javascript - how is document.form.submit() received in code behind? -


I have document.form1.submit () in javascript. I want to know how it got behind this code. In which class, in which method? something like that. Coz I want to get the value inside a text box to store it in one session. And do I need a real "submit" button for this? It really confuses me.

If I keep it like this: 

  function callSubmit () {var thetext = document.getElementById ('textbox1'). Value; Document.form1.submit (thetext); }   
 Can I be able to pass the value of textbox1 to the code behind a specific method, if so, such as, a received variable? I mean, how can I get the value of textbox 1?  
 By the way, I am trying to do this before landing the page. Because I need to store text from TextBox 1, so that I can allocate the value again after page refresh.   
 
 
 You can get value back to post using 'form' as 'back'.  
  request. Form ["textbox 1"]   
 and if you request this . Read the form  You get all the data from the post  
  Comments . In Asp.net, we usually use the directly  request form.  and we use asp.net controls that handle all ready post values. For example, if you use  asp: textbox  by  id = text box 1  then you can read the post from  textBox1.Text  and if you want to If you want to read it using  Request.Form , you must call  request.form [textbox1.UniqueID]   
  textBox1. UniqueID  is the  name  value on the html control, and the names used for the post.

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...
