// In your view:



<%= date_select('range', 'start_date', :order => [:month, :day, :year])%>

// In your controller:



@start_date = Date.civil(params[:range][:"start_date(1i)"].to_i,params[:range][:"start_date(2i)"].to_i,params[:range][:"start_date(3i)"].to_i)

Javascript code to set Rails date_select to today.

mrblack (Andy) — Wed, 13 Dec 2006 20:45:28 GMT

If you are using date_select in rails here is a little bit of javascript so that at the side of the fields the user can click a link that will automatically set the fields to todays date.

Updated: Now works on rails 1.2, as date_select now finally has ids



# put is app_root/public/javascript/application.js



function set_today(model, atrib)

{

    t3 = document.getElementById(model + '_' + atrib + '_3i');

    var dt = new Date(); 

    t3.selectedIndex = dt.getDate();

	

    t2 = document.getElementById(model + '_' + atrib + '_2i')

    t2.selectedIndex = dt.getMonth() + 1;

    

    t1 = document.getElementById(model + '_' + atrib + '_1i')



    for (i = 0; i < t1.length; i++)

	       {

	           if (t1.options[i].text == dt.getFullYear())

	           {

	               t1.selectedIndex = i;

	          }

    } 

}

To call this method say in a link use this in your rhtml



today?
