I want to write a simple Client-side Application that will send a following request to Google
http://www.google.com/dictionary/json?callback=a&sl=en&tl=en&q=Hello
If you directly click on this link you will get a Json for downloading.
What I want to achieve here is that I will have a textbox and a button, when user enters something in the textbox and click on the button I will prepare the above url and get the json which I will parse and display in a paragraph on my web page.
I am relatively new to this WebAPI stuff but I know JavaScript. So can anyone tell me what is the better way to achieve this and do I need to create a OAuth (Authorization) for this.
