代码：
import execjs# 直接执行
print(execjs.eval('"abc aaa bbb".split(" ")'))# 编译后调用
js_code = """
var t1="aaaa"
function add1(x, y) {return x + y;
}
"""
ctx = execjs.compile(js_code)
print(ctx.call("add1", 1, 2)) # 输出: 3
print(ctx.eval('t1'))执行
['abc', 'aaa', 'bbb']
3
aaaa四，执行文件中的js代码:
text.js
var t=666
function add(a, b) {return a+b
}python
import execjs# 读取js文件
def read_js_file(file_path):with open(file_path, 'r', encoding='utf-8') as f:return f.read()js_code2 = read_js_file('text.js') # 假设norm.js中定义了add函数
print(js_code2) # 查看js代码
ctx = execjs.compile(js_code2)
print(ctx.call("add", 2, 3)) # 输出: 5
print(ctx.eval('t')) # 输出: 666运行:
var t=666
function add(a, b) {return a+b
}5
666
