computed: { uniqueTags() { if (!this.PDFTiInfo.exam.Tilist) { return []; } {{ uniqueTags.join(', ') }} {{ uniqueTagsPercentage }} 这里头我想要class为proportion的样式随着uniqueTagsPercentage的百分比大小而填充对应的颜色 //将所有知识点存入到数组 const tags = this.PDFTiInfo.exam.Tilist.map(tag => tag.Taglist[1]); //Set去重一下 const uniqueTags = [...new Set(tags)]; console.log(uniqueTags) return uniqueTags }, uniqueTagsPercentage() { if (!this.PDFTiInfo.exam.Tilist) { return 0; } const uniqueTagsCount = this.uniqueTags.length; const totalTagsCount = this.PDFTiInfo.exam.Tilist.length; const percentage = (uniqueTagsCount / totalTagsCount) * 100; return percentage.toFixed(2); } },

<div class="proportion" :style="proportionStyle">{{ uniqueTags.join(', ') }}</div> 这样，当uniqueTagsPercentage的值改变时，class为proportion的元素的背景颜色将动态地填充相应的颜色渐变。
