每100行将行写入文件

• 问答

这是我的代码，它从文件中读取20万行。

包含正确URL代码的行将其写入scope.getgrouped = function (arrlst) { var Names = []; //get Names angular.forEach(arrlst,function (value,key) { if (Names.indexOf(value.Name) === -1) Names.push(value.Name); }); var resultArr = [] angular.forEach(Names,function (Name) { //get record for the current Name var lstcurrent = []; lstcurrent.length = 0; angular.forEach(arrlst,function (row) { if (row.Name === Name) { lstcurrent.push(row); } }); if (lstcurrent.length === 1) resultArr.push(lstcurrent[0]); else { for (var i = 0; i < 4; i++) { if (lstcurrent.length > 0 && lstcurrent[0]["id"].length > 1) { resultArr.push(lstcurrent[0]); lstcurrent.splice(0,1); } if (lstcurrent.length === 1) { resultArr.push(lstcurrent[0]); break; } for (var j = 1; j < lstcurrent.length; j++) { if ((lstcurrent[0].Country.indexOf(lstcurrent[j].Country[0]) !== -1) && (lstcurrent[0].Unit.indexOf(lstcurrent[j].Unit[0]) !== -1) && i == 0) { if (lstcurrent[0].Department.indexOf(lstcurrent[j].Department[0]) === -1) lstcurrent[0].Department.push(lstcurrent[j].Department[0]); lstcurrent[0].id.push(lstcurrent[j].id[0]); lstcurrent.splice(j,1); j = j - 1; continue; } //Country + Department else if ((lstcurrent[0].Country.indexOf(lstcurrent[j].Country[0]) !== -1) && (lstcurrent[0].Department.indexOf(lstcurrent[j].Department[0]) !== -1) && i === 1) { if (lstcurrent[0].Unit.indexOf(lstcurrent[j].Unit[0]) === -1) lstcurrent[0].Unit.push(lstcurrent[j].Unit[0]); lstcurrent[0].id.push(lstcurrent[j].id[0]); lstcurrent.splice(j,1); j = j - 1; continue; } //Unit + Department else if ((lstcurrent[0].Unit.indexOf(lstcurrent[j].Unit[0]) !== -1) && (lstcurrent[0].Department.indexOf(lstcurrent[j].Department[0]) !== -1) && i === 2) { if (lstcurrent[0].Country.indexOf(lstcurrent[j].Country[0]) === -1) lstcurrent[0].Country.push(lstcurrent[j].Country[0]); lstcurrent[0].id.push(lstcurrent[j].id[0]); lstcurrent.splice(j,1); j = j - 1; continue; } else if (i > 2) { if (lstcurrent.length === 1) { resultArr.push(lstcurrent[0]); } else { resultArr.push(lstcurrent[j - 1]); lstcurrent.splice(j - 1,1); i = 0; break; } } } } } })}; ，包含错误URL代码的行将其写入true.txt。

代码在读取所有行时将这些文件写入。我想对其做一个小的更改：当代码读取一百行时，它会在错误和正确的wrong.txt上进行更新。有人指导我怎么可能吗？

file.txt

这就是您的答案，只需添加同花顺
