Question

我无法让jQuery专注于输入字段。我忽略了一些明显的东西吗？在Firefox 56中，此代码对我不起作用。此外，在Chrome中，它随机无法正常工作 - 如果我模糊字段并重新加载代码段，它就不会聚焦。从来没有遇到过这个问题。

    public async Task BulkUpsertData(List<MyObject> newUpsertDatas)
    {
        var usernames = newUpsertDatas.Select(p => p.Username);
        var filter = Builders<MyObject>.Filter.In(p => p.Username, usernames);

        //Find all records that are in the list of newUpsertDatas (these need to be updated)
        var collection = Db.GetCollection<MyObject>("MyCollection");
        var existingDatas = await collection.Find(filter).ToListAsync();

        //loop through all of the new data, 
        foreach (var newUpsertData in newUpsertDatas)
        {
            //and find the matching existing data
            var existingData = existingDatas.FirstOrDefault(p => p.Id == newUpsertData.Id);
            //If there is existing data, preserve the date created (there are other fields I preserve)
            if (existingData == null)
            {
                newUpsertData.DateCreated = DateTime.Now;
            }
            else
            {
                newUpsertData.Id = existingData.Id;
                newUpsertData.DateCreated = existingData.DateCreated;
            }
        }

        await collection.DeleteManyAsync(filter);
        await collection.InsertManyAsync(newUpsertDatas);
    }

$(document).ready(function() {
  $('#focus').focus();
});

更新：关闭浏览器并重新打开，问题神奇地消失了。不知何故，Firefox失去了响应此事件的能力 - 我将这归结为浏览器或操作系统错误。留下问题可能对其他人有帮助。

jQuery focus（）不起作用（使用Firefox 56）
