不同的js文件在同一个HTML中，为什么save_ss()会报错，无法调用
<!DOCTYPE html>
<html lang="en">

script.js
const message = 'Hello world' // Try edit me
// Update header text
document.querySelector('#header').innerHTML = message
// Log to console
console.log(message)
var is_agent
is_agent = 2
function myFunction(){
save_ss()
}
script1.js
function save_ss(){
const zzzz = "GoGoGo"
document.querySelector('#header').innerHTML = zzzz
console.log("haha",is_agent);
};
