在PHP之前先加载并显示HTML [英] Load and display HTML first before PHP
问题描述
我有2个php文件（index.php和lelong.php）。我试图先将html加载到index.php（表）中，并在第二列中显示word（计算中...），而lelong.php从网站提取数据后再输出。
I have 2 php files(index.php and lelong.php). I am trying to load the html first in the index.php (table) and display the word(Calculating...) on the second column while the lelong.php extracting the data from the website before outputting them.
有没有办法做到这一点？我听说过使用JS或AJAX，但不确定如何操作。
Is there a way to do that? I heard of using JS or AJAX but not really sure how to do it.
Index.php
Index.php
<!DOCTYPE html>
<html>
<head>
<?php include 'lelong.php'; ?>
</head>
<body>
<table border ="1" style = "width:50%">
<tr>
<td>E-Commerce Website</td>
<td>No. of Products </td>
</tr>
<tr>
<td>Lelong</a></td>
<td><?php echo $lelong; ?></td>
</tr>
</table>
<body>
lelong.php
lelong.php
<?php
$grep = new DoMDocument();
@$grep->loadHTMLFile("http://www.lelong.com.my/Auc/List/BrowseAll.asp");
$finder = new DomXPath($grep);
$class = "CatLevel1";
$nodes = $finder->query("//*[contains(@class, '$class')]");
$total_L = 0;
foreach ($nodes as $node) {
$span = $node->childNodes;
$search = array(0,1,2,3,4,5,6,7,8,9);
$number = str_replace($search, '', $span->item(1)->nodeValue);
$number = preg_replace("/[^0-9]/", '', $span->item(1)->nodeValue);
$total_L += (int) $number;
}
$lelong = number_format( $total_L , 0 , '.' , ',' );
?>
谢谢
推荐答案
假设 lelong.php 已经可以正常工作，是的，您可以使用ajax获得结果：
Assuming lelong.php is already working fine, yes you could use ajax to get the result:
基本示例：
因此在您的HTML中：
So in your HTML:
<table border ="1" style = "width:50%">
<tr>
<td>E-Commerce Website</td>
<td>No. of Products </td>
</tr>
<tr>
<td>Lelong</a></td>
<td class="result_data">Calculating ...</td><!-- initial content. Loading ... -->
</tr>
</table>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
$(document).ready(function(){
// use ajax, call the PHP
$.ajax({
url: 'lelong.php', // path of lelong
success: function(response){
$('.result_data').text(response);
}
})
});
</script>
然后在您的PHP中：
<?php
$grep = new DoMDocument();
@$grep->loadHTMLFile("http://www.lelong.com.my/Auc/List/BrowseAll.asp");
$finder = new DomXPath($grep);
$class = "CatLevel1";
$nodes = $finder->query("//*[contains(@class, '$class')]");
$total_L = 0;
foreach ($nodes as $node) {
$span = $node->childNodes;
$search = array(0,1,2,3,4,5,6,7,8,9);
$number = str_replace($search, '', $span->item(1)->nodeValue);
$number = preg_replace("/[^0-9]/", '', $span->item(1)->nodeValue);
$total_L += (int) $number;
}
$lelong = number_format( $total_L , 0 , '.' , ',' );
echo $lelong; // output lelong
exit;
?>
前面的效果由您控制。您可以为此使用插件。
The effects on the front are yours to control. You could use plugins for that.
