public class JQuerySelector extends By {

    private final String jQuerySelector;

    public JQuerySelector(String selector) {
        this(selector, true);
    }

    public JQuerySelector(String selector, boolean visible) {
        this.jQuerySelector = selector + (visible ? ":visible" : "");
    }

    @Override
    public List<WebElement> findElements(SearchContext context) {
        return (List<WebElement>) findWithJQuery(context, true);
    }

    @Override

        return (WebElement) findWithJQuery(context, false);
    }

    private Object findWithJQuery(SearchContext context, boolean returnList) {
        String getArgument = returnList ? "" : "0";

        if (context instanceof RemoteWebElement) {
            WebDriver driver = ((RemoteWebElement) context).getWrappedDriver();

            return ((JavascriptExecutor) driver).executeScript("return $(arguments[0]).find('" + escape(jQuerySelector) + "').get(" + getArgument + ");", context);
        }

        return ((JavascriptExecutor) context).executeScript("return $('" + escape(jQuerySelector) + "').get(" + getArgument + ");");
    }

    @Override
    public String toString() {
        return "By.jQuerySelector: " + jQuerySelector;
    }
    
    private String escape(String s) {
        return s.replace("'", "\\'");
    }
}

For front-end tests, it is reasonable to work with elements which are visible to user, by default.

I like the visibility addition, changed it in our own codebase!

What would happen if Jquery is not included in the Application.

if jquery is not included with the application you have to inject it somehow.

one method also in java. I just used this and it works. There is also apparently a method to have selenium inject it as a user extension.

Please write an example code for how this class can be used.
thanks
