[英]How to prevent conflicting events (I think) in React?
I'm using react-beautiful-dnd
:我正在使用
react-beautiful-dnd
:
<DragDropContext>
<Droppable>
{(provided, snapshot) => (
<div>
<Draggable><Item with Slider></Draggable>
<Draggable><Item with Slider></Draggable>
<Draggable><Item with Slider></Draggable>
<Draggable><Item with Slider></Draggable>
etc
</div>
)}
</Droppable>
</DragDropContext>
My understanding is that Draggable
will have some variety of event listeners to allow it to detect when it is clicked/clicked and dragged/etc.我的理解是
Draggable
将具有多种事件侦听器,以允许它检测何时单击/单击和拖动/等。
The Slider
component that I'm using will also have similar events (since I assume it provides similar event listeners to Draggable
).我正在使用的
Slider
组件也将具有类似的事件(因为我假设它提供了与Draggable
类似的事件侦听器)。
How can I either:我怎样才能:
react-beautiful-dnd
to ignore events emitted from certain targetsreact-beautiful-dnd
以忽略从某些目标发出的事件or或者
react-beautiful-dnd
doesn't receive an event?react-beautiful-dnd
不接收事件? The screenshot below shows two sliders - (1) a React component ( material-ui
) and (2) an <input type="range" />
component.下面的屏幕截图显示了两个滑块 - (1) 一个 React 组件 (
material-ui
) 和 (2) 一个<input type="range" />
组件。 The normal range works fine (doesn't trigger drag and drop) while the Slider does not.正常范围工作正常(不会触发拖放),而滑块则不然。

The key to accomplish this is to only add the spread {...provided.dragHandleProps}
to the inner div and make sure that {...provided.dragHandleProps}
is NOT on container parent which is usually the div which is the direct child of the <Draggable>
完成此操作的关键是仅将扩展
{...provided.dragHandleProps}
添加到内部 div 并确保{...provided.dragHandleProps}
不在容器父级上,这通常是直接子级的 div <Draggable>
<Droppable droppableId="featureWidgets">
{(provided: any) => (
<div {...provided.droppableProps} ref={provided.innerRef}>
<FeaturesListView>
{featureWidgets.map(({id, type}, index) => {
return (<Draggable key={id} draggableId={id} index={index}>
{(provided) => (
<div
ref={provided.innerRef} {...provided.draggableProps} ///* NO NO not here {...provided.dragHandleProps} */
<div {...provided.dragHandleProps}>drag grip handle</div>
<WidgetRow>
<Slider/>
</WidgetRow>
</div>
)}
</Draggable>);
})}
{provided.placeholder}
</FeaturesListView>
</div>
)}
</Droppable>
