![]() ![]() This means that the DOM gets updated with all previous queue items (such as inserted via $.append(.), and when your code runs, the DOM is fully available. This means that setting a timeout of 0 puts it into the UI/DOM-portion of javascript's event queue, to be run at the next possible chance. This will often be a good time to perform tasks that are needed before the user views or interacts with the page, for example to add event handlers and initialize plugins. However, this process can be separated out into a jQuery ‘filtering’ function which does all the grunt work. Usually, this happens by adding classes and selecting only those elements which do not have that class. ![]() What this does is essentially puts the function into the higher queue (the one that handles the UI/DOM), and does not run it before the specified time. ready() method offers a way to run JavaScript code as soon as the page's Document Object Model (DOM) becomes safe to manipulate. Currently, we have to manually ensure that an element is only initialized once. The "larger" scoped queue holds tasks that update the UI (and DOM), while the micro queue performs quick-task type operations.Īlso realize that setting a timeout doesn't guarantee that the code performs exactly at that specified value. Depending on the browser, the load event may not trigger if the image is cached (Firefox and IE). This event works with elements associated with a URL (image, script, frame, iframe), and the window object. The load event occurs when a specified element has been loaded. Now put downloaded jquery-2.1.3.min.js file in a directory of your website, e.g. The load () method attaches an event handler to the load event. as I understand (though my understanding might be a bit shaky), there's two javascript event queues - one for macro events and one for micro events.
