好的，我可以回答这个问题。以下是
使用 Vue 和 OpenLayers 编写自定义
全屏控件的代码示例：
<template>
<div class="fullscreen-control ol-unselectable ol-control">
<button @click="toggleFullscreen"
:title="isFullscreen ? '
退出全屏'
: '
全屏'">
<i
:class="isFullscreen ? 'fa fa-compress'
: 'fa fa-expand'"></i>
</button>
</div>
</template>
<script>
export default {
name
: 'FullscreenControl',
data() {
return {
isFullscreen
: false
}
},
mounted() {
document
.addEventListener('fullscreenchange', this
.handleFullscreenChange)
document
.addEventListener('webkitfullscreenchange', this
.handleFullscreenChange)
document
.addEventListener('mozfullscreenchange', this
.handleFullscreenChange)
document
.addEventListener('MSFullscreenChange', this
.handleFullscreenChange)
},
beforeDestroy() {
document
.removeEventListener('fullscreenchange', this
.handleFullscreenChange)
document
.removeEventListener('webkitfullscreenchange', this
.handleFullscreenChange)
document
.removeEventListener('mozfullscreenchange', this
.handleFullscreenChange)
document
.removeEventListener('MSFullscreenChange', this
.handleFullscreenChange)
},
methods
: {
toggleFullscreen() {
const elem = document
.documentElement
if (!this
.isFullscreen) {
if (elem
.requestFullscreen) {
elem
.requestFullscreen()
} else if (elem
.webkitRequestFullscreen) {
elem
.webkitRequestFullscreen()
} else if (elem
.mozRequestFullScreen) {
elem
.mozRequestFullScreen()
} else if (elem
.msRequestFullscreen) {
elem
.msRequestFullscreen()
}
} else {
if (document
.exitFullscreen) {
document
.exitFullscreen()
} else if (document
.webkitExitFullscreen) {
document
.webkitExitFullscreen()
} else if (document
.mozCancelFullScreen) {
document
.mozCancelFullScreen()
} else if (document
.msExitFullscreen) {
document
.msExitFullscreen()
}
}
},
handleFullscreenChange() {
this
.isFullscreen = !this
.isFullscreen
}
}
}
</script>
<style scoped>
.fullscreen-control {
position
: absolute;
top
: 10px;
right
: 10px;
z-index
: 100;
}
.fullscreen-control button {
background-color
: #fff;
border
: none;
border-radius
: 3px;
box-shadow
: 0 1px 4px rgba(0, 0, 0, 0

}
.fullscreen-control button

}
.fullscreen-control button i {
font-size

}
</style>
