我对此很陌生，所以这可能是一个愚蠢的问题，但是....

我正试图通过单击链接来从网站上进行下载，但我认为我的代码不适合AppleScript.

The script opens the right website, but when I try to get it to download the file I need by clicking "export data" the code below doesnt seem to do anything, and am not sure what I am missing/did wrong. No error code. Just doesnt do anything.

_{Note: The example AppleScript code is just that and does not contain any error handling as may be appropriate. The onus is upon the user to add any error handling as may be appropriate, needed or wanted. Have a look at the try statement and error statement in the AppleScript Language Guide. See also, Working with Errors. Additionally, the use of the delay command may be necessary between events where appropriate, e.g. delay 0.5, with the value of the delay set appropriately.}
