I have this table, that I cannot modify, how can I store the numbers from those two rows into two arrays with jQuery ?

Answer 1

This will only work if you want the numbers from the last two rows in a three row table –

var arrone = [];
var arrtwo = [];

$("table tr").each(function(i) {
    $(this).find('td.unit-item').each(function() {
        i == 1 ? arrone.push($.trim($(this).text())) : arrtwo.push($.trim($(this).text()));
    })
})

console.log(arrone.join(','));
console.log(arrtwo.join(','));

Here’s a slightly terser example using map –

var arrone = $("table tr:nth-child(2)").find('td.unit-item').map(function() {
    return $.trim($(this).text())
});

var arrtwo = $("table tr:nth-child(3)").find('td.unit-item').map(function() {
    return $.trim($(this).text())
});

console.log(arrone.get().join(','));
console.log(arrtwo.get().join(','));
