Use it to submit your form using jquery. Here is the link http://api.jquery.com/submit/

<form id="form" method="post" action="#">
    <input type="text" id="input">
    <input type="button" id="button" value="Submit">
</form>

<script type="text/javascript">
$(document).ready(function () {
    $( "#button" ).click(function() {
        $( "#form" ).submit();
    });
});
</script>

I have also used the following to submit a form (without actually submitting it) via Ajax:

  jQuery.get("process_form.php"+$("#form_id").serialize(), {}, 
    function() {
      alert("Okay!"); 
    });

when you have an existing form, that should now work with jquery - ajax/post now you could:

• hang onto the submit - event of your form
• prevent default functionality of submit

• do your own stuff

  $(function() {
      //hang on event of form with id=myform
      $("#myform").submit(function(e) {
  
          //prevent Default functionality
          e.preventDefault();
  
          //get the action-url of the form
          var actionurl = e.currentTarget.action;
  
          //do your own request an handle the results
          $.ajax({
                  url: actionurl,
                  type: 'post',
                  dataType: 'application/json',
                  data: $("#myform").serialize(),
                  success: function(data) {
                      ... do something with the data...
                  }
          });
  
      });
  
  });
  

Please note that, in order for the serialize() function to work in the example above, all form elements need to have their name attribute defined.

Example of the form:

<form id="myform" method="post" action="http://example.com/do_recieve_request">

<input type="text" size="20" value="default value" name="my_input_field">
..
.
</form>

@PtF - the data is submitted using POST in this sample, so this means you can access your data via

 $_POST['dataproperty1'] 

, where dataproperty1 is a "variable-name" in your json.

here sample syntax if you use CodeIgniter:

 $pdata = $this->input->post();
 $prop1 = $pdata['prop1'];
 $prop1 = $pdata['prop2'];

It depends on whether you are submitting the form normally or via an AJAX call. You can find lots of information at jquery.com, including documentation with examples. For submitting a form normally, check out the submit() method to at that site. For AJAX, there are many different possibilities, though you probably want to use either the ajax() or post() methods. Note that post() is really just a convenient way to call the ajax() method with a simplified, and limited, interface.

A critical resource, one I use every day, that you should bookmark is How jQuery Works. It has tutorials on using jQuery and the left-hand navigation gives access to all of the documentation.

Examples:

Normal

$('form#myForm').submit();

AJAX

$('input#submitButton').click( function() {
    $.post( 'some-url', $('form#myForm').serialize(), function(data) {
         // ... do something with response from server
       },
       'json' // I expect a JSON response
    );
});

$('input#submitButton').click( function() {
    $.ajax({
        url: 'some-url',
        type: 'post',
        dataType: 'json',
        data: $('form#myForm').serialize(),
        success: function(data) {
                   // ... do something with the data...
                 }
    });
});

Note that the ajax() and post() methods above are equivalent. There are additional parameters you can add to the ajax() request to handle errors, etc.

You can also use the jquery form plugin to submit using ajax aswell:

Note that in Internet Explorer there are issues with dynamically created forms. A form created like this will not submit in IE (9):

var form = $('<form method="post" action="/test/Delete/">' +
             '<input type="hidden" name="id" value="' + myid + '"></form>');
$(form).submit();

To get it working in IE create the form element and attach it before submitting like so:

var form = document.createElement("form");
$(form).attr("action", "/test/Delete")
       .attr("method", "post");
$(form).html('<input type="hidden" name="id" value="' + myid + '" />');
document.body.appendChild(form);
$(form).submit();
document.body.removeChild(form);

Creating the form like in example 1 and then attaching it will not work - in IE9 it throws a JScript error DOM Exception: HIERARCHY_REQUEST_ERR (3)
