How can I solve the problem of preventing IE from downloading Excel files?
When you click the export button, AJAX is used to generate an excel file in the background, and you want to directly display the file storage dialog box on the page,
Neither the window. location. href = ''through js, nor the new page submitted through form, nor the output through stream in the background are blocked by IE;
Who can solve this problem?

PHP code

 
 $file_name="test.xls"; 
 $file_path="../data/down/2011/03/21/"; 
 $file_name = urldecode($file_name); 
  
 // ../ is not allowed in the file name 
 if (!ereg("(\.\.\/)", $file_name)) 
 { 
 // Does the file exist? 
 if (file_exists($file_path . $file_name)) 
 { 
 $fp = @fopen( $file_path . $file_name, "r" ); 
 //Prompt the user to download the new torrent file. 
 header("Expires: 0" ); 
 header("Pragma:public" ); 
 header("Cache-Control:must-revalidate,post-check=0,pre-check=0" ); 
 header("Cache-Control:public"); 
 header("Content-Type:application/octet-stream" ); 
  
 if (strstr($_SERVER["HTTP_USER_AGENT"],"MSIE")){ 
 header("Content-Disposition:attachment;filename=".urlencode($file_name) ); 
 }else{ 
 header("Content-Disposition:attachment;filename=".$file_name ); 
 } 
 header("Content-transfer-encoding: binary"); 
 header("Content-length:".@filesize( $file_path . $file_name )); 
  
 @fpassthru( $fp ); 
 @fclose( $fp ); 
  } 
 exit(); 
 }
