今天碰到一个很奇怪的问题，看看如下代码：
SimpleDateFormat dateFormat = new SimpleDa

复制代码
代码如下:
teFormat("yyyy年MM月dd日 E ");
String date = dateFormat.format(new Date());

本意是想要打印出来XXXX年XX月XX日 星期X
问题出在如下代码，当我想要取得格式化之后的数据时，在value=方法取值时，只能取到“XXXX年XX月XX日”，后面的“星期X”一直取不到

复制代码
代码如下:





①后来想到，有可能是HTML转义问题，于是就将"yyyy年MM月dd日 E "中的空格全部去掉了，结果可以正常取值了或者改为“yyyy年MM月dd日-E”
②还有一种方法，只要使用转义字符将准备显示的字符串中内容逐个替换即可

复制代码
代码如下:

String result = "";
for (int i = 0; i switch (date.charAt(i)) {
case 'result += "break;
case '>':
result += ">";
break;
case '&':
result += "&";
break;
case '"':
result += "\"";
break;
case '\'':
result += "'";
break;
case ' ':
result += " ";
break;
default:
result += date.charAt(i);
}
}
%>

参考内容如下：
HTML原代码 显示结果 描述
< < 小于号或显示标记
> > 大于号或显示标记
& & 可用于显示其它特殊字符
" " 引号
