Question

我的sidebar.blade.php中有一个选择框/下拉列表查看：

    {!! Form::open(array('method'=>'patch','route'=>'search')) !!}
    {!! Form::select('search',$categories,null,array_merge(['class'=>'postform ts-select'],['placeholder'=>'Select Category'],['id'=>'search'],['name'=>'search'])) !!}
    <div class="row">
        <div class="col-xs-12 col-sm-4 col-md-3 col-centered" style="margin-top: 15px">
            {!! Form::submit('Search', array('class'=>'blog-read ts-button')) !!}
        </div>
    </div>
    {!! Form::close() !!}

选择框从模型中接收其值 - ＆gt; Blog.php：

public static function getCategories()
{
    return self::groupBy('category')->lists('category', 'category');
}

在BlogController.php上：

public function getIndex()
{

    $mostRecommended = \App\Blog::mostRecommended();
    $last = \App\Blog::lastPosts();
    $categories = \App\Blog::getCategories();
    //echo'<pre>';
    //dd($mostRecommended);
    return View('blog::index', array('title' => "Welcome ", 'last' => $last, 'mostRecommended' => $mostRecommended, 'categories' => $categories));

}

public function search($category)
{
    $query = Request::get('search');
    $articles = DB::table('blog')->where('category', '=', $query);
    $mostRecommended = \App\Blog::mostRecommended();
    $last = \App\Blog::lastPosts();
    $categories = \App\Blog::getCategories();

    return View('blog::index', array('title' => $query, 'articles' => $articles, 'last' => $last, 'mostRecommended' => $mostRecommended, 'categories' => $categories));
}

路线：
Route::controller('/blog', '\Serverfireteam\blog\BlogController');

//下线不起作用（很明显）
Route::get('/blog/search',['as'=>'search','uses'=>'Serverfireteam\blog\BlogController@search']);

我的主要内容（显示的帖子列表）通过index.blade.php迭代查看：
@foreach($last as $post)
这适用于所有博客。我需要使用下拉/选择框使其动态化。我确信我需要AJAX（但这是我的第一个项目，我很无能）

这是我尝试过的一小部分样本：

Filter with dropdown Laravel

Laravel Ajax dropdown filter

Laravel 5.2 filter with dropdownlist

laravel 5.2 - search function

Get selected text from a drop-down list (select box) using jQuery

我知道我很亲近，这是我在这里摧毁我的经验不足。

我的问题：请，在哪里我搞砸了吗？我在这个问题上花了好几天。

** 更新 在这里，我更新了我的代码以尝试其他内容;请看下面的

<div id="categories-6" class="widget widget_categories">
    <div class="title-widget"><h3>Categories</h3></div>
    <label class="screen-reader-text" for="cat">Categories</label>

    {!! Form::open(array('method'=>'patch','route'=>'search')) !!}
    {!! Form::select('search',$categories,null,array_merge(['class'=>'postform ts-select'],['placeholder'=>'Select Category'],['id'=>'search'],['name'=>'search'])) !!}
    <div class="row">
        <div class="col-xs-12 col-sm-4 col-md-3 col-centered" style="margin-top: 15px">
            {!! Form::submit('Search', array('class'=>'blog-read ts-button')) !!}
        </div>
    </div>
    {!! Form::close() !!}

</div>

这是我目前在index.blade.php上的一个脚本

<script>

    $('#search').on('change', function () {
        var category = $(this).val();
        var base_url = $({!! json_encode(url('/')) !!}).val;
        $.ajax({
            url: base_url + "/blog/search/" + category,
            dataType : "json",
            success: function (data) {
                $('#inner-container').html(data.html); //here container is the wrapper of index view
            }
        });
    });
</script>

以下是我的BlogController.php的更新资料

public function getIndex()
{

    $mostRecommended = \App\Blog::mostRecommended();
    $last = \App\Blog::lastPosts();
    $categories = \App\Blog::getCategories();
    //echo'<pre>';
    //dd($mostRecommended);
    return View('blog::index', array('title' => "Welcome ", 'last' => $last, 'mostRecommended' => $mostRecommended, 'categories' => $categories));

}

最后，routes.php

Route::get('/blog/search/{category}', <br>
['a s'=>'search','uses'=>'Serverfireteam\blog\BlogController@search']);

以下是我收到的错误

ErrorException in UrlGenerationException.php line 17:
