You can do it like this:

HTML

<input type="checkbox" id="Check" ></input>
<input type="checkbox" id="Check1">
</input>

In JavaScript:

JavaScript

function function1(){
  document.getElementById("Check1").checked = true;
}

@Sanket Thanks for Formatting, but you missed the onclick() event.

Try this:

XML

<!DOCTYPE html>
<html>
<head>
<script>
function myfunction()
{
    document.getElementById('checkbox2').checked = document.getElementById('checkbox1').checked
}
</script>
</head>
<body>
<input type="checkbox" id="checkbox1" onclick="myfunction();">Checkbox1
<input type="checkbox" id="checkbox2">Checkbox2
</body>
</html>

how to dynamically store id in one checkbox

Peter Leow 14-Jan-15 2:45am

I do not get you. Store id of a checkbox in another checkbox? Where of the other checkbox? An id is supposed to be unique throughout a web document. Furthermore, the checkbox is not meant for storage purpose. Are you trying to achieve something?
