私の質問は、画像アイコンが td に存在するかどうかを確認する最良の方法は何ですか? src="../App_Themes/Default/images/phone.gif"/
ここに私のHTMLソースコードがあります
<div id="ctl00_ContentPlaceHolder1_AddControl1_pnlList">
<table id="ctl00_ContentPlaceHolder1_AddControl1_gv">
<tr class="item">
<td align="center"><a href="javascript:__doPostBack('ctl00$Content$AddControl1$gv','Select$2')">Edit</a></td>
<td align="center" style="width: 15px;">
<img id="ctl00_ContentPlaceHolder1_AddControl1_gv_ctl05_imgMobile"
src="../App_Themes/Default/images/mobile.gif"
src="" align="middle" style="border-width: 0px;" />
</td>
<td>Know For Sure</td>
<td> </td>
<td>Abacd</td>
<td>Teachers</td>
<td>
<img src="../App_Themes/Default/images/check.png" alt='Active' style='display: ;' />
</td>
<td>3/2/2011 9:48:00 AM</td>
</tr>
