EL表达要取的值中包含双引号"" 单引号'' 怎么办?撒分!
EL表达要取的值中有双引号""也有单引号'' 怎么办?
如 <input type="text" value="${user.name}" 这种情况如果name本包含双引号和单引号咋办,用[]来取貌似都不行啊

楼主，在后台数据查询出来的时候，要返回页面上的值有单双引号的，你可以写个方法转义一下，应该就行了。像这种一样：

//特殊字符转为Html

public static String toHtml(String s) {

    s = Replace(s,"&","&");

    s = Replace(s,"<","&lt;");

    s = Replace(s,">","&gt;");

    s = Replace(s,"\t","    ");

    s = Replace(s,"\r\n","\n");

    s = Replace(s,"\n","<br>");

    s = Replace(s,"  "," &nbsp;");

    s = Replace(s,"'","&#39;");

    s = Replace(s,"\\","&#92;");

    return s;

}

//逆

public static String unHtml(String s){	

    s = Replace(s,"<br>","\n");

    s = Replace(s,"&nbsp;"," ");

    s = Replace(s,"&lt","<");

    s = Replace(s,"&gt",">");

    s = Replace(s,"&amp","&");

    return s;

}

引进JSTL Funciton

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>

特殊字符转义

<input type="text" value="${fn:escapeXml(user.name)}" />
