如何控制<a>标签ID</a>后面的<a>代码中的</a>查找<a>ID是动态生成的？</a>

Question

我正在尝试访问<a>标记ID，以使用它动态生成的ID。

DataTable dtt = getrecord("select Seen from mytable where tableid='" + id + "' ");
if (dtt.Rows[0]["Seen"].ToString() == "No")
{
       str += "<a style=\"background-color: #f5f5f5;border:1px solid\" title=\"View Alert\" aria-controls=\"collapseactswild\" aria-expanded=\"false\" href=\"#collapseactswild" + i + "\" data-parent=\"#accordionactswild\" data-toggle=\"collapse\" id=\"headingactswild" + i + "\" role=\"tab\" class=\"panel-heading collapsed\"><span > ( " + (i + 1) + " ) </span><span class=\"panel-title\">" + dt.Rows[i]["Agency_Name"].ToString() + "</span> </a>";
}
