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
<"htmlcode">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
<!DOCTYPE html> <html> <head> <title>Laravel 分页滚动加载</title> <script src="/UploadFiles/2021-04-02/jquery.min.js">resources/view/data.php
@foreach($posts as $post) <div> <h3><a href="">{{ $post->title }}</a></h3> <p>{{ str_limit($post->description, 400) }}</p> <div class="text-right"> <button class="btn btn-success">Read More</button> </div> <hr style="margin-top:5px;"> </div> @endforeach效果:
