I pondered for quite some time on how to articulate the issue, but I couldn't. I need assistance in elucidating the code.
My goal is to create a basic JavaScript organizer. The user inputs a task and clicks on the "add to the list" button, which generates a checkbox with a paragraph containing the task text. Additionally, I want the ability to disable the checkbox and strike through the task text when clicked on. I attempted to achieve this by assigning a function (destroyIt()) to each checkbox I create that would disable it upon clicking, but it only seems to work for the last checkbox added. I've been examining this code extensively, but I can't pinpoint what's wrong. Any help would be appreciated. Here is my code:
<html>
<head>
<style id="stil">
.over{
text-decoration:line-through;
}
</style>
<script type="text/javascript">
var numberOfTasks=1;
function insertNew(){
tekst = document.getElementById("zadatak").value;
if(tekst.length>0){
var idEl= "check"+numberOfTasks;
document.getElementById("ispis").innerHTML+="<input type='checkbox' id='check"+numberOfTasks+"'> "+"<span class='"+idEl+"'>"+tekst+"</span> <br/>";
document.getElementById(idEl).onclick= function(){ destroyIt(idEl); };
numberOfTasks++;
}
}
function destroyIt(idEl){
document.getElementById(idEl).disabled=true;
document.getElementById("stil").innerHTML+= "."+idEl+"{text-decoration:line-through;}";
alert(idEl+"{text-decoration:line-through;}");
}
</script>
</head>
<body>
Tasks for: <span id="date"> </span>
<script>
var date= new Date();
document.getElementById("date").innerHTML= ""+ date.getDay() +"." +date.getMonth() +"." +date.getFullYear();
</script>
<br/> <br/>
New task: <input type="text" id="zadatak"> <button onclick="insertNew()"> add to the list </button>
<button onclick="provera()">Provera</button>
<p id="ispis"> </p>
</body>
