this will not happen after changing openKeys and selectedKeys to defaultOpenKeys and defaultSelectedKeys. I need to implement other functions through openKeys and selectedKeys. How to modify it?

Javascript antd react.js
Jul.08,2021

mode= {this.props.collapsed? 'vertical':' inline'} just judge what mode is based on the shrinking state

I also have the same problem. After looking at the source code of Antd Pro, I found that you can judge that when the menu is put away, Menu does not set the openKeys value, so it becomes an uncontrolled component and gives it to antd to deal with. The following screenshot of the antd pro source code, I try in my own project, can solve the problem 

rootSubmenuKeys = ['/Dashboard', '/Form', 'sub3', 'sub5', 'sub6', 'sub7', 'sub8'];

state = {
    collapsed: false,
    openKeys: this.props.location.pathname === '/' ? ['/Dashboard'] : [urlToList(this.props.location.pathname)[0]],
    oldOpenKeys: []
}

componentWillUnmount() {
    this.triggerResizeEvent.cancel();
}

@Debounce(0)
triggerResizeEvent() {
    const event = document.createEvent('HTMLEvents');
    event.initEvent('resize', true, false);
    window.dispatchEvent(event);
}

toggleCollapsed = () => {
    this.setState({
        oldOpenKeys: this.state.openKeys
    });
    if (!this.state.collapsed) {
        this.setState({
            collapsed: !this.state.collapsed,
            openKeys: []
        });
    } else {
        this.setState({
            collapsed: !this.state.collapsed,
            openKeys: this.state.oldOpenKeys
        });
    }
}

onOpenChange = (openKeys) => {
    const latestOpenKey = openKeys.find(key => this.state.openKeys.indexOf(key) === -1);
    if (this.rootSubmenuKeys.indexOf(latestOpenKey) === -1) {
        this.setState({ openKeys });
    } else {
        this.setState({
            openKeys: latestOpenKey ? [latestOpenKey] : [],
        });
    }
  }

changLang() {
    const locale = getLocale();
    if (!locale || locale === 'zh-CN') {
        setLocale('en-US');
    } else {
        setLocale('zh-CN');
    }
}

excuse me, has this problem been solved? I also have this problem, if you have solved it, please let me know, thank you!

Previous: When vuejs switches routes, the memory leaks and IE11 cannot reclaim garbage memory. Open the task manager and switch routes many times. You can see that IE browsers can occupy more than 1 GB of memory.
