      • register

        public void register​(java.lang.String name,
                     java.lang.String script,
                     Selectors.RegisterOptions options)
        Description copied from interface: Selectors
        Selectors must be registered before creating the page.

        **Usage**

        An example of registering selector engine that queries elements based on a tag name: 

        
 // Script that evaluates to a selector engine instance. The script is evaluated in the page context.
 String createTagNameEngine = "{\n" +
   "  // Returns the first element matching given selector in the root's subtree.\n" +
   "  query(root, selector) {\n" +
   "    return root.querySelector(selector);\n" +
   "  },\n" +
   "  // Returns all elements matching given selector in the root's subtree.\n" +
   "  queryAll(root, selector) {\n" +
   "    return Array.from(root.querySelectorAll(selector));\n" +
   "  }\n" +
   "}";
 // Register the engine. Selectors will be prefixed with "tag=".
 playwright.selectors().register("tag", createTagNameEngine);
 Browser browser = playwright.firefox().launch();
 Page page = browser.newPage();
 page.setContent("<div><button>Click me</button></div>");
 // Use the selector prefixed with its name.
 Locator button = page.locator("tag=button");
 // Combine it with built-in locators.
 page.locator("tag=div").getByText("Click me").click();
 // Can use it in any methods supporting selectors.
 int buttonCount = (int) page.locator("tag=button").count();
 browser.close();
        Specified by:
        register in interface Selectors
        Parameters:
        name - Name that is used in selectors as a prefix, e.g. {name: 'foo'} enables foo=myselectorbody selectors. May only contain [a-zA-Z0-9_] characters.
        script - Script that evaluates to a selector engine instance. The script is evaluated in the page context.
