Hello Shariq,
Add a check when the button is clicked to see if there is any text. If there isn't, pop up an alert box (or some other form of feedback) to tell the user to enter data, and don't do the button functionality.
<input id="myText" type="text" onkeyup="stoppedTyping()">
<input type="button" value="Click to begin!" id="start_button" onclick="verify()" disabled/><script type="text/javascript">
function stoppedTyping(){
if(this.value.length > 0) {
document.getElementById('start_button').disabled = false;
} else {
document.getElementById('start_button').disabled = true;
}
}
function verify(){
if myText is empty{
alert "Put some text in there!"
return
}
else{
do button functionality
}
}
</script>-
