/* Set given parameter key name as suggestions to the bind text field */
var suggestionToDisplay = [];
var suggestionFound = false;
var datas = [];
$.fn.setSuggestionField = function (option1, option2) {
    var map = {
        17: false,
        32: false,
        77: false
    };
    $(this).autocomplete({
        minLength: 0,
        source: function (request, response) {
            response(suggestionToDisplay);
            suggestionToDisplay = [];
        },
        focus: function () {
            return false;
        },
        select: function (event, ui) {
            var textValue = this.value;
            /* add the selected item */
            var data = ui.item.value;
            /*
             * Replace the hint word with selected data if
             * suggestionFound is true otherwise append to hint word
             */
            if (suggestionFound) {
                textValue = textValue.substring(0, textValue.lastIndexOf("}") + 1);
                for (i = 0; i < datas.length; i++) {
                    if (datas[i].key == data) textValue += "@{" + datas[i].value + "}";
                }
            } else {
                for (i = 0; i < datas.length; i++) {
                    if (datas[i].key == data) textValue += "@{" + datas[i].value + "}";
                }
            }
            this.value = textValue;
            datas = [];
            return false;
        }
    }).keydown(function (e) {
        if (e.keyCode in map) {
            map[e.keyCode] = true;
            var inputLetters = $(this).val();
            if (map[17] && map[32]) {
                datas = option1;
                /* Get the suggestion values for text field */
                suggestionToDisplay = [];
                setSuggestionOptions(inputLetters);
                $(this).autocomplete('search');
            } else if (map[17] && map[77]) {
                datas = option2;
                /* Get the suggestion values for text field */
                setSuggestionOptions(inputLetters);
                $(this).autocomplete('search');
            }
        }
    }).keyup(function (e) {
        if (e.keyCode in map) {
            map[e.keyCode] = false;
        }
    });
}

当此功能绑定到ctrl +“”或ctrl + m的文本字段时，会给出建议。它在Google Chrome，Mozila上正常运行，但在Internet Explorer上ctrl + m可以正常运行，但在ctrl + space上运行不正常。空格，它会显示建议字段，并在我按下空格键后立即添加空间。因此建议字段消失了。如何解决此问题
