If your button is default  button  make sure you explicity set the type attribute  otherwise the WebForm will treat it as submit by default   if you use js do like this   lt form method  POST  gt      lt button name  data   type  button  id  btnData  onclick  getData    gt Click lt  button gt   lt  form gt      If you use jquery use like this      lt form method  POST  gt      lt button name  data   type  button  id  btnData  gt Click lt  button gt   lt  form gt          btnData   click function e      e preventDefault          Code goes here getData       your onclick function call here

All you need to do is put a type tag and make the type button    x000D   x000D   lt button id  btnId  type  button  gt Hide Show lt  button gt  x000D   x000D   x000D    That solves the issue

A javascript method to disable the button itself  document getElementById  ID NAME   disabled   true    Once all form fields have satisfied your criteria  you can re-enable the button  Using a Jquery will be something like this       ID NAME    prop   disabled   true

lt form method  POST  gt       lt button name  data  onclick  getData    gt Click lt  button gt   lt  form gt    instead of using button tag  use input tag  Like this    lt form method  POST  gt       lt input type    button  name  data  onclick  getData    value  Click  gt   lt  form gt

Add type  button  to the button    lt button name  data  type  button  onclick  getData    gt Click lt  button gt    The default value of type for a button is submit  which self posts the form in your case and makes it look like a refresh

You can use ajax and jquery to solve this problem    lt script gt      function getData               ajax               url     urlpattern               type    post               success   function data                    alert  success                                      lt  script gt   lt form method  POST  gt       lt button name  data  type  button  onclick  getData    gt Click lt  button gt   lt  form gt

For any reason in Firefox even though I have return false  and myform preventDefault    in the function  it refreshes the page after function runs  And I don t know if this is a good practice  but it works for me  I insert javascript this preventDefault    in the action attribute    As I said  I tried all the other suggestions and they work fine in all browsers but Firefox  if you have the same issue  try adding the prevent event in the action attribute either javascript return false  or javascript this preventDefault     Do not try with javascript void 0   which will break your code  Don t ask me why  -    I don t think this is an elegant way to do it  but in my case I had no other choice   Update   If you received an error    after ajax is processed  then remove the attribute action and in the onsubmit attribute  execute your function followed by the false return   onsubmit  functionToRun    return false    I don t know why all this trouble with Firefox  but hope this works

The problem is that it triggers the form submission  If you make the getData function return false then it should stop the form from submitting    Alternatively  you could also use the preventDefault method of the event object   function getData e        e preventDefault
