是否可以将列添加到现有表中,如下所示:

<table id="tutorial" width="600" border="0">
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
</table>

用js？

他们可以选择在php变量中保存curl请求的outpout吗？

因为如果我只保存$ result,我会得到1或者没有

<?php
$url='http://icanhazip.com';
$proxy=file ('proxy.txt');
$useragent='Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)';

for($x=0;$x<count($proxy);$x++)
{
$ch = curl_init();
//you might need to set some cookie details up (depending on the site)
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
curl_setopt($ch, CURLOPT_URL,$url); //set the url we want to use
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, $proxy[$x]);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent); //set our user agent
$result= curl_exec ($ch); //execute and get the results
print $result; //display the reuslt
$datenbank = "proxy_work.txt"; 
$datei = fopen($datenbank,"a");
fwrite($datei, $result);  
fwrite ($datei,"\r\n"); …

如果单击"提交"按钮,输入字段的值为空,如何使用JQUERY显示警报？

<input type="text" id="myMessage" name="shoutbox_msg" size="16" class="field_nosize" maxlength="150">&nbsp;
<input id="submit" type="submit" name="submit_post" class="button_nosize" value="Senden" onclick="sendMessage(); clearInput();">

我尝试了使用Flex框的新html设计。Chrome 58版本58.0.3029.110中的设计正确，但IE11中不正确。我没有尝试其他浏览器。

有什么问题

body {
  display: flex;
  flex-flow: row wrap;
}

#left {
  flex: 6 0%;
  display: flex;
  flex-flow: row wrap;
}

#right {
  flex: 1 0%;
  background-color: black;
}

#top {
  flex: 1 100%;
  background-color: red;
}

#nav {
  flex: 1 0%;
  background-color: green;
}

#main {
  flex: 6 0%;
  background-color: blue;
}

#notepad {
  flex: 1 0%;
  background-color: yellow;
}

#chat {
  flex: 6 0%;
  background-color: orange;
}

#break {
  flex: 1 100%;
}

<div id="left">
  <div id="top">test</div> …
