How do I add a JQuery locators to Selenium Remote Control

Question

I\'ve been using XPath with Selenium quite happily and even using getEval with a but of Javascript, but a colleague said wouldn\'t it be great to be able to use JQuery selec

Answer 1

You can read and execute_script to enable jQuery:

• First you can read the jquery from a jquery.js or jquery.min.js file.
• Then using execute_script(jquery) to enable jquery dynamically.
• Now you can interact with jquery.

here is some code in python, other language would be similar:

browser = webdriver.Firefox() # Get local session of firefox

with open('jquery.min.js', 'r') as jquery_js: #read the jquery from a file
    jquery = jquery_js.read()
    browser.execute_script(jquery)  #active the jquery lib

#now you can write some jquery code then execute_script them
js = """
    var str = "div#myPager table a:[href=\\"javascript:__doPostBack('myPager','%s')\\"]"
    console.log(str)
    var $next_anchor = $(str);
    if ($next_anchor.length) {
        return $next_anchor.get(0).click(); //do click and redirect
    } else {
        return false;
    }""" % str(25) 

success = browser.execute_script(js)
if success == False:
    break

PS: When I use Selenium to fetch some content from some website, they always ban me. Now you should use some proxy to go over it.
here is some code:

PROXY_HOST = "127.0.0.1"
PROXY_PORT = 8087
SOCKS_PORT = 8088

fp = webdriver.FirefoxProfile()

# Direct = 0, Manual = 1, PAC = 2, AUTODETECT = 4, SYSTEM = 5
fp.set_preference("network.proxy.type", 1)

fp.set_preference("network.proxy.http", PROXY_HOST)
fp.set_preference("network.proxy.http_port", PROXY_PORT)
fp.set_preference("network.proxy.socks", PROXY_HOST)
fp.set_preference("network.proxy.socks_port", SOCKS_PORT)
fp.set_preference("network.proxy.ftp", PROXY_HOST)
fp.set_preference("network.proxy.ftp_port", PROXY_PORT)
fp.set_preference("network.proxy.ssl", PROXY_HOST)
fp.set_preference("network.proxy.ssl_port", PROXY_PORT)

fp.set_preference("network.proxy.no_proxies_on", "") # set this value as desired

browser= webdriver.Firefox(firefox_profile=fp) # with proxy
browser = webdriver.Firefox() # no proxy
browser.get("http://search.example.com") # Load page

elem = browser.find_element_by_id("query_box") # Find the query input
elem.send_keys(u'my query string') # send query string to the input
elem.submit() # submit the query form
