Implementation Reference
- src/tools/actionTools.ts:438-456 (registration)Registration of the 'browser_focus_element' tool, including inline handler function that creates ActionService and calls focusElement
server.tool('browser_focus_element', 'Focus on a specific element', { ...locatorSchema }, async ({ by, value }) => { try { const driver = stateManager.getDriver(); const actionService = new ActionService(driver); await actionService.focusElement({ by, value }); return { content: [{ type: 'text', text: `Focused on element` }], }; } catch (e) { return { content: [ { type: 'text', text: `Error focusing on element: ${(e as Error).message}`, }, ], }; } }); - src/tools/actionTools.ts:438-456 (handler)Inline handler function for the tool, which handles execution, error catching, and response formatting
server.tool('browser_focus_element', 'Focus on a specific element', { ...locatorSchema }, async ({ by, value }) => { try { const driver = stateManager.getDriver(); const actionService = new ActionService(driver); await actionService.focusElement({ by, value }); return { content: [{ type: 'text', text: `Focused on element` }], }; } catch (e) { return { content: [ { type: 'text', text: `Error focusing on element: ${(e as Error).message}`, }, ], }; } }); - src/types/index.ts:29-35 (schema)Zod schema for locator parameters used in the tool's input schema
export const locatorSchema = { by: z .enum(['id', 'css', 'xpath', 'name', 'tag', 'class', 'link', 'partialLink']) .describe('Locator strategy to find element'), value: z.string().describe('Value for the locator strategy'), timeout: z.number().optional().describe('Maximum time to wait for element in milliseconds'), }; - src/services/actionService.ts:97-101 (helper)Core implementation of focusing an element using Selenium WebDriver's executeScript to call focus() on the located element
async focusElement(params: LocatorParams): Promise<void> { const locator = LocatorFactory.createLocator(params.by, params.value); const element = await this.driver.wait(until.elementLocated(locator), params.timeout || 15000); await this.driver.executeScript('arguments[0].focus();', element); }
