这是一个简单的示例，因为每个循环的值都相同，但它正在工作。它基本上是您正在使用的代码（唯一的区别是循环和输入文本的实现）。
on run
set theText to "Sample Input"
repeat with i from 2 to 300
tell application "Microsoft Excel"
set value of cell ("k" & (i as string)) to theText
end tell
end repeat
end run
我唯一能猜到的是您的输入文本不是您所期望的。在查看您的代码时，您似乎试图创建一个您自己的函数，称为getInputByClass? 不确定这是否只是您帖子上的拼写错误，但该功能的格式不正确，这可能是您的问题。
这是您的代码的轻微修改......
on run
repeat with i from 2 to 725
tell application "Microsoft Excel" to activate -- these activate lines may not be necessary
tell application "System Events"
keystroke "c" using command down
delay 1
end tell
tell application "Google Chrome" to activate -- these activate lines may not be necessary
tell application "System Events"
keystroke "t" using command down
delay 1
keystroke "https://bookscouter.com/prices.php?isbn="
keystroke "v" using command down
keystroke "&searchbutton=Sell"
delay 1
keystroke return
delay 10
end tell
set theText to getInputByClass("book-prices", 0)
tell application "Microsoft Excel"
set value of cell ("k" & (i as string)) to theText
end tell
tell application "System Events"
keystroke "w" using command down
end tell
end repeat
end run
on getInputByClass(theClass, num)
try
tell application "Google Chrome"
tell active tab of window 1
set input to execute javascript "document.getElementsByClassName('" & theClass & "')[" & num & "].innerHTML;"
end tell
end tell
return input
on error
return "Error getting input"
end try
end getInputByClass
另外一点，我认为您可以对这个脚本进行其他改进。您不必使用keystrokes从 Excel 获取内容并让 Chrome 打开新选项卡并导航到页面。这可以通过编写 Excel 和 Chrome 脚本直接完成。如果您可以摆脱使用System Events，keystroke您的脚本将更加稳定。
例如，您可以使用它，而不是尝试从您在 Excel 中选择的单元格中复制内容。
tell application "Microsoft Excel" to set theText to string value of selection
然后您可以使用它来创建您的最终 URL，如下所示...
set MyURL to "https://bookscouter.com/prices.php?isbn=" & theText & "&searchbutton=Sell"
更新 ！！！
我有更多时间来运行您的代码，而您的问题是您的 javascript 没有在页面上找到该类，它不存在。
我认为您还有一些事情要处理您的代码，因为您似乎要继续打开和关闭相同的页面，这显然是浪费精力。此外，您似乎在以获取内容的方式不断为您的 Excel 工作表定位相同的数据，而不是在函数调用中增加数字。无论如何，下面的更新代码与您的代码相似，但已清理并执行我认为您正在尝试执行的操作。我已将 URL 的开头移到重复循环之外，这将显着提高您正在执行的操作的速度。
对代码进行更深入的返工
on run
tell application "Microsoft Excel" to set theText to string value of selection
set MyURL to "https://bookscouter.com/prices.php?isbn=" & theText & "&searchbutton=Sell"
tell application "Google Chrome" to open location MyURL
do shell script "sleep 1" -- give the tab time to load
tell application "Google Chrome" to set newTab to active tab of window 1
do shell script "sleep 3" -- give the page time to load
repeat with i from 2 to 725
set theText to getInputByClass("book-price-normal", i - 2)
if theText as text is not "Missing Value" then
tell application "Microsoft Excel" to set value of cell ("k" & (i as string)) to theText
else
exit repeat
end if
end repeat
tell application "Google Chrome" to close newTab
end run
on getInputByClass(theClass, num)
try
tell application "Google Chrome"
tell active tab of window 1
set input to execute javascript "document.getElementsByClassName('" & theClass & "')[" & num & "].innerHTML;"
end tell
end tell
return input
on error
return "Error getting input"
end try
end getInputByClass
