Few days ago I had a plan to make a alarm clock in Oracle Apex. So I tried to find out something to do it. And finally did it using HTML,CSS, JavaScript. I feel it works very well. So I am going to share my tricks and code to you. You can try or use it if needed. Even you may customize it your self according to your requirement. Follow below steps.
Step 1. Create a new page and a region using static content type.
<style>
/* (A) FONT */
#ctime, #tpick {
font-family: Impact, sans-serif;
}
.header {
text-align: center;
font-weight: normal;
margin: 5px 0 10px 0;
}
/* (B) CURRENT TIME */
#ctime {
margin: 0 auto;
max-width: 350px;
padding: 10px;
background: #000;
text-align: center;
}
#ctime .header {
color: #c61d1d;
}
#ctime .square {
display: inline-block;
padding: 10px;
margin: 5px;
}
#ctime .digits {
font-size: 24px;
background: #fff;
color: #000;
padding: 20px 10px;
border-radius: 5px;
}
#ctime .text {
margin-top: 10px;
color: #ddd;
}
/* (C) TIME PICKER */
#tpick {
margin: 0 auto;
max-width: 350px;
padding: 10px;
background: #f2f2f2;
white-space: nowrap;
}
#tpick-h, #tpick-m, #tpick-s {
display: inline-block;
width: 32%;
}
#tpick select {
box-sizing: padding-box;
width: 100%;
font-size: 1.2em;
font-weight: bold;
margin: 20px 0;
}
#tset, #treset {
box-sizing: padding-box;
width: 50%;
background: #3368b2;
color: #fff;
padding: 10px;
border: 0;
cursor: pointer;
}
#tset:disabled, #treset:disabled {
background: #aaa;
color: #888;
}
</style>
<script>
var ac = {
// (A) INITIALIZE ALARM CLOCK
init : function () {
// (A1) GET THE CURRENT TIME - HOUR, MIN, SECONDS
ac.chr = document.getElementById("chr");
ac.cmin = document.getElementById("cmin");
ac.csec = document.getElementById("csec");
// (A2) CREATE TIME PICKER - HR, MIN, SEC
ac.thr = ac.createSel(23);
document.getElementById("tpick-h").appendChild(ac.thr);
ac.thm = ac.createSel(59);
document.getElementById("tpick-m").appendChild(ac.thm);
ac.ths = ac.createSel(59);
document.getElementById("tpick-s").appendChild(ac.ths);
// (A3) CREATE TIME PICKER - SET, RESET
ac.tset = document.getElementById("tset");
ac.tset.addEventListener("click", ac.set);
ac.treset = document.getElementById("treset");
ac.treset.addEventListener("click", ac.reset);
// (A4) GET ALARM SOUND
ac.sound = document.getElementById("alarm-sound");
// (A5) START THE CLOCK
ac.alarm = null;
setInterval(ac.tick, 1000);
},
// (B) SUPPORT FUNCTION - CREATE SELECTOR FOR HR, MIN, SEC
createSel : function (max) {
var selector = document.createElement("select");
for (var i=0; i<=max; i++) {
var opt = document.createElement("option");
i = ac.padzero(i);
opt.value = i;
opt.innerHTML = i;
selector.appendChild(opt);
}
return selector
},
// (C) SUPPORT FUNCTION - PREPEND HR, MIN, SEC WITH 0 (IF < 10)
padzero : function (num) {
if (num < 10) { num = "0" + num; }
else { num = num.toString(); }
return num;
},
// (D) UPDATE CURRENT TIME
tick : function () {
// (D1) CURRENT TIME
var now = new Date();
var hr = ac.padzero(now.getHours());
var min = ac.padzero(now.getMinutes());
var sec = ac.padzero(now.getSeconds());
// (D2) UPDATE HTML CLOCK
ac.chr.innerHTML = hr;
ac.cmin.innerHTML = min;
ac.csec.innerHTML = sec;
// (D3) CHECK AND SOUND ALARM
if (ac.alarm != null) {
now = hr + min + sec;
if (now == ac.alarm) {
if (ac.sound.paused) { ac.sound.play(); }
}
}
},
// (E) SET ALARM
set : function () {
ac.alarm = ac.thr.value + ac.thm.value + ac.ths.value;
ac.thr.disabled = true;
ac.thm.disabled = true;
ac.ths.disabled = true;
ac.tset.disabled = true;
ac.treset.disabled = false;
},
// (F) RESET ALARM
reset : function () {
if (!ac.sound.paused) { ac.sound.pause(); }
ac.alarm = null;
ac.thr.disabled = false;
ac.thm.disabled = false;
ac.ths.disabled = false;
ac.tset.disabled = false;
ac.treset.disabled = true;
}
};
// (G) START CLOCK ON PAGE LOAD
window.addEventListener("load", ac.init);
</script>
Step 3. Copy-Paste this code into Page properties >> Region>> Source
<!-- (A) CURRENT TIME -->
<div id="ctime">
<h1 class="header">THE CURRENT TIME</h1>
<div class="square">
<div class="digits" id="chr">00</div>
<div class="text">HR</div>
</div>
<div class="square">
<div class="digits" id="cmin">00</div>
<div class="text">MIN</div>
</div>
<div class="square">
<div class="digits" id="csec">00</div>
<div class="text">SEC</div>
</div>
</div>
<!-- (B) SET ALARM -->
<div id="tpick">
<h1 class="header">
SET ALARM
</h1>
<div id="tpick-h"></div>
<div id="tpick-m"></div>
<div id="tpick-s"></div>
<div>
<input type="button" value="Set" id="tset"/>
<input type="button" value="Reset" id="treset" disabled/>
</div>
</div>
<!-- (C) ALARM SOUND -->
<audio id="alarm-sound" loop>
<source src="#APP_IMAGES#Arekbar.mp3" type="audio/mp3">
</audio>
Step 4. Upload a ringtone in
Shared ComponentsStatic Application Files then copy the reference for use as your ringtone source.
Step 5. Change the music directory source form Step 3 code. Use here new directory of your ringtone.
