Resetting a multi-stage form with jQuery

Question

I have a form with a standard reset button coded thusly    lt input type  reset  class  button standard  value  Clear    gt    Trouble is  said form is of the multi-stage sort  so if a user fills out a stage  amp  then returns later  the  remembered  values for the various fields won t reset when the Clear button is clicked   I m thinking that attaching a jQuery function to loop over all the fields and clear them  manually  would do the trick  I m already using jQuery within the form  but am only just getting up to speed  amp  so am not sure how to go about this  other than individually referencing each field by ID  which doesn t seem very efficient   TIA for any help

Simply use the jQuery Trigger event like so      form   trigger  reset      This will reset checkboxes  radiobuttons  textboxes  etc    Essentially it turns your form to it s default state  Simply put the  ID  Class  element inside the jQuery selector

Clearing forms is a bit tricky and not as simple as it looks     Suggest you use the jQuery form plugin and use its clearForm or resetForm  functionality  It takes care of most of the corner cases

All these answers are good but the absolute easiest way of doing it is with a fake reset  that is you use a link and a reset button    Just add some CSS to hide your real reset button   input type reset    visibility hidden  height 0  padding 0     And then on your link you add as follows   lt a href  javascript     onclick  reset click    gt Reset form lt  a gt    lt input type  reset  name  reset  id  reset    gt  lt  --This input button is hidden-- gt    Hope this helps  A

jQuery Plugin  I created a jQuery plugin so I can use it easily anywhere I need it   jQuery fn clear   function         var  form     this         form find  input text  input password  input file  textarea   val           form find  select option selected   removeAttr  selected         form find  input checkbox  input radio   removeAttr  checked         return this        So now I can use it by calling       my-form   clear

You might find that this is actually easier solved without jQuery   In regular JavaScript  this is as simple as   document getElementById  frmitem   reset      I try to always remember that while we use jQuery to enhance and speed up our coding  sometimes it isn t actually faster  In those cases  it s often better to use another method

From http   groups google com group jquery-dev msg 2e0b7435a864beea       myform   0  reset      setting myinput val     might not emulate  reset  100  if you have an input like this    lt input name  percent  value  50   gt    Eg calling myinput val     on an input with a default value of 50 would set it to an empty string  whereas calling myform reset   would reset it to its initial value of 50

I was having the same problem and the post of Paolo helped me out  but I needed to adjust one thing  My form with id advancedindexsearch only contained input fields and gets the values from a session  For some reason the following did not work for me       advancedindexsearch   find  input text   val        If I put an alert after this  I saw the values where removed correctly but afterwards they where replaced again  I still don t know how or why but the following line did do the trick for me       advancedindexsearch   find  input text   attr  value

I m just an intermediate in PHP  and a bit lazy to dive into a new language like JQuery  but isn t the following a simple and elegant solution    lt input name  Submit1  type  submit  value  Get free quote    gt   lt input name  submitreset  type  submit  value  Reset    gt    Can t see a reason why not have two submit buttons  just with different purposes   Then simply   if    POST  submitreset     Reset       source    --Choose language from--     target    --Choose language to--       You just redefine your values back to whatever the default is supposed to be

Here is something to get you started     form      match your correct form   find  input type  submit   input type  reset       don t reset submit or reset  val         set their value to blank   Of course  if you have checkboxes radio buttons  you ll need to modify this to include them as well and set  attr   checked   false     edit Paolo s answer is more concise  My answer is more wordy because I did not know about the  input selector  nor did I think about simply removing the checked attribute

A method I used on a fairly large form  50  fields  was to just reload the form with AJAX  basically making a call back to the server and just returning the fields with their default values  This made is much easier than trying to grab each field with JS and then setting it to it s default value  It also allowed to me to keep the default values in one place--the server s code  On this site  there were also some different defaults depending on the settings for the account and therefore I didn t have to worry about sending these to JS  The only small issue I had to deal with were some suggest fields that required initialization after the AJAX call  but not a big deal

I made a slight variation of Francis Lewis  nice solution  What his solution doesn t do is set the drop-down selects to blank   I think when most people want to  clear   they probably want to make all values empty   This one does it with  find  select   prop  selectedIndex   -1      fn clear   function           this  find  input                filter   text   password   file   val                  end                filter   checkbox   radio                    removeAttr  checked                end            end        find  textarea   val              end        find  select   prop  selectedIndex   -1           find  option selected   removeAttr  selected             return this

updated on March 2012  So  two years after I originally answered this question I come back to see that it has pretty much turned into a big mess  I feel it s about time I come back to it and make my answer truly correct since it is the most upvoted   accepted  For the record  Titi s answer is wrong as it is not what the original poster asked for - it is correct that it is possible to reset a form using the native reset   method  but this question is trying to clear a form off of remembered values that would remain in the form if you reset it this way  This is why a  quot manual quot  reset is needed  I assume most people ended up in this question from a Google search and are truly looking for the reset   method  but it does not work for the specific case the OP is talking about  My original answer was this     not correct  use answer below     input    myform    not   button   submit   reset   hidden    val      removeAttr  checked    removeAttr  selected     Which might work for a lot of cases  including for the OP  but as pointed out in the comments and in other answers  will clear radio checkbox elements from any value attributes  A more correct answer  but not perfect  is  function resetForm  form         form find  input text  input password  input file  select  textarea   val           form find  input radio  input checkbox             removeAttr  checked   removeAttr  selected          to call  use  resetForm     myform        by id  recommended resetForm    form name myName         by name  Using the  text   radio  etc  selectors by themselves is considered bad practice by jQuery as they end up evaluating to   text which makes it take much longer than it should  I do prefer the whitelist approach and wish I had used it in my original answer  Anyhow  by specifying the input part of the selector  plus the cache of the form element  this should make it the best performing answer here  This answer might still have some flaws if people s default for select elements is not an option that has a blank value  but it is certainly as generic as it is going to get and this would need to be handled on a case-by-case basis

I m using Paolo Bergantino solution which is great but with few tweaks    Specifically to work with the form name instead an id   For example   function jqResetForm form          input   form name   form          not   button   submit   reset   hidden       val         removeAttr  checked       removeAttr  selected        Now when I want to use it a could do   lt span class  button  onclick  jqResetForm  formName    gt Reset lt  span gt    As you see  this work with any form  and because I m using a css style to create the button the page will not refresh when clicked  Once again thanks Paolo for your input  The only problem is if I have defaults values in the form

basically none of the provided solutions makes me happy   as pointed out by a few people they empty the form instead of resetting it    however  there are a few javascript properties that help out     defaultValue for text fields defaultChecked for checkboxes and radio buttons defaultSelected for select options   these store the value that a field had when the page was loaded    writing a jQuery plugin is now trivial    for the impatient    here s a demo http   jsfiddle net kritzikratzi N8fEF 1    plugin-code   function             fn resetValue   function               return this each function                 var  this     this                var node   this nodeName toLowerCase                 var type    this attr   type                   if  node     input   amp  amp    type     text     type     password                       this value   this defaultValue                             else if  node     input   amp  amp    type     radio     type     checkbox                       this checked   this defaultChecked                             else if  node     input   amp  amp    type     button     type     submit     type  reset                           we really don t care                            else if  node     select                     this selectedIndex    this find   option    filter  function                        return this defaultSelected    true                       index                              else if  node     textarea                     this value   this defaultValue                                not good    unknown element  guess around             else if  this hasOwnProperty   defaultValue                       this value   this defaultValue                             else                     panic  must be some html5 crazyness                                     jQuery     usage     reset a bunch of fields      input1   input2   select1    resetValue         reset a group of radio buttons     input name myRadioGroup     resetValue         reset all fields in a certain container      someContainer  input    resetValue         reset all fields      input    resetValue         note that resetting all fields is better with the javascript-builtin command        myForm    get 0  reset       some notes       i have not looked into the new html5 form elements  some might need special treatment but the same idea should work   elements need to be referenced directly  i e       container    resetValue   won t work  always use      container  input    instead   as mentioned above  here is a demo  http   jsfiddle net kritzikratzi N8fEF 1
