Question

目前，格式是下一部手机

123-123-1123

我想要下一个表格：

(123)456-7890

如何将格式更改为我想要的任何形状？

<input class="" type="text" name="primary_phone" id="primary_phone" maxlength="10" placeholder="1234567890">

$("#primary_phone").blur(function() {
    text = $(this).val().replace(/(\d{3})(\d{3})(\d{4})/, "$1-$2-$3");
    $(this).val(text);
});

Answer 1

＆＃13;

    var phone = "123-123-1123";
    var newPhone = "(" + phone.replace("-", ")");
    alert(newPhone);

＆＃13;

Answer 2

转换由正则表达式处理，正则表达式构成文本.replace()函数的第一个参数，输出是第二个参数。这里需要改变第二个参数的格式。

$("#primary_phone").blur(function() {
  text = $(this).val().replace(/(\d{3})(\d{3})(\d{4})/, "($1)$2-$3");
  $(this).val(text);
});
//=> (123)456-7890

希望有所帮助。：）

Answer 3

$( "#primary_phone" ).blur(function() {
            text = $(this).val().replace(/(\d\d\d)(\d\d\d)(\d\d\d\d)/, '($1)$2-$3');
        $(this).val(text);
});
