Lets say you have an HTML line like that
code <div id="myDiv">Hello World<&#47;div> /code
which result is: Hello World

And now you want to change it to : Hello Europe

In a nutchel use this code : code$('#myDiv')&#46;text("Hello Europe");/code

Explanation
1)Select your div tag with myDiv id ,using jQuery
code$('#myDiv')/code
2)change text of the tag, usign jQuery.
code&#46;text("Hello Europe")/code

Now if you want that to happen when the user press a button you have to add an eventClickRun Javascript
Copy-Paste your code
