autocomplete元素。是的，input元素存在并且具有类ui autocomplete input。只有在结果集非常大的情况下才会出现此问题。

    .ui-autocomplete {
       position: absolute;
       top: 100%;
       left: 0;
       z-index: 1000;
