Bootstrap标签预输入输入没有使用jQuery ajax填充菜单

Question

我使用bootstrap标签（https://github.com/bootstrap-tagsinput/bootstrap-tagsinput）来填充一些标签。我正在使用jQuery 3和Bootstrap 3.下面是代码片段。它从服务器获取数据但不处理。你能告诉我如何解决这个问题吗？

我已添加https://github.com/twitter/typeahead.js和https://github.com/bootstrap-tagsinput/bootstrap-tagsinput以及相应的CSS

function attachOrgRoleTypeAhead(){
    console.log('attachOrgRoleTypeAhead called');
    $('.roletag').tagsinput({
        tagClass:'form-control input-sm',
        //itemValue: 'rolename',
        //itemText: 'rolename',
        //display: 'rolename',
        allowDuplicates: false,
        freeInput: false,
        typeaheadjs: {
            displayKey: 'text',
            afterSelect: function(val) { this.$element.val(""); },
            source: function (query, process,asynchProcess){
                var typeaheadData = {};
                var rolesdata = {};
                var $items = new Array;
                rolesdata.orgid= $('#orgidselector').find("option:selected").val();
                rolesdata.query=query;
                $.ajax({
                    url: ctx+'organization/findRoles.json',
                    dataType: "json",
                    type: "POST",

                                replace: function (string) {

问题在于重写方法，如toString（），replace（）和数据元素分配。

function attachOrgRoleTypeAhead(){
        console.log('attachOrgRoleTypeAhead called');
