下面由Laravel教學專欄為大家介紹laravel自訂範本指令-tojs ,希望對需要的朋友有幫助！
Blade 允許你自訂指令，你可以使用 directive 方法註冊指令。當 Blade 編譯器遇到該指令時，它將會帶著參數呼叫提供的回呼函數。 blade範本可以透過directive方法來自訂範本指定，
tojs指令主要用於PHP自訂一些資料轉換為js物件方便js呼叫
<?php
namespace App\Providers;
use App\Helpers\ToJs\ToJs;
use Illuminate\Support\Facades\Blade;
use Illuminate\Support\ServiceProvider;
class ToJsServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
//
}
/**
* Register the application services.
*
* @return void
*/
public function register()
{
$this->app->singleton('tojs', function () {
return new ToJs();
});
/*
* The block of code inside this directive indicates
* the chosen javascript variables.
*/
Blade::directive('tojs', function () {
return '<script> window.Laravel = ' . json_encode(app('tojs')->get()) . '</script>';
});
}
}<?php
namespace App\Helpers\ToJs;
use Illuminate\Support\Arr;
class ToJs
{
protected $data = [];
public function put(array $data)
{
foreach ($data as $key => $value) {
$this->data[$key] = value($value);
}
return $this;
}
public function get($key = null, $default = null)
{
if (!$key) return $this->data;
return Arr::get($this->data, $key, $default);
}
public function forget($keys)
{
Arr::forget($this->data, $keys);
return $this;
}
}namespace App\Helpers\ToJs\Facades;
use Illuminate\Support\Facades\Facade;
class ToJsFacade extends Facade
{
/**
* Get the registered name of the component.
*
* @return string
*/
protected static function getFacadeAccessor()
{
return 'tojs';
}
}providers 新增\App\Providers\ToJsServiceProvider::class
aliases 加入'ToJs' => \App\Helpers\ToJs\Facades\ToJsFacade::class,
if (!function_exists('to_js')) {
/**
* Access the javascript helper.
*/
function to_js($key = null, $default = null)
{
if (is_null($key)) {
return app('tojs');
}
if (is_array($key)) {
return app('tojs')->put($key);
}
return app('tojs')->get($key, $default);
}
}在PHP程式碼需要的地方呼叫to_js(['username'=>'test'] );
blade模板直接透過@tojs 就可以在頁面渲染出<script> window.Laravel = {"username":"test "}</script>
