@inject IJSRuntime jsRuntime

<div @onmousedown="StartDrag" @ontouchstart="StartDrag" @onmousemove="Drag" @ontouchmove="Drag" @onmouseup="EndDrag" @ontouchend="EndDrag">
    <!-- 拖放元素的内容 -->
</div>

@code {
    private bool isDragging = false;

    private void StartDrag(MouseEventArgs e)
    {
        isDragging = true;
        e.PreventDefault();
    }

    private void Drag(MouseEventArgs e)
    {
        if (isDragging)
        {
            e.PreventDefault();
            // 处理拖放逻辑
        }
    }

    private void EndDrag(MouseEventArgs e)
    {
        isDragging = false;
        e.PreventDefault();
    }
}
