Jquery Mobile Form - Select Menus Part II

    In part II of this tutorial on creating select menus using Jquery Mobile, we will discuss some customization techniques like overriding the default native OS select menu or disabling an option or creating a multi-select select box. It is advisable that you take a look at part I of this tutorial where we have discussed the basics of the select menu. In case you have decided to proceed with this part, then we are ready to take a look at the code that follows.



    In the example code above, you will observe 2 different selects. We will be discussing the following data attributes and HTML5 properties that will enhance the select menus further.

1. data-native-menu="false"
2. data-placeholder="true"
3. disabled
4. multiple

    As seen in the first implementation, by adding the data attribute data-native-menu="false" we can simply override the native OS menu control and display a pop-up containing the options in a listview. If there are a large number of options, the framework will automatically create a new "page" populated with a standard listview for the options.

    To create a placeholder for the select we just need to include a data attribute data-placeholder="true" to an option which holds the placeholder text. This option will then be styled accordingly and will not be selectable. In case you want to disable an option just add disable to that option and that option will be styled as a disabled listview. All the above three things are part of the first implementation in the above example.

    Lets now take a look at how to create a multi select select box. It is as simple as it sounds a big task. Just add keyword multiple to your select element (as seen in the second implementation) and the framework will style each of your option as a listview with a checkbox and you can select multiple options. Each of the options selected will be populated as comma seperated list on the custom select button. To top this off Jquery Mobile framework will aslo add a count bubble on the select button indicating how many options are selected.

    Hope you have enjoyed this post and the other form elements tutorials. Drop a line in case this has helped you, or if you have any concerns, comments on the post or the series of examples that I have shared so far. You can also check out the comprehensive list of examples on Jquery Mobile listview. Till next time, keep sharing - Sharing is Caring.

ES6 101 - Spread operator

ES6 101 - Spread Operator
Welcome to the fourth post in the ES6 101 series and the topic of discussion today is the Spread operator or the dot dot dot operator.... It is not very common to call it the “dot dot dot” operator, but I just kind of like the ring to it! Also when you say “dot dot dot” it actually helps me visualize unpacking multiple gifts from a gift box. Wondering why I am taking about gifts and gift boxes and “dot dot dot”. Well, the spread operator... is actually more like unwrapping gifts from a gift box. The spread syntax allows an iterable such as an array expression to be expanded in-place. Let’s actually dive into some examples straight away. It is much more simpler that way!Examples of the ES6 Spread Operator ...Example #1Problem statement: Let’s write a function to display the sum of 3 numbers passed to it in an array.

We would have done this as follows in the old ES5 way. 😏var arr = [1,2,3]; functionsum(a,b,c) { var output = a + b + c; consol…

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…
