Question

此搜索的链接有时有效，但很少见。

<div class="input-group col-md-5 col-md-offset-3" style="margin-top:2%;">
     <input id="Buscar_Input" ng-model="Busca.input" autocomplete="off"
            type="text" class="form-control"
            ng-keyup="BuscaPreviewAbrir({'input': Busca.input, 'result': 'input'}, $event)"
            ng-focus="BuscaPreviewAbrir({'input': Busca.input, 'result': 'input'})"           
            ng-blur="BuscaPreviewFechar({'result': 'input'})" 
            placeholder="Faça a sua pesquisa..."
            aria-describedby="basic-addon2" style="width: 120%;margin-left: -20%;">
     <span class="input-group-addon btn btn-farmatual" id="Buscar_Button"
           pw-buscar="Buscar_Input" ng-click="Buscar(Busca.input)">
       <i class="fas fa-search"></i>
     </span>
     <div class="input-group-dropdown" ng-show="BuscaPreview.input.length">
         <div ng-repeat="BuscaPreview in BuscaPreview.input"
              class="input-group-dropdown-item busca-dropdown"
              href="{{BuscaPreview.UrlLink}}">
           <a ng-href="{{BuscaPreview.UrlLink}}"
              bind-attr="BuscaPreview.SeoHtmA"
              ng-class="{'busca-dropdown-selecionado': BuscaPreview.Selecionado}">
               <img ng-if="BuscaPreview.ProdutoMidiaItems[0].UrlP"
                    ng-src="{{BuscaPreview.ProdutoMidiaItems[0].UrlP}}"
                    bind-attr="BuscaPreview.ProdutoMidiaItems[0].SeoHtmImg"
                    href="{{BuscaPreview.UrlLink}}" />
               <font ng-href="{{BuscaPreview.UrlLink}}">{{BuscaPreview.Nome}}
               </font>
            </a>
          </div>
      </div>
</div>

我想知道问题是否存在。
