JavaScript function in href vs. onclick



bad:
 id="myLink" href="javascript:MyFunction();">link text
good:
 id="myLink" href="#" onclick="MyFunction();">link text
better:
 id="myLink" href="#" onclick="MyFunction();return false;">link text
even better 1:
 id="myLink" title="Click to do something" href="#" onclick="MyFunction();return false;">link text
even better 2:
 id="myLink" title="Click to do something" href="PleaseEnableJavascript.html" onclick="MyFunction();return false;">link text
Why better? because return false will prevent browser from following the link
best:
Use jQuery or other similar framework to attach onclick handler by element's ID.
$('#myLink').click(function(){ MyFunction(); return false; });
$('a').click( function() { your_code_here; return false; } );




 id="link" href="http://example.com/action">link text

ExtJS 4 with Spring MVC Example

Introduction When developing a brand new application for the company I work for, one of the first thing I implement is "authentication". Not only is this process generally a prerequisite to access many other functions but it is also very simple and covers every layer of an application, from GUI to the database. So instead of another minimalistic "Hello World" tutorial, here is a "Login/Password" example, using 2 famous technologies : Spring MVC and ExtJS 4.   Prerequisites Because this tutorial is quite long, I won't go into the details of each technology I used but I will mainly focus on how ExtJS and Spring can be nicely used together.

Filtering by single field: store . filter ( "email" , /\.com$/ );   Using multiple filters: store . filter ([ { property : "email" , value : /\.com$/ }, { filterFn : function ( item ) { return item . get ( "age" ) > 10 ; }} ]);   Using  Ext.util.Filter  instances instead of config objects (note that we need to specify the root config option in this case): store . filter ([ Ext . create ( ' Ext.util.Filter ' , {   property : "email" , value : /\.com$/ , root : 'data' }),   Ext . create ( ' Ext.util.Filter ' , {   filterFn : function ( item ) {   return item . get ( ...
