简介 Laravel 简单实现Ajax滚动加载示例_php实例_

开发H5项目的时候我们总是需要用到下拉滚动刷新的方式加载页面。这里用 Laravel 实现一下,直接上代码:

创建模型

这里我们不妨创建一个 文章(Post)模型, 并且生成测试数据 50 条吧。

 php artisan make:model -m

模型Post.php

 namespace App; use Illuminate\Database\Eloquent\Model; class Post extends Model { public $fillable = ['title','description']; } 

迁移文件

 use Illuminate\Database\Schema\Blueprint; use Illuminate\Database\Migrations\Migration; class CreatePostTable extends Migration { /** * Run the migrations. * * @return void */ public function up() { Schema::create('posts', function (Blueprint $table) { $table->increments('id'); $table->string('title'); $table->text('description'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { Schema::drop("posts"); } } 

测试数据 ModelFactory.php

 $factory->define(App\Post::class, function (Faker\Generator $faker) { return [ 'title' => $faker->sentence, 'description' => $faker->paragraph, ]; });

填充

call(UsersTableSeeder::class); factory(App\Post::class, 50)->create(); } } 

路由

 Route::get('my-post', 'PostController@myPost');

控制器

 namespace App\Http\Controllers; use Illuminate\Http\Request; use App\Http\Requests; use App\Post; class PostController extends Controller { public function myPost(Request $request) { $posts = Post::paginate(6); if ($request->ajax()) { $view = view('data',compact('posts'))->render(); return response()->json(['html'=>$view]); } return view('my-post',compact('posts')); } } 

视图文件 resources/view/my-post.php

Laravel 分页滚动加载

Laravel 分页滚动加载


@include('data')

resources/view/data.php

 @foreach($posts as $post) 

{{ $post->title }}

{{ str_limit($post->description, 400) }}


@endforeach

效果:
