The Goal
- I am trying to use AJAX to post data (from a form on "Page A") to another page ("Page B")
- I want some content from "Page B" to be loaded into "Page A" within a specified div (#result).
What I've Tried
- I've created the relevant HTML and JS largely-based on the jQuery
.post()
documentation with some influence from jQuery AJAX submit form. - I've tinkered with alert() to see where the process is failing.
- I've created a jsFiddle at http://jsfiddle.net/jhfrench/QjaTq/ (the HTML and JavaScript that follow are the same)
The Symptoms
- Page A is submitting directly to Page B, as if the form were submitting normally and there were no jQuery to intercede.
Theories
- the
.submit()
method is not attaching - or it is attaching but the
preventDefault
directive within is not intercepting the traditional form submission
HTML
<form action="/echo/html/" id="form_edit_sensitivity" method="post" onsubmit="trimTextFields(this); return checkForm(this);" class="form-horizontal">
<div class="control-group">
<label for="p_sensitivity_type_id" class="control-label">Group</label>
<div class="controls">
<select name="p_sensitivity_type_id" size="1" title="Sensitivity Type" id="p_sensitivity_type_id">

</form>
<div id="result">We want to load the results within this div</div>
JavaScript
var trimTextFields = function () {
alert('trim fields');
},
checkForm = function (incoming_form) {
alert('custom validation');
};
/* attach a submit handler to the form */
$('#form_edit_sensitivity').submit(function (event) {
/* stop form from submitting normally */
event.preventDefault();
confirm('we got this far');
/* get some values from elements on the page: */
var $form = $(this),
data = $form.serialize(),
url = $form.attr('action');
/* Send the data using post */
var posting = $.post(url, data);
/* Put the results in a div */
posting.done(function (data) {
var content = $(data).find('#summary');
$('#result').empty().append(content);
});
});
To paraphrase the immortal words of the "Deranged Sorority Girl", I am about ready to C-Punt my computer over this one.
