Question

我正在删除一个值为（未设置）的对象，并在表中显示剩余的对象。

我可以删除对象但是当我尝试在表格中显示剩余的对象时，会显示所有对象，包括已删除的对象。有人可以看看我做错了吗？

HTML：

<table class="tg" id="adwords_table" border='1'>
    <tr>
        <th class="tg-031e" rowspan="2">Campaign ID</th>
        <th class="tg-yw4l" colspan="5">Acquisition</th>
        <th class="tg-yw4l" colspan="2">Conversions</th>
    </tr>
    <tr>
        <td class="table-parent tg-yw4l">Clicks</td>
        <td class="table-parent tg-yw4l">Cost</td>
        <td class="table-parent tg-yw4l">CPC</td>
        <td class="table-parent tg-yw4l">CTR</td>
        <td class="table-parent tg-yw4l">Impressions</td>
        <td class="table-parent tg-yw4l">Goal Conversion Rate</td>
        <td class="table-parent tg-yw4l">Goal Completions</td>
    </tr>
    <tr>
        <td class="tg-yw4l"></td>
        <td class="tg-yw4l gapiTotalAdClicks"></td>
        <td class="tg-yw4l gapiTotalAdCost">$</td>
        <td class="tg-yw4l gapiTotalAdCPC">$</td>
        <td class="tg-yw4l gapiTotalAdCTR">%</td>
        <td class="tg-yw4l gapiTotalAdImpressions"></td>
        <td class="tg-yw4l gapiTotalAdconversions">%</td>
        <td class="tg-yw4l gapiTotalAdCompletions"></td>
    </tr>

兴趣点在于每一个：＆＃34;如果＆＃34;没有＆＃34;否则＆＃34;部分。正确的是：

        $.each(adw, function (i, val) {
            if (val.campaign == "(not set)") // delete index
            {
                delete adw[i];
                console.log(adw);
            } else {
                var adwordsHTML = ''
                adwordsHTML += '<tr><td class="tg-yw4l">' + val.campaign + '</td><td class="tg-yw4l">' + val.adclicks + '</td><td class="tg-yw4l">$' + val.adcost + '</td><td class="tg-yw4l">$' + (+val.cpc).toFixed(2) + '</td><td class="tg-yw4l">' + (+val.ctr).toFixed(2) + '%</td><td class="tg-yw4l">' + val.impressions + '</td><td class="tg-yw4l">%' + (+val.goalConversionRateAll).toFixed(2) + '</td><td class="tg-yw4l">' + val.goalCompletionsAll + '</td></tr>';
                $('#adwords_table').append(adwordsHTML);
            }
        });
