使用wx.hideKeyboard()，提示input not exists，实际键盘未收回，如何解决？

js

  // 获取搜索框内容
  getkeyvalue:function(e){
    this.setData({
      keyword:e.detail.value,
    })
  },
  // 搜索提交功能
  search: function (e) {
    wx.hideKeyboard();
    var keyword = this.data.keyword;
    App.sr.track('search', {
      "keyword": keyword?keyword:' ',
    })
    console.log(keyword)
    wx.navigateTo({
      url: '/pages/category/category?keyword=' + keyword+'&searchtype=plp'
    })
  },

wxml

            <form class="input" >
              <input name="search" class="keywrod"  value="{{keyword}}" confirm-type="search" bindinput="getkeyvalue" bindconfirm="search" />
              <button plain hover-class="none" style="border:none; z-index:1;" class="icon-warp" bindtap="search" >
                <text>| </text>
                <image class="icon"></image>
              </button>
            </form>
