Menu
I have a table with multiple columns (for this question I only made two columns) and I want the user to be able to search through a column by the index depending on an option that the user can select. I have working code, but in order to change the search option, I had to copy the function for each input.
How can I search by the index? If a user selects an option like (name), then the javascript function will change the index that it is searching to [0]. if the user selects (location), the function will change the index to [1] and search through that column.
Is this possible? Any help would be appreciated.
const searchName = document.getElementById('searchName');
const searchLoc = document.getElementById('searchLoc');
custSelect.addEventListener('click', () => {
if (custSelect.value == 'custname') {
searchName.style.display = 'block';
searchLoc.style.display = 'none';
} else {
searchName.style.display = 'none';
searchLoc.style.display = 'block';
}
});
// Search for customer, or search for location, index will change based on option selected.
function tableSearch(id, index) {
// Declare variables
var filter, input, table, tr, td, i;
input = document.getElementById(id);
filter = input.value.toUpperCase();
table = document.getElementById(id);
tr = table.getElementsByTagName('tr');
// Loop through all table rows, and hide those who don't match the search query
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[0]; // index will change based on option selected.
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}

This should get you on track
var table = document.getElementById('tab'),
col = document.getElementById('col'),
val = document.getElementById('val');
col.max = table.rows[0].cells.length - 1;
function search() {
var regex = new RegExp(val.value || '', 'i');
for (var i = table.rows.length; i-- > 1;) {
if (regex.test(table.rows[i].cells[+col.value].innerHTML)) {
table.rows[i].style.display = 'table-row';
} else
table.rows[i].style.display = 'none';
}
