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>
