javascript - Change transition time on onmouseover and onmouseout? -

-

यह मेरा HTML है 

  & lt; img class = "logo" src = "css /images/logo.png "align =" center "onmouseover =" this.src = 'css / images / logohov.png' "onmouseout =" this.src = 'सीएसएस / चित्र / लोगो.png' "& gt; & Lt; / img & gt;   
 क्या कोई तरीका है कि मैं संक्रमण के समय को बदल सकता हूँ? मैंने संक्रमण जोड़ा है: सभी 0.3s आसानी; क्लास लोगो पर लेकिन यह कुछ भी नहीं करता है।  
 धन्यवाद   
 
 
 आप बदल रहे हैं स्रोत विशेषता जो कि संक्रमण की संपत्ति के साथ प्रयोग नहीं की जा सकती, भले ही आपने सीएसएस की सामग्री की संपत्ति का इस्तेमाल किया हो, फिर भी इसे संक्रमण के साथ प्रयोग नहीं किया जा सकता, इसके बजाय दो आईएमजी टैग की कोशिश करें, और एक को छिपाने के लिए और एक दूसरे को हॉवर पर संक्रमण के साथ दिखाएं।  
 कुछ उदाहरण हैं

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

c++ - Qt::make_shared for creating QSharedPtr as std::make_shared for creating std::shared_ptr -

-
As stated in the Barjini Stroustrup's "A Tour of C ++", and a known C ++ 14 practice As such, someone should avoid the naked code in the new and delete . Provides std :: make_shared and std :: make_unique to create smart pointers to store allocated items in the standard library. However, it is not possible to use these routines for non-standard smart pointers, such as QT's own memory management model (with parent), but also smart pointer class like Provides QSharedPointer and QPointer (although later it is not actually a brochure indicator). My question is: Is not it convenient to create Qt analog of std :: make_shared ? To like it, QSharedPtr : Namespace Qt {template & lt; Class T, squares ... Args & gt; QSharedPointer & LT; T & gt; Make_shared (erg & amp; ... args) {return QSharedPointer & lt; T & gt; (New t (std :: forward & lt; ergos & gt; (args) ...)); }} or to create this, QPointer : named place ...
