Switch Statement - Basic JavaScript Fast | Switch Case, Default, Break

The switch statement for JavaScript is suitable for us to decide what to do from a finite number of branches. We usually need to set up the default case for the input that does not belong to any of those branches. We can group the cases to execute the same branch by using the break keyword properly. Finally, we must make sure that the data type for the input to check must be the same as that of the case value.

A Vue 2 Component Collection for Stripe.js

Vue Stripe Elements

Flexible and powerful Vue components for Stripe. It's a glue between Stripe.js and Vue component lifecycle.

• Vue 2 component collection: stable ✅
• Vue 3 version: in development 🚧

Quickstart

1. Install package:

# npm
npm i vue-stripe-elements-plus --save-dev

# yarn
yarn add vue-stripe-elements-plus --dev

2. Add Stripe.js library to the page:

<script src="https://js.stripe.com/v3/"></script>

Alternatively, you can load Stripe library dynamically. Just make sure it's ready before your components mount.

3. Use built-in components

Create card

<template>
  <div class="payment-simple">
    <StripeElements
      :stripe-key="stripeKey"
      :instance-options="instanceOptions"
      :elements-options="elementsOptions"
      #default="{ elements }" // attention: important part!
      ref="elms"
    >
      <StripeElement
        type="card"
        :elements="elements"
        :options="cardOptions"
        ref="card"
      />
    </StripeElements>
    <button @click="pay" type="button">Pay</button>
  </div>
</template>

<script>
import { StripeElements, StripeElement } from 'vue-stripe-elements-plus'

export default {
  name: 'PaymentSimple',

  components: {
    StripeElements,
    StripeElement
  },

  data () {
    return {
      stripeKey: 'pk_test_TYooMQauvdEDq54NiTphI7jx', // test key, don't hardcode
      instanceOptions: {
        // https://stripe.com/docs/js/initializing#init_stripe_js-options
      },
      elementsOptions: {
        // https://stripe.com/docs/js/elements_object/create#stripe_elements-options
      },
      cardOptions: {
        // reactive
        // remember about Vue 2 reactivity limitations when dealing with options
        value: {
          postalCode: ''
        }
        // https://stripe.com/docs/stripe.js#element-options
      }
    }
  },

  methods: {
    pay () {
      // ref in template
      const groupComponent = this.$refs.elms
      const cardComponent = this.$refs.card
      // Get stripe element
      const cardElement = cardComponent.stripeElement

      // Access instance methods, e.g. createToken()
      groupComponent.instance.createToken(cardElement).then(result => {
        // Handle result.error or result.token
      })
    }
  }
}
</script>

4. Get advanced

Create multiple elements

<StripeElements
  :stripe-key="stripeKey"
  :instance-options="instanceOptions"
  :elements-options="elementsOptions"
  #default="{ elements }" // attention: important part!
>
  <StripeElement
    type="cardNumber"
    :elements="elements"
    :options="cardNumberOptions"
  />
  <StripeElement
    type="postalCode"
    :elements="elements"
    :options="postalCodeOptions"
  />
</StripeElements>

5. Go wild

You can even create multiple groups, don't ask me why. It's possible.

<StripeElements
  :stripe-key="stripeKey1"
  :instance-options="instanceOptions1"
  :elements-options="elementsOptions1"
  #default="{ elements }" // attention: important part!
>
  <StripeElement
    :elements="elements"
    :options="cardOptions"
  />
</StripeElements>
<StripeElements
  :stripe-key="stripeKey2"
  :instance-options="instanceOptions2"
  :elements-options="elementsOptions2"
  #default="{ elements }" // attention: important part!
>
  <StripeElement
    type="iban"
    :elements="elements"
    :options="ibanOptions"
  />
</StripeElements>

Styles

No base style included. Main reason: overriding it isn't fun. Style as you wish via element options: see details.

API Reference

StripeElements.vue

Think of it as of individual group of elements. It creates stripe instance and elements object.

import { StripeElements } from 'vue-stripe-elements-plus'

props

// https://stripe.com/docs/js/initializing#init_stripe_js-options
stripeKey: {
  type: String,
  required: true,
},
// https://stripe.com/docs/js/elements_object/create#stripe_elements-options
instanceOptions: {
  type: Object,
  default: () => ({}),
},
// https://stripe.com/docs/stripe.js#element-options
elementsOptions: {
  type: Object,
  default: () => ({}),
},

data

You can access instance and elements by adding ref to StripeElements component.

// data of StripeElements.vue
instance: {},
elements: {},

default scoped slot

Elegant solution for props. Really handy because you can make instance and elements available to all children without adding extra code.

<!-- Isn't it cool? I really like it! -->
<StripeElements #default="{elements, instance}">
  <StripeElement :elements="elements" />
  <CustomComponent :instance="instance" />
</StripeElements>

StripeElement.vue

Universal and type agnostic component. Create any element supported by Stripe.

props

// elements object
// https://stripe.com/docs/js/elements_object/create
elements: {
  type: Object,
  required: true,
},
// type of the element
// https://stripe.com/docs/js/elements_object/create_element?type=card
type: {
  type: String,
  default: () => 'card',
},
// element options
// https://stripe.com/docs/js/elements_object/create_element?type=card#elements_create-options
options: {
  type: [Object, undefined],
},

data

stripeElement
domElement

options

Element options are reactive. Recommendation: don't use v-model on StripeElement, instead pass value via options.

data() {
  return {
    elementOptions: {
      value: {
        postalCode: ''
      }
    }
  }
},

methods: {
  changePostalCode() {
    // will update stripe element automatically
    this.elementOptions.value.postalCode = '12345'
  }
}

events

Following events are emitted on StripeElement

• change
• ready
• focus
• blur
• escape

<StripeElement
  :elements="elements"
  @blur="doSomething"
/>

Helpers

In case you like the manual gearbox. Check stripeElements.js for details.

Introduction With Basic JavaScript

The world’s most misunderstood programming language is JavaScript but JavaScript is now used by an incredible number of high-profile applications. So, it’s an important skill for any web or mobile developer to enrich the deeper knowledge in it.

Unlike most programming languages, the JavaScript language has no concept of input or output. It is designed to run as a scripting language in a host environment, and it is up to the host environment to provide mechanisms for communicating with the outside world.

Its syntax is based on the Java and C languages — many structures from those languages apply to JavaScript as well. JavaScript supports object-oriented programming with object prototypes, instead of classes. JavaScript also supports functional programming — because they are objects, functions may be stored in variables and passed around like any other object.

Let’s start off by looking at the building blocks of any language: the types. JavaScript programs manipulate values, and those values all belong to a type. JavaScript’s types are:

· Number

· String

· Boolean

· Function

· Object

· Symbol

and undefined and null, which are … slightly odd. And Array, which is a special kind of object. Date and RegExp, which are objects that you get for free. And to be technically accurate, functions are just a special type of object. So the type of diagram looks like this:

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
</script>

How to comment JavaScript code?

• For single line comment in JavaScript we have to use // (double slashes)
• For multiple line comments we have to use / * – – * /

<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

</script>
