asp.net mvc 3 - How to update a model field without calling the field explicitly in Javascript -

-

In my MVC3 application, I have a visual model, which I encode Jason, so I manipulate it in Javascript Can i

So suppose I have the following code: 

  var model =@HTML.Raw (Jason.excode (model));   
 Currently, the name of model.name is "name".  
 What I want to do now is another javascript object "obj" which is "value". When you change obj.Value, this model varies. Name.  
 So I want something:   preform  var obj = new object (); obj.Value = model.Name;   
 So now, if I obj.Value I change the value of this model, it does not even change the name. I should do this and I am not sure how I can do it in javascript. How do I apply it?   
 
 < P> Do not enter names in just a hidden input field. Change the value with whatever JavaScript you choose, in general, when the form is posted back, then you can tie the value of the name in the administrator's action. And the model name server-side can be set.  
 The effort you are making is unnecessarily complex.  
 If you really want to do this - That's a complete input Submit the JSON string Od. Then bind in JSON as a string in the controller action and Diserilaijh the server-side to store then your model.

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...
