Pada masa lalu, apabila saya ingin menggunakan kawalan kalendar, saya perlu memuat turun satu set kod sumber terus dari Internet, saya sentiasa mempunyai idea bahawa saya ingin menulis kawalan kalendar sendiri. Saya hanya berminat dan masa dibenarkan, jadi saya meneroka sendiri saya menulis satu, fungsinya cukup lengkap, dan antara mukanya baik-baik saja. Mungkin perkara yang paling penting adalah untuk memaparkan butang di sebelah kanan kawalan input Saya terus menambah latar belakang pada input dan kemudian mengalih keluar sempadan input.

Ini adalah versi pertama, dan saya merancang untuk membuat versi JavaScript tulen pada masa hadapan, dan saya merancang untuk menggunakan JQuery untuk membuatnya pada masa hadapan.
