javascript - jquery获取上面div中select的值

Question

我有以下 HTML 表单。我正在尝试获取 .plotNumber 的值选择 sub_category 的值 field 。

注意:用户可以向表单添加新行，因此可能有多个 <div class="standard-row add-admin-row input-row"> block .

到目前为止，我的代码(有效)除了 plot和category是:

$('.wrapper').on('input', '.inp-calculate', function(e) 
{
    var input       = $(this);
    //var plot      = input.val(); // get plot id
    //var category  = input.val(); // get category id
    var units       = input.val(); // get units

    $.post('checkUnits.php', {
        plot_id:        plot,
        category_id:    category,
        units:          units
    }, function(data) {
        var data = $.parseJSON(data);

        if(data[0] !== true) {
            alert(data);
            input.focus();
            input.val('');
        }
    });
});

我尝试过以下解决方案，但不起作用:

$(this).parent().siblings().find('.plotNumber').val();

HTML 代码:

有人可以帮忙找到解决方案吗？

Answer 1

您没有使用 .parent() 在 DOM 上遍历得足够远因为选择包含在 <div> 中以上三级.inp-calculate 。怎么样:

$(this).closest('fieldset').find('.plotNumber').val();
