  首先在wxml文件中加入form标签:

<form bindsubmit="formSubmit">
    <input name="email" placeholder="E-mail" /> 
    <button form-type="submit" class="send" >
    发送
    </button>
</form>

然后在js文件中加入formSubmit函数:

formSubmit:function(e){
    console.log(e.detail.value);
    var val = e.detail.value.email;
    var reg = /^[A-Za-z\d]+([-_.][A-Za-z\d]+)*@([A-Za-z\d]+[-.])+[A-Za-z\d]{2,4}$/; 
    if(reg.test(val)){
      console.log('输入正确');
    }else{
      console.log('输入不正确');
    }
  }

即可进行验证。
