Passing data to the Server

Many times you collect input from the user and you pass that input to the server for further processing. JQuery AJAX made it easy enough to pass collected data to the server using data parameter of any available Ajax method.

Example:

This example demonstrate how can pass user input to a web server script which would send the same result back and we would print it:

<html>
<head>
<title>the title</title>
   <script type="text/javascript" 
   src="/jquery/jquery-1.3.2.min.js"></script>
   <script type="text/javascript" language="javascript">
   $(document).ready(function() {
      $("#driver").click(function(event){
          var name = $("#name").val();
          $("#stage").load('/jquery/result.php', {"name":name} );
      });
   });
   </script>
</head>
<body>
   <p>Enter your name and click on the button:</p>
   <input type="input" id="name" size="40" /><br />
   <div id="stage" style="background-color:blue;">
          STAGE
   </div>
   <input type="button" id="driver" value="Show Result" />
</body>
</html>

Here is the code written in result.php script:

<?php
if( $_REQUEST["name"] )
{
   $name = $_REQUEST['name'];
   echo "Welcome ". $name;
}
?>

Now you can enter any text in the given input box and then click "Show Result" button to see what you have entered in the input box.

HTTP Status Code 501 - Not Implemented

501 Error Code Explained The server either does not recognise the request method, or it lacks the ability to fulfill the request. Why it occurs The error occurs when the Web server does not understand or does not support the HTTP method it finds in the HTTP data stream sent to it by the client. The method in the request HTTP data stream should be one of the following GET, OPTIONS, HEAD, POST, PUT, DELETE, TRACE and CONNECT as defined by the HTTP protocol Or the method may be valid but not actually supported by the Web server. Fixing 501 error code The client should specify a valid request type. Even after that if the Web server is responding incorrectly, then the web server simply needs to be upgraded to fix the issue. If you are registered with 100pulse, your site will be monitored and you will be intimated by an email or a short message service when 501 status code error occurs.

Optimize MySQL query with STRAIGHT_JOIN

Before finalizing my queries, I use MySQL Workbench to explain it to make sure the performance is good. I always notice that the performance of the queries with joins on multiple tables varies at times. Then I start indexing my tables to make sure that the Explain is happy and scanning minimum records before handing over the data. But with one of my query, even after adding an appropriate index I was not getting the performance I was expecting. I asked Workbench to explain the query and what? MySQL was not using my newly added index which could optimize the query. I tried FORCE INDEX and MySQL liked it. It started using the index which I forced it to. But I was not happy at forcing MySQL to use my index. I wanted it to do it itself. After researching a bit, I came across STRAIGHT_JOIN and without wasting any time, I added it to my query and what? MySQL started using my index without being forced to. Now the question was, how the STRAIGHT_JOIN works and is different from INNER JOIN. Wit

In Java, what’s the difference between method overloading and method overriding?

The difference between overriding and overloading in Java is a common source of confusion – but it is fairly simple to understand. Let’s start the discussion by talking more about method overloading. Overloading in Java can occur when two or more methods in the same class share the same name or even if a child class shares a method with the same name as one of it’s parent classes. But, in order to actually have overloaded methods, the methods not only have to have the same name, but there are other conditions that must be satisfied – read below to see what those conditions are. Suppose we have a class called TestClass which has 2 methods, and both methods have the same name – let’s say that name is “someMethod” – this would be considered to be method overloading if at least one of these 2 things is true: 1.) The number of parameters is different for the methods 2.) The parameter types are different. How to NOT overload methods: It’s important to underst
