用 readonly="readonly" 只读属性，js的定时器延迟一段时间后移除input的只读属性readonly，就可以了！
<input type="text" class="aui-input" name="phone" id="phone" placeholder="手机号码（登录账号）" data-rule="手机号码:required;mobile;" readonly="readonly" autocomplete="off">
<input type="password" class="aui-input" name="password" id="password" placeholder="密码" data-rule="密码:required;length[6~];" readonly="readonly" autocomplete="off">
<script>
setTimeout(function removeReadonly(){
var username=document.getElementById("phone");
var password=document.getElementById("password");
username.removeAttribute("readonly");
password.removeAttribute("readonly");
},20);
</script>
