) { clickX.push(x); clickY.push(y); clickDrag.push(dragging); } 可以看到，这里分别用三个数组clickX,clickY及clickDrag...) { clickX.push(x); clickY.push(y); clickDrag.push(dragging); clickColor.push(curColor); } 而在redraw的方法中...并且也要更新redraw方法，更新后的addClick,redraw代码如下： function addClick(x, y, dragging) { clickX.push(x); clickY.push...(y); clickDrag.push(dragging); clickColor.push(curColor); clickSize.push(curSize); } var radius; var...用clickTool记录用户选择的工具种类，curTool则为当前用户选择的工具，addClick的方法如下： function addClick(x, y, dragging) { clickX.push

react-dnd 从入门到手写低代码编辑器

我们判断下，如果是在 dragging 就设置一个 dragging 的 className。...'box dragging' : 'box'} style={ { background: props.color || 'blue'} }> } 然后添加 dragging...的样式： .dragging { border: 5px dashed #000; box-sizing: border-box; } 测试下：确实，这样就给拖拽中的元素加上了对应的样式。...但是依然要捕获 dragging 状态。...样式如下： .dragging { border-style: dashed; background: #fff; } 效果是这样的：这样，拖拽排序就完成了。

首先，我们定义一些变量来跟踪鼠标的状态和位置： const tool = new paper.Tool(); var lastPoint = null; var dragging = false; var...lastViewCenter; 接着，定义鼠标事件的处理函数： tool.onMouseDown = (event) => { lastPoint = event.point; dragging...= true; }; tool.onMouseDrag = (event) => { if (dragging && lastPoint) { lastViewCenter = paper.view.center...lastPoint = event.point.add(paper.view.center.subtract(lastViewCenter)); } }; tool.onMouseUp = () => { dragging
