jquery - Animate textarea height makes text shake? -


I animated a text field to increase the height and rows on a button click. However during the animation the text moves the text of the field up and down and once the animation is over, it is taken slightly up once, how can I stop it?

This is my code:

thanks :) 

  function morespace () {var thetxt = document.getElementById (. 'And more') value; Var box = document.forms ["myForm"] ["comment"]; If (box. Rows == 3) {$ ("#memail"). Fadeaut (200); $ ('# Comment'). Chetan ({'height': '+ = 235'}, 400, "swing"); Box.rows = 17; Document.getElementById ('more'). InnerHTML = "less space?"; } And {$ ('# comment'). Chetan ({'height': '- = 235'}, 400, "swing"); $ ("# Emailme") fadein (800). Box.rows = 3; Document.getElementById ('more'). InnerHTML = "more space?"; }}   
  & lt; A href = "javascript: morespace ();" Id = "more" & gt; More space? & Lt; / A & gt;   
 Update: You can ask jsfild for jsfild ^ _ ^   
 
 
 The problem is that decimal heights have caused the flicker. I changed it to use a linear development, at the same time, it is equal to the amount of pixels, or many of it (that is because the height is always an integer).  
  function morespace () {Var thetxt = document.getElementById ('more'). Values; Var box = document.forms ["myForm"] ["comment"]; If (box. Rows == 3) {$ ("#memail"). Fadeaut (200); $ ('# Comment'). Chetan ({'height': '+ = 235'}, 235, "linear"); Box.rows = 17; Document.getElementById ('more'). InnerHTML = "less space?"; } And {$ ('# comment'). Chetan ({'height': '- = 235'}, 470, "linear"); $ ("# Emailme") fadein (800). Box.rows = 3; Document.getElementById ('more'). InnerHTML = "more space?"; } }a????   
 We are never able to specify the height of jQuery "x.12343654234"  
 Hope this is acceptable for your needs.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
