Some of goals of this project worth noting include:\n\n* Be lightweight, powerful and easy to use\n* Work on any image type\n* Add loading class while image is loading\n* Supports both of Vue 1.0 and Vue 2.0\n\n\n\n# Table of Contents\n\n* [___Demo___](#demo)\n* [___Requirements___](#requirements)\n* [___Installation___](#installation)\n* [___Usage___](#usage)\n * [___Constructor Options___](#constructor-options)\n * [___Implementation___](#implementation)\n * [___Basic___](#basic)\n * [___Css state___](#css-state)\n* [___Methods___](#methods)\n * [__Event hook__](#event-hook)\n * [__LazyLoadHandler__](#lazyloadhandler)\n * [__Performance__](#performance)\n* [___Authors && Contributors___](#authors-&&-Contributors)\n* [___License___](#license)\n\n\n# Demo\n\n[___Demo___](http://hilongjw.github.io/vue-lazyload/)\n\n# Requirements\n\n- [Vue.js](https://github.com/vuejs/vue) `1.x` or `2.x`\n\n\n# Installation\n\n## npm\n\n```bash\n\n$ npm i vue-lazyload -S\n\n```\n\n## CDN\n\nCDN: [https://unpkg.com/vue-lazyload/vue-lazyload.js](https://unpkg.com/vue-lazyload/vue-lazyload.js)\n\n```html\n\n\n\n```\n\n# Usage\n\nmain.js:\n\n```javascript\n\nimport Vue from 'vue'\nimport App from './App.vue'\nimport VueLazyload from 'vue-lazyload'\n\nVue.use(VueLazyload)\n\n// or with options\nVue.use(VueLazyload, {\n preLoad: 1.3,\n error: 'dist/error.png',\n loading: 'dist/loading.gif',\n attempt: 1\n})\n\nnew Vue({\n el: 'body',\n components: {\n App\n }\n})\n```\n\ntemplate:\n\n```html\n\n - \n

\n```\n\nuse `v-lazy-container` work with raw HTML\n\n```html\n\n```\n\ncustom `error` and `loading` placeholder image\n\n```html\n\n```\n\n```html\n\n```\n\n## Constructor Options\n\n|key|description|default|options|\n|:---|---|---|---|\n| `preLoad`|proportion of pre-loading height|`1.3`|`Number`|\n|`error`|src of the image upon load fail|`'data-src'`|`String`\n|`loading`|src of the image while loading|`'data-src'`|`String`|\n|`attempt`|attempts count|`3`|`Number`|\n|`listenEvents`|events that you want vue listen for|`['scroll', 'wheel', 'mousewheel', 'resize', 'animationend', 'transitionend', 'touchmove']`| [Desired Listen Events](#desired-listen-events) |\n|`adapter`| dynamically modify the attribute of element |`{ }`| [Element Adapter](#element-adapter) |\n|`filter`| the image's listener filter |`{ }`| [Image listener filter](#image-listener-filter) |\n|`lazyComponent`| lazyload component | `false` | [Lazy Component](#lazy-component)\n| `dispatchEvent`|trigger the dom event|`false`|`Boolean`|\n| `throttleWait`|throttle wait|`200`|`Number`|\n| `observer`|use IntersectionObserver|`false`|`Boolean`|\n| `observerOptions`|IntersectionObserver options|{ rootMargin: '0px', threshold: 0.1 }|[IntersectionObserver](#intersectionobserver)|\n| `silent`|do not print debug info|`true`|`Boolean`|\n\n### Desired Listen Events\n\nYou can configure which events you want vue-lazyload by passing in an array\nof listener names.\n\n```javascript\nVue.use(VueLazyload, {\n preLoad: 1.3,\n error: 'dist/error.png',\n loading: 'dist/loading.gif',\n attempt: 1,\n // the default is ['scroll', 'wheel', 'mousewheel', 'resize', 'animationend', 'transitionend']\n listenEvents: [ 'scroll' ]\n})\n```\n\nThis is useful if you are having trouble with this plugin resetting itself to loading\nwhen you have certain animations and transitions taking place\n\n\n### Image listener filter\n\ndynamically modify the src of image\n\n```javascript\nVue.use(vueLazy, {\n filter: {\n progressive (listener, options) {\n const isCDN = /qiniudn.com/\n if (isCDN.test(listener.src)) {\n listener.el.setAttribute('lazy-progressive', 'true')\n listener.loading = listener.src + '?imageView2/1/w/10/h/10'\n }\n },\n webp (listener, options) {\n if (!options.supportWebp) return\n const isCDN = /qiniudn.com/\n if (isCDN.test(listener.src)) {\n listener.src += '?imageView2/2/format/webp'\n }\n }\n }\n})\n```\n\n\n### Element Adapter\n\n```javascript\nVue.use(vueLazy, {\n adapter: {\n loaded ({ bindType, el, naturalHeight, naturalWidth, $parent, src, loading, error, Init }) {\n // do something here\n // example for call LoadedHandler\n LoadedHandler(el)\n },\n loading (listender, Init) {\n console.log('loading')\n },\n error (listender, Init) {\n console.log('error')\n }\n }\n})\n```\n\n### IntersectionObserver\n\nuse [Intersection Observer](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API) to to improve performance of a large number of nodes.\n\n```javascript\nVue.use(vueLazy, {\n // set observer to true\n observer: true,\n\n // optional\n observerOptions: {\n rootMargin: '0px',\n threshold: 0.1\n }\n})\n```\n\n\n### Lazy Component\n```javascript\nVue.use(VueLazyload, {\n lazyComponent: true\n});\n```\n\n```html\n\n ![]()
\n\n\n\n```\n\n\n## Implementation\n\n### Basic\n\nvue-lazyload will set this img element's `src` with `imgUrl` string\n\n```html\n\n\n\n \n

The listener will be removed once it triggers for the first time.\n- `$off` Remove event listener(s).\n\n#### `vm.$Lazyload.$on`\n\n#### Arguments:\n\n * `{string} event`\n * `{Function} callback`\n\n#### Example\n\n```javascript\nvm.$Lazyload.$on('loaded', function ({ bindType, el, naturalHeight, naturalWidth, $parent, src, loading, error }, formCache) {\n console.log(el, src)\n})\n```\n\n#### `vm.$Lazyload.$once`\n\n#### Arguments:\n\n * `{string} event`\n * `{Function} callback`\n\n#### Example\n\n```javascript\nvm.$Lazyload.$once('loaded', function ({ el, src }) {\n console.log(el, src)\n})\n```\n\n#### `vm.$Lazyload.$off`\n\nIf only the event is provided, remove all listeners for that event\n\n#### Arguments:\n\n * `{string} event`\n * `{Function} callback`\n\n#### Example\n\n```javascript\nfunction handler ({ el, src }, formCache) {\n console.log(el, src)\n}\nvm.$Lazyload.$on('loaded', handler)\nvm.$Lazyload.$off('loaded', handler)\nvm.$Lazyload.$off('loaded')\n```\n\n### LazyLoadHandler\n\n`vm.$Lazyload.lazyLoadHandler`\n\nManually trigger lazy loading position calculation\n\n#### Example\n\n```javascript\n\nthis.$Lazyload.lazyLoadHandler()\n\n```\n\n### Performance\n\n```javascript\nthis.$Lazyload.$on('loaded', function (listener) {\n console.table(this.$Lazyload.performance())\n})\n```\n\n\n\n### Dynamic switching pictures\n\n```vue\n ![]()
