Accesing jQuery from Controller - El Forum - 08-09-2009

[eluser]riko0na[/eluser]
I am using ajax to view the display made from the controller by getting data from the database like this also I use jQuery for the Date(I've showed only this part)

VIEW:
Code:
<head>

<link type="text/css" href="uicore/development-bundle/themes/base/ui.datepicker.css" rel="stylesheet" />

<scr1pt type="text/javascr1pt" src="css/jquery-1.3.2.js"></scr1pt>
<scr1pt type="text/javascr1pt" src="js/ui.core.js"></scr1pt>
<scr1pt type="text/javascr1pt" src="js/ui.datepicker.js"></scr1pt>

$(function() {
    $('#catdatev').datepicker({
        changeMonth: true,
        changeYear: true
       });
    });

<scr1pt type="text/javascr1pt">
    function edCat( strURL )
    {
       var xmlHttpReq = false;
       var self = this;
       var cname = document.edc.catnameed.value;
        if(cname == "")
        {
         cname = "noblanks";
        }
self.xmlHttpReq.open( 'GET', strURL + cname, true );
self.xmlHttpReq.setRequestHeader( 'Content-Type', 'application/x-www-form-urlencoded' );
self.xmlHttpReq.onreadystatechange = function()
{
if (self.xmlHttpReq.readyState == 4)
{    
   document.getElementById( "showeditdel" ).iinnerHTML = self.xmlHttpReq.responseText;
}
else
{
   document.getElementById( "showeditdel" ).iinnerHTML = '<center><img src="images\/ajax-loader.gif"/><\/center>';
}
}
self.xmlHttpReq.send( null );
}
</scr1pt>
&lt;/head&gt;

&lt;body&gt;

<A oonclick="edCat('admincms/edcategory/');" class="ui-state-default ui-corner-all" style="text-decoration: none; cursor: pointer;">View</A>

&lt;/body&gt;

CONTROLLER:
Code:
function edcategory($cname)
{
  echo 'End Date: &lt;input type=text name=enddate id=catdatev value='.$date.'&gt;'
}

my question is, can I call the jQuery function from the controller with this code? newbie here. . cause it works fine when i call the jQuery function from the view page..also the call from the ajax to controller works fine also,, confuse here :-S

You cannot call jQuery functions (or any JavaScript) from a server-side language like PHP. PHP (and therefore CodeIgniter) does all its work on the server, JavaScript does all its work on the client-side (the users browser) so the interaction between the two goes like this:

1.) CodeIgniter (PHP) works out which controller and which method to use, which then picks a view file.
2.) A view file includes all sorts of HTML, images, CSS, JavaScript, Flash, etc.
3.) jQuery (JavaScript) can then call another CodeIgniter page via AJAX to get a response in a similar way.

And repeat.

Evaluate the response accordingly and it will work.

Have a look here, MALSUP has a neat library which allow you to handle any response. You can have javascript no problem! Good luck

Phil Sturgeon and jcavard, thank you for your replies.. I've finally got my problem answered just call the jquery again if the codeigniter page response via AJAX contains a jQuery call function..
