Question

我使用正则表达式进行格式化

<p class="phone">2124771000</p>
 $(".phone").text(function(i, text) {
        text = text.replace(/(\d\d\d)(\d\d\d)(\d\d\d\d)/, "$1-$2-$3");
        return text;
    });

使用以上示例我可以转换212-477-1000

<p class="phone">ABC1234</p>

现在我想使用上面的文字制作 ABC-1234 字符串。

任何人都非常感谢，提前致谢

Answer 1

以下将检查3个大写字母后跟4个数字：

$(".phone").text(function(i, text) {
    text = text.replace(/([A-Z]{3})(\d{4})/, "$1-$2");
    return text;
});

Answer 2

如果你想在1个正则表达式中捕获它们。

您可以使用任一表达式|

例如

/^(\d{3})(\d{3})(\d{4})|([A-Z]{3})(\d{4})$/

function replacer(m, p1,p2,p3, p4,p5) {
  if (p1) return [p1,p2,p3].join('-')
  else return [p4,p5].join('-');
}

$(".phone").text(function(i, text) {
  text = text.replace(/^(\d{3})(\d{3})(\d{4})|([A-Z]{3})(\d{4})$/, replacer);
  return text;
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="phone">ABC1234</p>
<p class="phone">1231231234</p>
<p class="phone">XYZ2345</p>
<p class="phone">9999999999</p>

Answer 3

您可以针对ABC1234尝试此操作：

＆＃13;

$(".phone").text(function(i, text) {
  text = text.replace(/([a-z]+(?=\d+))/i, "$1-");
  return text;
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="phone">ABC1234</p>

＆＃13;

对于电话号码，请尝试：

＆＃13;

$(".phone").text(function(i, text) {
  text = text.replace(/(\d{3})(\d{3})(\d{4})/, "$1-$2-$3");
  return text;
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="phone">2124771000</p>

＆＃13;

Answer 4

你可以尝试这种模式

text = text.replace(/([a-zA-Z]+)(\d+)/, "$1-$2");
