Default Params in Javascript

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.

Focal Transformer | Official Implementation of Focal Transformer

Focal Transformer

This is the official implementation of our Focal Transformer -- "Focal Self-attention for Local-Global Interactions in Vision Transformers", by Jianwei Yang, Chunyuan Li, Pengchuan Zhang, Xiyang Dai, Bin Xiao, Lu Yuan and Jianfeng Gao.

Introduction

Our Focal Transfomer introduced a new self-attention mechanism called focal self-attention for vision transformers. In this new mechanism, each token attends the closest surrounding tokens at fine granularity but the tokens far away at coarse granularity, and thus can capture both short- and long-range visual dependencies efficiently and effectively.

With our Focal Transformers, we achieved superior performance over the state-of-the-art vision Transformers on a range of public benchmarks. In particular, our Focal Transformer models with a moderate size of 51.1M and a larger size of 89.8M achieve 83.6 and 84.0 Top-1 accuracy, respectively, on ImageNet classification at 224x224 resolution. Using Focal Transformers as the backbones, we obtain consistent and substantial improvements over the current state-of-the-art methods for 6 different object detection methods trained with standard 1x and 3x schedules. Our largest Focal Transformer yields 58.7/58.9 box mAPs and 50.9/51.3 mask mAPs on COCO mini-val/test-dev, and 55.4 mIoU on ADE20K for semantic segmentation.

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>
