Now, when you browse to any page and select your Extension icon, the pop-up menu is displayed as follows: Add functionality to remove the displayed image when selected.The third script line adds a click event that covers the entire image allowing the user to select anywhere on the image and that image is removed from the page (along with it is event listener). ![]() The second script line dynamically inserts into the DOM header a section that you must assign as a slide-image class to your img element. The first script line appends an img element right below the body of your browser tab that has the slide-image class assigned as well as the imageDivId as the ID of that image element. That function simply processes the three jQuery script lines. The first parameter of that function is an object that has attributes as assigned by sendMessage. When an event is processed by the listener, the function that is the first parameter is run. Remember, from popup.js, when you used the sendMessage method, those attributes of the first parameter are url and imageDivId. The first parameter of the addListener method is a function whose first parameter, request, is the details of the message being passed in. This listener waits for messages like the one you sent from the popup.js described earlier with the Extension API method. Notice that all the above JavaScript does is to register a listener using the Extension API method. You also pass in the current tab ID, which is used later in this article:Ĭonst sendMessageId = document.getElementById("sendmessageid") Ĭ() The following code outlines the updated code in popup/popup.js.
