如何将Web方法添加为Bootstrap Taginput的源？

问题描述

$(document).ready(function () {
             $('[id$=tagsinput]').tagsinput({
                 itemValue: 'value',
                 itemText: 'text',
                 typeahead: {
                     source: function (query) {
                         var str;
                         $.ajax({
                             type: "POST",
                             url: "CityNamesData.asmx/GetCities",
                             contentType: "application/json; charset=utf-8",
                             dataType: "json",
                             success: function (data) {
                                 str = data.d;
                             }
                         });
                         var str1 = $.getJSON(str); 
                          return str1;
                         //var str = $.getJSON('assets/cities.json'); //This line is working fine if we want to retrieve data from json file.
                        
                     }
                 }
             });

//Below code shows tags into the asp.net textbox control
             $('[id$=tagsinput]').tagsinput('add', { "value": 1, "text": "Amsterdam" });
             $('[id$=tagsinput]').tagsinput('add', { "value": 4, "text": "Washington" });
             $('[id$=tagsinput]').tagsinput('add', { "value": 7, "text": "Sydney" });
             $('[id$=tagsinput]').tagsinput('add', { "value": 10, "text": "Beijing" });
             $('[id$=tagsinput]').tagsinput('add', { "value": 13, "text": "Cairo" });
         })

我正在尝试将来自web方法的数据保存到str1中，如下所示

var str1 = $ .getJSON（ str）;

返回str1;

str1以先前在str中保存的格式保存数据。

但是当我有试图返回str1，它没有向文本框显示建议。

str和str1将json数据存储到相同的格式。但它只显示我返回str时的建议。

任何人都可以告诉我如何返回来自WebMethod的数据，以便在文本框中显示建议。

我不知道str1有什么问题。

I am trying to save data coming from web method into str1 as follows
var str1 = $.getJSON(str);
return str1;
str1 saves data in the same format as it was previously saved in str.
But still when I have tried to return str1, its not showing suggestions into the textbox.
str and str1 are storing json data into the same format.But it is only showing suggestions when I am returning str.
Can anyone please tell me how to return this data coming from WebMethod so that it would show suggestions in textbox.
I dont know whats wrong with str1.
