Laravel Livewire wire:单击not wire

Question

我正在使用bumbummen99 shopping cart开发一个基于Laravel和Livewire的电子商务平台。我的问题是，我只能向购物车添加项目，但由于某些原因，我无法更新(增加或减少)数量，从购物车中删除项目。I have no error in the console，则在单击这两个按钮时不会发生任何网络活动。I have checked that all the HTML is enclosed in one <div>.我已经查看了其他几个页面(here，here，here)，但没有成功。我还试着更改不工作的导线:单击以遵循导线的格式:单击正在工作的addToCart，这也没有帮助。任何帮助都是非常感谢的。

这是我的产品列表

@extends('layouts.app')

@section('template_linked_css')
<link href="{{asset('front/css/cart.css')}}" rel="stylesheet">

@endsection

@section('content')
<main class="bg_gray">
    @livewire('cart-listing')
</main>
@endsection

下面是我的CartListing组件：

use App\Models\Service;
use Gloudemans\Shoppingcart\Facades\Cart;
use Livewire\Component;

class CartListing extends Component
{
public $products;
public array $quantity = [];

public function mount()
{
    $this->products = Cart::content();
    foreach ($this->products as $product) {
        $this->quantity[$product->id] = 1;
    }
}

public function addToCart($product_id)
{
    $product = Product::findOrFail($product_id);
    Cart::add(
        $product->id,
        $product->name,
        $this->quantity[$product_id],
        $product->price
    );

    $this->emit('cart_updated');
}

public function increase($rowId){
    Cart::update($rowId, 1);
    $this->emit('cart_updated');
}

public function decrease($rowId){
    Cart::update($rowId, -1);
    $this->emit('cart_updated');
}

public function deleteItem($rowId){
    Cart::remove($rowId);
    $this->emit('cart_updated');
}

public function render()
{
    $cart = Cart::content();
    $cart_count = Cart::content()->count();
    $cart_total = Cart::subtotal();

    return view('livewire.cart-listing', compact('cart', 'cart_count', 'cart_total'));
}



}

这是我的livewire购物车列表视图：

    <div class="container margin_30">

我的layouts.app也有livewire链接：

<head>
    @livewireStyles
</head>
<body >
@livewireScripts
</body>

如果要将字符串传递给wire:click方法，则应使用单引号将其封装，如下所示

wire:click="increase('{{$product->rowId}}')"
