我有以下div

<table>
<tbody>
   <tr >
      <td class="dvd_brdb">
         <p class="PL10">
            <a href="fdsf" class="bl_12"><b>APM Industries</b></a>
         </p>
      </td>
      <td class="dvd_brdb">
         <p class="PL30"><span>06-Nov-2015</span></p>
      </td>
      <td class="dvd_brdb">
         <p class="PR20 FR">52.50</p>
      </td>
      <td class="dvd_brdb">
         <p class="PR15 FR  r_12">-0.94</p>
      </td>
      <td class="dvd_brdb">
         <p class="PR15 FR">59.90</p>
      </td>
      <td class="dvd_brdb">
         <p class="PR15 FR">32.55</p>
      </td>
   </tr>
   <tr bgcolor="#f6f6f6">
      <td class="dvd_brdb">
         <p class="PL10">
            <a href="jhg" class="bl_12"><b>Apollo Tyres</b></a>
         </p>
      </td>
      <td class="dvd_brdb">
         <p class="PL30"><span>30-Oct-2015</span></p>
      </td>
      <td class="dvd_brdb">
         <p class="PR20 FR">190.95</p>
      </td>
      <td class="dvd_brdb">
         <p class="PR15 FR  gr_12">0.24</p>
      </td>
      <td class="dvd_brdb">
         <p class="PR15 FR">249.45</p>
      </td>
      <td class="dvd_brdb">
         <p class="PR15 FR">154.70</p>
      </td>
   </tr>
</tbody>
</table>

我正在尝试以Company Name和Date这样的方式阅读

$("tbody tr").each(function(){
    var company_name = $(this).find("td").find(".PL10").find(".bl_12").text();
    var date_res = $(this).find("td:eq(2)").find(".dvd_brdb").find(".PL30").text();
    console.log(company_name);
    console.log(date_res);
});

我可以获得company name，但在获取date方面遇到问题。

这个选择器可以。

Answer 2

当你这样做时

$(this).find("td:eq(2)")

结果已经td.dvd_brdb。

所以，只需从.find(".dvd_brdb")移除$(this).find("td:eq(2)").find(".dvd_brdb").find(".PL30").text();即可。

我更新您的代码，如下所示。

$("tbody tr").each(function(){

    var company_name = $(this).find("td").find(".PL10").find(".bl_12").text();

    var date_res = $(this).find("td:eq(1)").text();
    console.log(company_name);
    console.log(date_res);

});

你可以尝试

Enumeration enumeration = NetworkInterface.getNetworkInterfaces();

NetworkInterface eth0 = null;

while (enumeration.hasMoreElements() {

eth0 = enumeration.nextElement()
if (eth0.getName().equals("eth0")) {

    //there is probably a better way to find ethernet interface
    break;
}

}

InetAddress group = InetAddress.getByName(IP);

MulticastSocket s = new MulticastSocket(PORT);

s.setSoTimeout(10000);

//s.joinGroup(group);
 //this will throw "No such device" exception

s.joinGroup(new InetSocketAddress(group, PORT), eth0);

// this works just fine

for (int i = 0; i < 10; ++i) {

byte[] buf = new byte[8096];

DatagramPacket recv = new DatagramPacket(buf, buf.length);

s.receive(recv);

System.out.println("Recieved " + recv.getLength() + " bytes.");

}

s.leaveGroup(group);
