我正在尝试渲染反应组件。组件的第一部分将保持不变,但第二部分需要根据从props返回的数据动态更改。有没有办法将这些连接在一起?
import * as Icon from 'react-cryptocoins';
class ResultRow extends PureComponent {
render() {
return (
<div className="component-result-row">
<Icon.{this.props.name}/>
</div>
);}}
硬编码名称按预期工作
<{Icon.image1}/>
解决方案:
import * as Icon from 'react-cryptocoins';
class ResultRow extends PureComponent {
var name = this.props.name;
var Component = Icon[symbol];
render() {
return (
<div className="component-result-row">
<Component/>
</div>
);}}

一种可能的方法是将值存储在变量中(应以大写字母开头)然后渲染它。
像这样:
mDrawerLayoutLeft.addDrawerListener(new DrawerLayout.DrawerListener() {
@Override
public void onDrawerOpened(View drawerView) {
//lock the right side drawer when open the left drawer
mDrawerLayoutRight.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
}
@Override
public void onDrawerClosed(View drawerView) {
//unlock the right side drawer when close the left drawer
mDrawerLayoutRight.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
}
});
