How to get text of an input text box during onKeyPress?

Question

I am trying to get the text in a text box as the user types in it (jsfiddle playground):

Answer 1

By using event.key we can get values prior entry into HTML Input Text Box. Here is the code.

function checkText()
{
  console.log("Value Entered which was prevented was - " + event.key);
  
  //Following will prevent displaying value on textbox
  //You need to use your validation functions here and return value true or false.
  return false;
}
