How to get alert message on second click of a button

I would like to know that how can I get an alert message on second click of a button, not on a first click.

ex: <input type="button" value="Message" onclick="showMessage()">

function showMessage(){
    alert("It's a second click message"); // this alert message should be shown on second click of a button
}

Consider this code, This is alert message after every alternate click:

var count = 1;

function showMessage() {
  if (!(count++ % 2))
    alert("It's a second click message"); //this alert message at every second click
}
<input type="button" value="Message" onclick="showMessage()" />

Use counter instead..

var count = 0; //global variable
function showMessage() {
  if (count++ == 1) { //Compare and then increment counter
    alert("It's a second click message"); //this alert message will be shown only on second click of a button
  }
}
<input type="button" value="Message" onclick="showMessage()">

If you are not looking for the dbclick event, then you can use a flag to check whether it is the second click to show the alert

var flag;

function showMessage() {
  if (flag) {
    alert("It's a second click message"); // this alert message should be shown on second click of a button
  } else {
    flag = true;
  }
}
<input type="button" value="Message" onclick="showMessage()">
