To start, you will need to set up an event listener for key presses. If you are utilizing JQuery, there is a function called $.keydown() that can aid in this process. Specifically, you will want to monitor for space bar presses as shown below:
var lastWord = '';
$('textarea').keydown(function(e) {
if (e.keydown == 32) {
//perform actions with the last word typed
lastWord = '';
} else {
var content = $(this).value;
lastWord.concat(content.slice(0,-1)); //grabbing the last letter in textarea
}
})
