javascript - JQuery plugin scope problems -

-

I feel a little ignorant, but I think some education will not hurt me.

I have simplified my code to outline the problem - the problem is that when Fu () is said from within the init method, it is believed that the Worldwide, A, B Can not use C and settings. These laws are defined outside the field, so why are they not reachable?

For example, the settings are clearly defined before the foo call, so why not see the foo setting? 

  (function (jquery) {a = new date (); var b; var c = 1; settings = 0; // here or not - same issue var methods = {init: function (Settings) {c = $ (this); settings = jQuery.extend ({id: Math forrest (Math.Random) * 1001), X: 3; etc: 2}, Settings || {}); M = 1; af ();}}; function fu () {x = settings.x; / / settings var n = cm; return x;} jQuery.fn.bar = function (method) {if (methods [method]) // If we have a method that is {return methods [method]. Aply (this, Array.prototype.slice.call (argument, 1));} and if (method of type === 'object' || ! Method) // Otherwise if we have an object (settings) Or nothing, then init. {Return methods.init.apply (; this, argument);} and ($ .error ('method' + method + 'does not exist'); // otherwise we have There is an error.}};});   
 Any thoughts?   
 
 
 You are creating a local copy settings when you define it as the argument of your init function:  
  // Here is a global setting init: function ( Settings) {// here is a local setting // changes have been made   
 So when Foo is called setting 0 is still, and you are reaching  number (0) .x  which is Is undefined.  
 Simply deleting the local copy of the settings will solve your problem:  
  init: function (s) {  
 and replace  Settings || {}  to  s || {}

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. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment. Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

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...
