Java中回车换行替换为的两种方法

package cjw;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class ReplaceCRLF {

/**

* @param args

*/

public static void main(String[] args) {

// TODO 自动生成方法存根

String content = "";

System.out.println(new ReplaceCRLF().rep1(content));

System.out.println(new ReplaceCRLF().rep2(content));

}

//第一种

private String rep1(String content){

Pattern CRLF = Pattern.compile("(\r\n|\r|\n|\n\r)");

Matcher m = CRLF.matcher(content);

if(m.find()){

content = m.replaceAll("");

}

return content;

}

//第二种

private String rep2(String content){

return content.replaceAll("(\r\n|\r|\n|\n\r)", "");

}

}

JavaScript中替换为回车换行

var content='';

var newContent=content.replace(/\/gi,"\r\n");
