Question

我有一个标准的HTML表，但是我似乎找不到任何东西来立足并开始使用。我的桌子是这样的：

    <div id="seriesDiv" style="margin-top: 0px;">
          <table class="tableFile2" summary="Results">
             <tbody><tr>
                <th scope="col" width="7%">Filings</th>
                <th scope="col" width="10%">Format</th>
                <th scope="col">Description</th>
                <th scope="col" width="10%">Filing Date</th>
                <th scope="col" width="15%">File/Film Number</th>
             </tr>
    <tr>
    <td nowrap="nowrap">4</td>
    <td nowrap="nowrap"><a href="/Archives/edgar/data/1087294/000120919119051031/0001209191-19-051031-index.htm" id="documentsbutton">&nbsp;Documents</a></td>
    <td class="small">Statement of changes in beneficial ownership of securities<br>Acc-no: 0001209191-19-051031 Size: 9 KB            </td>
                <td>2019-09-27</td>
             <td></td>
             </tr>
    <tr class="blueRow">
    <td nowrap="nowrap">4</td>
    <td nowrap="nowrap"><a href="/Archives/edgar/data/1087294/000120919119050363/0001209191-19-050363-index.htm" id="documentsbutton">&nbsp;Documents</a></td>
    <td class="small">Statement of changes in beneficial ownership of securities<br>Acc-no: 0001209191-19-050363 Size: 50 KB            </td>
                <td>2019-09-20</td>
             <td></td>
             </tr>

那么标准的东西-表格，表体，trs和tds

我尝试过

var rows = $("#seriesDiv").find("table");
console.log("in front loop ", rows.length);
for (var i = 0; rows.length; i++) {
    console.log("inside loop");
}

我尝试过：

var rows = $(".tableFile2").find("tr");
```

Can someone please show me how to do this?  I want to loop through TRs, and for each TR, I want to loop through TDs.

thank you

Answer 1

下面的代码将帮助您遍历每个tr。另外，请注意，如果只为每个“ tr”寻找“ tds”，则不会找到“ th”。因此，您还必须寻找“ ths”。请注意，以下代码仅是示例。因此，没有错误检查或数据评估之类的东西。
