I have a input field and on clicking that checkbox it enables and disables the text box.

By default, the box is checked.

I have the following code. Once i uncheck that box, the display is disabled. However, when i check it again, it still remains disabled.

Can someone please tell me where i am doing it wrong.

Any help is appreciated.

Thank you.

What I have tried:

<input type="checkbox" class="show-check" checked value="1" id="DisplayOnClick">

document.getElementById("DisplayOnClick").onclick = function(){
            document.getElementById("myFieldset").style.display = "block";
        } else {       
            document.getElementById("myFieldset").disabled = !this.checked;          

$(function () {

        $("#DisplayOnClick").click(function () {
            if ($(this).is("checked")){
            }else {

1st go to your textbox properties and find “Enabled” and set it to False
Then double click on your checkbox from form or anywhere and then paste this code:

Private Sub CheckBox1_Click()
If CheckBox1=True Then
ElseIf CheckBox2 = False Then
TextBox1.Enabled= False
End If
End Sub

Just using the following worked for me.

document.getElementById("DisplayOnClick").onclick = function(){
 document.getElementById("myFieldset").disabled = !this.checked;
