I have this
<div id="chart1" class="bar-chart secondary" data-total="42" animated>
<span class="bar-chart--inner" style="width:42%;"></span>
<span class="bar-chart--text">42% </span>
</div>
and I have one javascript variable var score that I need to assign to data-total="42"and <span class="bar-chart--text">42% </span>
My intention is to replace 42 with my javascript variable. I have tried this
document.getElementById("chart1").innerHTML =score that I have found from this forum but did not work. Please help.
<div id="chart1" class="bar-chart secondary" data-total="document.getElementById("chart1").innerHTML =score" animated>
<span class="bar-chart--inner" style="width:42%;"></span>
<span class="bar-chart--text">42% </span>
</div>
https://developer.mozilla.org/en-US/docs/Learn/HTML/Howto/Use_data_attributes
get the element in a JS script
then set elem.dataset.total
document.getElementById("chart1").dataset.total = score
<body>
<div id="chart1" class="bar-chart secondary" data-total="42" animated>
<span class="bar-chart--inner" style="width:42%;"></span>
<span class="bar-chart--text">42% </span>
</div>
<script type="text/javascript">
var score = 20
document.getElementById("chart1").dataset.total = score
</script>
</body>
For setting the html of an element, you can use innerHTML, just need to select that element in another lookup.
document.querySelector(".bar-chart--text").innerHTML = score
