單擊laravel 5上的鏈接發布ajax數據

Question

我是Ajax和laravel 5的新手

我在單擊鏈接時遇到有關傳遞數據的問題，我將向您解釋我要實現的目標。

這是我的html代碼：

//this is the div that i want append with data foreach
<div id="warung-plain">
</div>

//and those code is links that when i click it will send ajax data
@foreach($kategoriwarung_all as $kategoriwarung)
    <li style="padding:5px 0px">
        <a class="kategori-warung" style="text-decoration:none;color:#5ca4a9" href="#">
           {{ $kategoriwarung->nama }}
        </a>
    </li>
 @endforeach

//this is a html code that i want plain in id="warung-plain" after get the foreach data
<div class="row" style="margin:3% 0px 0px 0px" id="">
@foreach($warung_has_kategoriwarungs[$category_fix] as $Warung)
    <div class="col-md-6" style="margin-bottom:0px;min-height:100px">
        <ul class="no-padding" style="display:inline-flex;list-style-type: none;width:100%;">
            <li>
                <img class="img-circle" src="assets/gambar_contoh/foto.jpg" style="height:60px;width:60px">
            </li>
            <li style="padding:0px 0px 0px 15px ;width:100%">
                <p class="heading-toko-font" style="font-size:18px;color:#606060">{{ $Warung->Warung->nama  }}</p>
                <span class="alamat-toko-font" style="font-size:14px;color:#BCBCBC"><?php echo $Warung['Warung']['alamat']; ?></span>
            </li>
        </ul>       
    </div>
@endforeach                        
</div>   

這是我的js

<script>
    $(document).ready(function(){
        $(".kategori-warung").click(function(e){ 
            e.preventDefault();
            var category = $(e.target).text();

            jQuery.ajax({
                type: "POST",
                //after passing data category then system will append 
                //html code to id="warung-plain"
                url: "/ambil_kategori/{category}",
                data: {category: category},
                success: function(res) {
                    $('#warung-plain').load("/warung_plain/{category}");
                }
            });   
            $(".warung").fadeIn("slow").show();
            $("#nama-kategori").html(category);
            $(".warung-semua").hide();  
        });
    });
</script>

這是我的控制器：

public function index()
{   
    $Warungs_all = Warung::paginate(10);
    $kategoriwarung_all = kategoriwarung::all();


    return view('index' , compact('kategoriwarung_all' , 'Warungs_all' ));
}


public function get_warung_by_category($category){

    $category_fix = $category;
    $kategoriwarung_all = kategoriwarung::all();

    foreach($kategoriwarung_all as $kategoriwarung){
        $kategoriwarung->nama;
        $kategoriwarung->id;
        $warung_has_kategoriwarungs[$kategoriwarung->nama] = warung_has_kategoriwarung::where('kategoriwarung_id' , '=' , $kategoriwarung->id)->with(['Warung','kategoriwarung'])->paginate(10);
    }

    return view('daftar_warung' , compact('warung_has_kategoriwarungs' ,'category_fix'));
}

public function warung_plain($category , IndexController $objek){
    $objek->get_warung_by_category($category);
}

最后這是我的路線：

Route::get('/', 'IndexController@index');
Route::post('/ambil_kategori/{category}',    'IndexController@get_warung_by_category');
Route::get('/warung_plain/{category}', 'IndexController@warung_plain');

Answer 1

因為您正在發布帖子，所以我認為您需要令牌。

在這里，您可以閱讀有關該csrf-x-csrf-token的文檔。

總結您需要：

// insert a meta tag to generate a tocken
<meta name="csrf-token" content="{{ csrf_token() }}">

// use the tocken in the header http request
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});

在您的代碼中它將是：

jQuery.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': {{ csrf_token() }}
    }
}).ajax({
    type: "POST",
    //after passing data category then system will append 
    //html code to id="warung-plain"
    url: "/ambil_kategori/{category}",
    data: {category: category},
    success: function(res) {
        $('#warung-plain').load("/warung_plain/{category}");
    }
});

請注意，blade的語法{category}是錯誤的，如果您只有變量或category ，則它應類似於{{ $category }} 。

Answer 2

這里有很多錯誤。 您正在使用發布，但實際上並沒有創建新的資源項目。 其次，您的warung_plain函數什么都不返回？ 你應該對這條路不對勁

/ambil_kategori/{category}

此外，在您的JS中，您不會針對正確的網址發布內容。 您應該發布到（如果出於某種原因要這樣做）：

'/ambil_kategori/'+category

建議您重新閱讀L5文檔
