Javascript conditional9/4/2023 ![]() ![]() We are assuming that this list of products is now displayed on our website. We then stored that array as a variable and used a forEach loop to iterate over the list. In the example we set up in the previous articles, we took a bunch of products (mushrooms, steak, fish, aubergines, and lentils) and organised them inside an array. Take a look at Lola Market, which is where I work, for an example of what this would look like. That's a real-world application of the things we want to talk about here. ![]() Let’s imagine that we are working on an online platform that allows us to do our grocery shopping from a website. I've covered those in two previous articles: The only prerequisite is a basic understanding of arrays and loops. ![]() Feel free to follow along while reading through this article. With the help of a beginner-friendly practical example, you'll see how you can use conditionals to process data in different ways and why they're a fundamental tool in development. In this article, I'll explain why we need conditionals and how we can use them as front-end developers. One thing was always particularly hard – to be able to go beyond the syntax of a new concept and place it in a context that made sense.Ĭonditionals are a little more intuitive than other concepts, but I want to show you the big picture. ![]() I came into development from a non-traditional path. And why you will end up using them regularly. It covers why we need them, and how they fit into the front-end context. The removal of the following code is because it is duplicate of $(document).This article is a beginner's introduction to JavaScript conditionals. This let's you show the user anything like Screwdriver instead of Product 1. text() you will be getting the option's value. Var selected = $("#product option:selected").val() īy using. So for example 1 should be called Product 1, 2 should be called Product 2, and so forth. The problem i'm having is that in the options (1/2/3/4/5/6/7) these need to be product names, but it doesnt work without the numbers in there.
