方式一：内联调用法
import React, { Component }from 'react';
class funcextends Component{
constructor(porps){
super(props);
}
funcOne(){
console.log('内联调用法')
}
render(){
return (
)
}
}
方式二：配置中调用法
import React, { Component }from 'react';
class funcextends Component{
constructor(porps){
super(props);
this.funcTwo =this.funcTwo.bind(this)
}
funcTwo(){
console.log('配置中调用法')
}
render(){
return (
)
}
}
方式三：箭头函数调用法（最推荐）import React, { Component }from 'react';
class funcextends Component{
constructor(porps){
super(props);
}
funcThree:() => {
console.log('箭头函数调用法')
}
render(){
return (
)
}
}
