反应中循环的建议

Question

有一个对象数组。我想把它放在一个循环中，以查找checked是true还是false ..如果它是true，那么我想用每个数组的值连接。请提出任何建议

plugin:[ 
{checked :true,value:'link', name:'link', id:'linkId'}, 
 {checked  :true,value:'plug', name:'plug', id:'plugId'}, 
 {checked :true, value:'switch', name:'switch', id:'switchId'}, 
]

你走了：

const plugin = [ 
    {checked :true,value:'link', name:'link', id:'linkId'}, 
    {checked  :true,value:'plug', name:'plug', id:'plugId'}, 
    {checked :true, value:'switch', name:'switch', id:'switchId'}, 
];

render() {
    return (
        <div> 
        { plugin.map(el => {
            return el.checked ? el.value : null ;
        }) } 
        </div>
    ) 
}
