I am filtering a table and exporting it to excel. To exclude the filtered rows, i have to set the data-exclude="true" in the 'tr'-element
function Search() {
var input, filter, table, tr, td, i, txtValue;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[7];
if (td) {
txtValue = td.textContent || td.innerText;
if (txtValue.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "" ;
//Set here the Code data-exclude="false"
} else {
tr[i].style.display = "none";
//Set here the Code data-exclude="true";
}
}
}
}``
You can update attributes for an element using setAttribute function
tr.setAttribute('data-exclude', true)
You can use getAttribute function to get the value of a specific attribute. Note that value is returned as a string and need to be converted to a boolean value in your case to filter
