Rails 3: How to display properly text from “textarea”?

∥☆過路亽.° 提交于 2019-12-03 04:08:40
问题 In my Rails 3 application I use textarea to let users to write a new message in a forum. However, when the message is displayed, all newlines look like spaces (there is no <br /> ). Maybe there are other mismatch examples, I don't know yet. I wonder what is the most appropriate way to deal with this. I guess that the text that is stored in the database is OK (I see for example that < is converted to < ), so the main problem is the presentation. Are there build-in helper methods in Rails for

I've found a couple resources for how to place the cursor in a textarea at the end of the text, but I can't sort out a simple way to make it appear at the beginning.

Once again I am here because I have exhausted my research on the subject. I have a very simple setup with very simple markup and yet a very strange behavior. The behavior is eerily similar to ( Firefox and Angular: Textarea placeholder doesn't appear until first focus ) but I am experiencing it in a different environment.

This brings bad a list of comments, where 2-3 fit on the screen before having to scroll for some more already loaded comments. <div class="row"> <div class="col-xs-2 text-right font-sm-dark" style="height:20px; line-height:20px;

I am trying to implement Autocomplete in a text area (similar to http://www.pengoworks.com/workshop/jquery/autocomplete.htm ). What I am trying to do is when a user enters a specific set of characters (say insert:) they will get an AJAX filled div with possible selectable matches.

Thanks, -M You can get the caret using document.selection.createRange(), and then examining it to reveal all the
