引导标记预先输入输入未使用 jQuery ajax 填充菜单答案

【问题标题】：Bootstrap tag typeahead input not populating menu with jQuery ajax引导标记预先输入输入未使用 jQuery ajax 填充菜单
【发布时间】：2017-03-30 03:52:18
【问题描述】：

我正在使用引导标签 (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 sn-p。它正在从服务器获取数据，但没有处理。请告诉我如何解决这个问题？

我已经包含了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',

        //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',

                                replace: function (string) {

你能加个fiddle/snippet吗？

【解决方案1】：

问题在于覆盖方法，如 toString()、replace() 和数据元素分配。

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