div scroll with jquery

Scrollable content area is looking more beautiful when we add some jquery events on it, beside this it will possible throught javascript as well, to make two functions that will call on the mouseover and the mouseout html attributes. But in this example we make it more easy with the help of .hover() event represented by jquery. You will found more about the .hover() event on the jquery official website.

#container{
 width: 500px;
 height: 200px;
 overflow: hidden;
 margin: 0 auto;
 padding: 3px;
 border: 2px solid #42826C;
 background: #A5C77F;
}
p{
 font: 13px/18px Verdana, Arial, Helvetica, sans-serif;
 padding-right:20px;
}

Here is the html part:

        
  
Enter the text here as much as you want. 
 

Now here is the jquery file:

$(function(){
 
 $('#container').hover(
  function(){
   $(this).css({'overflow':'auto'});
  },
  function(){
   $(this).css({'overflow':'hidden'});
  });
});

submit form without page refreshing using jquery, ajax and php

Ajax request is the most powerful feature of jquery, it helps to send data over the cross domain in the backend. In this post i give the very basic idea to submit a form with page refreshing and get the result. In this script i use some basic jquery and php. If you will apply this script in your own page then, I request you to validate all the data. Lets beautify the form with some CSS codes:

label{
 font: 13px/18px Verdana, Arial, Helvetica, sans-serif;
 color: #666666;
}
.inpbox{
 border: 1px solid #999999;
 padding: 2px;
 height:20px;
}
.txtbox{
 border: 1px solid #999999;
 padding: 2px;
 resize: none;
}
.buttn{
 border: 1px solid #999999;
 font: bold 13px/18px Verdana, Arial, Helvetica, sans-serif;
 color: #666666;
 padding: 3px 10px;
}

Here is the basic form layout:

  
   
     

      

     
     

    
Name :
    

     
     

    
Email :
    

     
     

    
Subject :
    

     
     

    
Query :
    

     
     

    
 
    

     
   
  
 

I use table to prevent the browser confliction bug. Now lets start with some jquery stuff, before applying this stuff please insert the jquery source file from jquery official site or form ajax google api.

$('input[name="send"]').click(function(){
  var query = $('#myform').serialize();
  
  $.ajax({
   url: 'ajaxForm.php',
   data: query,
   success: function(data){
      if(data == 'send'){
       $('.result').html('Data Send Successfully!');
       
       $('input[name="name"]').val('');
       $('input[name="email"]').val('');
       $('input[name="subject"]').val('');
       $('textarea[name="query"]').val('');
      }
      else{
       $('.result').html('Error to Send Data!');
      }
     }
  });
 });

Now as you see in the above jquery codes that i request the a ajaxForm.php page through ajax request which handles all the data and return the result.

 $name = (isset($_REQUEST['name'])) ? $_REQUEST['name'] : NULL;
 $email = (isset($_REQUEST['email'])) ? $_REQUEST['email'] : NULL;
 $subject = (isset($_REQUEST['subject'])) ? $_REQUEST['subject'] : NULL;
 $query = (isset($_REQUEST['query'])) ? $_REQUEST['query'] : NULL;
 
 if( !empty($name) && !empty($email) && !empty($subject) && !empty($query) ){
  echo 'send';
 }
