我创建了一个类似于下面的JavaScript程序，它可以正常工作以删除Active，Pending验证文字，

I have created a JavaScript Program which something like below which working properly for removing Active, Pending verification text,

<script>
  function extracter() {

    var a = document.getElementById('input').value;

    document.getElementById('output').innerHTML =

    a.replace(/Active|Pending|Verification| /g, '');

  }
</script>

<textarea id="input"></textarea><br/>
<br/>

<input type="button" value="click" onclick="extracter()"/>
<br/>
<br/>
<textarea id="output"></textarea>

输出为，

 [e-mail]  12/05/2015  03:07
   [e-mail]  8/05/2015  01:07

我想要以下输出。只需帮我删除日期和时间，

And I want the below output. Just help me to remove "Date" and "Time",

   [e-mail]

推荐答案

尝试这个，我认为它会完成这项工作

Try this one, i think it will do the job

var a = document.getElementById('input').value;

document.getElementById('output').innerHTML = extractEmails(a).join('\n');

功能：

function extractEmails (text)
{
    return text.match(/([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);
}

这是小提琴

这里也是一个使用jQuery的例子使用jquery从批量文本中提取所有电子邮件地址
