Question

我有两个代码，我尝试以某种方式连接这两个代码。在代码中也是获取xpath位置的函数，但是如何在iframe上使用它。 $(#iframeID) ....并将getXpath函数的结果写入焦点字段。首先我加载一些URL我尝试使用getXpath位置函数并将结果写入焦点的字段但不起作用。

以下是我用来获取内容的一些代码，并在我的域名中显示iframe的代码（因此我可以获取XPath因为iframe在我的域中），然后使用getXpath函数将结果写入焦点领域：

<?php 

error_reporting(E_ALL ^ E_NOTICE); 

$url = $_GET['url']; 

if( ! empty($url)) 
{ 
    $data = file_get_contents($url); 

    $data = str_replace('<head>', '<head><base href="'.$url.'" /></base>', $data); 

    $data = preg_replace('#<script(.*?)>(.*?)</script>#is', '', $data); 
    $data = preg_replace('#<iframe(.*?)></iframe>#is', '', $data); 

    $data .=  
    ' 
    <script src="http://code.jquery.com/jquery-latest.js"></script> 
    <script> 
    $("div").each(function(i){ 
        if($(this).css("position") == "fixed") $(this).css("display", "none"); 
    }); 
    </script> 
    ' 
    ; 

    die($data);  
} 

?>

这是HTML / JavaScript：

        }

        if(node.previousSibling) {
          var count = 1;
          var sibling = node.previousSibling
          do {
            if(sibling.nodeType == 1 && sibling.nodeName == node.nodeName) {count++;}
            sibling = sibling.previousSibling;
          } while(sibling);
          if(count == 1) {count = null;}
        } else if(node.nextSibling) {
          var sibling = node.nextSibling;
          do {
            if(sibling.nodeType == 1 && sibling.nodeName == node.nodeName) {
              var count = 1;
              sibling = null;
            } else {
              var count = null;
              sibling = sibling.previousSibling;
            }
          } while(sibling);
        }

        if(node.nodeType == 1) {
          path.push(node.nodeName.toLowerCase() + (node.id ? "[@id='"+node.id+"']" : count > 0 ? "["+count+"]" : ''));
        }
        return path;
      };
