<template>
    <div v-bind:ref="im.register()">
        <h2>{{im.isReady ? "I'm Ready" : "Loading..."}}</h2>
        <h2>{{im.readyCount}}/{{im.totalCount}}</h2>

    </div>
</template>
<script>
import { useReadyElement } from "@egjs/vue-imready";

export default {
    setup() {
        const im = useReadyElement({
            selector: "img",
        });
        return {
            im,
        }

}
</script>

• Use preReadyElement (usePreReadyElement: true, usePreReady: true)

<template>
    <div v-bind:ref="im.register()">
        <h2>{{im.isPreReady ? "I'm PreReady" : "Loading..."}}</h2>
        <h2>{{im.preReadyCount}}/{{im.totalCount}}</h2>

        });
        return {
            im,
        }

        <img src=".." />
    </div>
</template>
<script>
import { usePreReady } from "@egjs/vue-imready";

export default {
    setup() {
        const im = usePreReady({
            selector: "img",
        });
        return {
            im,
        }
    }
}
</script>

• Use useImReady (*: true)

<template>
    <div v-bind:ref="im.register()">
        <h2>{{im.isReady ? "I'm Ready" : "Loading..."}}</h2>
        <h2>{{im.readyCount}}/{{im.totalCount}}</h2>
        <h2>{{im.isPreReady ? "I'm PreReady" : "Loading..."}}</h2>

export default {
    setup() {
        const im = useImReady({
            selector: "img",
        });
        return {
            im,
        }
    }
}
</script>

• If you use data-width and data-height attributes, the size of self, child image, and video elements is automatically adjusted until loading is complete.

<div data-width="100" data-height="100">
   <img src="..." />
   <img src="..." />
   <img src="..." />
</div>

• If you use data-skip="ture" attribute, you can omit it even if there are images in itself and child image, and video elements.

<div data-skip="true">
   <img src="..." />
   <img src="..." />
   <img src="..." />
</div>

Events

• preReadyElement: An event occurs when the element is pre-ready (when the size is known)
• preReady: An event occurs when all element are pre-ready (when the size is known)
• readyElement: An event occurs when all element are ready
• ready: An event occurs when all element are ready

Sequence of events

• If there is no data size attribute or loading attribute

(preReadyElement => readyElement) x N => preReady => ready

• If there is a data size attribute or a loading attribute

preReadyElement * N => (preReadyElement => readyElement) x M => preReady => readyElement(isPreReadyOver: true) x N => ready
