แต่พอผมลองเรียก function อีกตัวหนึ่งขึ้นมาเพื่อ หยุดทำสั่ง แต่ไม่ได้ผลช่วยดูที่ครับควรปรับแก้ตรงไหน
คำสั่ง แสดงผลเป็น 0.00 ตามด้วย The time stop แต่พอกด OK ออกไป ทำไมเวลายังกลับมาทำงานต่อจน หมดไปเองครับ
////////
function stop_time()
{
if(document.myform.onClick = true)
{
clearInterval(ct);
document.getElementById("txt").value = "0:00";
alert("The time stop.");
}
}
