    मुझे इस लाइन को चलाने की आवश्यकता है जावास्क्रिप्ट: 

      @ मॉडल.save ({name: @ some_element.val ()})   
     लेकिन कुंजी, जो इस मामले में < कोड> नाम , एक चर के मूल्य के आधार पर बदल जाएगा। चर कुंजी का स्ट्रिंग प्रतिनिधित्व है। तो इस मामले में, वेरिएबल  "name"  है। मैं सही कुंजी को निर्दिष्ट करने के लिए चर का उपयोग कैसे कर सकता हूं? यदि मैं सीधे चर नाम का उपयोग करता हूं तो उसे कुंजी के रूप में ही व्याख्या की जाती है।   
     
     
      var obj = {}; Obj [varName] = @ some_element.val (); @ Model.save (obj);

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...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c# - GetType() == type perfomance question -

-
I am making an XNA game and I am calling the following updates 2 to 20 times the code. I tried googling and it seems that it is half slow, so I thought I was asking what kind of fast way to compare the type? code: Public modifier for this [type type] {for (int i = 0; i & lt; this.Qount; i ++) {if ( It [I.] Type GETType () ==) {Please return this [ii]; }} New NotImplementedException Throw ("Fix It"); } Set {for (int i = 0; i & lt; this.Qount; i ++) {if (this [i]. Type GetType () ==) {this [i] = value; }} If (System. Diagnostics.Debugor.ISAcredited) system. Diagnostics. Debugger. Break (); }} This code is in the modifier collection section which comes from a list. The modifier is a part of the particle engine. In addition, my game is not in a situation where I can actually do this test, so I can not test it, but should it work right? I read something about runtime typhanies, which is fast, should I use it? Thanks a lot! Edit: What I'm aiming to do ...
