解决方案：

1、建立WEB-INF/tags/format/enter.tag文件，其文件内容如下： 

<%@ tag body-content="scriptless" pageEncoding="utf-8" %><%@ attribute name="value" type="java.lang.String" required="true"%><%	if(value != null) {		int lengthh = value.length();		StringBuffer filtered = new StringBuffer(lengthh);		char prevChar = '\u0000';		char c;		for (int i = 0; i < lengthh; i++) {			c = value.charAt(i);			if (c == '"') {				filtered.append("\\\"");			} else if (c == '\'') {			 	filtered.append("\\'");			} else if (c == '\\') {			 	filtered.append("\\\\");			} else if (c == '\t') {				filtered.append("\\t");			} else if (c == '\n') {				if (prevChar != '\r') {					filtered.append("\\n");				}			} else if (c == '\r') {				filtered.append("\\n");			} else if (c == '\f') {				filtered.append("\\f");			} else if (c == '/') {				filtered.append("\\/");			} else {				filtered.append(c);			}			prevChar = c;		}		value = String.valueOf(filtered);	}		out.print(value);%>

2、页面运用，代码示例如下： 

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%@ taglib tagdir="/WEB-INF/tags/format" prefix="format" %>          	
    	
    	            

注：js中的特殊字符有：
