javascript - use single hover script for a bunch of buttons, with a variable on mouseover? -

-

I am trying to define a variable on a mouseover event.

The idea is that I later use that variable to replace the DIV ID, and patch a "swap-image" to create a normal mouseover script which I call a group of buttons I can use it for.

So I do not have to use this code again and again and only delete some numbers.

Will this work? I tried to do something like this: 

  // set variable at mouseover $ ("# world_map_8_button"). Mouseover (function () {var location = "# world_map_8";}); // Use mouse in script / mouse over / out swap image + $ (location + "_button"). Hover (function () ($ (location + "_button_jpg"). Attr ("src", "img / buttons / map_buttons / world_map / world_map_8_button_over.jpg");}, function () {$ (location + "_button_jpg") Attr (. "Src", "img / button / map_buttons / world_map / world_map_8_button.jpg");}); });   
 This is some HTML code to help clean things up, all the buttons have been named in the same way.  
  & lt; Div id = "world_map_8_button" & gt; & Lt; Img id = "world_map_8_button_jpg" src = "img / button / map_buttons / world_map / world_map_8_button.jpg" width = "41" height = "41" alt = "" /> & Lt; / Div & gt; & Lt; Div id = "world_map_9_button" & gt; & Lt; Img id = "world_map_9_button_jpg" src = "img / button / map_buttons / world_map / world_map_9_button.jpg" width = "41" height = "41" alt = "" /> & Lt; / Div & gt; & Lt; Div id = "world_map_10_button" & gt; & Lt; Img id = "world_map_10_button_jpg" src = "img / button / map_buttons / world_map / world_map_10_button.jpg" width = "41" height = "41" alt = "" /> & Lt; / Div & gt;   
 If I declare variables in the horrection function, it works (for MaAonnO only), but it does not make any sense and labor will not be saved ...  
  $ ("# world_map_8_button"). Hover (function () {var location = "# world_map_8"; $ ((location + "_button_jpg")). Attr ("src", "img / buttons /map_buttons/world_map/world_map_8_button_over.jpg");}, function ( ) {$ ((Location + "_button_jpg")) attr (. "Src", "img / button / map_buttons / world_map / world_map_8_button.jpg");});    
 
 
 This is a good candidate for CSS. You can have an image in both the hover and the normal picture, and then when the mouse is in the net, set the offset background.  
 To answer your question directly, however, you can try to do something like this:  
  $ ('[id $ = _ button]') . Hover (function () ($ ('#' + this.id + '_gpg') attr ('src', 'img / button / map_buttons / world_map /' + this.id + '_over.jpg') ;. }, Function () {$ ('#' + This.id + '_ jpg'). Attr ('src', 'img / buttons / map_buttons / world_map /' + this.id + '.jpg');} );   
 You only have to keep it on your pages, which will have to be kept in mind without having to do several script and global variables.

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...
