Laravel 5.1 和 Typeahead.js

Question

我正在尝试在我的 Laravel 5.1 blade 视图中使用 typeahed.js。我试图重新创建 The Basics typeahed 示例，但是在尝试搜索它们时状态没有显示。

这是代码我的主要布局

<html>
<head>
    <title>App Name - @yield('title')</title>
    {{--<link rel="stylesheet" href="{{ URL::asset('assets/js/search.js') }}">--}}
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
    <script type="text/javascript" src="{{ URL::asset('js/bootstrap.min.js') }}"></script>


    {{--<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>--}}


    <script type="text/javascript" src="{{ URL::asset('js/search.js') }}"></script>

    <link href="{{ URL::asset('css/app.css') }}" rel="stylesheet">
    <link href="{{ URL::asset('css/custom.css') }}" rel="stylesheet">

    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no">

    <script src="https://cdnjs.cloudflare.com/ajax/libs/typeahead.js/0.11.1/typeahead.bundle.min.js"></script>





</head>
<body>
@section('sidebar')

@show

<div class="container">
    @yield('content')
</div>
</body>
</html>

我的 blade 视图我正在尝试在

中查看它

@extends('layouts.main')



@section('content')

        <input class="typeahead" type="text" placeholder="States of USA">

        var substringMatcher = function(strs) {
            return function findMatches(q, cb) {
                var matches, substringRegex;

                // an array that will be populated with substring matches
                matches = [];

                // regex used to determine if a string contains the substring `q`
                substrRegex = new RegExp(q, 'i');

                // iterate through the pool of strings and for any string that
                // contains the substring `q`, add it to the `matches` array
                $.each(strs, function(i, str) {
                    if (substrRegex.test(str)) {
                        matches.push(str);
                    }
                });

                cb(matches);
            };
        };

        var states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California',
                      'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii',

                      'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'
        ];

        $('#the-basics .typeahead').typeahead({
                                                  hint: true,
                                                  highlight: true,

                                              },
                                              {

本周早些时候我也做了同样的事情，我使用 Bloodhound 获得了 getting/formatting 和 ajax 结果。这是我的代码：

<input type="text" class="input-sm form-control typeahead-city" id="cities">

和 javascript:

// define the data source
var cities = new Bloodhound({
    datumTokenizer: function(datum) {
         return Bloodhound.tokenizers.whitespace;
    },
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    remote: {
        wildcard: '%QUERY', // this is the replacement on the url
        url: '/citysearch/%QUERY',  // this is the url the request should be made to
        transform: function(response) {
            // convert the response to a object that contains the `value` key
            var results = $.map(response["_embedded"]["city:search-results"], function(city) {
                             return {
                                value: city.matching_full_name,
                                full: city
                          };
                      });
            return results;
        }
    }
});

// Initialize typeahead input with Bloodhound object as the source
$('.typeahead-city').typeahead(null, {
    display: 'value',
    source: cities,
    highlighter: function(item) {
        return "<img src='/img/marker_search.png'>&nbsp;" + item
    },
});

而且我使用了 typeahead.bundle.min.js，其中包含 bloodhound 和 typeahead。
