Question

How can i make the function for this button:

<input id="btntest" type="button" value="Check" onclick="return btntest_onclick()" />

so that after 30 click's redirects me to a different page.

Answer 1

Declare a global variable:

var counter = 0;

function btn_test_onclick(){
    if(counter === 30){
        window.location.href = 'http://www.google.com';
    } else {
       counter++;
    }
}

Here's some info on window.location

Answer 2

     <script>
         var count = 0;
        function btntest_onclick(){
            count++;
            if(count ==12){
               window.location.href = 'http://www.google.com';
            }
        }
    </script>

Answer 3

You can do like this

<input id="btntest" type="button" value="Check" onclick="return btntest_onclick()" />


<script>

var btntest_onclick = (function () {
    var i = 1;

    return function () {
      alert(i);
       i++;
        if(i>30){
           window.location = "www.google.com";
          }
    }
})();
</script>
