https://www.cnblogs.com/Joetao/articles/3583710.html

<div id="dvABC"><br>
  <table class="l_height_30 gridcontent" width="100%" border="0" cellspacing="0" cellpadding="0"><br>
    <thead><br>
      <tr><br>
        <td width="50" class="bg_thead center">序號</td><br>
        <td class="bg_thead pl_10">內容</td><br>
      </tr><br>
    </thead><br>
    <tbody><br>
      <tr><br>
        <td width="50" class="bg_thead center">1</td><br>
        <td class="bg_thead pl_10">aaaaa</td><br>
      </tr><br>
      <tr><br>
        <td width="50" class="bg_thead center">2</td><br>
        <td class="bg_thead pl_10">bbbbb</td><br>
      </tr><br>
      <tr><br>
        <td width="50" class="bg_thead center">3</td><br>
        <td class="bg_thead pl_10">ccccc</td><br>
      </tr><br>
    </tbody><br>
  </table><br>
</div>

<br>
$("#dvABC tr").each( function(){  <br>
  alert( $(this).text() )<br>
 }  )<br>

<br>
var tr = $("#dvABC table tr");<br>
$("#dvABC table tr").each(function() {<br>
    // tr迴圈<br>
    // 如果要TD迴圈，可以像下面這樣寫<br>
    $(this).find("td").each(function() {<br>
        // td邏輯<br>
    });<br>
    // 如果想獲取某一個td的，可以這樣寫<br>
    var td = $(this).find("td:eq(" + tdIdx + ")");<br>
    // 例如獲取第一個單元格$(this).find("td:eq(0)");<br>
