Contain form within a bootstrap popover?

<div class="container">
    <div class="row" style="padding-top: 240px;">
        <a href="#" class="btn btn-large btn-primary" rel="popover"
            data-content="<form><input type="text"/></form>"
            data-placement="top" data-original-title="Fill in form">Open form</a>
    </div>
</div>

JSfiddle

I'm guessing that I would store the form contents within a javascript function...

How do I contain a form within a bootstrap popover?

I would put my form into the markup and not into some data tag. This is how it could work:

JS Code:

$('#popover').popover({ 
    html : true,
    title: function() {
      return $("#popover-head").html();
    },
    content: function() {
      return $("#popover-content").html();
    }
});

HTML Markup:

<a href="#" id="popover">the popover link</a>
<div id="popover-head" class="hide">
  some title
</div>
<div id="popover-content" class="hide">
  <!-- MyForm -->
</div>

Demo

Alternative Approaches:

X-Editable

You might want to take a look at X-Editable. A library that allows you to create editable elements on your page based on popovers.

Webcomponents

Mike Costello has released Bootstrap Web Components. This nifty library has a Popovers Component that lets you embed the form as markup:

<button id="popover-target" data-original-title="MyTitle" title="">Popover</button>

<bs-popover title="Popover with Title" for="popover-target">
  <!-- MyForm -->
</bs-popover>

Demo

Either replace double quotes around type="text" within single quotes, Like:

"<form><input type='text'/></form>"

OR

Replace Double quotes wrapping data-content with single quote, Like:

data-content='<form><input type="text"/></form>'

<a data-title="A Title" data-placement="top" data-html="true" data-content="<form><input type='text'/></form>" data-trigger="hover" rel="popover" class="btn btn-primary" id="test">Top popover</a>

> just state data-html="true"

like this Working demo http://jsfiddle.net/7e2XU/21/show/#

• Update: http://jsfiddle.net/kz5kjmbt/

You can load the form from a hidden div element with the Bootstrap-provided hidden class.

<button class="btn btn-default" id="form-popover">Form popover</button>

<div class="hidden">
  <form id="form">
    <input type="text" class="form-control" />
  </form>
</div>

JavaScript:

$('#form-popover').popover({
    content: $('#form').parent().html(),
    html: true,
});

A complete solution for anyone that might need it, I've used this with good results so far

JS:

$(".btn-popover-container").each(function() {
	var btn = $(this).children(".popover-btn");
	var titleContainer = $(this).children(".btn-popover-title");
	var contentContainer = $(this).children(".btn-popover-content");

	var title = $(titleContainer).html();
	var content = $(contentContainer).html();

	$(btn).popover({
		html: true,
		title: title,
		content: content,
		placement: 'right'
	});
});

HTML:

<div class="btn-popover-container">
	<button type="button" class="btn btn-link popover-btn">Button Name</button>
	<div class="btn-popover-title">
		Popover Title
	</div>
	<div class="btn-popover-content">
		<form>
          Or Other content..
		</form>
	</div>
</div>

CSS:

.btn-popover-container {
    display: inline-block;
}


.btn-popover-container .btn-popover-title, .btn-popover-container .btn-popover-content {
    display: none;
}

I work in WordPress a lot so use PHP.

My method is to contain my HTML in a PHP Variable, and then echo the variable in data-content.

$my-data-content = '<form><input type="text"/></form>';

along with

data-content='<?php echo $my-data-content; ?>'
