Update base page

Once again, we have to mofidy "base_page.rb" again as following:

# encoding: utf-8

class Page
def initialize(driver)
    @driver = driver
end

def searchByKeyword (keyword)
    searchKeyword=findElementBy("id","twotabsearchtextbox")
    searchKeyword.clear
    searchKeyword.send_keys keyword
    clickElementBy("class", "nav-submit-input")
end

def getCurrentItemTitle
    $bookTitle=findElementBy("id", "productTitle").text
end

def openShoppingCart
    clickElementBy("id","nav-cart")
end

def clickElementBy (type, value)
    findElementBy(type, value).click
end

def inputToElementWith (type, value, input)
    inputElement=findElementBy(type, value)
    inputElement.clear
    inputElement.send_keys input
end

def findElementBy (type, value)
    if type=="class"
        @element=@driver.find_element :class => value
    elsif type=="css"
        @element=@driver.find_element :css => value
    elsif type=="id"
        @element=@driver.find_element :id => value
    elsif type=="link"
        @element=@driver.find_element :link => value
    elsif type=="name"
        @element=@driver.find_element :name => value
    elsif type=="partial_link"
        @element=@driver.find_element :partial_link_text => value
    elsif type=="tag"
        @element=@driver.find_element :tag_name => value
    elsif type=="xpath"
        @element=@driver.find_element :xpath => value
    else
        p "incorrect selector type"
    end
end

def waitForJsOrAjax
    sleep (10) #it's better to wait for js or AJAX executed complete, but there is not a general way we can follow in industrys
end
end
