The response from a file download error is generally no different from a normal HTML response, the only difference here is that is has an error message as HTML content.
The browser will now happily replace your existing page and address with the new error message. Not only have we now displayed an ugly error message to the user but we have also caused them to leave whatever page they were on.
Imagine you have created a nearly exclusively Ajax site like Gmail.
A response like this from the server will cause your entire DOM to be replaced by an error message. Imagine this happening to you in Gmail and having to load up everything all over again.
What is the response time of your web site in terms of serving up static files? Is a user going to immediately look in the far corners of their screen for some sort of a spinning indicator or might they get confused or angry based on their technical prowess?
Maybe they are looking at one of these? An average user might expect some sort of indication of what is going on. Unfortunately this is not possible due to one key problem: Initiating file download prompts is one of these limitations.
Well how the heck does that work? The concept is nothing new in fact: An iframe and cookie What?! I have to rely on Web. By dynamically inserting a hidden iframe into the DOM and setting its location to the desired file path we can initiate a file download just like it was occurring in the main application window.
This directly gets us around one of the nasties of file downloads — if an error occurs the user has now been forced off of the page they were on which may contain an Ajax application like Gmail to see an ugly error message.
Like a normal file download in the main window an iframe will never fill with content when a successful file download occurs. It simply contains an empty DOM.
Well how do we detect what is going on if nothing happens when the file download is successful. Well this is where the cookie comes in: The response from the web server will now look something like this:Cascading grid layout library.
Options set in HTML must be valid JSON. Keys need to be quoted, for example "itemSelector".Note the value of data-masonry . An HTML5, jQuery-based widget library for building modern web apps. - telerik/kendo-ui-core. I've recently worked on an exercise that asked to re-create a JQuery like library using ES6 only.
From the points above I was able to create the instantiation logic that makes it possible to call methods on selectors e.g class names. Any code that makes achieving a certain goal easier and which can be reused, like an abstraction, is a candidate to be bundled into a library.
