### Jquery Mobile Form - Flip toggle switch control

A binary flip switch is a very common UI element in the mobile web world and was made popular by our very own iOS. This flip switch is used mostly for binary on/off or true/false data inputs. To create a flip switch or a toggle switch, start with a select with data-attribute="slider" and two options. Jquery Mobile would style this select as a regular flip switch with capsule corners and a a circular handle which can be either dragged from one end to the other or tap either sides of the switch.

The flip toggle switch is available in 2 flavors/sizes - regular and mini. Adding a data attribute data-mini="true" to the input tag renders a smaller sized flip switch. Let's take a look at the code sample below to understand the working in a better way.

In the code above, you will see 4 different implementations of the flip switch. The first one is a regular flip switch with the label and the toggle button one below the other. The second implementation is exactly similar to the first implementation with the only difference of the added data attribute "data-mini="true"" which reduces the size (basically height) of the flip switch.

The third implementation gets the label and the slider on the same line. This implementation is done using a div with data attribute data-role="fieldcontain" around the label and select tags. This div has to be within a form tag. Maintaining the HTML structure is very important when using JQuery Mobile framework. T
o disable the input field just add the keyword "disabled" to the input tag and your input type would be disabled.

Since this flip switch is nothing but a select with two options, we can make either one of the options selected by default by just writing "selected" for that particular option in the select. This can be seen in the code above, where the last last flip switch is disabled and is "ON"

For the sake of accessibility, jQuery Mobile requires that all form elements be paired with a meaningful label. To hide labels in a way that leaves them visible to assistive technologies. — for example, when letting an element's placeholder attribute serve as a label — apply the helper class ui-hidden-accessible to the label itself. While the label will no longer be visible, it will be available to assisitive technologies such as screen readers.

Hope this post has been informative to you and helps you use the range input type effectively to create the range slider in your next Jquery Mobile based application.

### ES6 101 - Lexical Declarations - Const

ES6 101 - Lexical Declarations - Const

This is the third post in the ES6 101 Series and we will be looking at the ES6 lexical declartions keyword const. This is more of a continuation of the post on let, so I would highly recommend you to read that before you move forward. In case you feel like looking at const that too works! Go ahead and keep reading.As we saw in the post yesterday, variables created with the let keyword have limited scope and they live within the block, statement or the expression that they have been declared in. You cannot redeclare the let variables but these variables are mutable, i.e. theirs values can be changed and updated.As the name suggests, const helps you create variables that have a constant value! These variables are not mutable, which means, the value of these variables cannot be changed or updated. Let’s look at a few examples to understand this better.Examples using ES6 constconst pi = 3.14; console.log(pi); pi = ++pi; // Uncaught TypeEr…

### ES6 Fat Arrow Functions

ES6 101 - Fat Arrow Functions

I attended a 2 day ReactJs 101 Training last week. Yes! towards the end of 2017 - React 101. That story is for another blog post, but I am happy I took this training. It opened my eyes to a lot of things that I have not been working on and made me realize that I was really falling behind the Javascript scene.

The main thing that I realized I was lacking was ES6. I know a couple of things, but am not using it on a regular basis. One statement by the trainer, especially hit me hard.

"ES6 has been around for over 2 years now (with babel). There is no reason for you to not use it! If you are not using it today, you are definitely missing the boat!"

So have now decided to start learning something everyday and post it. Share my learnings with the world and get some feedback, if anyone is willing to share some.

I am going to start with the Arrow Functions or as they are very commonly referred to as Fat Arrow Functions. Whenever someone refers to a Fat A…

### ES6 101 - Lexical Declarations Let

ES6 Lexical Declarations - Let
This is the second post in the ES6 series and we will be covering a lexical declaration - ‘Let’ today. Before this we have looked into the ES6 Fat Arrow Functions. We looked at the syntax changes from ES5 to ES6, how return is implicit and how this works with the new Arrow syntax.Let’s now look at what let is. Simply put, let is the new var. Then what is the difference you ask! well, let’s look at right now. Whenever you see let in your code base, you should now consider the following thing.The scope of the variable declared with the let keyword is limited to the block, statement or expression that it is being used in. This differs from the var keyword, which defines variables globally or local to a function regardless of block scope.Let’s take a look at a few examples to see how var and let differ from each other.Examples using ES6 letlet does not attach anything to window 😍var a = 10; let b = 20; console.log(window.a); // 10console.log(window.b…
