Selenium wait for Ajax content to load - universal approach

Question

Is there a universal approach for Selenium to wait till all ajax content has loaded? (not tied to a specific website - so it works for every ajax website)

Answer 1

I have been using this simple do while to iterate until an AJAX is finished. It consistently works for me.

public void waitForAjax() throws InterruptedException{
    while (true)
    {
        Boolean ajaxIsComplete = (Boolean) ((JavascriptExecutor)driver).executeScript("return jQuery.active == 0");
        if (ajaxIsComplete){
            info("Ajax Call completed. ");
            break;
        }
        Thread.sleep(150);
    }
}
