JavaScript How to find the nearest neighboring elements of an td using jquery? [closed]

For completeness, without jQuery:

var row = cell.parentNode;
var table_body = row.parentNode;
var neighbors = [];

if (cell.cellIndex > 0) {
    neighbors.push(rows.cells[cell.cellIndex - 1]);
}

if (row.rowIndex > 0) {
    neighbors.push(table_body.rows[row.rowIndex - 1].cells[cell.cellIndex]);
}

if (cell.cellIndex < rows.cells.length - 1) {
    neighbors.push(rows.cells[cell.cellIndex + 1]);
}

if (row.rowIndex < table_body.rows.length - 1) {
    neighbors.push(table_body.rows[row.rowIndex + 1].cells[cell.cellIndex]);
}

This doesn't require too much, for the vertical neighbors however you're going to need the index of 5 (which is 1) -- assuming $(this) represents the td which contains 5:

var index  = $(this).index(),
    left   = $(this).prev("td").text(),
    right  = $(this).next("td").text(),
    top    = $(this).closest("tr").prev("tr").find("td:eq(" + index + ")").text(),
    bottom = $(this).closest("tr").next("tr").find("td:eq(" + index + ")").text();
