若依框架给字典字段新增color值，并且实现下拉列表选项进行颜色设置

首先获取所要新增的字典，并且根据字典的value值选取对应的颜色参数

this.getDicts("risk_level").then(response => {const color = {mild:'#F1F4BD',moderate:'#EEC920',severe:'#FF6C0D',very_severe:'#FF0000',no_harm:'green'};const res = response.data.map((item)=>{return {color:color[item.dictValue],...item}});this.risk_level_color = res;console.log(this.risk_level_color);
});

前端显示

el-option渲染，使用v-html进行渲染

<el-form-item label="风险等级" prop="riskLevel"><el-selectv-model="queryParams.riskLevel"placeholder="风险等级"clearablestyle="width: 240px"ref="measureParamLevelId"@change="chageTextColor($event,'measureParamLevelId')"><el-optionv-for="dict in risk_level_color":key="dict.dictValue":label="dict.dictLabel":value="dict.dictValue"v-html="'<span style=color:'+dict.color+'>'+dict.dictLabel+'</span>'"/></el-select></el-form-item>

method方法

chageTextColor($event, selectedRef) {const color = this.risk_level_color.filter((item)=>{return item.dictValue==$event})[0].color;// 改变下拉框颜色值this.$refs[selectedRef].$el.children[0].children[0].style.color = '' + color + ''},
