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 avoid […]
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” }); } […]
There are many reasons for manipulating variables in JMeter, especially when you are loading data from a CSV data set config element.

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. There […]
If you have been writing websites or web apps for any length of time, you will almost certainly have implemented some form of lazy-loading using JavaScript. I recently worked on a web app that implemented a search that benefitted to the tune of half-a-gig by deferring the loading of images until those images were actually […]
This is the JavaScript edition, but I also have a C# method to remove special characters diacritic marks. I was working on a search system that needed to simplify the strings for comparison. It needed to compare the text regardless of special characters (diacritic marks) or casing. The following function breaks the special characters into […]
One of the most common issues I see in content-managed websites is the presence of a fully-qualified image address that isn’t secure when the website itself is. When this happens, you’ll need to find all images that aren’t secure and fix them. For example, if you are visiting https://www.example.com and there is an image http://www.example.com/image.png […]
Has you ASP.NET applicaiton reported that minification failed? If you are using bundles in application, you might come across this exception comment at the top of your larger-than-expected bundle file. /* Minification failed. Returning unminified contents.

There are a great many posts on the subject of capturing events for telephone or email clicks in Google Analytics. Of the examples I found, none handled asynchronous content.
