合并网页中的多个script引用实现思路及代码

复制代码 代码如下:

<script type="text/javascript" src="limit.js"></script>
<script type="text/javascript" src="select.js"></script>
<script type="text/javascript" src="rating.js"></script>

复制代码 代码如下:

public class Handler1 : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{//原文链接：blog.csdn.net/bluceyoung
string[] js = context.Request.Url.LocalPath.Substring(1, context.Request.Url.LocalPath.Length - 5).Split('.');
StringBuilder sb = new StringBuilder();
foreach (string j in js)
{
sb.Append(ReadFile(j+".js"));
}
context.Response.Write(CompressStr(sb));
}
private string ReadFile(string fileName)
{
string directory = @"D:/SRC/bluceyoung/";
if (!File.Exists(directory + fileName))
{
return "";
}
string result;
using (FileStream fs = new FileStream(directory + fileName, FileMode.Open))
{
using (StreamReader sr = new StreamReader(fs))
{
result = sr.ReadToEnd();
}
}
return result;
}
private string CompressStr(StringBuilder sb)
{
while (true)
{
int length = sb.Length;
sb.Replace(" ", " ");
if (length == sb.Length)
break;
}
sb.Replace("/r/n", "").Replace("/t", "").Replace("; ", ";").Replace(" }", "}").Replace("} ", "}").Replace(" ;", ";").Replace(" {", "{").Replace("{ ", "{");
return sb.ToString();
}
public bool IsReusable
{
get
{
return false;
}
}
}

复制代码 代码如下:

<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpHandlers>
<add path="*.jsx" verb="*" type="BluceYoung.Handler1"/>
</httpHandlers><!--原文博客：blog.csdn.net/bluceyoung -->
</system.web>
</configuration>

复制代码 代码如下:

<script src="limit.select.rating.jsx" type="text/javascript"></script>
