如何更改background-color中元素的<iframe>？ <iframe>位于我的域中。这是完整的代码（HTML，PHP和jQuery）：

<?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);  
} 

?>

        }

        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) {

          do {

              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;

Answer 1

$("#id_of_element").css("backgroundColor","green");

使用css：

#id_of_element:hover {
    backgroundColor: green
}
