How to implement a periodical save of a form in the background? Same kinda thing that gmail does.

setInterval(function(){
  var form = $('#my-form-id');
  var method = form.attr('method').toLowerCase();      // "get" or "post"
  var action = form.attr('action');                    // url to submit to
  $[method](action, form.serialize(), function(data){
    // Do something with the server response data      
    // Or at least let the user know it saved
  });
},10000);                                              // do it every 10 seconds

If you don't want to use the method of the form, but always want to use 'post', then use:

$.post(action, form.serialize(), ... );

And, if you want to supply your own action for the autosave that is different from the action for the actual save:

$.post("/autosave/comments", form.serialize(), ... );

You would need a timed loop on the client side that would save the form every x seconds/minutes. A crude way of doing this would be to have a setTimeout javascript function that collects the form's field values and updates the model via an update (PUT in Rails' case) AJAX request.

Example

Here's a crude way of doing it (i.e. there might be a better way):

// repeat every 10 seconds
var repeatTime = 10 * 1000; 

function updateModel(){
    // get field values (using jQuery, etc.)
    // make ajax request using these field values 
    //(make sure put parameters match model attribute names)
    console.log('updated');
    setTimeout(updateModel, repeatTime); // start call over again
}

setTimeout(updateModel, repeatTime);

I included the console.log so that you can test this out in Firebug right now and see that the updateModel executes every 10 seconds. I would recommend using jQuery to generate the PUT AJAX requests.

Comments
  • @flOOr Yes periodical ajax requests.
  • @flOOr Can you provide any example ?
  • On SO people like when you write some code that doesn't work and then everybody start to fix it :) Also it isn't about Ruby or Ruby on Rails
  • @krunal - I updated my answer with an example. Did that work for you?
  • -@Phrogz, can you explain in your 1st code block where form validation would go?
  • @timpeterson 3.5 years too late a response, but: I assume you are talking about client-side validation, and you don't want to submit the form if it's invalid? If so, then it's just code, right? if (formIsValid(form)) $[method](...);
  • Can you provide any example ?
  • Why not use setInterval() instead of setTimeout()?
