php、js、java的正则替换文本方式制作模板内容输出
java版
import java.util.HashMap;
import java.util.Map;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class TestRex {
public static void main(String[] args) {
Map
map.put("name", "penngo");
map.put("date", "2013-01-17");
Pattern p = Pattern.compile("");
String str = ", Hello ";
Matcher m = p.matcher(str);
StringBuffer sb = new StringBuffer();
boolean result = m.find();
while (result) {
String key = m.group(1);
String value = map.get(key);
m.appendReplacement(sb, value);
result = m.find();
}
m.appendTail(sb);
System.out.println(sb.toString());
}
}
php版
$data = array('name'=>'penngo', 'date'=>'2013-01-17');
function replaceStr($key, $data){
return $data[$key];
}
$str = ', Hello ';
$str = preg_replace("//ise", "replaceStr('\\1', \$data)", $str);
echo $str;
?>
js版
var date = {'name':'penngo', 'date':'2013-01-17'};
var str = ', Hello ';
str = str.replace(//g, function($0, $1){
var value = date[$1];
return value;
});www.2cto.com
document.write(str);
运行结果输出:
2013-01-17, Hello penngo
