Javascript 将背景色设置为“从另一刀片中的窗体分割”

我的项目包含index.blade.php和create.blade.php。 在create.blade.php中，是一个用于创建index.blade.php中列出的div的表单，通过该表单，我需要传递每个div的背景色，选项为红色、黄色和绿色

我的create.blade.php代码：

<form action="{{url('warehouse')}}" method="post">
@csrf
<label for="name" style="padding-right:20px">Name</label>
<input type="text" id="name" name="name" style="padding-right:50px; margin-bottom:10px" placeholder="Name"><br>
<label for="supplier" style="padding-right:2px">Supplier</label>
<input type="text" id="supplier" name="supplier" style="padding-right:50px; margin-bottom:10px"
    placeholder="Supplier"><br>
<label for="type" style="padding-right:28.5px">Type</label>
<input type="text" id="type" name="type" style="padding-right:50px; margin-bottom:10px" placeholder="Type"><br>
<label for="url" style="padding-right:41.8px">Url</label>
<input type="text" id="url" name="url" style="padding-right:50px; margin-bottom:10px" placeholder="Url"><br>
<label for="color">Color</label>
<select id="selector" name="color">
    <option value="" disabled selected hidden>Please Choose...</option>
    <option value="green">Green (ready for sale)</option>
    <option value="yellow">Yellow (in progress)</option>
    <option value="red">Red (new)</option>
</select>
<br>
<button type="submit" id="kreiraj_dugme_create" onclick="selectBackground()">Create/button>

@foreach ($warehouses as $key => $warehouse)
<div class="brder1" draggable="true" ondragstart="drag(event,{{$key}})" id="{{$key}}">
    <h1 class="ime_palete">{{$warehouse->name}}</h1>
    <a class="link_palete" href="{{$warehouse->url}}" target="_blank">Link</a>
    <a class="edit_palete" href="{{url("warehouse/".$warehouse->id."/edit")}}">Edit</a>
    <a class="show_pallet" href="{{url("warehouse/".$warehouse->id)}}">Show</a>
    <form action="{{url("warehouse/".$warehouse->id)}}" method="post">
        @csrf
        @method('DELETE')
        <button type="submit" class="izbrisiDugme" onclick="remove()">Remove</button>
    </form>
</div>
@endforeach

</div>
<a class="create_palete" href="{{url("warehouse/create")}}">Create</a>

以及我的index.blade.php代码：

<form action="{{url('warehouse')}}" method="post">
@csrf
<label for="name" style="padding-right:20px">Name</label>
<input type="text" id="name" name="name" style="padding-right:50px; margin-bottom:10px" placeholder="Name"><br>
<label for="supplier" style="padding-right:2px">Supplier</label>
<input type="text" id="supplier" name="supplier" style="padding-right:50px; margin-bottom:10px"
    placeholder="Supplier"><br>
<label for="type" style="padding-right:28.5px">Type</label>
<input type="text" id="type" name="type" style="padding-right:50px; margin-bottom:10px" placeholder="Type"><br>
<label for="url" style="padding-right:41.8px">Url</label>
<input type="text" id="url" name="url" style="padding-right:50px; margin-bottom:10px" placeholder="Url"><br>
<label for="color">Color</label>
<select id="selector" name="color">
    <option value="" disabled selected hidden>Please Choose...</option>
    <option value="green">Green (ready for sale)</option>
    <option value="yellow">Yellow (in progress)</option>
    <option value="red">Red (new)</option>
</select>
<br>
<button type="submit" id="kreiraj_dugme_create" onclick="selectBackground()">Create/button>

@foreach ($warehouses as $key => $warehouse)
<div class="brder1" draggable="true" ondragstart="drag(event,{{$key}})" id="{{$key}}">
    <h1 class="ime_palete">{{$warehouse->name}}</h1>
    <a class="link_palete" href="{{$warehouse->url}}" target="_blank">Link</a>
    <a class="edit_palete" href="{{url("warehouse/".$warehouse->id."/edit")}}">Edit</a>
    <a class="show_pallet" href="{{url("warehouse/".$warehouse->id)}}">Show</a>
    <form action="{{url("warehouse/".$warehouse->id)}}" method="post">
        @csrf
        @method('DELETE')
        <button type="submit" class="izbrisiDugme" onclick="remove()">Remove</button>
    </form>
</div>
@endforeach

</div>
<a class="create_palete" href="{{url("warehouse/create")}}">Create</a>

@foreach（$key=>$warehouse的仓库）
{{$warehouse->name}
@csrf
@方法（'DELETE'）
去除
@endforeach

我只需要将“选项”中的“背景色”设置为divbrder1

您可能需要这样做

使用jQuery：

 $("#selector").change(function(){
   $(".brder1").css('background-color', $(this).val());
});

---

您可以将代码放在documentready中。所以代码片段如下所示

$(document).ready(function(){
    $("#selector").change(function(){
        $(".brder1").css('background-color', $(this).val());
    });
});

---

是否希望每个brder1使用不同的背景色播放？是。。我从选项中选择什么来显示该颜色是的，我可以在某处与您联系吗？不太可能：-。。。但我相信你可以从那里接受。。。。
