PHP的HTML DOM解析 - 找不到元素附加的JavaScript [英] PHP HTML DOM Parse - Can't find element appended javascript

问题描述

我正在尝试从网站获取元素。但我找不到元素附加的JavaScript。解决这个问题>
代码在这里：

  $ dom = new Dom; 
 $ obj = $ dom-> loadFromUrl（$ url）; 
 $ element = $ obj-> find（.c-payment）; 
 echo count（$ element）; 
  

结果= 0，但它在网站上

您可以尝试使用 V8 Javascript引擎集成。但我认为你不能轻易达到你想要的。

解决方案

When you reading a web page content with PHP, you are getting only static content (which are providen from a web server). The dinamic part of the content (which will be generated by JavaScript) do not exists at that moment, because PHP do not executes the JavaScript code. You can try to use V8 Javascript Engine Integration. But I do not think that you easily can achieve what you want. Maybe it will be useful for you: https://github.com/scraperlab/browserext
