Input元素中的类可以引用html中的标签吗？

Question

    let win, menu;

    function createWindow() {
        const electronScreen = screen;
        const size = electronScreen.getPrimaryDisplay().workAreaSize;

        win = new BrowserWindow({
            x: 0,
            y: 0,
            width: size.width,
            height: size.height
        });

        // and load the index.html of the app.
        win.loadURL('file://' + __dirname + '/index.html');
        win.webContents.openDevTools();

        win.on('closed', () => {
            win = null;
        });
    }

    function createMenu() {
        const template = [{
                label: 'Edit',
                submenu: [
                    { role: 'undo' },
                    { role: 'redo' },
                    { type: 'separator' },
                    { role: 'cut' },
                    { role: 'copy' },
                    { role: 'paste' },
                    { role: 'pasteandmatchstyle' },
                    { role: 'delete' },
                    { role: 'selectall' }
                ]
            },
            {
                label: 'View',
                submenu: [
                    { role: 'reload' },
                    { role: 'forcereload' },
                    { role: 'toggledevtools' },
                    { type: 'separator' },
                    { role: 'resetzoom' },
                    { role: 'zoomin' },
                    { role: 'zoomout' },
                    { type: 'separator' },
                    { role: 'togglefullscreen' }
                ]
            },
            { role: 'window', submenu: [{ role: 'minimize' }, { role: 'close' }] },
            {
                role: 'help',
                submenu: [{
                    label: 'Learn More',
                    click() {
                        require('electron').shell.openExternal('https://electron.atom.io');
                    }
                }]
            }
        ];

        menu = Menu.buildFromTemplate(template);
        Menu.setApplicationMenu(menu);
    }

    try {
        app.on('ready', function() {
            createWindow();
            createMenu();
        });

        app.on('window-all-closed', () => {
            if (process.platform !== 'darwin') {
                app.quit();
            }
        });

        app.on('activate', () => {
            if (win === null) {
                createWindow();
            }
        });
    } catch (e) {
        throw e;
    }

是否可以将 for =“file_upload”分配给输入中的 class =“file_upload”类而不是 id =“file_upload”

当我尝试它不适合上课但它适用于ID。我可以知道我是否必须使用一些不同的方法来使用类？
