json服务器
数据的代码。并在屏幕上呈现七个名称。我想按输入过滤,只渲染元素filtereds
My Apps.js:
class AppRouter extends React.Component {
state = {
employeeCurrent: [],
employee: []
};
componentDidMount() {
axios
.get("http://127.0.0.1:3004/employee")
我试图将状态传递给应用程序。但是没有成功。我尝试了身体里的一切。但是也没有成功。有人能帮我怎么做吗
我在打电话,所以有些东西不好记。对不起
试试这个
class Body extends React.Component {
getName = () => {
const { employee, add } = this.props;
//Filter names in employee array with input
const filterNames = employee.filter(x => x.name === "check with the input value" );
// Then map over the filtered names
return filterNames.map(name => (
<Link className="link" to={`/user/${name.name}`}>
{" "}
<div onClick={() => add(name)} key={name.id} className="item">
{" "}
<img
className="img"
src={`https://picsum.photos/${name.name}`}
/>{" "}
<h1 className="name"> {name.name} </h1>
</div>{" "}
</Link>
));
};
render() {
return <div className="body">{this.getName()}</div>;
}
}
类主体扩展了React.Component{
getName=()=>{
const{employee,add}=this.props;
//使用输入筛选员工数组中的姓名
const filterNames=employee.filter(x=>x.name==“检查输入值”);
//然后映射过滤后的名称
返回filterNames.map(名称=>(
{" "}
add(name)}key={name.id}className=“item”>
{" "}
{" "}
{name.name}
{" "}
));
};
render(){
返回{this.getName()};
}
}
这里的过滤发生在哪里?如果我没有弄错,你想根据输入对名称进行过滤吗?@AbidHasan这段代码没有be@MontyGoldy是的,他们是..伙计,你可以使用“过滤器”高阶函数来得到结果。例如:-const filteredNames=this.state.employee.filter(x=>x.name==(检查输入值))
class Body extends React.Component {
getName = () => {
const { employee, add } = this.props;
return employee.map(name => (
<Link className="link" to={`/user/${name.name}`}>
{" "}
<div onClick={() => add(name)} key={name.id} className="item">
{" "}
<img
className="img"
src={`https://picsum.photos/${name.name}`}
/>{" "}
<h1 className="name"> {name.name} </h1>
</div>{" "}
</Link>
));
};
render() {
return <div className="body">{this.getName()}</div>;
}
}
class Body extends React.Component {
getName = () => {
const { employee, add } = this.props;
//Filter names in employee array with input
const filterNames = employee.filter(x => x.name === "check with the input value" );
// Then map over the filtered names
return filterNames.map(name => (
<Link className="link" to={`/user/${name.name}`}>
{" "}
<div onClick={() => add(name)} key={name.id} className="item">
{" "}
<img
className="img"
src={`https://picsum.photos/${name.name}`}
/>{" "}
<h1 className="name"> {name.name} </h1>
</div>{" "}
</Link>
));
};
render() {
return <div className="body">{this.getName()}</div>;
}
}
