Bootstrap 模式 event.relatedTarget 在下拉菜单中不起作用

如何解决Bootstrap 模式 event.relatedTarget 在下拉菜单中不起作用

我有一个 foreach 循环，它遍历规则列表，每个规则都有一个引导程序下拉菜单来编辑规则。下拉链接应该打开一个模态，它确实如此。

问题在于 event.relatedTarget 始终包含来自第一个下拉项的数据，而不是已单击的实际下拉项。如果我删除下拉菜单并仅使用普通链接，则一切正常。

我在这里做错了什么？

带下拉菜单的循环：

@foreach( $rules as $rule )
    <a href="#" OnClick="event.preventDefault();" role="button" id="dropdownMenuLink{{ $rule->id }}" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" data-offset="-1,8">{{ $rule->name }} <i class="fas fa-caret-down"></i></a><br />

    <ul class="dropdown-menu" aria-labelledby="dropdownMenuLink{{ $rule->id }}">
        <li><a class="dropdown-item" href="#" OnClick="event.preventDefault();" data-toggle="modal" data-target="#editRule" data-id="{{ $rule->id }}" data-name="{{ $rule->name }}">Edit rule</a></li>
    </ul>
@endforeach

模态：

<div class="modal fade" id="editRule" tabindex="-1" role="dialog" aria-labelledby="editRuleCenterTitle" aria-hidden="true">
    <div class="modal-dialog modal-dialog-centered" role="document">
        <div class="modal-content text-white bg-dark">
            <form method="POST" action="#">
                @csrf

                <div class="modal-header">
                    <h5 class="modal-title" id="editRuleCenterTitle">Edit Rule</h5>

                    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                        <span aria-hidden="true">&times;</span>
                    </button>
                </div>

                <div class="modal-body">
                    <div class="form-group row">
                        <div class="col-md-12">
                            <label for="ruleName" class="form-label">Rule name</label>

                            <input id="ruleName" type="text" class="form-control" name="ruleName" required>
                        </div>
                    </div>
                </div>

                <div class="modal-footer">
                    <button type="submit" class="btn btn-primary">Update Rule</button>
                </div>
            </form>
        </div>
    </div>
</div>

脚本：

@section( 'scripts' )
<script>
    $( '#editRule' ).on( 'show.bs.modal',function ( event ) {
        console.log( event.relatedTarget );
        var button = $( event.relatedTarget );
        var id = button.data( 'id' );
        var name = button.data( 'name' );
        var modal = $( this );
        modal.find( '.modal-title' ).text( 'Edit rule: ' + name );
        modal.find( '.modal-body input' ).val( name );
    });
</script>
@endsection
``

解决方法

将您的 foreach 循环包裹在一个带有类下拉列表的 div 中：

@foreach( $rules as $rule )
<div class="dropdown">
    <a href="#" OnClick="event.preventDefault();" role="button" id="dropdownMenuLink{{ $rule->id }}" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" data-offset="-1,8">{{ $rule->name }} <i class="fas fa-caret-down"></i></a><br />

    <ul class="dropdown-menu" aria-labelledby="dropdownMenuLink{{ $rule->id }}">
        <li><a class="dropdown-item" href="#" OnClick="event.preventDefault();" data-toggle="modal" data-target="#editRule" data-id="{{ $rule->id }}" data-name="{{ $rule->name }}">Edit rule</a></li>
    </ul>
</div>
@endforeach
