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 have not appended your li
as a child to your ul
element
Try this
function function1() {
var ul = document.getElementById("list");
var li = document.createElement("li");
li.appendChild(document.createTextNode("Four"));
ul.appendChild(li);
}
If you need to set the id , you can do so by
li.setAttribute("id", "element4");
Which turns the function into
function function1() {
var ul = document.getElementById("list");
var li = document.createElement("li");
li.appendChild(document.createTextNode("Four"));
li.setAttribute("id", "element4"); // added line
ul.appendChild(li);
alert(li.id);
}
