javascript - Selecting class name of a span tag -

-

मेरे पास इस तरह की अवधि है 

  & lt; span class = 'class_name' & gt; ब्ला ब्ला & lt; / span & gt;

मैं इस अवधि के वर्ग नाम का चयन करना चाहता हूं। उस आईएएम के लिए इस। क्लास का उपयोग कर फ़ायरफ़ॉक्स में इसका काम ठीक है। लेकिन एक्सप्लोरर इसके लिए नहीं ...

मैं इसे कैसे ठीक कर सकता हूं ??

<पी > यह एक्सप्लोरर में भी काम करना चाहिए आप कोशिश कर सकते हैं, हालांकि: 

  $ (यह) .attr ('class');

To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
