Truncate text

[Maddy]

Hi Folks,

Good evening,

I used the code which i print below,

Yes i got the result , but i need the result like this "TruncateHtml is jus....(continued)"

some_html = '<ul><li><a href="http://whatever">TruncateHtml is just like the vanilla truncate rails helper , TruncateHtml is just like the vanilla truncate rails helper</a></li></ul>'

truncate_html(some_html, :length => 15, :omission => '...(continued)')
  => <ul><li><a href="http://whatever">This...(continued)</a></li></ul>

please advice.

Hi dude,

I think you did wrong by truncating then html. Besides, when you use ':omission' option, the computed length take in consideration the length of '...(continued)'. The best way to do this would be to create a helper method like truncate_text

truncate_text(text, length, end_text)
  end_text ||= ''  # end_text as an optional parameter
  new_text = truncate(text, :length => length) 
  new_text = new_text + end_text
  new_text
end

And then use it in you r html like this:

 some_text = "TruncateHtml is just like the vanilla truncate rails helper , TruncateHtml is just like the vanilla truncate rails helper" 

<ul><li><a href='#'><%= truncate_text(some_text, 15, (continued)) %></a></li></ul>

Good luck

Hi dude,

Good Day,

My some_text content like this = "<p>TruncateHtml is just like the <strong>vanilla truncate <strong>rails helper , TruncateHtml is just like the vanilla truncate rails helper<p>"

As you said i pasted helper code in my pp_helper.rd and in my view,

app_helper.rb

def 

truncate_text(text, length, end_text) end_text ||= '' # end_text as an optional parameter new_text = truncate(text, :length => length) new_text = new_text + end_text new_text end

my_view

   - some_text = raw a.content

   = truncate_text(some_text, 15)

I got an error

wrong number of arguments (2 for 3)

Extracted source (around line #147):

144:           = raw a.name
145:       .ra
146:         - some_text = a.content
147:         = truncate_text(some_text, 15)
148:       .con12 
149:         = "read more.."
150:         .alert_msg

Please advice.

How many arguments has this method got?

How many arguments are you passing?

I wonder what that means. The clue may be in the error message.
