JQuery没有抓取HTML数据

我的网页上显示以下HTML表格。

<div class="timecard">
<table class="misc_items timecard_list" border="0" cellpadding="2" cellspacing="0" style="margin:0 auto;">
    <tbody>
        <tr class="display_row odd">
            <td align="left" class="job_code" style="color:#000099">2400-Orchard</td>
            <td align="right">9:47am</td>
            <td align="right">5/19/2014</td>
            <td align="right" class="hrs">01:00</td>
        </tr>
        <tr class="display_even odd">
            <td align="left" class="job_code" style="color:#000099">1500-Emerald</td>
            <td align="right">12:37am</td>
            <td align="right">5/17/2014</td>
            <td align="right" class="hrs">0:30</td>
        </tr>
    </tbody>
</table>
</div>

<div id="total"></div>

然后我有以下jquery脚本,它抓取每个job_code的总时间并将它们相加并显示它们。但是,它似乎没有正常工作。它不会显示HTML表格下面的jQuery语句所添加的总数。

$(document).ready(function () {

var timeString = $(this).next('td.hrs').text();
var components = timeString.split(':');
var seconds = components[1] ? parseInt(components[1], 10) : 0;
var hrs = parseInt(components[0], 10) + seconds / 60;
total += hrs;

var temp = [];
$('.job_code').each(function (index, element) {
    var text = $(this).text();
    temp.push(text);
});

// remove duplicates
var job_code = [];
$.each(temp, function (index, element) {
    if ($.inArray(element, job_code) === -1) job_code.push(element);
});

var sum = {};
$.each(job_code, function (index, element) {
    var total = 0;
    $('.job_code:contains(' + element + ')').each(function (key, value) {
        var timeString = $(this).siblings('td.hrs').text();
        var components = timeString.split(':');
        var seconds = components[1] ? parseInt(components[1], 10) : 0;
        var hrs = parseInt(components[0], 10) + seconds / 60;
        total += hrs;
        sum[index] = {
            'job_code': element,
                'total': total
        };
    });
});

console.log(sum);

$.each(sum, function (index, element) {
    $('#total').append('<p>Total for ' + element.job_code + ': ' + element.total + '</p>');
});

});

非常感谢任何想法。感谢。

除了total未定义之外,请更改:

var timeString = $(this).next('td.hrs').text();

var timeString = $(this).siblings('td.hrs').text();

.next()字面上仅查看下一个元素,td.hrs不是下一个元素。然而,.siblings()将贯穿所有兄弟姐妹。
