how to resize text area
Added by Vigeous List over 13 years ago
Hello,
I am trying to resize the text area in the app/views/wiki/edit.rhtml file.
this line:
<%= f.text_area_tag :reason, :nil :size =>'5x15', :class => 'wiki-edit', :accesskey => accesskey(:edit) %>
What I am tryint to get is that, if I enter only one line, the rows of the text area should be 1, and if I enter 10 (or n rows) lines of text, the text area should grow (every second) to 10 (or n rows) rows.
Similar solution is used in trac with jQuery:
<script type="text/javascript"> jQuery(document).ready(function($) { $("#text").blur(function() { $("#scroll_bar_pos").val(this.scrollTop); }).get(0).scrollTop = $("#scroll_bar_pos").val(); $("#editrows").change(function() { resizeTextArea("text", this.options[this.selectedIndex].value); }); function autoResizeText() { var preview_height = $("#preview").height(); if (preview_height) $("#text").height(preview_height); } autoResizeText(); $(window).resize(autoResizeText); $("#text").autoPreview("/trac/ecom/wiki_render", { realm: "wiki", id: "Shops" }, function(textarea, text, rendered) { $("#preview div.wikipage").html(rendered); autoResizeText(); }); }); </script>
Could someone help me to adapt the script to my text area, please?
Thank you,
Vige

Redmine uses prototype, not jquery, so you'd have to look for something similar for prototype.
