节点当前在严格模式下启用类构造。
如果我有以下课程：
$attendance = "2015-11-18 08:48:23";
$check_in = "08:00:00";
if ( strlen($check_in) <= 8 ) { // Does not include date. Prepend it automatically:
$parts = explode(" ",$attendance);
$attendance_date = $parts[0];
$check_in = "{$attendance_date} {$check_in}";
}
$late = round((strtotime($check_in) - strtotime($attendance))/60,0);
可导出到另一个模块的相应导出语句是什么。另一个文件的import语句怎么样？
答案 0 :(得分：2)
使用commonJS require和module.exports与目前在节点中“导入”或“导出”其他任何内容的方式相同：
Foo.js
class Foo {}
module.exports = Foo
// or if you want to edit additional objects:
// module.exports.Foo = Foo
// module.exports.theNumberThree = 3
Bar.js
var Foo = require("./Foo")
var foo = new Foo()
答案 1 :(得分：1)
这确实是Node支持ES6模块的问题。虽然它目前允许类，但ES6的导入/导出功能尚未实现，并且更多地依赖于CommonJS要求。
要导出，请使用以下内容：
int process_count = atoi(argv[2]);
if ( process_count < 1 )
exit(EXIT_FAILURE); // or similar
int p_id[process_count], io_burst[process_count], priority[process_count], cpu_burst[process_count];
导入：
