本文实例讲述了Ajax+PHP实现的模拟进度条功能。分享给大家供大家参考,具体如下:
一 代码
fun.js:
function progress(){ setInterval("beginProgress()", 200); } function beginProgress(){ $.get("progress.php", null, function(data){ $("#pg").css("width", data+"%"); $("#pgtext").html("The progress is "+data+"%"); }); }
index.php:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>jQuery制作进度条</title> </head> <script language="javascript" src="js/jquery-1.3.2.js"></script> <script language="javascript" src="js/fun.js"></script> <body> <div style="width:200px; height:12px; border:1px solid #0000FF"> <div id="pg" style="width:0%; height:100%;background-color:#0000FF"></div> </div> <br> <div id="pgtext" style="width:100px; height:20px"></div> <br> <input type="button" value="开始" onclick="progress()" /> </body> </html>
progress.php:
<?php $file = "./count.txt"; $fp = fopen($file, "r"); $txt = fread($fp, filesize($file)); echo $txt; $fp1 = fopen($file, "w"); if($txt<100){ $txt++; fwrite($fp1, $txt); }else{ fwrite($fp1, 1); } fclose($fp1); fclose($fp); ?>
二 运行结果
希望本文所述对大家PHP程序设计有所帮助。
