jQuery AJAX submit form

Question

I have a form with name orderproductForm and an undefined number of inputs   I want to do some kind of jQuery get or ajax or anything like that that would call a page through Ajax  and send along all the inputs of the form orderproductForm   I suppose one way would be to do something like  jQuery get  myurl              action   document orderproductForm action value             cartproductid   document orderproductForm cartproductid value             productid   document orderproductForm productid value                   However I do not know exactly all the form inputs  Is there a feature  function or something that would just send ALL the form inputs

jQuery AJAX submit form  is nothing but submit a form using form ID when you click on a button  Please follow steps   Step 1 - Form tag must have an ID field   lt form method  post  class  form-horizontal  action  test user add  id  submitForm  gt         lt  form gt    Button which you are going to click   lt button gt Save lt  button gt    Step 2 - submit event is in jQuery which helps to submit a form  in below code we are preparing JSON request from HTML element name       submitForm   submit function e        e preventDefault        var frm       submitForm        var data             each this  function i  v           var input     v           data input attr  name      input val            delete data  undefined                  ajax           contentType  application json  charset utf-8           type frm attr  method            url frm attr  action            dataType  json           data JSON stringify data           success function data                alert data message                           for live demo click on below link  How to submit a Form using jQuery AJAX

I know this is a jQuery related question  but now days with JS ES6 things are much easier  Since there is no pure javascript answer  I thought I could add a simple pure javascript solution to this  which in my opinion is much cleaner  by using the fetch   API  This a modern way to implements network requests  In your case  since you already have a form element we can simply use it to build our request   const form   document forms  orderproductForm    const formInputs   form getElementsByTagName  input     let formData   new FormData     for  let input of formInputs        formData append input name  input value       fetch form action                method  form method          body  formData             then response   gt  response json         then data   gt  console log data        catch error   gt  console log error message        finally      gt  console log  Done

You can also use FormData  But not available in IE    var formData   new FormData document getElementsByName  yourForm   0      yourForm  form selector           ajax       type   POST       url   yourURL     where you wanna post     data  formData      processData  false      contentType  false      error  function jqXHR  textStatus  errorMessage            console log errorMessage      Optional            success  function data   console log data          This is how you use FormData

There are a few things you need to bear in mind   1  There are several ways to submit a form   using the submit button by pressing enter by triggering a submit event in JavaScript possibly more depending on the device or future device     We should therefore bind to the form submit event  not the button click event  This will ensure our code works on all devices and assistive technologies now and in the future   2  Hijax  The user may not have JavaScript enabled  A hijax pattern is good here  where we gently take control of the form using JavaScript  but leave it submittable if JavaScript fails   We should pull the URL and method from the form  so if the HTML changes  we don t need to update the JavaScript   3  Unobtrusive JavaScript  Using event preventDefault   instead of return false is good practice as it allows the event to bubble up  This lets other scripts tie into the event  for example analytics scripts which may be monitoring user interactions   Speed  We should ideally use an external script  rather than inserting our script inline  We can link to this in the head section of the page using a script tag  or link to it at the bottom of the page for speed  The script should quietly enhance the user experience  not get in the way   Code  Assuming you agree with all the above  and you want to catch the submit event  and handle it via AJAX  a hijax pattern   you could do something like this     function          form my form   submit function event        event preventDefault       Prevent the form from submitting via the browser     var form     this         ajax         type  form attr  method          url  form attr  action          data  form serialize          done function data             Optionally alert the user of success here           fail function data             Optionally alert the user of an error here                        You can manually trigger a form submission whenever you like via JavaScript using something like     function          form my form   trigger  submit          Edit   I recently had to do this and ended up writing a plugin     function          fn autosubmit   function         this submit function event          event preventDefault          var form     this           ajax           type  form attr  method            url  form attr  action            data  form serialize            done function data               Optionally alert the user of success here             fail function data               Optionally alert the user of an error here                          return this         jQuery    Add a data-autosubmit attribute to your form tag and you can then do this   HTML   lt form action   blah  method  post  data-autosubmit gt     lt  -- Form goes here -- gt   lt  form gt    JS    function          form data-autosubmit    autosubmit

I really liked this answer by superluminary and especially the way he wrapped is solution in a jQuery plugin  So thanks to superluminary for a very useful answer  In my case  though  I wanted a plugin that would allow me to define the success and error event handlers by means of options when the plugin is initialized   So here is what I came up with     function defaults     undefined        var getSubmitHandler   function onsubmit  success  error            return function event                if  typeof onsubmit      function                     onsubmit call this  event                             var form     this                 ajax                   type  form attr  method                    url  form attr  action                    data  form serialize                  done function                     if  typeof success      function                         success apply this  arguments                                    fail function                     if  typeof error      function                         error apply this  arguments                                                 event preventDefault                            fn extend              Usage             jQuery selector  ajaxForm                                            onsubmit function                                               success function                                                error  function                                                        ajaxForm   function options                options     extend     defaults  options               return   this  each function                       this  submit getSubmitHandler options  onsubmit    options  success    options  error                                               jQuery     This plugin allows me to very easily  ajaxify  html forms on the page and provide onsubmit  success and error event handlers for implementing feedback to the user of the status of the form submit  This allowed the plugin to be used as follows       form   ajaxForm         onsubmit  function event                 User submitted the form                success  function data  textStatus  jqXHR                 The form was successfully submitted                error  function jqXHR  textStatus  errorThrown                 The submit action failed                Note that the success and error event handlers receive the same arguments that you would receive from the corresponding events of the jQuery  ajax method

There s also the submit event  which can be triggered like this     form id   submit    You d use this method if the form is well represented in HTML already  You d just read in the page  populate the form inputs with stuff  then call  submit    It ll use the method and action defined in the form s declaration  so you don t need to copy it into your javascript   examples
