在AJAX更新后，输入不会得到焦点。 IE7

Question

我有一个包含多种表单的页面。用户可以修改内容，所有请求都通过AJAX完成。每个AJAX调用都会更新页面的一部分，其中包含一个表单。

更新后，所有输入表单都无法获得焦点。这种情况只发生在IE中，我在Chrome中尝试过，它运行得很好。

任何想法??

控制器

[HttpPost, ValidateInput(false)]
        public ActionResult SaveRiskAndRewardItem(int RiskAndRewardItemId, short RiskAndRewardRating, string Description)
        {
            RiskAndRewardItem model = RiskAndRewardItemModelBuilder.GetInstance().BuildOne(RiskAndRewardItemId);

            model.RiskAndRewardRating = RiskAndRewardRating;
            model.Description = Description;
            if (ModelState.IsValid)
            {
                _riskAndRewardItemRepository.Update(model);
            }
            return PartialView("_RiskAndRewardItem", model);
        }

查看

            <br />

            <input id="RiskAndRewardItemId" name="RiskAndRewardItemId" type="hidden" value="@Model.Id" />

            <textarea id="Description" class="htmleditor" name="Description" rows="5" cols="40">@Model.Description</textarea>
            <div style="text-align: right">

我喜欢4种不同的局部视图，每种视图在控制器中都有自己的方法。就像上面那个。
