javascript - Assigning DOM style to var -

-

अगर मैं टाइप करता हूं तो किसी कारण से: 

  var i = document.getElementById (' । नकली ') style.backgroundPosition;   
 मुझे अपरिभाषित मिलता है।  
 हालांकि,  
  document.getElementById ('नकली')। Style.backgroundPosition;   
 
    
 = "Text"> 
 जब मैं किसी ऐसे तत्व पर कोड की उस पंक्ति का उपयोग करता हूं जो वास्तव में क्रोम में मौजूद है, तो मुझे एक खाली स्ट्रिंग के बराबर  i  मिलता है। आप यहां इस जेएसएफडल में देख सकते हैं:।  
 अतः, यदि आप अपरिभाषित हो रहे हैं, तो संभवतः आपका ऑब्जेक्ट "नकली" मौजूद नहीं है जब आप कोड चलाते हैं।  
  element.style.backgroundPosition  केवल उस वास्तविक ऑब्जेक्ट के लिए सीधे एक वास्तविक इनलाइन शैली सेटिंग्स या प्रोग्रामेंटल मान सेट करेंगे यह स्टाइलशीट से गणना की गई शैलियों की वापसी नहीं करेगा। यदि आप उस विशेषता के लिए मौजूदा शैली सेटिंग प्राप्त करना चाहते हैं, तो आपको इस तरह से कुछ का उपयोग करना होगा:  
  var i = window.getComputedStyle (document.getElementById ('fake'), रिक्त) .getPropertyValue ( 'पृष्ठभूमि स्थिति');   
 और, यह IE में अलग है यह वह जगह है जहां jQuery या YUI की रूपरेखा बहुत उपयोगी है।  
 jQuery में, यह सिर्फ यह होगा:  
  var i = $ ("# fake") सीएसएस ( 'backgroundPosition');

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
