Selenium only allows you to get notified of URL changes that were initiated by Selenium itself (not very helpful) or poll driver.current_url (doesn’t work). This works nicely, but what if you want to get data back? For example, I want to know which URLs were requested at the top level - in particular, whether there was a redirect before the final URL. Refactor code so all content/DOM access is grouped in a single object or file. ndMouseEvent("mouseup", rect.left + 1, rect.top + 1, 1, 1, 0) gBrowser. Here is a technique for writing an add-on that works in both Electrolysis and non-Electrolysis browsers (e.g. ndMouseEvent("mousedown", rect.left + 1, rect.top + 1, 1, 1, 0) QueryInterface(Ci.nsIInterfaceRequestor) Var event = document.createEvent("Events") Įvent.initEvent("testhelper_middleclick", true, false) Īnd the extension listens to that event: ("testhelper_middleclick", function(event) So if a test wants the element to be middle-clicked it can trigger a custom event: driver.execute_script(''' And WebDriver.execute_script isn’t any help here either, it won’t let you run privileged code.Īfter briefly considering using send_keys functionality to open Web Console on about:config and typing code into it (yes, it looks like that would actually work), I decided to go with a less crazy solution: install an additional extension to implement the necessary functionality. This tutorial shows you how you can implement addEventListener() in your code. So WebDriver will only let you work with the currently selected tab, inactive tabs are off limits. The JavaScript addEventListener() method allows you to set up functions to be called when a specified event happens, such as when a user clicks a button. The ability to pass elements as parameters to WebDriver.execute_script is very useful, so it is surprising that it doesn’t seem to be documented properly anywhere.īut what about working with tabs or middle-clicking links? It seems that tabbed browsing wasn’t invented yet back when that API was designed, so it only has a concept of windows - not very useful. That issue turned out to be solved fairly easily: driver.execute_script("arguments.focus()", element) Clicking isn’t always an option, since it might trigger a link for example. One issue: there is no way to focus an element without clicking it. However, the functionality seems to be geared towards very old browsers (think IE6) and some features are nowhere to be found. All in all, writing the tests is fairly simple once you get used to the rather arcane API. So I decided looking into Selenium WebDriver in order to write integration tests that would automate Firefox. Enable JavaScript to view data.My Google search link fix extension had a bunch of regressions lately and I realized that testing its impact on the search pages manually isn’t working - these pages are more complicated than it looks like, and there are lots of configuration options affecting them. Especificaciones SpecificationĭOM Standard # ref-for-dom-eventtarget-addeventlistener③īCD tables only load in the browser with JavaScript enabled. links: PTS, VCS area: main in suites: wheezy size: 1,013,096 kB sloc: cpp: 3,984,020 ansic: 1,866,720 java: 219,720 python: 213,675. Moreover, in the first case, since no reference to the anonymous functions is kept, it is not possible to call element.removeEventListener because we do not have a reference to the handler, while in the second case, it's possible to do myElement.removeEventListener("click", processEvent, false). This results in smaller memory consumption. In the second case, the same previously declared function is used as an event handler. gBrowser.addEventListener (DOMContentLoaded, thefunctionname, true) This is a very reliable way of knowing when the browser has loaded only the page. It also shows you how to attach event listeners to injected elements and elements that were already in the webpage. When a page matching a certain host name is found it will inject into it. () ofrece un objeto (que puede ser convertido en cadena con toString () ). ff-addon-template-BootstrapWatchHostEventListener - Uses event listener (DOMContentLoaded) to watch page loads in all tabs and windows with gBrowser. In the first case, a new (anonymous) function is created at each loop turn. Para corregir esto en forma sencilla, emplea gBrowser.addEventListener ('load', myFunc, true), según se describe aquí.
