vue将formData转换为json格式

		//this.selectionRows这个是提前写好的数据
        var arr={
    
    };
        var arrayes=[];
        for (let i = 0; i < this.selectionRows.length; i++) {
    
    
          var formData = new FormData();
          formData.append("partNumber",this.selectionRows[i].partNumber);
          formData.append("supplierCode",this.selectionRows[i].supplierCode);
          formData.append("updatedBy",this.selectionRows[i].updatedBy);
          //formData.forEach((value, key) => arr[key] = value)将formData转换为json格式
          formData.forEach((value, key) => arr[key] = value)
          arrayes.push(arr)
        }
        console.log(arrayes,"arrayes")

效果如下
