how to get GET and POST variables with JQuery?

I have the following HTML:

<form action='.' method='post'>{% csrf_token %}
    <div class="parameters">
        Show
            <select name="earnings_filter">
                <option value="all">Total earnings</option>
                <option value="hd">HD earnings</option>
                <option value="sd">SD earnings</option>
            </select>
        <input type="submit" name="submit" class="submit float-right" value="submit" id="submit_financials"/>
    </div>
</form>

I need to do an ajax call with this, which I’m triggering on:

$("#submit_financials").live('click', function(){
    ...
});

Is there a way to get the variables that are submitted in POST, for example which option was selected (and there are about 10 other variables I need to get). Or do I need to use the jQuery selectors to get the value of each?

Answer 1

$("#submit_financials").live('click', function(){
    $.ajax({
      url: '', // script url to send
      method: 'POST', // method of sending
      data: $('form').has(this).serialize(),  // .serialize() make query string with form inputs name and value
      dataType:'json',  // expected data format returned from server, you may have something else
      success: function(response) {
          // response contains data returned from server
      }
    });
});

It would be better replace live() with .on() if you’re using jQuery > 1.7 and it’d be better if possible. So you can write it

$("#container").on('click', '#submit_financials', function(){
    $.ajax({
      url: '', // script url to send
      method: 'POST', // method of sending
      data: $('form').has(this).serialize(),  // .serialize() make query string with form inputs name and value
      dataType:'json',  // expected data format returned from server, you may have something else
      success: function(response) {
          // response contains data returned from server
      }
    });
});

Here #container point to holder of #submit_financials that belong to DOM at page load.
