<?php
    $ctr = 0;
    while($ctr <= 10){
    ?>
    <td><input required type='text' name='amount[<?echo $ctr; ?>]' class='amount'></td>
    <td><input required type='text' name='mode[<?echo $ctr; ?>]' value='Cash'></td>
    <?php
    $ctr++;
    }
    ?>
    Total Amount: <span class="total_amount">0.00</span>
    Total Cash : <span class="total_cash">0.00</span>
    Total Check: <span class="total_check">0.00</span>

$(document).on('blur','.amount',function () {
    var total = 0;
    var total_cash = 0;
    var total_check = 0;

    $('.amount').each(function () {
        total += parseFloat($(this).val());
    });

    $('.total_amount').html(total);
});

使用上面的代码,我可以得到我在输入量字段中编码的数字的总数。如何获取每个模式、现金(默认)和支票(用户可以将模式更改为支票)的总数?

最佳答案

如果确定下一个输入宽度mode始终对应,则可以使用JQuery.next。因此有必要将每个参数的值检查为NaN。

$(document).on('blur','.amount',function () {
    var total = 0;
    var total_cash = 0;
    var total_check = 0;
    var val, mode;
    $('.amount').each(function () {
        val = parseFloat($(this).val());
        val = val ? val : 0;
        total += val;
        mode = $(this).next().val();
        switch(mode) {
            case "Check" : total_check += val; break;
            case "Cash"  : total_cash  += val; break;
        }
    });

    $('.total_amount').html(total);
    $('.total_cash').html(total_cash);
    $('.total_check').html(total_check);
});
