目前，我有一个Google脚本，我必须在一个工作表中保护多个人的多个范围。
以下是我现在的代码：
function setPermissions () {
for (var number = 1; number < 30; number++) {
var n = number.toString();
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(n);
var protectionDescription = 'Initial Sheet Protection - Script'
var protectedRangesArray = [
'A1:F5',
'G1:G4',
'H1:K5',
'L1:L2',
'M1:N5',
'A6:P8',
'A7:B61',
'A62:P62',
'O9:O61',
'F9:F11',
'A1:P2'
];
for (var i = 0; i < protectedRangesArray.length; i++) {
var range = sheet.getRange(protectedRangesArray[i]);
var protection = range.protect().setDescription(protectionDescription);
protection.removeEditors(protection.getEditors());
};
// = Everything else is repeated from here so you really only need to look at the above code.
var protectedRangesArray = [
'C9:E61',
'F12:F61',
'G9:H61',
'P9:P61',
'O3:P5'
];
for (var i = 0; i < protectedRangesArray.length; i++) {
var range = sheet.getRange(protectedRangesArray[i]);
var protection = range.protect().setDescription(protectionDescription);
protection.addEditors([
saEmail,
amEmail,
bmEmail,
meEmail
]);
protection.removeEditors([
brEmail
]);
};
// =====
var protectedRangesArray = [
'K9:N61'
];
for (var i = 0; i < protectedRangesArray.length; i++) {
var range = sheet.getRange(protectedRangesArray[i]);
var protection = range.protect().setDescription(protectionDescription);
protection.addEditors([
bmEmail,
brEmail
]);
protection.removeEditors([
saEmail,
amEmail,
meEmail
]);
};
// =====
var protectedRangesArray = [
'G5:G5'
];
for (var i = 0; i < protectedRangesArray.length; i++) {
var range = sheet.getRange(protectedRangesArray[i]);
var protection = range.protect().setDescription(protectionDescription);
protection.addEditors([
amEmail,
bmEmail,
meEmail
]);
protection.removeEditors([
saEmail,
brEmail
]);
};
// =====
var protectedRangesArray = [
'L3:L3'
];
for (var i = 0; i < protectedRangesArray.length; i++) {
var range = sheet.getRange(protectedRangesArray[i]);
var protection = range.protect().setDescription(protectionDescription);
protection.addEditors([
amEmail,
bmEmail,
meEmail
]);
protection.removeEditors([
saEmail,
brEmail
]);
};
// =====
var protectedRangesArray = [
'L4:L4'
];
for (var i = 0; i < protectedRangesArray.length; i++) {
var range = sheet.getRange(protectedRangesArray[i]);
var protection = range.protect().setDescription(protectionDescription);
protection.addEditors([
bmEmail,
meEmail
]);
protection.removeEditors([
saEmail,
amEmail,
brEmail
]);
};
// =====
var protectedRangesArray = [
'L5:L5',
'I9:J61'
];
for (var i = 0; i < protectedRangesArray.length; i++) {
var range = sheet.getRange(protectedRangesArray[i]);
var protection = range.protect().setDescription(protectionDescription);
protection.addEditors([
meEmail
]);
protection.removeEditors([
saEmail,
amEmail,
bmEmail,
brEmail
]);
};
};
};
可以理解，代码需要非常很长时间。
我想弄清楚的是如何减少我在整个脚本中进行的getRange()调用次数。据我所知，这极大地减慢了脚本的速度。
在将var protection = range[0][0].protect().setDescription(protectionDescription);定义为var range之后，我尝试sheet.getRange(1,1,62,16)，但它提供了错误无法从未定义的读取属性“0”。
有没有加速这个功能？现在，我一次只做一张纸（每张纸大约需要5分钟）。
编辑：以下是关心的任何人的更新（以及更快的代码）（感谢BMcV）：
function setPermissions() {
var worksheet = SpreadsheetApp.getActiveSpreadsheet();
var protectionDescription = 'Initial Sheet Protection - Script';
var protectedRangesArray = [];
var addEditorsArray = [];
var removeEditorsArray = [];
for (var number = 0; number < 30; number++) {
var sheet = worksheet.getSheetByName(number.toString());
protectedRangesArray = [
[//0
'A1:F5',
'G1:G4',
'H1:K5',
'L1:L2',
'M1:N5',
'A6:P8',
'A7:B61',
'A62:P62',
'O9:O61',
'F9:F11',
'A1:P2'],

addEditorsArray = [
[], //0

[amEmail, bmEmail, meEmail], //3
[amEmail, bmEmail, meEmail], //4

];
removeEditorsArray = [
[saEmail, amEmail, bmEmail, brEmail, meEmail], //0
[brEmail], //1
[saEmail, amEmail, meEmail], //2
[saEmail, brEmail], //3
[saEmail, brEmail], //4
[saEmail, amEmail, brEmail], //5
[saEmail, amEmail, bmEmail, brEmail] //6
];
protectRanges(sheet, protectionDescription, protectedRangesArray, addEditorsArray, removeEditorsArray)
};
};
function protectRanges(sheet, protectionDescription, protectedRangesArray, addEditorsArray, removeEditorsArray) {
var i = 0, n,
len = protectedRangesArray.length,
range, protection;
for (i; i < len; i++) {
n = 0
for (n; n < protectedRangesArray[i].length; n++) {
range = sheet.getRange(protectedRangesArray[i][n]);
protection = range.protect().setDescription(protectionDescription);
protection.addEditors(addEditorsArray[i]);
protection.removeEditors(removeEditorsArray[i]);
}
}
}

有一些东西可能有助于使脚本更有效，更有可能，更快。
利用hoisting。在此脚本的许多方面，变量定义了多次。这样做会更好：
var number = 1; // Some code here involving number
number = 10; // notice no var at the start!
此功能也应分为几个辅助功能。这将有助于使您的代码更易读，更易于维护。
function protectRanges(sheet, protectionDescription, protectedRangesArray) {
var i = 0,
len = protectedRangesArray.length,
range, protection;
for (i; i < len; i++) {
range = sheet.getRange(protectedRangesArray[i]);
protection = range.protect().setDescription(protectionDescription);
protection.removeEditors(protection.getEditors());
}
}
这样，至少你不必一次又一次地编写代码。这个概念叫做DRY（不要重复自己）。尽可能将重复代码移动到单独的函数中。现在，找到提高性能的方法会更容易。
可能有用的一件事是将电子表格定义移到循环之外。目前，SpreadsheetApp.getActiveSpreadsheet()被调用30次，只需要被调用一次。
主要是通常简化功能。
