How do I add a list element to an existing ul using a function from an onclick? I need it to add to this type of list ...
<ul id="list">
<li id="element1">One</li>
<li id="element2">Two</li>
<li id="element3">Three</li>
</ul>
... another list item with the id "element4" and text "Four" under that. I tried this function but it doesn't work...
function function1() {
var ul = document.getElementById("list");
var li = document.createElement("li");
li.appendChild(document.createTextNode("Element 4"));
}
I don't know JQuery so Javascript only please. Thank you!!

You were almost there:
You just need to append the li
to ul
and voila!
So just add
ul.appendChild(li);
to the end of your function so the end function will be like this:
function function1() {
var ul = document.getElementById("list");
var li = document.createElement("li");
li.appendChild(document.createTextNode("Element 4"));
ul.appendChild(li);
}
There is nothing much to add to your code except appending the li tag to the ul
ul.appendChild(li)
and there you go just add this to your function and then it should work.
First you have to create a li
(with id and value as you required) then add it to your ul
.
Javascript ::
addAnother = function() {
var ul = document.getElementById("list");
var li = document.createElement("li");
var children = ul.children.length + 1
li.setAttribute("id", "element"+children)
li.appendChild(document.createTextNode("Element "+children));
ul.appendChild(li)
}
Check this example that add li
element to ul
.
