Nuke UI

何时使用

Mask 是一个简单的遮罩层,常用于展示上层的对话框、提示等

设计思路

新增 web 端支持

注意 weex < 0.15 的安卓客户端,mask 可能存在兼容性问题,请慎用

Mask 在 native 端封装了 mask 组件,在 web 端使用 View 封装,因此如果要实现遮挡全屏的效果,对组件层级和样式书写有如下要求:

  • 页面根节点不能有任何 padding、margin、border 样式 (确保边缘不漏出来)
  • Mask 组件必须是根节点的最后一个子元素 (确保 View 堆叠顺序)

API

参数说明类型默认值
style样式objectobj
animate显示时是否开启动画booleantrue
effect显示的动画效果,animate = true 时生效,枚举值可选:ease-in,ease-in-out,ease-out,linear,cubic-bezierstring'ease-in-out'
maskClosable能否点击空白区域关闭booleanfalse
duration动画时长,默认 200(单位是 ms)number200
contentStyle内容 style, 如果 Mask 的Children 数量超过1个,可能需要使用。参见如下解释obj

关于 contentStyle

如果 Mask 标签内部不止 1 个子组件,默认我们会在 children 外面再包一层 View,contentStyle 为了控制这层 View 的样式。

实例方法:

  • this.refs.myMask.show() : 显示浮层
  • this.refs.myMask.hide() : 关闭浮层

使用方法

  • 安装
// 切换到你的 rax 项目中
tnpm i nuke-mask --save
// 参考如下 demo 您可能还需要安装
// tnpm i nuke-view nuke-text nuke-checkbox nuke-button nuke-page --save
  • 调用示例
