http://www.jackxiang.com/index.php zh-cn http://www.jackxiang.com/post// jack <xdy108@126.com> Wed, 06 Mar 2019 04:01:46 +0000 http://www.jackxiang.com/post// Html textarea：
<textarea name="˝" cols="60" rows="20" id="textareaLeft"></textarea> <textarea name="textareaRight" cols="60" rows="22" id="textareaRight"></textarea>

javasciprt,先批量替换掉下划线为点号，再正则匹配出所有包含IP行里的IP，如下：
var  s = $("#textareaLeft").val(); s = s.replace(/\_/g, "."); var ipsArr = s.match(new RegExp("\\d{1,3}\.\\d{1,3}\.\\d{1,3}\.\\d{1,3}","g")); var ips = ipsArr.join('\r\n'); $("#textareaRight").val(ips);

输入素材：

  elk_logstash_bj_yz_10_73_211_106
  elk_logstash_bj_yz_10_73_211_118
  elk_logstash_bj_yz_10_73_211_119


输出素材：
10.73.211.106
10.73.211.118
10.73.211.119

Jquery写法，加上IP去重：
Html触发部分：
<a href="javascript:void(0);" id=analysisIps name=analysisIps>[提取Ip地址]</a>

$('#analysisIps').click(function() {     var  s = $("#textareaLeft").val();     if(typeof s == "undefined" || s == null || s == "")         return false;     s = s.replace(/\_/g, ".");     var ipsArr = s.match(new RegExp("\\d{1,3}\.\\d{1,3}\.\\d{1,3}\.\\d{1,3}","g"));     var hash=[],arrIpSorted=[];                                                                                                                                   for (var i = 0; i < ipsArr.length; i++) {       hash[ipsArr[i]]!=null;       if(!hash[ipsArr[i]]){         arrIpSorted.push(ipsArr[i]);         hash[ipsArr[i]]=true;       }     }     var ips = arrIpSorted.join('\r\n');     $("#textareaRight").val(ips); });
