Question

react native怎么调用有参数的函数

Answer 1

// Global.js
var Global = {};
module.exports = Global;
// 调用的页面
let Global = require('./Global');
Global.userToken = 'token';

Answer 2

例如点击按钮就新增一个子组件，同时需要使用ref引用子组件，我像下面这样把ref写在handleClick里面时，因为不在render里面，会报错:addComponentAsRefTo(...): Only a ReactOwner can have refs.
var Father = React.createClass({
getInitalState:function(){
return {children:[]}
},
handleClick:function(){
var childrenTemp = this.state.children
this.setState{children:childrenTemp.push(<Child ref="childRef">)}
},

render:function(){
return (
<div>{this.state.children}</div>
)
}
})
