Hi, experts
I would like to create a simple text link that kicks off javascript by 
onmouseover, but avoid to do submit() or go to another webpage, and I 
also need to  show the data stored in my backing bean.
The Html line could be like the following.  I played with both 
outputLink/outoutCommand, but it alway tries to display webpage or 
submit a new request by "clicking" or onclick.  I would like to disable 
to submit for commandLink/outputLink for onclick.  How could I do it ?   
Or is there any other method other than outputLink/commandLink that can 
avoid submit()/going to another page ?

<a href="_blank" onmouseover="doPopupMolWeight();" 
onmouseout="close_window_mol();" > 
'NeedToDisplayDataStoredInBackingBeanHere' </a>

I tried something like the following with outputLink, but it submits a 
request to the server when I click the link after executing "javascript 
doNothing()".
<h:outputLink value="#{value}" onclick="doNothing()" 
onmouseover="doPopupMolWeight();" onmouseout="close_window_mol();"  />
<h:commandLink value="#{value}" onclick="doNothing()" 
onmouseover="doPopupMolWeight();" onmouseout="close_window_mol();"  />

As with any Javascript event handler, you need to return false if you 
want to prevent the default action from taking place. Add a 'return 
false;' at the end of your doNothing() function [or, since that function 
presumably doesn't do anything, you could just replace it with the 
return in the onclick attribute.]
