javascript - unable to send ajax request on php -


I am using an AJAX request to send to php. In the form method, I am using the following code.

rohit1.php 

  & lt; Form action = "index1.php" onsubmit = "callfunc ()" & gt; & Lt; Span id = "raj" & gt; & Lt; / Span & gt; & Lt; Input type = "submit" value = "submit" & gt; & Lt; / Div & gt; & Lt; / Form & gt;   
 In JavaScript, I am using: callfun.js  
  function callfunc () {var http = new XMLHttpRequest (); Var Name = Prompt ('Enter the name of the form'); Var Name = "Rohit"; Var url = "index1.php"; Var s = document.getElementById ('raj'). InnerHTML; Warning (http); Http.open ("POST", "index1.php? Name =" + name, true); Http.onreadystatechange = function {if (http.readyState == 4 & amp; http.status == 200} {}} http.send ();}   
 When I Function, then submitting it is redirecting to index.php? Label = on the name of index.php? Name = what should I do for it ???   
 
 
 just try to add  return false  at the end of the  callfunk ()  function. Will stop the default event and will not function as a standard form.  < / Div>

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.
