How to show and hide a simple <ol> list with onclick?

Question

Considering the following paragraph and list:

<p id = "list1" onclick = "openList1()">List of Items</p>
<ol>
  <li><a href = "/exampleFolder/file1.txt">List Item 1</a></li>
  <li><a href = "/exampleFolder/file2.txt">List Item 2</a></li>
  <li><a href = "/exampleFolder/file3.txt">List Item 3</a></li>
  <li><a href = "/exampleFolder/file4.txt">List Item 4</a></li>
  <li><a href = "/exampleFolder/file5.txt">List Item 5</a></li>
</ol>

How can I show and hide this entire list with Javascript?

<script>
function openList1() {
...
}
</script>

I thank you for the attention!

Answer 1

You can give an id to the OL list.

<p id = "list1" onclick = "openList1()">List of Items</p>
<ol id="ollist">
  <li><a href = "/exampleFolder/file1.txt">List Item 1</a></li>
  <li><a href = "/exampleFolder/file2.txt">List Item 2</a></li>
  <li><a href = "/exampleFolder/file3.txt">List Item 3</a></li>
  <li><a href = "/exampleFolder/file4.txt">List Item 4</a></li>
  <li><a href = "/exampleFolder/file5.txt">List Item 5</a></li>
</ol>

And then in your javascript you can toggle it like this...

<script>
function openList1() {
    var list = document.getElementById("ollist");

    if (list.style.display == "none"){
        list.style.display = "block";
    }else{
        list.style.display = "none";
    }
}
</script>

Answer 2

var myList = document.getElementsByTagName('ol');
myList[0].style.visibility = 'hidden'; // 'visible'

Answer 3

<script>
function openList1() {
$("ol").toggle();
}
</script>

Can you use JQuery? If so, try the above

Answer 4

First you can modify your list:

<ol id="list" style="display: none;">

You can write a function to show:

function showStuff(id) {
    document.getElementById(id).style.display = 'block';
}
// call function to show your list
showStuff("list");

To hide your element:

function hideStuff(id) {
    document.getElementById(id).style.display = 'none';
}
// call function to hide your list
hideStuff("list");

Answer 5

var ol = document.getElementByTagName('ol');
 ol.style.display='none';
