Question

tell application "Safari"
    set theVar to (do JavaScript "
var a = 
document.getElementById('unitsdiv').getElementsByClassName('even');
var b = []
for (var i = 0; i < a.length; i++) {
    b[i] = a[i].textContent;
};
console.log(b.length);  \\ Returns 2
console.log(b[1]);      \\ Returns item 2 of Array
console.log(b[0]);      \\ Returns item 1 of Array
b;                      \\ Shows both items in Safari Console
") in document 1
end tell

log theVar -- Missing Value

代码在Safari控制台中按预期工作。我还尝试在运行带有set theVar to {}的do Javascript命令之前初始化列表，但无济于事。任何帮助，将不胜感激。

这似乎返回了一个值

tell application "Safari"
    tell document 1
    set theVar to (do JavaScript "
var a = document.getElementById('unitsdiv').getElementsByClassName('even');
var b = []; 
for (var i = 0; i < a.length; i++) 
{ b[i] = a[i].textContent; };
console.log(b.length);
console.log(b[1]); 
console.log(b[0]);
b[0];")
end tell
end tell
log theVar

如果我尝试从javascript代码末尾的[0]处取出数组选择器b，请告诉AppleScript log theVar它会抛出错误theVar没有定义。

为什么我的JavaScript不将数组返回到AppleScript列表？
