使用Laravel 4的Typeahead遥控器-我认为单个零件可以工作，但不能一起工作 [英] Typeahead remote with Laravel 4 - Individual pieces working I think, but not working together

问题描述

我对Laravel和PHP比较满意.我正在通过文档和SO/Google学习Laravel.我已经点击了我在这里可以找到的每个预想/laravel问题，但我似乎找不到合适的例子. 这个问题非常接近.我实际上看不到任何明显的差异.但是话又说回来，那个OP也有遥控器的麻烦.

I'm relatively green with Laravel and PHP. I'm learning Laravel by way of the documentation and SO/Google. I've clicked on every typeahead/laravel question I could find here, and I just can't seem to find an example that quite fits. This question comes very close. I actually don't see any glaring differences. But then again, that OP was having trouble with remote as well.

我想我接近了，因为我的各个作品似乎都是单独工作的.让我解释一下...

I think I'm close, as my various pieces seem to be working individually. Let me explain...

我有一个表格...

<div class="input-group form-group" id="ingredients">
    {{ Form::label('ingredients', 'Ingredients') }}
    {{ Form::text('ingredients[]', null, array(
        'class' => 'form-control typeahead',
        'data-provide' => 'typeahead',
        'data-items' => '10',
        'id' => 'ingredients')
    ) }}
</div>

...和脚本...

... with the script...

<script>
    $('.typeahead').typeahead([
        {
            name: 'ingredients',
            remote: '/recipe/create/%QUERY'
        }
    ]);
</script>

remote:指向此路线

Route::get('recipe/create/{query}', 'SearchController@searchIngredients');

哪个指向此控制器方法...

Which points to this controller method...

public function searchIngredients($query)
{
    $data = array();
    $results = Ingredient::select ('name')->where('name', 'LIKE', '%' . $query . '%')->get();
    foreach ($results as $result) :
        $data[] = $result->name;
    endforeach;
    var_dump($data);
    return Response::json($data);
}

当我在表单中输入一些文本时，我确实看到了浏览器请求:

When I enter some text in the form, I do see the browser request:

如果我直接导​​航到远程URL，则确实会看到我的var_dump:

If I navigate directly to the remote URL, I do see my var_dump as I would expect:

例如/recipe/create/s告诉我

array(4) {
    [0] "Sugar"
    [1] "Cheese"
    [2] "Salt"
    [3] "rasins"
}

我显然错过了一些东西，我怀疑这很简单，尽管在那里我也可能错了.当我开始在表单字段中输入内容时，没有下拉菜单.

I'm clearly missing something, and I have a suspicion that it's simple, though I could be wrong there too. When I begin typing in the form field, there is no dropdown.

我以为键入时永远不会调用我的控制器方法，否则我会在每个浏览器请求中看到var_dump，对吗?

I'm thinking my controller method is never being called when typing, or I would be seeing the var_dump with every browser request, right?

如果是这种情况，我在脚本的remote:位处感到不舒服吗?

If that's the case, am I broken at the remote: bit of the script?

推荐答案

尝试将var_dump从控制器中取出-typeahead期望有效的JSON作为响应.

Try taking var_dump out of the controller - typeahead is expecting valid JSON as a response.
