async openDialog () { console.log(this.objFormData, '编辑信息') // 获取所有案由的违规条款选项和依据数据 const optionsMap = new Map() const basisMap = new Map() await Promise.all(this.objFormData.accordList.map(async accord => { // console.log(accord, '打印') const { data: optionData } = await getLawRules(accord.violationAccord) optionsMap.set(accord.violationAccord, lawTreeFilter(optionData)) basisMap.set(accord.violationAccord, accord.accordBasis) })) // 处理条例数据 const gistList = [] for (const accord of this.objFormData.accordList) { accord.accordDetail.forEach(item => { let labels = item.violationClause.split("-").map(str => str.trim()).filter(Boolean) // console.log(labels, 'labels') const illegalOptions = accord.illegalOptions || optionsMap.get(accord.violationAccord) const ruleIdList = [] let options = illegalOptions for (const label of labels) { const option = options.find(opt => opt.label === label) if (option) { ruleIdList.push(option.value) options = option.children } } // console.log(ruleIdList,'ruleIdList') // console.log(options,'options') // 添加选择的数据到数组中 // const selectedData = { // violationAccord: accord.violationAccord, // violationAccordText: accord.violationAccordText, // illegalValue: ruleIdList // } // gistList.push(selectedData) // 添加数据到回显数据中 const elRuleList = [{ illegalValue: ruleIdList }]; console.log(elRuleList,'hhhhhh') const echoData = { gistValue: accord.violationAccordText, ruleList: elRuleList, illegalOptions: illegalOptions, basis: basisMap.get(accord.violationAccord) } this.gistList.push(echoData) }) } },这个方法中，这个 accord.violationAccordText值相等的把他们对应的elRuleList这个值放到一个ruleList里面

好的，你可以使用 Map 数据结构来处理相同 violationAccordText 值的情况，将 echoData 存储在 Map 中，以 violationAccordText 作为键名。如果已经存在相同键名的数据，则将其 elRuleList 值合并到已存在数据的 ruleList 中。可以参考下面的代码：

async openDialog() {
  console.log(this.objFormData, "编辑信息");

  const optionsMap = new Map();
  const basisMap = new Map();

  await Promise.all(
    this.objFormData.accordList.map(async (accord) => {
      const { data: optionData } = await getLawRules(accord.violationAccord);
      optionsMap.set(accord.violationAccord, lawTreeFilter(optionData));
      basisMap.set(accord.violationAccord, accord.accordBasis);
    })
  );

  const echoDataMap = new Map();
  for (const accord of this.objFormData.accordList) {
    accord.accordDetail.forEach((item) => {
      const labels = item.violationClause
        .split("-")
        .map((str) => str.trim())
        .filter(Boolean);

      const illegalOptions =
        accord.illegalOptions || optionsMap.get(accord.violationAccord);
      const ruleIdList = [];
      let options = illegalOptions;
      for (const label of labels) {
        const option = options.find((opt) => opt.label === label);
        if (option) {
          ruleIdList.push(option.value);
          options = option.children;
        }
      }

      const elRuleList = [{ illegalValue: ruleIdList }];
      const echoData = {
        gistValue: accord.violationAccordText,
        ruleList: elRuleList,
        illegalOptions: illegalOptions,
        basis: basisMap.get(accord.violationAccord),
      };

      if (echoDataMap.has(accord.violationAccordText)) {
        // 如果已经存在相同键名的数据，则将其 elRuleList 值合并到已存在数据的 ruleList 中
        const existingEchoData = echoDataMap.get(accord.violationAccordText);
        existingEchoData.ruleList.push(...elRuleList);
      } else {
        echoDataMap.set(accord.violationAccordText, echoData);
      }
    });
  }

  // 将 Map 中的数据转为数组
  this.gistList = Array.from(echoDataMap.values());
},

希望这个修改能够帮到你。
