使用JavaScript和jQuery进行表排序的问题

标签： javascript jquery html sorting

当我尝试根据第一列中的内容对表格进行排序时，我遇到了问题。我的代码与此ANSWER中的代码几乎相同，但在我的情况下，不幸的是，它不起作用。正如您所看到的那样，运行该代码段表未正确排序。

$('.sort-table').click(function(e) {
    e.preventDefault();                        // prevent default button click behaviour

    var sortAsc = $(this).hasClass('asc'),     // ASC or DESC
        $table  = $('#sort-table'),            // cache the target table DOM element
        $rows   = $('tbody > tr', $table);     // cache all rows from the target table body

    $rows.sort(function(a, b) {

        var keyA = $('td',a).eq(0).text().trim();
        var keyB = $('td',b).eq(0).text().trim();
        
        if (sortAsc) {
            return (keyA > keyB) ? 1 : 0;     // A bigger than B, sorting ascending
        } else {
            return (keyA < keyB) ? 1 : 0;     // B bigger than A, sorting descending
        }
    });

    $rows.each(function(index, row){
      $table.append(row);                    // append rows after sort
    });
});

答案 0 :(得分：2)

您需要添加另一个条件来检查您的排序

    if (sortAsc) {
        // if a > b return 1 / if a < b return -1 / else same so return 0
        return (keyA > keyB) ? 1 : (keyA < keyB) ? -1 : 0;     // A bigger than B, sorting ascending
    } else {
        // if a < b return 1 / if a > b return -1 / else same so return 0
        return (keyA < keyB) ? 1 : (keyA > keyB) ? -1 : 0;     // B bigger than A, sorting descending
    }

此外，无需在最后循环以追加行 - 您可以这样做

$table.find('tbody').append($rows);  // no need to loop through to append

＆＃13;
＆＃13; 
$('.sort-table').click(function(e) {
    e.preventDefault();                        // prevent default button click behaviour

    var sortAsc = $(this).hasClass('asc'),     // ASC or DESC
        $table  = $('#sort-table'),            // cache the target table DOM element
        $rows   = $('tbody > tr', $table);     // cache all rows from the target table body

    $rows.sort(function(a, b) {

        var keyA = $('td',a).eq(0).text().trim();
        var keyB = $('td',b).eq(0).text().trim();
        
        if (sortAsc) {
            return (keyA > keyB) ? 1 : (keyA < keyB) ? -1 : 0;     // A bigger than B, sorting ascending
        } else {
            return (keyA < keyB) ? 1 : (keyA > keyB) ? -1 : 0;     // B bigger than A, sorting descending
        }
    });
    $table.find('tbody').append($rows);  // no need to loop through to append  
});
