how to disable textbox depending up on checkbox checked

Question

hi can any one please tell me how to disable textbox, if checkbox is checked and enable textbox if the checkbox is not checked

Answer 1

Are you using "plain" JavaScript or some library (jQuery, prototype, ...)?

Answer 2

Put this in the checkbox:

onclick="document.getElementById('IdOfTheTextbox').disabled=this.checked;"

Answer 3

Is pseudocode (not a lot of javascript experience):

OnCheckboxChanged(bool isChecked) {
    textbox.Enabled = !isChecked;
}

Answer 4

function disableControl(controlId)
{
    document.getElementById(controlId).disabled = true;
}

Answer 5

Using jQuery:

$("#checkbox").click(function(){
  $("#textbox").disabled = $(this).is(":checked");
});

Answer 6

    <input type="text" id="textBox">
    <input type="checkbox" id="checkBox" onclick="enableDisable(this.checked, 'textBox')">
    <script language="javascript">
    function enableDisable(bEnable, textBoxID)
    {
         document.getElementById(textBoxID).disabled = !bEnable
    }
</script>
