Was adding tab names and class name from the database took care of dots hyphens but couldn't debug please help new to this.
<?PHP
$result = $conn->query("select hyd_name,hyd_classname from hydro_department");
while ($row = $result->fetch_assoc())
{
unset($hmr_id);
$hyd_name = $row['hyd_name'];
$hyd_classname=$row['hyd_classname'];
echo '<button class="tablinks" onclick="openTab(event,"'.$hyd_classname.'")">'.$hyd_name.'</button>';
}
?>
Here is my JS
function openTab(evt, tabName) {
// Declare all variables
var i, tabcontent, tablinks;
// Get all elements with class="tabcontent" and hide them
tabcontent = document.getElementsByClassName("tabcontent");
for (i = 0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
// Get all elements with class="tablinks" and remove the class "active"
tablinks = document.getElementsByClassName("tablinks");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].className = tablinks[i].className.replace(" active", "");
}
// Show the current tab, and add an "active" class to the button that opened the tab
document.getElementById(tabName).style.display = "block";
evt.currentTarget.className += " active";
}
