Selecting and Identifying element with JQuery to use it in Selenium 2 Java API

Question

This is the situation:

• I use the Java API of Selenium 2 to open and control a firefox browser instance
• I load the jQuery script to a page via JavaScri

Answer 1

Using eval makes it even easier. Use an index selector such as [0] with the jQuery code or it will return a collection of elements.

    String elementLocator = "$('#btnID')[0]";
    public RemoteWebElement getElementByJQueryLocator(String jQueryLocator){
        JavascriptExecutor js = (JavascriptExecutor) driver;
        RemoteWebElement element = (RemoteWebElement) js.executeScript("return eval(arguments[0]);", jQueryLocator);
        return element;
    }

        RemoteWebElement webElement = getElementByJQueryLocator(elementLocator);
        webElement.click();

Answer 2

Not sure of your exact problem but you can build you locator using html id, name, class etc attributes.

Answer 3

I found the solution, which is quite easy:

String jQuerySelector = "'#myDiv input.test'";
RenderedWebElement webElement = (RenderedWebElement) ((JavascriptExecutor) webDriver).executeScript("return $(" + jQuerySelector+ ").get(0);");

Working with an element in jQuery which was previosly selected in Selenium works too:

String jQuerySelector = "arguments[0]";
((JavascriptExecutor) webDriver).executeScript("return $(" + jQuerySelector+ ").doSomethingInJquery();", webElement);
