预览组件 PicturePreview

<!-- el-upload组件 - list-type="picture" 时，文件预览展示优化 -->
<template><div class="file_container"><div class="file"><el-imagev-if="/(gif|jpg|jpeg|png|GIF|JPG|JPEG|PNG)$/.test(fileType)":src="file.url":preview-src-list="[file.url]"/><i v-else class="el-icon-tickets" /></div><div class="name">{{ file.name }}</div><i class="el-icon-close" @click="$emit('remove', file)" /></div>
</template><script>javascript">
export default {name: 'PicturePreview',components: {},props: {file: {type: Object,required: true}},data() {return {}},computed: {fileType() {return this.file.name.split('.').pop()}},watch: {},created() {},methods: {}
}
</script><style lang='scss' scoped>
