treeMultiselect 去掉勾选项

场景描述：弹窗，显示树形结构，节点层次可变（可只有一级节点，也可是多级节点），限制只能选择一个节点！

1、修改jquery.tree-multiselect.min.js 文件

2、前台页面

参考代码：

<!--耗材分类弹出框-->
<div class='popupWindow' id="itemTypeView">
    <ul>
        <li class="popupWindow-header">
            <div class="titleName" id="titleName">@T("Consumable_type")</div>
            <div class="close">×</div>
        </li>
        <li>
            <div class="popupWindow-content">
                <div class="form-group col-xs-12 popupWindow-tree" style="overflow-y: auto;overflow-x: hidden;max-height: 410px;">
                    <select id="test-select" multiple="multiple" class="treeCheckbox"></select>
                </div>
            </div>
        </li>
        <li>
            <div class="popupWindow-footer">
                <button type="button" class="btn btn-primary" onclick="buttonLoading(this)" autocomplete="off" id="btn_save" data-bind="click:saveItemTypeClick">@T("op_save")</button>
                <button type="button" class="btn btn-default" id="btn_cancel" data-bind="click:closeItemTypeClick">@T("op_cancel")</button>
            </div>
        </li>
    </ul>
</div>

3、调用

参考代码：

    //选择耗材分类
    this.selectItemType = function () {
        //初始化树
        var $select = $('#test-select');
        var div = $select.parent();
        var param = {
            itemtypecode: self.form.itemtypecode()
        }
        $.ajax({
            type: "POST",
            url: self.urls.getitemtype,
            data: { data: JSON.stringify(ko.toJS(param)) },
            beforeSend: function () {
                showLoading();
            },
            success: function (d) {
                if (d.result == "error") {
                    console.log(d.message);
                    $(div).html(com.getLocalization(self.sourceName, "Data loading failure."));
                } else {
                    $select.html("");
                    $(div).html("").append($select);
                    var treeData = com.parseJson(d);
                    for (var i = 0; i < treeData.length; i++) {
                        var treenode = treeData[i];
                        var $option = $('<option value="' + treenode.treeNodecode + '" data-parent-code="' + treenode.treeNodeParentPathCode + '" data-section="' + treenode.treeNodeParentPathText + '" class="float-left"  ' + ($.trim(treenode.checkState) == "" ? '' : 'selected="' + treenode.checkState + '"') + '>' + treenode.treeNodetext + '</option>');
                        if (treenode.treeNodeParentPathCode == "0") {
                            $option = $('<option value="' + treenode.treeNodecode + '" data-parent-code="' + treenode.treeNodeParentPathCode + '" data-section="' + treenode.treeNodetext + '" class="float-left"  ' + ($.trim(treenode.checkState) == "" ? '' : 'selected="' + treenode.checkState + '"') + '></option>');
                        }
                        $(div).find('#test-select').append($option);
                    }
                    var treeObject = $select.treeMultiselect({ enableSelectAll: false, sortable: true, searchable: true, onChange: treeChange })[0];
                    $('#test-select').closest('.popupWindow').css('top', ($(window).height() - $('#test-select').closest('.popupWindow').height()) / 2 + "px");
                    function treeChange(options, add, remove) {
                        if (add.length > 0) {
                            $.each($("#test-select option"), function (i, e) {
                                if (e.value != add[0].value) {
                                    //去掉树节点的勾选项
                                    treeObject.removeItem($(e).attr("data-key"));
                                }
                            })
                        }
                    }
                }
            },
            error: function (d) {
                NotifyDanger(d.message);
            },
            complete: function () {
                hideLoading();//关闭特效
            }
        });
        showNormalWindow('itemTypeView');
    }
    //保存耗材分类
    this.saveItemTypeClick = function () {

        ///获取选择的药效分类信息
        var itemtypenames = "", itemtypecodes = "";
        var count = parent.$("#test-select option").length;
        $.each(parent.$("#test-select").get(0).options, function (i, e) {
            if (e.text != "") {//子节点
                itemtypenames += e.innerHTML + ",";
                itemtypecodes += e.value + '_0' + ",";
            } else {
                itemtypenames += $(e).attr("data-section") + ",";
                itemtypecodes += $(e).attr("value") + '_0' + ",";
            }
        })
        if (self.form.itemtypecode().trim() != "") {
            var deleteitemtypecode = $.map(self.form.itemtypecode().split(','), function (e, i) {
                var code = e.substring(0, e.length - 2);
                if (itemtypecodes.indexOf(code) == -1) {
                    return code
                }
            })
            $.each(deleteitemtypecode, function (i, e) {

        self.form.itemtypecode(itemtypecodes.substring(0, itemtypecodes.length - 1));

        self.closeItemTypeClick();
    }
    //关闭耗材分类弹窗
    this.closeItemTypeClick = function () {
        hidePopupWindow('itemTypeView');
    }

4、数据转换

            string itemtypecode = d.itemtypecode == null ? "" : ((string)d.itemtypecode.ToString()).Trim();

            try
            {

                List<string> selectedItemTypeCoce = new List<string>();
                if (!string.IsNullOrEmpty(itemtypecode) && itemtypecode != "[]")
