php+javascript 静态化简单实例

2022-07-15 80酷酷网 80kuku.com

1. php生成js文件:

php代码:
<?php
a=array(
array('title'=>'本地新闻1',ln=>'#'),
array('title'=>'本地新闻2',ln=>'#'),
array('title'=>'本地新闻3',ln=>'#')

);//实际操作中可通过数据库得到记录集数组
news=' var a=['; //把该数组转化为javascrīpt形式

for(i=0;i<count(a);i++) {

if(i==count(a)-1) {
news.='{'
."title:'"
.a[i][title]."'"
.","
."ln:'"
.a[i][ln]
.'\'}';
}else {
news.='{'
."title:'"
.a[i][title]."'"
.","
."ln:'"
.a[i][ln]
.'\'},'; //如不是最后一个数据,则用逗号隔开,否则结束
}
}

news.='];';
fh=fopen("file.js","w");
fwrite(fh,news);
fclose(fh); //写入js
?>

2.html 文件

php代码: <!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>无标题文档</title>
</head>

<body>
<div id="news" > //定义显示的格式,先通过display:none 隐藏
<table border="1" bordercolor="#FF0000">
<tr>
<td><a href="link">title</a></td>
</tr>
</table>
</div>
<scrīpt language="javascrīpt" src="file.js"> //引用js

</scrīpt>
<scrīpt language="javascrīpt" >

news_obj=document.getElementById('news');
e=news_obj.innerHTML;
re=/\title/g; //正则,匹配title
re2=/\link/g; // 匹配link
for(i=0;i<a.length;i++) {
tmp=e.replace(re,a[i].title); //用a[i].title代替取出的title
tmp=tmp.replace(re2,a[i].ln);
document.write(tmp); //显示文本
}
</scrīpt>
<table width="200" border="1">

</table>
</body>
</html>
