<script>tester();</script>
复制代码
test6.php
header('Content-Type: application/x-javascript; charset=UTF-8');
$str = $_GET["str"];
?>
// javascript document
// by bbs.it-home.org
alert('');
function tester(string)
{
string ? alert(string) : alert('you call a function named tester');
}
?>
复制代码
第二种方法：
test.php
<script> <li> function loadjs(url,callback){ <li> var head = document.getElementsByTagName("head")[0]; <li> var script = document.createElement('script'); <li> script.onload = script.onreadystatechange = script.onerror = function (){ <li> if (script && script.readyState && /^(?!(?:loaded|complete)$)/.test(script.readyState)) return; <li> script.onload = script.onreadystatechange = script.onerror = null; <li> script.src = ''; <li> script.parentNode.removeChild(script); <li> script = null; <li> callback(); <li> } <li> script.charset = "gb2312"; <li> script.src = url; <li> try { <li> head.appendChild(script); <li> } catch (exp) {} <li> } <li> <li> function loadmultijs(url,callback){ <li> if(Object.prototype.toString.call(url)==='[object Array]'){ //是否数组 <li> this.suc = 0; //加载计数 <li> this.len = url.length; //数组长度 <li> var a = this; <li> for(var i = 0;i < url.length;i++){ <li> loadjs(url[i],function(){ a.suc++; if(a.suc == a.len) try{callback();}catch(e){} }); <li> } <li> } <li> else if(typeof(url) == 'string') loadjs(url,callback); <li> } <li> <li> loadjs("test5.php?return=value",function(){ alert(value); tester(value); }); <li> </script>
复制代码
test5.php
var value="this is value.";
复制代码
加载多JavaScript文件的实例：
var url = [
'ajax.php?ajax=1',
'functions.js'
];
loadmultijs(url,function(){ alert("加载完毕。"); /* 这里可以调用动态加载的JS文件的数据或方法 */ });
复制代码
2. 动态加载css文件
test.php
this document has a #e4e4e4 background, a 300px/400px div, and a arial/24px/red words.
复制代码
div.php
// declare the output of the file as CSS
header('Content-type: text/css');
// include the script
//include('others.php');
$width = $_GET['w'];
$height = $_GET['h'];
?>
复制代码
div{width:=$width?>px;height:=$height?>px;border:blue 1px solid;}
复制代码
fonts.php
// declare the output of the file as CSS
header('Content-type: text/css');
// include the script
//include('others.php');
$size = $_GET['s'];
$color = $_GET['c'];
?>
body{font-family:arial;font-size:=$size?>px;color:=$color?>}
复制代码
就是这些了，php动态加载js与css的方法就介绍完了，建议大家亲自动手测试下，看看具体的实现有没有问题。
