Laravel，按下按钮时传递值

Question

按下按钮时弹出一个模态。问题是，如何将值传递给模态？

我的表格如下图所示。正如您所看到的，每行都有不同的ID。我想在按下按钮

后获取特定行的ID

我的代码：

import threading
import time

# Lock to serialize console output
output = threading.Lock()

def threadfunc(a,b):
    for i in range(a,b):
        time.sleep(.01) # sleep to make the "work" take longer
        with output:
            print(i)

# Collect the threads
threads = []
for i in range(10,100,10):
    # Create 9 threads counting 10-19, 20-29, ... 90-99.
    thread = threading.Thread(target=threadfunc,args=(i,i+10))
    threads.append(thread)

# Start them all
for thread in threads:
    thread.start()

# Wait for all to complete
for thread in threads:
    thread.join()

您还需要循环模式，但在单独的视图中，需要从id $cmp调用var才能动态分配HTML id模态和触发按钮：

@foreach($company as $cmp)
<tr>
  <td>{{ $cmp->number }}</td>
  <td>{{ $cmp->name}}</td>
  <td>  <a type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#modal{{$cmp->id}}" </td
</tr>
@include('path.modal')//Path of the view of a modal
@endforeach

在另一个视图中：

<!-- modal.blade.php -->
<div class="modal fade" id="modal{{$cmp->id}}"role="dialog">
    <div class="modal-dialog">
        <div class="modal-content">
         ...
        </div>
    </div>
</div>

我假设您使用Bootstrap作为布局。 Documentation建议您绑定data-属性以将值传递给模态。 您可以使用jQuery来处理show.bs.modal事件。

您应该为按钮添加唯一标识符。例如data-modal-id。像这样：

@foreach($company as $cmp)
<tr>
     <td>{{ $cmp->number }}</td>
     <td>{{ $cmp->name }}</td>
     <td>
        <button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal" data-modal-id="{{ $cmp->number }}">Button</button>
    </td>
</tr>
@endforeach

在你的javascript中：

$('#myModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget);
  var modal_id = button.data('modal-id');;
  var modal = $(this);
  // do whatever you want with your modal and modal_id
});
