Tips for showcasing JavaScript variables on a webpage

I am working with various JavaScript variables that involve displaying values inside div elements.

 goalDiv = "<div class=goal-parent id=goal-parent"+Id+">"+
    "<div class=goal>"+
    "<div class=top-layer>"+
    "<div class=component>"+

    "<select class=component-select>"+
    "<option id=one><span id='source_name'></span></option>"+
    "</select>"+

    "</div>"+
"</div>"+
"</div>"+
"</div>";

Id = "some unique div value";

After inserting this goalDiv into a div, I attempt to update the content within it as shown below:

document.getElementById(Id).innerHTML = goalDiv;
document.getElementById('source_name').innerHTML = "changed value";

While the first innerHTML method is successful, the second one fails. Can anyone point out what mistake I might be making?

Answer №1

It is not recommended to nest span inside option tags. To modify the dropdown options, you can use the following JavaScript code:

document.getElementById('one').innerHTML = "new value";
