实现思路:
1、放置一个输入框,隐藏其文字和位置,同时设置支付输入框(表格)样式
2、当点击输入框时设置输入框为聚焦状态,唤起键盘,点击空白处,失去焦点,设为失去焦点样式,因为输入框宽高为0,所以不会显示输入框和光标,实现隐藏。
3、限制输入框最大字数并且监听输入框状态,以输入框值的长度作为输入框(表格)内容的渲染条件
4、点击提交按钮时,获取输入框内容。
1、wxml:
<form bindsubmit="formSubmit"> <view class='content'> <block wx:for="{{Length}}" wx:key="item"> <input class='iptbox' value="{{Value.length>=index+1?Value[index]:''}}" disabled password='{{ispassword}}' catchtap='Tap'> </input> </block> </view> <input name="password" password="{{true}}" class='ipt' maxlength="{{Length}}" focus="{{isFocus}}" bindinput="Focus"></input> <view> <button class="btn-area" formType="submit">Submit</button> </view> </form> |
2、js:
Page({ /** * 页面的初始数据 */ data: { Length:6, //输入框个数 isFocus:true, //聚焦 Value:"", //输入的内容 ispassword:true, //是否密文显示 true为密文, false为明文。 }, Focus(e){ var that = this; console.log(e.detail.value); var inputValue = e.detail.value; that.setData({ Value:inputValue, }) }, Tap(){ var that = this; that.setData({ isFocus:true, }) }, formSubmit(e){ console.log(e.detail.value.password); }, }) |
3、wxss:
content{ display: flex; justify-content: space-around; align-items: center; margin-top: 200rpx; } iptbox{ width: 80rpx; height: 80rpx; border:1rpx solid #ddd; border-radius: 20rpx; display: flex; justify-content: center; align-items: center; text-align: center; } ipt{ width: 0; height: 0; } btn-area{ width: 80%; background-color: orange; color:white; } |
