Question

点击列表项后，我试图通过jQuery关闭我的Bootstrap 3下拉列表。

HTML

File "test.py", line 10, in <module>
    conf=(SparkConf().setMaster('local').setAppName('a').setSparkHome('/home/dirk/spark-1.4.1-bin-hadoop2.6/bin'))
  File "/home/dirk/spark-1.4.1-bin-hadoop2.6/python/pyspark/conf.py", line 104, in __init__
    SparkContext._ensure_initialized()
  File "/home/dirk/spark-1.4.1-bin-hadoop2.6/python/pyspark/context.py", line 229, in _ensure_initialized
    SparkContext._gateway = gateway or launch_gateway()
  File "/home/dirk/spark-1.4.1-bin-hadoop2.6/python/pyspark/java_gateway.py", line 48, in launch_gateway
    SPARK_HOME = os.environ["SPARK_HOME"]
  File "/usr/lib/python2.7/UserDict.py", line 23, in __getitem__
    raise KeyError(key)
KeyError: 'SPARK_HOME'

JS

<div class="btn-group">
    <button type="button" data-toggle="dropdown" class="btn btn-default dropdown-toggle">10 <span class="caret"></span></button>
    <ul class="dropdown-menu">
        <li><a href="javascript: void(0)">10</a></li>
        <li><a href="javascript: void(0)">20</a></li>
    </ul>
</div>

不幸的是，此解决方案不适用于IE和Chrome。事实上，在那之后我选择了几次，下拉停止显示元素。

使用Firefox似乎没有问题。我怎样才能解决我的问题？

谢谢

我注意到即使使用firefox我也有同样的问题

对于那些遇到同样问题的人，我找到了解决问题的技巧。

使用

$(this).dropdown("toggle");

取代

You should change the line that says:

`MongoClient.connect("mongodb://" + process.env.IP + ":" + process.env.PORT + "/[dbname]", function (err, db){ `

You are connecting to `process.env.PORT`, but that is not the port for mongodb.
Simply use the default connection url here, it should work: 

`mongodb://localhost:27017/[dbname]`

在点击IE和Chrome的问题后，Bootstrap 3关闭下拉列表
