I’ve a HTML table that contain several columns. I’ve found a JSscript w3school to sort this table. I’ve slightly modifyed this script to be able to sort also a columns that contain only number. It works well except for 1 column that contain values like this ‘ 548m / 1797ft’ . This kind of value go after higher one?! I really don’t understand what’s going wrong for this particular column.
<TABLE id="table" class="resp">
<thead>
<TR>
<th onclick="sortTable(0)" class="sortable" scope="col"> Position </th>
<th onclick="sortTable(1)" class="sortable" scope="col"> Sommet </th>
<th onclick="sortTable(2)" class="sortable" scope="col"> Altitude </th>
</TR>
</thead>
<tr>
<td data-label="Position"> 1 </td>
<td data-label="Sommet"> Mont Marcy </td>
<td data-label="Altitude"> 1629m / 5343ft </td>
</tr>
<tr>
<td data-label="Position"> 2 </td>
<td data-label="Sommet"> Mont Algonquin </td>
<td data-label="Altitude"> 1559m / 5114ft </td>

</table>
i’ve removed several column as they are not involved in this problem
And the script part
function sortTable(n) {
var table, rows, switching, i, x, y, shouldSwitch, dir, switchcount = 0;
table = document.getElementById("table");
switching = true;
// Set the sorting direction to ascending:
dir = "asc";
/* Make a loop that will continue until
no switching has been done: */
while (switching) {
// Start by saying: no switching is done:
switching = false;
rows = table.rows;
/* Loop through all table rows (except the
first, which contains table headers): */
for (i = 1; i < (rows.length - 1); i++) {
// Start by saying there should be no switching:
shouldSwitch = false;
/* Get the two elements you want to compare,
one from current row and one from the next: */
x = rows[i].getElementsByTagName("TD")[n];
y = rows[i + 1].getElementsByTagName("TD")[n];
/* Check if the two rows should switch place,
based on the direction, asc or desc: */
if (!isNaN(x.innerHTML)) {
// NUMERIC
if (dir == "asc") {
if (Number(x.innerHTML) > Number(y.innerHTML)) {
shouldSwitch = true;
break;
}
} else if (dir == "desc") {
if (Number(x.innerHTML) < Number(y.innerHTML)) {
shouldSwitch = true;
break;
}
}
} else {
// ALPHABETIC
if (dir == "asc") {
if (x.innerHTML.toLowerCase() > y.innerHTML.toLowerCase()) {
// If so, mark as a switch and break the loop:
shouldSwitch = true;
break;
}
} else if (dir == "desc") {
if (x.innerHTML.toLowerCase() < y.innerHTML.toLowerCase()) {
// If so, mark as a switch and break the loop:
shouldSwitch = true;
break;
}
}
}
} // FOR LOOP
if (shouldSwitch) {
/* If a switch has been marked, make the switch
and mark that a switch has been done: */
rows[i].parentNode.insertBefore(rows[i + 1], rows[i]);
switching = true;
// Each time a switch is done, increase this count by 1:
switchcount ++;
} else {
/* If no switching has been done AND the direction is "asc",
set the direction to "desc" and run the while loop again. */
if (switchcount == 0 && dir == "asc") {
dir = "desc";
switching = true;
}
}
}
}
I would think that this particular column would be treated like a string but it seem to not… So i really don’t know waht to do more.
P.S.: SOrry for my bad english, it’s not my language
