Hope this works for you.

 $(document).ready(function(){ $('#your_form').submit(function(event) { event.preventDefault(); dataString = $("#your_form").serialize(); $.ajax({ type: "post", url: "post.php", dataType:"json", data: dataString, success: function (response) { if(response.status === "success") { // do something with response.message or whatever other data on success alert("Data Uploaded: "); window.location='home.html'; } else if(response.status === "error") { alert("Please close the previous issue"); window.location='home.html'; } } }) return false; });
