我有这个 HTML 转义方法:
public static String stringToHTMLString(String string) {
StringBuffer sb = new StringBuffer(string.length());
// true if last char was blank
boolean lastWasBlankChar = false;
int len = string.length();
char c;
for (int i = 0; i < len; i++)
{
c = string.charAt(i);
if (c == ' ') {
// blank gets extra work,
// this solves the problem you get if you replace all
// blanks with , if you do that you loss
// word breaking
if (lastWasBlankChar) { // NOT going into this loop
lastWasBlankChar = false;
sb.append(" ");
}
else {
lastWasBlankChar = true;
sb.append(' ');
}
}
else {
lastWasBlankChar = false;
//
// HTML Special Chars
if (c == '"')
sb.append(""");
else if (c == '&')
sb.append("&");
else if (c == '<')
sb.append("<");
else if (c == '>')
sb.append(">");
else if (c == '\n')
// Handle Newline
sb.append("<br/>");
else {
int ci = 0xffff & c;
if (ci < 160 )
// nothing special only 7 Bit
sb.append(c);
else {
// Not 7 Bit use the unicode system
sb.append("&#");
sb.append(new Integer(ci).toString());
sb.append(';');
}
}
}
}
return sb.toString();
}
当我用字符串“boy y”传递它时,它返回“boy y”。当我将输入字符串更改为“bo>y”时,它正确地转义了字符串。知道为什么空间逃逸不起作用吗?
谢谢。
