If you are wanting them to stay the same when user interacts with them:
如果您希望它们在用户与它们交互时保持不变：
$(function(){
$('#field1').on('keyup blur', function(){
$('#field2').val($(this).val());
}).blur();
});
Triggering the blur() on page load will do the same as code you already have
在页面加载时触发 blur() 与您已有的代码相同
EDITJust realized these are file fields... browser security limits what you can do with them
编辑刚刚意识到这些是文件字段......浏览器安全限制了你可以用它们做什么
