字符串 转 Object

        

          const strToObj = (str: string)=>{
            if(!str) return {};
            const objArr = str?.replace(/\{|\}|\s/g,'')?.split(',');
            const obj: Record<string,any> = {};
            objArr.forEach((its: any)=>{
              const oneArr: string[] = its?.split(':');
              let val = oneArr[1]?.replace(/'|"/g,'');
                if(oneArr.length > 2){
                  val += `:${oneArr[2]?.replace(/'|"/g,'')}`;
                }
              obj[oneArr[0]] = val;
            });
            return obj;
          };
        
      

字符串 转 Array

        

          const strToArray = (str: string)=>{
            if(!str) return [];
            const objArr = str?.replace(/\[|\]|\s/g,'')?.split('},');
            const allArr: any[] = [];
            objArr.forEach((item: any, index: number)=>{
              const oneArr = item.replace(/\{|\}/g,'')?.split(',');
              oneArr.forEach((its: any)=>{
                const twoArr: string[] = its?.split(':');
                let val = twoArr[1]?.replace(/'|"/g,'');
                if(twoArr.length > 2){
                  val += `:${twoArr[2]?.replace(/'|"/g,'')}`;
                }
                allArr[index] ??= {};
                allArr[index][twoArr[0]] = val;
              });
            });
            return allArr;
          };
