javascript - Removing image src attribute -


एक छवि टैग पर src विशेषता को हटाना नहीं लगता आईओएस (7) या एंड्रॉइड (किटकैट) पर नजर डालने के लिए न तो एक रिक्त मूल्य के लिए विशेषता को बदलता है। अपेक्षित के रूप में डेस्कटॉप ब्राउज़र्स काम करते हैं

यह विशेषता हटाता है, लेकिन दृश्य परिवर्तन को प्रतिबिंबित नहीं करता है: $ ('# imgPreview')। RemoveAttr ('src');

यह विशेषता को बदलता है लेकिन दृश्य परिवर्तन को प्रतिबिंबित नहीं करता है: $ ('# imgPreview')। Attr ('src', '');

यदि विशेषता को एक वैध छवि पथ में बदल दिया गया है, दृश्य देखता है: $ ('#imgPreview') .attr ('src', 'http: //some/image/path.jpg');

मेरे पास एक साधारण परीक्षण का मामला है जो इस मुद्दे को दिखाता है।

क्या कोई तरीका है कि मैं src को रिक्त स्थान पर बदलने के बाद एक लाल रंग को लागू कर सकता हूं? मूल्य या src विशेषता को पूरी तरह से हटाया जा रहा है?

इस तरह का स्निपेट: 

  $। fn.redraw = function () {return.hide ()। शो (0); };   
 या शायद बेहतर:  
  $। Fn.redraw = function () {return.Each (function () {var zIndex = $ (यह )। सीएसएस ('जेड-इंडेक्स'); $ (यह)। सीएसएस ('जेड इंडेक्स', - 1)। सीएसएस ('जेड-इंडेक्स', ज़ींडेक्स);}); };   
 तब इसे यूज़::  
  $ ('# imgPreview') के रूप में प्रयोग करें। removeAttr ('src')। redraw ();

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
