我有一个for循环正在使用我的Google表格,但是大约需要5分钟来过滤2100行数据。我已经读过关于使用过滤器以及一起摆脱for循环的知识,但是我对使用Google Script编码非常陌生,还无法完全理解语法。任何建议,不胜感激。
下面的代码:
function Inspect() {a
var sSheet = SpreadsheetApp.getActiveSpreadsheet();
var srcSheet = sSheet.getSheetByName("Inventory");
var tarSheet = sSheet.getSheetByName("Inspections");
var lastRow = srcSheet.getLastRow();
for (var i = 2; i <= lastRow; i++) {
var cell = srcSheet.getRange("A" + i);
var val = cell.getValue();
if (val == true) {
var srcRange = srcSheet.getRange("B" + i + ":I" + i);
var clrRange = srcSheet.getRange("A" + i);
var tarRow = tarSheet.getLastRow();
tarSheet.insertRowAfter(tarRow);
var tarRange = tarSheet.getRange("A" + (tarRow+1) + ":H" + (tarRow+1));
var now = new Date();
var timeRange = tarSheet.getRange("I"+(tarRow+1));
timeRange.setValue(now);
srcRange.copyTo(tarRange);
clrRange.clear();
//tarRange.activate();
timeRange.offset(0, 1).activate();
}
}
};

是的,要加快速度,您需要首先获取所有值,并将逻辑应用于获取的2D数组而不是单元格,最后,将使用setValues来更新工作表。我会选择这样的东西:
function Inspect() {
var sSheet = SpreadsheetApp.getActiveSpreadsheet();
var srcSheet = sSheet.getSheetByName("Inventory");
var tarSheet = sSheet.getSheetByName("Inspections");
var srcLastRow = srcSheet.getLastRow();
var tarLastRow = tarSheet.getLastRow();
var srcArray = srcSheet.getRange(1,1,srcLastRow,9).getValues();//(A1:I(lastrow))
var tarArray = tarSheet.getRange(1,1,tarLastRow,9).getValues();//(A1:I(lastrow))
for (var i = 1; i < srcArray.length; i++) {
var val = srcArray[i][0];
if (val == true) {
var copyValues = srcArray[i].slice(1);//Get all elements from the row excluding first column (srcSheet.getRange("B" + i + ":I" + i);)
var now = new Date();
copyValues[8]=now;//set the time on column 9 (array starts at position 0!)
var tarNewLine = copyValues;
tarArray.push(tarNewLine);
//clear values on source (except column A):
for(var j=1;j<srcArray[i].length;j++){
srcArray[i][j]="";
}
}
}
tarSheet.clear();
tarSheet.getRange(1, 1,tarArray.length,tarArray[0].length).setValues(tarArray);
srcSheet.clear();
srcSheet.getRange(1, 1,srcArray.length,srcArray[0].length).setValues(srcArray);
};

不是for
循环,而是那些使您的代码变慢的调用。取而代之的是,尽可能多地使用数组。如果循环是嵌套的,则成为一个问题-这也是您应避免的事情。
示例如何在循环外执行对SpreadsheetApp
的大多数调用并使用数组:
function Inspect() {
var sSheet = SpreadsheetApp.getActiveSpreadsheet();
var srcSheet = sSheet.getSheetByName("Inventory");
var tarSheet = sSheet.getSheetByName("Inspections");
var lastRow = srcSheet.getLastRow();
var Acolumn = srcSheet.getRange("A2:A" + lastRow);
var Avalues = Acolumn.getValues();
var srcRange = srcSheet.getRange("B2:I" + lastRow);
var srcValues = srcRange.getValues();
var array = [];
var now = new Date();
for (var i = 0; i < lastRow-1; i++) {
var val = Avalues[i][0];
if (val == true) {
srcValues[i].push(now);
array.push(srcValues[i]);
var clrRange = Acolumn.getCell(i+1, 1);
clrRange.clear();
}
}
var tarRow = tarSheet.getLastRow();
tarSheet.insertRowAfter(tarRow);
if(array.length!=0){
var tarRange = tarSheet.getRange("A" + (tarRow+1) + ":I" + (tarRow + array.length));
tarRange.setValues(array);
}
};
