微信小程序：验证手机号 身份证 邮箱（正则表达式）

手机号验证：

var phones = e.detail.value.phone
var myreg = /^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1})|(17[0-9]{1}))+\d{8})$/;
if (!myreg.test(phones)) {
wx.showToast({
title: '手机号格式不正确！',
icon: 'none',
duration: 1500
})
return false;
}

身份证号验证（不严格）

if (!(/(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/.test(e.detail.value.ids))) {
wx.showToast({
title: '身份证号码有误',
duration: 2000,
icon: 'none'
});
return false;

}

邮箱验证

var emil = e.detail.value.emil
var myregs = /^[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*\.[a-zA-Z0-9]{2,6}$/;
if (!(myregs.test(emil))) {
wx.showToast({
title: '邮箱输入有误',
duration: 2000,
icon: 'none'
});
return false;
}

身份证验证（严格验证）
