I am receiving an undefined value when using document.getElementsByClassName

<canvas id="can" height="500px" width="1200px"></canvas>
<div class="name">
    <h1>LEONARDO</h1> </div>
<script>
    var name=['WATSON','LEONARDO',"SMITH","EMILY"]
    var counter=0
    var data=document.getElementsByClassName("name")[0].value;
    console.log(data);

undefined is displayed on the console.

Answer №1

The issue likely lies within .value

If you were to only display

document.getElementsByClassName("name")[0]
, you would see the inner HTML for your div - value is typically used for inputs.

To retrieve the contents, consider using .innerHTML, .innerText, or .textContent.

Answer №2

In order to achieve the desired outcome, you can utilize the following method by using document.getElementsByTagName("h1") and innerHTML

<canvas id="can" height="500px" width="1200px"></canvas>
<div class="name">
    <h1>AISHWARYA</h1> </div>
<script>
var name=['MOHITE','AISHWARYA',"CHANDRAKANT","KAVITA"]
var counter=0
var data=document.getElementsByTagName("h1")[0].innerHTML;
console.log(data)
</script>
