<view class="sms-ts-input" style="padding:16rpx 0">
                        <text wx:if="{{!ocr.placeAreaShow}}" bindtap="textToArea">{{ocr.idaddress}}</text>
                        <textarea 
                            wx:if="{{ocr.placeAreaShow}}" 
                            type="text" 
                            bindinput="idaddressInputChanged" 
                            bindblur="areaToText"
                            placeholder="请输入地址" 
                            value="{{ocr.idaddress}}" 
                            disabled="{{!page.ocr.isIdaddressAllowEdit}}" 
                            auto-height="true" 
                            auto-focus="true"
                            style="line-height:1.5em;width:100%;" 
                            class="self-place-textarea">
                        </textarea>
                    </view>

idaddressInputChanged(i) {
    this.data.ocr.idaddress = i.detail.value, this.ocrCommonInputCheck()
  },
// text ->  textarea
  textToArea() {
    this.setData({
      "ocr.placeAreaShow": true
    })

  // textarea -> text 
  areaToText() {
    const address = this.data.ocr.idaddress
    this.setData({
