如何实现动态加载并执行JS脚本文件

Question

<script id="ds" type="text/javascript" src=""></script>放head里，在需动态加载并执行脚本的地方写 document.getElementById("ds").src="你的ASP生成脚本的URL";

Answer 1

说明如下： 
该文件使用了  im.xxxxxx.net下的NT2.asp文件：（A域） 
文件内容如下：                                                                              
var  lastScript;                                                                          
var  h=document.getElementsByTagName("head")[0];                                          
                                                                                            
function  loadScript(url){                                                                
var  f=document.createElement("script");                                                  
var  d=new  Date().getTime();                                                            
f.type="text/javascript";                                                                  
f.id=d;                                                                                    
f.src=url+'?'+d;                                                                            
h.appendChild(f);                                                                          
if(lastScript&&g(lastScript))g(lastScript).parentNode.removeChild(g(lastScript));          
lastScript=d;                                                                              
}                                                                                          
                                                                                            
function  g(x){return  document.getElementById(x)};                                      
function  b(x){                                                                            
alert(x)                                                                                  
};                                                                                        
                                                                                            
loadScript('http://www.xxxxxx.cn/alert.asp?aaa=1234&')//调用www.xxxxxx.cn（B域）中的JS文件  
                                                                                            
该文件调用www.xxxxxx.cn（B域）下的 alert.asp文件。（使用loadScript函数）                    
alert.asp内容如下：                                                                        
&lt;%                                                                                      
dim intA :intA= request("aaa")                                                          
%&gt;                                                                                      
var aa='ccc&lt;%=intA%&gt;';                                                                
b(aa);//调用im.xxxxxx.net中的函数                                                          
此时从www.xxxxxx.cn（B域）执行im.xxxxxx.net（A域）下的NT2.asp文件中的b函数。                ---> 
使用这种方法,可以解决部分跨域问题..省略需要在他人服务器上放服务器端代码的麻烦.

Answer 2

不需要ajax啊,这样就可以了
<script type="text/javascript" src="Sql.Asp"></script>
要不还得
eval(ajaxObj.responseText)
