Why Doesn't My jQuery Mobile Checkbox Validation Work?

How to Determine if a Checkbox is Checked

In your mobile web application built with jQuery Mobile, you want to check the checked status of a checkbox. However, your code doesn't seem to be working.

You've tried using the following code:

<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>

But it doesn't execute as expected.

The Solution

The reason for this behavior is that checked is a boolean property. Instead of comparing it to 1, you should use it directly in an if condition. Here's the corrected code:

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

This code correctly checks the checked status of the checkbox and displays the appropriate alert message.
