When user click on browser back button, user will see a alert message for that I am using below code. 

 window.onbeforeunload = function () { return "If you want to go back to previous page Please use Previous step Button in below"; };

But in the code I have written "If you want to go back to previous page Please use Previous Step Button in below". This message is not displaying in alert box,instead of that message it is showing another message:

please click here.

How can I display my own message in the alert box?

You will need to put javascript/jquery code you want to use on a handler for beforeunload event

window.addEventListener("beforeunload", function (event) {
  //your code goes here. Create modal window or whatever you need

});
