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
