将类应用于 DOM 中的父元素？

        <li id="weather" class="widget-container widget-dark-blue">
            <h3 class="widget-title">Weather</h3>
            <?php include (TEMPLATEPATH . '/widgets/weather.php'); ?>
        </li>

Weather.php 向天气服务发出一个curl 请求并返回一个表。使用 DomDocument 类，我读取了 td 内部的值。我将当前天气状况的类名应用于 div.weather。

<?php

require_once('classes/SmartDOMDocument.class.php');

$url = 'some/domain...';

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);

$str = curl_exec($curl);

$dom = new SmartDOMDocument();
$dom->loadHTML($str);
$xpath = new DOMXPath($dom);

$tds = $xpath->query('//div/table/tr/td');

foreach ($tds as $key => $cell) {
    if ($key==1) {
        $condition = $cell->textContent;
        //$cell->parentNode->setAttribute('class', 'hello');
        echo "<div class='weather " . strtolower($condition) ."'>";
        ...

？>

一切正常。我唯一的问题是，是否有一种 PHP 方法可以将类名 $condition 应用于保存信息的列表项？因此，我不想在 li#weather 中使用 $condtion 类，而是希望在类中使用 li#weather 。

有什么方法可以将 $condition 类应用到包含所有内容的列表中。我可以用 javascript/jquery 轻松做到这一点。不过我想知道是否有一些服务器端解决方案。

谢谢

        </li>

weather.php does a curl request to a weather service and returns a table. With the DomDocument Class I read the values inside of the td's. I'm applying a classname of the current weather condition to a div.weather.

<?php

require_once('classes/SmartDOMDocument.class.php');

$url = 'some/domain...';

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);

$str = curl_exec($curl);

$dom = new SmartDOMDocument();
$dom->loadHTML($str);
$xpath = new DOMXPath($dom);

$tds = $xpath->query('//div/table/tr/td');

foreach ($tds as $key => $cell) {
    if ($key==1) {
        $condition = $cell->textContent;
        //$cell->parentNode->setAttribute('class', 'hello');
        echo "<div class='weather " . strtolower($condition) ."'>";
        ...

Everything works fine. My one and only question is, is there a PHP way of applying the classname $condition to the list-item that holds the information?
So instead of having a class with the $condtion inside of my li#weather I'd like to have the li#weather the class.

<li id="weather" class="widget-container widget-dark-blue $condition">

Is there any way I can apply the $condition class to the list that hold's everything. I could easily do it with javascript/jquery. However I wonder if there is some serverside solution.

thank you

也许你可以尝试这样的事情：

$parent = $cell->parentNode;

while ($parent->tagName != 'li')
{
    $parent = $parent->parentNode;
}

$class = $parent->getAttribute('class');
$parent->setAttribute('class', $class . ' ' . strtolower($condition));

Maybe you could try somthing like :

$parent = $cell->parentNode;

while ($parent->tagName != 'li')
{
    $parent = $parent->parentNode;
}

$class = $parent->getAttribute('class');
$parent->setAttribute('class', $class . ' ' . strtolower($condition));
