问题描述
假设我有一个包含这样的渲染的组件:
Say I have a component with a render like this:
<View style={jewelStyle}></View>其中jewelStyle =
Where jewelStyle =
{ borderRadius: 10, backgroundColor: '#FFEFCC', width: 20, height: 20, },如何使背景颜色动态和随机分配?我尝试过
How could I make the background colour dynamic and randomly assigned? I've tried
{ borderRadius: 10, backgroundColor: getRandomColor(), width: 20, height: 20, },
任何提示?
推荐答案我通常会做以下行:
<View style={jewelStyle()} />...
jewelStyle = function(options) { return { borderRadius: 10, background: randomColor(), } }每次渲染视图时,将使用与其关联的随机颜色来实例化新的样式对象。当然,这意味着颜色将在每次组件被重新渲染时改变,这可能不是你想要的。您可以这样做:
Every time View is rendered, a new style object will be instantiated with a random color associated with it. Of course, this means that the colors will change every time the component is re-rendered, which is perhaps not what you want. Instead, you could do something like this:
var myColor = randomColor() <View style={jewelStyle(myColor)} />...
jewelStyle = function(myColor) { return { borderRadius: 10, background: myColor, } }更多推荐
