碰见一个小程序的验证码输入,有4个input,输入第一个的时候第二个聚焦,这个时候软键盘就会收起再弹出,很大的一个bug,最后只能手动写一个软键盘,现在可以分享出来,让大家看一看代码:,这是页面完成后的图片,下面代码献上:
html部分:
<view class=‘container‘>
<view class=‘note_box‘>
<view class=‘ntb_head‘>请输入您的短信验证码</view>
<view class=‘nt_input‘>
<input type=‘number‘ bindinput=‘inuputNum‘ data-ind="1" focus=‘{{inFocus==0?true:false}}‘ disabled maxlength=‘1‘ value=‘{{num1}}‘></input>
<input type=‘number‘ bindinput=‘inuputNum‘ data-ind="2" maxlength=‘1‘ focus=‘{{inFocus==2?true:false}}‘ disabled value=‘{{num2}}‘></input>
<input type=‘number‘ bindinput=‘inuputNum‘ data-ind="3" maxlength=‘1‘ focus=‘{{inFocus==3?true:false}}‘ disabled value=‘{{num3}}‘></input>
<input type=‘number‘ bindinput=‘inuputNum‘ data-ind="4" maxlength=‘1‘ focus=‘{{inFocus==4?true:false}}‘ disabled value=‘{{num4}}‘></input>
</view>
<view class=‘note_hint‘>验证码已发送到158****0771,请注意查收</view>
<view class=‘note_anmiteTime‘><text>{{anTime}}</text>秒后可从新获取</view>
</view>
<view class=‘numModal‘>
<view>
<view bindtap=‘clickNum‘ data-num=‘1‘>1</view>
<view bindtap=‘clickNum‘ data-num=‘2‘>2</view>
<view bindtap=‘clickNum‘ data-num=‘3‘>3</view>
</view>
<view>
<view bindtap=‘clickNum‘ data-num=‘4‘>4</view>
<view bindtap=‘clickNum‘ data-num=‘5‘>5</view>
<view bindtap=‘clickNum‘ data-num=‘6‘>6</view>
</view>
<view>
<view bindtap=‘clickNum‘ data-num=‘7‘>7</view>
<view bindtap=‘clickNum‘ data-num=‘8‘>8</view>
<view bindtap=‘clickNum‘ data-num=‘9‘>9</view>
</view>
<view>
<view class=‘color_e‘></view>
<view bindtap=‘clickNum‘ data-num=‘0‘>0</view>
<view class=‘color_e‘ bindtap=‘clickNum‘ data-num=‘x‘>X</view>
</view>
</view>
</view>
