javascript - remove value from the list -

-

I have a list of checkboxes When I click on each checkbox I am adding value to the hidden variable. But the question is whether I want to remove the value from the list when I uncheck the checkbox. How this slice cab is done

There is a hidden form variable 

    
 and jquery  
  $ (". MyCheckboxClass"). Change (function () {var output = 0; $ (". MyCheckboxClass") (Outlook = "," + $ (this) .val ();} and {output = $ .grep (output, function (value) { Return value! = $ (This) .val ();})}} $ ("# idlist"). Val (output);});});    
 
 
 Something like this: (demo)  
 We use it To store the object, add and remove the  vals  objects as check / uncheck.  
  var vals = {}; $ ('Input [type = checkbox]'). Click (function () {var that = $ (this); if (that.is (': checked')) {console.log (this.name); vals [this.name] = "in your object"; } And {delete vals [this.name];} console.log (vals);});

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...

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...
