我正在使用这段代码：

set myJSvar to do JavaScript javaScriptVar in document 1

display alert myJSvar

尝试：

set javaScriptVar to "var body = document.body; html = document.documentElement; var height = Math.max(body.scrollHeight, body.offsetHeight, html.scrollHeight, html.offsetHeight); height;"

tell application "Safari" to set myJSvar to do JavaScript javaScriptVar in document 1
