Jquery: 在 focusout 上更改输入文本值
Jquery: change input text value on focusout
我有如下字段
输入文本固定为 11 位。
现在,当焦点移开时,我希望输入文本像下面这样更改
123-456-789-01
如何使用 Jquery
实现此目的
谁能指导我
您可以使用下面的正则表达式来格式化您的 phone phone = phone.replace(/(\d{3})(\d{3})(\d{3})(\d{2})/, "---");
并设置 maxlength
=11
$('#phone').focusout(function() {
function phoneFormat() {
phone = phone.replace(/[^0-9]/g, '');
phone = phone.replace(/(\d{3})(\d{3})(\d{3})(\d{2})/, "---");
return phone;
}
var phone = $(this).val();
phone = phoneFormat(phone);
$(this).val(phone);
});
$('#phone').focusout(function() {
function phoneFormat() {
phone = phone.replace(/[^0-9]/g, '');
phone = phone.replace(/(\d{3})(\d{3})(\d{3})(\d{2})/, "---");
return phone;
}
var phone = $(this).val();
phone = phoneFormat(phone);
$(this).val(phone);
});
