form submitting html content with jQuery

<form id="form1">
<ul>
<li>Content</li>
<li>Content</li>
<li>Content</li>
</ul>
<input type="submit" value="Submit" />
</form>

I want to send the content in the ul tag when clicking the submit button.

the submitted data should be

<li>Content</li>
<li>Content</li>
<li>Content</li>

How would I write this in jquery and with proper char. escaping for the <>'s

Disclaimer: This is an alternative to my other AJAX based answer.

You can do this by setting the value of a hidden field with javascript. Also, your form needs an "action" attribute - it has to be submitted to somewhere.

<!-- HTML -->
<form action="/my_script.php" id="my_id">
  <ul>
    Stuff...
  </ul>
  <input type="hidden" name="html />
</form>

The script:

$("#my_id").submit(function () {
  var html = $(this).find("ul").html();
  $(this).find("input[name=html]").val(escape(html));
  // don't return false, we want the submit event to go through
});

The form will submit, and the hidden field will have the escaped HTML from the <ul></ul> tag as value.

To hook the submit, do this:

$("#form1").submit(function () {
  // do stuff
  return false;
});

Replace the // do stuff part with one of the following:

$.ajax({
  url: "...",
  type: "POST",
  data: $("#form1 ul").html()
});

If you want to escape it, I'd do it on the server side. You can also do this, to perform a client side escape:

$.ajax({
  url: "...",
  type: "POST",
  data: escape($("#form1 ul").html())
});

I think the most elegant solution would be to send it as JSON to the server.

$.ajax({
  url: "...",
  dataType: "json",
  // the value of `type` is irrelevant here
  data: {html: $("#form1 ul").html(), moreMetadDtaIfYouWant: 5}
});

But that's your call ;)

Well I think you're going to have to submit your values inside some form field so you're going to first have to create a input of some type, probably hidden if I had to venture a guess, with in your form.

<input id="your_id" type="hidden" />

Then using jquery you could do this in the onSubmit of the form...

$("#form1").submit(function(){
  $("#your_id").val($("#form1 ul").html());
}

I'm not sure if the form will automatically escape the html you're submitting or not though.
