I've been working on this nonstop and none of the online suggestions have worked. I have a dynamically created table that refreshes every 5 seconds. There are checkboxes on the table, if you check a box it highlights the row. When the page refreshes all checked states are lost, I need them to be saved, either by local storage or a cookie or even writing out to a file. Please help and thanks in advance.
My currently working code that does not retain the checked state:
<HTML>
<HEAD>
<TITLE>list</TITLE>
<META name="description" content="">
<META name="keywords" content="">
<meta http-equiv="refresh" content="5" >
<style>
.inv {
display: none;
}
table.sortable thead {
background-color:#999;
color:#222222;
font-weight: bold;
cursor: default;
}
table.sortable tbody {
counter-reset: sortabletablescope;
}
table.sortable thead tr::before {
content: "";
display: table-cell;
}
table.sortable tbody tr::before {
content: counter(sortabletablescope);
counter-increment: sortabletablescope;
display: table-cell;
}
</style>
<script src="../../sorttable.js"></script>
<script>
function toggle_highlight(inputTagReference)
{
var is_checked = inputTagReference.checked; //true or false
if(is_checked)
{
inputTagReference.parentNode.parentNode.style.backgroundColor="yellow";
}
else
{
inputTagReference.parentNode.parentNode.style.backgroundColor="";
}
}
</script>
</HEAD>
