上例子

flag = true;   //假设不重复；
let arr = [{ settingName: '渠道客户订单', settingCode: 'A1' },{ settingName: '户订单', settingCode: 'A1' },];for(let i = 0;i < arr.length-1;i++){ //循环开始元素 for(let j = i + 1;j < arr.length;j++){ //循环后续所有元素 //如果相等，则重复 if(arr[i].settingName == arr[j].settingName){ flag = false; //设置标志变量为重复 console.log("重复的值为",arr[i].settingName);break;      //结束循环 }} 
}

然后再根据这个外层的flag 做一些数据组装

（ 可以做一下封装处理。const checkIsRepeat = (arr) => {let flag = true; //假设不重复for (let i = 0; i < arr.length - 1; i++) {//循环开始元素for (let j = i + 1; j < arr.length; j++) {//循环后续所有元素: 如果相等，则重复if (arr[i] == arr[j]) {flag = false; //设置标志变量为重复break; //结束循环}}}//判断标志变量if (flag) {console.log('数组没有重复的元素');} else {console.log('数组含有重复的元素');}};
）

如上图所是 FormList 是一个数组

// 订货设置 -取消
const Cancelvalues = await this.formRef.current.validateFields();
const { shouldPayRules } = Cancelvalues; // 拿到Cancelvalues 里面的shouldPayRules 数组数据
let tableArr: any = [];
let unorderSettingArr = []; // 取消订货设置
if (shouldPayRules != null && shouldPayRules.length != 0) {const DuplicateDelete = shouldPayRules?.map((value) => {return {settingName: value.settingName.udcValueName || value.settingName.valDesc,settingCode: value.settingName.udcValueCode || value.settingName.udcVal,};});let shouldFlag = true; //假设不重复for (let i = 0; i < DuplicateDelete.length - 1; i++) {//循环开始元素for (let j = i + 1; j < DuplicateDelete.length; j++) {//循环后续所有元素:如果相等，则重复if (DuplicateDelete[i].settingCode == DuplicateDelete[j].settingCode) {shouldFlag = false; //设置标志变量为重复break; //结束循环}}}//判断标志变量if (shouldFlag) {unorderSettingArr = shouldPayRules;} else {ElNotification({type: 'error',message: '取消订单时间配置不允许相同',});return false;}tableArr = unorderSettingArr.map((item) => {return {businessType: 'DH',settingCode: item.settingName.udcValueCode || item.settingName.udcVal || '',settingName: item.settingName.udcValueName || item.settingName.valDesc || '',settingType: '01',settingVal: item.settingVal || '',id: item.id || null,};});
} else {ElNotification({type: 'error',message: '请新增-取消订单时间配置',});return false;
}
// tableArr  就是我们处理的数据了，然后看需要，参数赋值就行
假设一个params = { houduanjieshoucasnhu: tableArr   } ok
