Solution 1:

From comments below your question:

no im not using any plugin

So that is the problem. I guess you just pasted some code from somewhere and did not look at the dependencies.

Your code works if the jQuery-Confirm plugin is loaded. So just add the CDNs used in the below snippet.

functionchecknag() {
  var x1 = document.getElementById('tsumnag').value;
  var x2 = document.getElementById('salenugsum').value;
  if (+x1 == +x2) {
    $.alert({
      title: 'Alert!',
      content: 'Please enter item name',
      onDestroy: function() {
        // here the button key 'hey' will be used as the text.
        $('#munshi_perc').focus();
      }
    });
    returnfalse;
  }
}
