Displayed below is a table containing rows (tr).
I am attempting to reset the background color for all table rows:
for (var i = 0; i < rows.length; i++) {
if (rows[i].hasAttribute("background-color")) {
rows[i].style.backgroundColor = "transparent";
}
}
An example of a row is as follows:
<tr style="background-color: rgb(232, 229, 216);">
To determine if a style is set, check its value and nullify it if true:
const rows = document.querySelectorAll('#demo tbody tr')
for (let row of rows) {
if (row.style.backgroundColor) {
row.style.backgroundColor = null;
}
}<table id="baseline">
<tbody>
<tr style="background-color: red"><td>Foo</td></tr>
<tr style="background-color: blue"><td>Bar</td></tr>
<tr style="background-color: green"><td>Baz</td></tr>
</tbody>
</table>
<table id="demo">
<tbody>
<tr style="background-color: red"><td>Foo</td></tr>
<tr style="background-color: blue"><td>Bar</td></tr>
<tr style="background-color: green"><td>Baz</td></tr>
</tbody>
