javascript - Change the image of a JSF commandbutton with DHTML event onmouseover -

-

I want to change the image of my button when the mouse goes over it.

I can do this for DHTV Event OnMoverOver, but how?

Do I still need to make javascript for this?

What should I do to make this work?

This is my current code: 

  & lt; H: commandButton class = "btn" image = "/ resources / images / mainbtn1.png" onmouseover = "/ resources / images / Mainbtn2.png" / "& gt;    < P> 
 
 this  & lt; h: commandButton Image = "foo.png" & gt;  one HTML  Lt; input type = "image" src = "foo.png" & gt; .  onmouseover  attribute (such as all the  *  as attributes ) Javascript should point to the functions, however, you are putting image path in there area. This only causes a javascript error (which you may have seen if  
 You have to write some JS which changes  src  E the attribute of the image button accordingly:  
 < Do not forget to add code> onmouseover = "this.src = '/ resources / images / mainbtn2.png'"   
 don ''  onmouseout  which changes the image back  
 
  Impossible  In a solid problem, use the general practice CSS background, for this, the picture is HTML  & lt; Input type = "picture" & gt;  Technology is a completely different purpose, it represents an image map that allows you to send coordinates of the mouse where you clicked in the image map. You obviously are not interested in this information because you are not using a static image.  
 Example  
  & lt; H: value of the command button = "" style class = "mybutton" />   
 which generates  
  & lt; Input type = "submit" value = "" class = "mybutton" />   
 and add this CSS (kickoff example)  
  .mybutton {margin: 2px; Padding: 0; Border: 0; Width: 100px; Height: 20px; Background-image: url ('foo.png'); Cursor: indicator; Overflow: visible; } .mybutton: hover {background-image: url ('bar.png'); }   
 This is not only good reusable / maintainable, but also does not require JS support.

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...
