As my grandma used to say, “there’s only one thing worse than a scroll-linked positioning effect and that’s not being able to scroll at all”.

This is a little funky script to intercept AJAX requests and raise a simple custom event for everything else in your app to listen to. To use this, you just need to listen for a custom event named `AjaxDetected`. The method, url, and any data is passed in the event detail. document.body.addEventListener(‘AjaxDetected’, function (e) {Continue reading “AJAX Request Interceptor”

Although it has been abused with an enthusiasm that borders on the insane, there are good reasons to use the Notifications API in your web apps.

Avoid Expensive innerHTML Manipulation with insertAdjacentHTML
It is pretty well known these days that fiddling with innerHTML is terribly inefficient. It triggers serialization, and it can result in invalid markup. Nevertheless, you’ll still find this being done in many applications. elem.innerHTML = elem.innerHTML + ‘<a href=”https://www.example.com”>Visit Example Dot Com</a>’; // or elem.innerHTML += ‘<a href=”https://www.example.com”>Visit Example Dot Com</a>’; You can avoidContinue reading “Avoid Expensive innerHTML Manipulation with insertAdjacentHTML”
Set a Minimum Font Size
This is just a little script I needed to use to increase text size conditionally. It only increases text below a minimum size and leaves everything else. (function () { var minFontSize = function () { $(“.content-zone *”).each(function () { var $this = $(this); if (parseInt($this.css(“fontSize”), 10) < 16) { $this.css({ “font-size”: “16px” }); }Continue reading “Set a Minimum Font Size”

Fixing CSS object-fit for Internet Explorer
A common problem with images, especially if they are user-generated, is that they don’t have the correct aspect ratio for their intended purpose. Also, as we re-flow pages for many different devices, we often want the image to work with different aspect ratios. This is where the CSS object-fit property comes in very useful. ThereContinue reading “Fixing CSS object-fit for Internet Explorer”
