 Cara kedua :

Langkah-langkahnya masih sama seperti cara pertama namun kodenya yang berbeda :

this.state.shouldvisible=(scrolltop>=this.setting.startline)? true : false
if (this.state.shouldvisible && !this.state.isvisible){

this.state.isvisible=true

.click(function(){mainobj.scrollup(); return false})

}
scrolltotop.init()
</script>

Menurut saya cara yang paling simpel dan tidak banyak kode adalah cara yang pertama, tapi ya terserah Anda mau pakai yang mana, toh fungsinya juga sama. Berhubung rasa kantuk sudah tak tertahankan, maka saya sudahi penjelasan membuat tombol back to top di blog ini. Selamat mencoba, pasti berhasil dah.
