Getting key/value pair from JSON object and getting variable name and value from JavaScript object.

Hi, I had faced one issue like this. I have an JSON object but I don't know any key name but I need to get the all the key and corresponding value from JSON object using client side JavaScript. Suddenly I wondered whether it's possible or not, after that I had done lot of workaround and finally got this solution. See the below example. function getKeyValueFromJSON() { var jsonObj = {a:10,b:20,c:30,d:50} ; for ( var key in jsonObj) { alert( "Key: " + key + " value: " + jsonObj[key]); } } In this example I have created the one json array as string, and converted this string into JSON object using eval() function. Using for-each loop I got all the key value from jsonObj, and finally using that key I got the corresponding value. Finally I got the alert like this, Key: a value:10 Key: b value:20 Key: c value:30 Key: d value:50 During this workaround I got one more idea, using this same way I got

Simple Login Application Using Spring MVC and Hibernate – Part 1

I hope developers working in web application development might hear about MVC architecture. Almost all technologies provide support for MVC based web application development, but the success is based on many factors like reusable of the code, maintenance of the code, future adaption of the code, etc.., The success of the Spring MVC is “ Open for extension and closed for modification ” principle. Using Spring MVC the developers can easily develop MVC based web application. We don’t need any steep learning curve at the same time we need to know the basics of spring framework and MVC architecture. The Spring MVC consists of following important components. 1. Dispatcher servlet 2. Controller 3. View Resolver 4. Model Spring MVC - Overview The overall architecture of Spring MVC is shown here. 1. When “Dispatcher Servlet” gets any request from client, it finds the corresponding mapped controller for the request and just dispatches the request to the corresponding contro

Java Vs Groovy - Enum Demo

Java 5 introduced enum that solve the problem with enumeration. Groovy also support that feature, as shown here. Enum example using Java. enum ShirtSize { SMALL,MEDIUM,LARGE,EXTRALARGE } class ShirtImplementation { public void orderShirt(ShirtSize size) { switch(size) { case SMALL : System.out.println("The size of the shirt is small"); break; case MEDIUM : System.out.println("The size of the shirt is medium"); break; case LARGE : System.out.println("The size of the shirt is large"); break; case EXTRALARGE : System.out.println("The size of the shirt is extra large"); break; default : System.out.println("The shirt size is not available"); break; } } } public class EnumExample { public static void main(String args[]) { ShirtImplementation shirtImplementation = new ShirtImplementation(); shirtImplementation.orderShirt(ShirtSize.SMALL); shirtImplementation.o
