如果是这样的字符串，那么<?JS ...JS?>中的字符串匹配成功。
var test = "<span>123123<?JS1231231</span>2JS?>123123<?JS12JS?><span>3</span><?JS13JS?>";
var reg = new RegExp("<\\?JS(.*?)JS\\?>", "g");
test.replace(reg, function(element) {
alert(element);
});
但是，如果<?JS ....\r\n ....JS?>中出现了换行，用上面的方法就不行了
var test = "<span>123123<?JS123123\n1</span>2JS?>123123<?JS12JS?>\r\n<span>3</span><?JS \n13JS?>";
var reg = new RegExp("<\\?JS(.*?)JS\\?>", "g");
test.replace(reg, function(element) {
alert(element);
});
在mode中加入m也没有效果，请问这是为什么？
相同的功能用java就可以实现：
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Test {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String test = "<span>123123<?JS123123\r\n1</span>2JS?>123123<?JS12JS?>\r\n<span>3</span><?JS \n13JS?>";
Pattern pattern = Pattern.compile("<\\?JS.*?JS\\?>", Pattern.DOTALL);
Matcher matcher = pattern.matcher(test);
while(matcher.find()) {
System.out.println(matcher.group(0).trim());
}
}
}
