Satisfaction II – javascript field focus

I Happiness to share

You know when users gotta insert a lot of records into the DB, it is cool if the programmer always set the first field of a Form with focus! Or else they could get really annoyed..

First of all, this is a Rails solution but can be done in any other language.. if you know what page your user is visiting..

snippet..

	function start_up(){
<% if controller.action_name == 'criar' -%>
		(document.forms[0])[1].focus();
<% elsif controller.action_name == 'alterar' -%>
		(document.forms[0])[2].focus();
<% end -%>
return true;
 }

then call the function on BODY onload= ’start_up’

This if elsif is required because in Rails a ‘new’ form have 1 hidden field and a ‘edit’ form have 2 hidden fields, if your form is in PHP C# and have no hidden fields, you are likely to use (document.forms[0])[0].focus(); for the very first field on the very first form.

Conclusion:
So COOL !! This function becomes something different depending on the page the user is visiting

Sorry the syntax is messed up is because of word press post security is kinda paranoid..
