需要将输入值传递给 AlpineJS 中的另一个 DIV

Question

我需要将输入值传递给模态，但我无法使用外部参照来完成。这是正确的做法吗？

<div x-data="orderSearch()" class="container mt-2 mx-auto" x-ref="root">
        <div class="grid grid-cols-1 sm:grid-cols-1 md:grid-cols-2 lg:grid-cols-2 mt-2 mb-3">
           <div class="card m-1 p-1 cursor-pointer border border-gray-400 rounded-lg hover:shadow-md hover:border-opacity-0 transform hover:-translate-y-1 transition-all duration-200 bg-green-200">
              <div class="flex flex-row w-full py-2 px-2 m-1 text-sm text-green-800"  x-data="{ qty: '', val: '', total: ''}" x-effect="total = qty * val">

                 <input class="field shadow appearance-none border rounded w-1/3 py-2 px-2 my-1 mx-1 text-gray-700 leading-tight focus:outline-none focus:shadow-outline" id="valorcompra" type="text" placeholder="Valor" autofocus  x-model.number="qty" x-ref="valorcompra" @keydown.enter="fetchOrder('buy',$refs.quantidadecompra.value,$refs.valorcompra.value)">

        <!-- Dialog (full screen) -->
        <div class="absolute top-0 left-0 flex items-center justify-center w-full h-full" style="background-color: rgba(0,0,0,.5);" x-show="modal">
           <!-- A basic modal dialog with title, body and one button to close -->
           <div class="h-auto p-4 mx-2 text-left bg-white rounded shadow-xl md:max-w-xl md:p-6 lg:p-8 md:mx-0">
              <div class="mt-3 text-center sm:mt-0 sm:ml-4 sm:text-left">

                 <div class="mt-2">
                    <p class="text-sm leading-5 text-gray-500" x-text="'Deseja cadastrar a ordem de venda?'">                           
                    </p>
                 </div>
                 
              </div>
              <!-- One big close button.  --->
              <div class="mt-4 flex justify-between">
                 <div class="cancela px-4 bg-red-400 p-3 rounded-lg text-white hover:bg-red-600" @click="modal=false">Cancelar</div>
                 <div class="ok px-4 bg-green-400 p-3 rounded-lg text-white hover:bg-green-600" @click="fetchOrder('sell',$refs.quantidadevenda.value,$refs.valorvenda.value)">Confirmar</div>
              </div>
           </div>
        </div>
        <!-- fim modal div -->
     </div>

必须在此处读取输入值：

<div class="ok px-4 bg-green-400 p-3 rounded-lg text-white hover:bg-green-600" @click="fetchOrder('sell',$refs.quantidadevenda.value,$refs.valorvenda.value)">Confirmar</div>

我试了两天找不到这个答案，但我找不到。

你能帮帮我吗？

Answer 1

我尝试了 $store 解决方案并且成功了：

<script>
     const element = document.querySelector("#valorvenda")
     element.addEventListener('change', (event) => {            
        const quantidadevenda = document.querySelector("#quantidadevenda").value            
        Alpine.store('venda', {
        valorcompra: document.querySelector("#valorcompra").value,
        quantidadecompra:quantidadevenda,
        valorvenda: event.target.value,
        quantidadevenda: quantidadevenda,
        })
        console.log(Alpine.store('fields').valorvenda);
     })
 </script>

这就像一个状态管理，工作正常！

谢谢大家
