我有一个Google Sheets脚本,该脚本应该从API抓取数据,但出现错误
TypeError:无法读取未定义的属性“ length”(第5行,文件“ draftOrder”)
如何解决此错误?我已经好多年没有接触过该脚本了,所以我不确定是什么原因造成的。
function draftOrder(ownerRange, numRounds) {
var output = [];
var owners = [];
for (var i = 0; i < ownerRange.length; i++) {
if (ownerRange[i][0] !== '') {
owners.push(ownerRange[i][0]);
}
}
for (var i = 0; i < numRounds; i++) {
if (i % 2 == 0) {
output = output.concat(owners);
} else {
output = output.concat([].concat(owners).reverse());
}
}
return output;
}
在此先感谢您提供的任何帮助。干杯!

function draftOrder(ownerRange, numRounds) {
var output = [];
var owners = [];
if(ownerRange && numRounds) {//checking for valid inputs
for (var i = 0; i < ownerRange.length; i++) {
if (ownerRange[i][0] !== '') {
owners.push(ownerRange[i][0]);
}
}
for (var i = 0; i < numRounds; i++) {
if (i % 2 == 0) {
output = output.concat(owners);
} else {
output = output.concat([].concat(owners).reverse());
}
}
return output;
}else{
SpreadsheetApp.getUi().alert('Invalid Inputs')
}
}
