Replace double space with in javascript

Hello Guys,

        Last time when i was playing with double spaces.. found the interesting thing. When passing the double space string from javascript (view) to controller , it converts the valid space to non-breaking space.

Lets see the eg.

View: index.rhtml

a = "This  is the pen"

a.gsub("  ", " &nsbsp;")

<script language='javascript/text'>

 

  /* Now assign the value to input element by */

  $('txtid').value = <%= a %>;

 // Get value back encodeURIComponent($('txtid'))

</script>
 

at controller

def any_method

   # replace '\xC2\xA0' or '&nbsp;' with ' '

   params[:a].gsub("\xC2\xA0", " ").gsub("&nbsp;", " ")

end

Hope above article is helpful to you guys.
