Why is my jQuery Mobile checkbox validation code failing?

How to Determine Checkbox Selection Status

Problem

You have written code in jQuery Mobile to validate if a checkbox is checked. Despite your efforts, the code fails to execute.

<script type="text/javascript">
  function validate(){
    if (remember.checked == 1){
      alert("checked") ;
    } else {
      alert("You didn't check it! Let me check it for you.")
    }
  }
</script>

<input>

Solution

The problem arises from incorrect comparison of the checked property. Instead of comparing it to 1, use the boolean property directly:

function validate(){
    var remember = document.getElementById('remember');
    if (remember.checked){
        alert("checked") ;
    }else{
        alert("You didn't check it! Let me check it for you.")
    }
}
