下面是一个使用Blazor和CSS实现推拉效果的示例代码:
PullPush.razor
:
@pullText
@pushText
@code {
private bool isDragging = false;
private int startX;
private int pullX;
private int pushX;
private string pullText = "Pull";
private string pushText = "Push";
private string pullStyle => $"left: {pullX}px;";
private string pushStyle => $"left: {pushX}px;";
private void StartDrag(MouseEventArgs e)
{
isDragging = true;
startX = (int)e.ClientX;
}
private void Drag(MouseEventArgs e)
{
if (isDragging)
{
int offsetX = (int)e.ClientX - startX;
pullX = offsetX;
pushX = offsetX;
StateHasChanged();
}
}
private void EndDrag()
{
isDragging = false;
pullX = 0;
pushX = 0;
pullText = "Pull";
pushText = "Push";
StateHasChanged();
}
}
.container {
position: relative;
width: 200px;
height: 100px;
background-color: lightgray;
border: 1px solid gray;
overflow: hidden;
}
.pull, .push {
position: absolute;
top: 0;
width: 100px;
height: 100px;
line-height: 100px;
text-align: center;
font-size: 20px;
color: white;
background-color: blue;
transition: left 0.3s ease;
cursor: pointer;
}
.pull {
left: 0;
}
.push {
right: 0;
}
PullPush
组件:
此示例中, 注意:此示例仅演示了基本的推拉效果,您可以根据实际需求进行样式和交互的定制。PullPush
组件包含了两个带有文本的left
样式属性,可以实现元素的推拉效果。当鼠标按下并拖动时,根据鼠标的偏移量更新元素的位置,并通过StateHasChanged
方法通知Blazor进行UI刷新。
