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）

  var code = e.detail.value.ids //identity 为你输入的身份证
