Backbone implementation of the Twitter Bootstrap Popover view

PopoverView.js

(function () {

  App.Views.PopoverView = Backbone.View.extend({

		initialize: function (options) {
			_.bindAll(this, "render", "setContent", "show", "hide", "toggle", "destroy", "remove");

			this.offsetTop = 30;
			this.offsetLeft = 0;

			if (options && options.header) {
				this.Header = options.header;
			}

			if (options && options.content) {
				this.Content = options.content;
			}

			if (options && options.placement) {
				this.Placement = options.placement;
			}

			if (options && options.trigger) {
				this.Trigger = options.trigger;
			}

			if (options && options.delay) {
				this.Delay = options.delay;
			}

			if (options && options.offsetTop && $.isNumeric(options.offsetTop)) {
				this.offsetTop += options.offsetTop;
			}

			if (options && options.offsetLeft && $.isNumeric(options.offsetLeft)) {
				this.offsetLeft += options.offsetLeft;
			}
		},

		render: function (show) {
			var that = this;

			this.popoverElement = $("<div />").addClass("popover-dummy").css("position", "absolute").appendTo($(document.body));

			this.popover = this.popoverElement.popover({
				title: this.Header,
				content: this.Content || "",
				placement: this.Placement || "left",
				trigger: this.Trigger || "click",
				delay: this.Delay || 0
			}).data("popover");

			if (show === true) {
				this.show();
			}

			return this;
		},

		setContent: function (el) {
			this.$body.empty().append(el);
		},

		show: function () {
			var position = this.$el.offset(),
				height = this.$el.height();

			this.popoverElement.css("top", position.top + (height / 2));
			this.popoverElement.css("left", position.left + this.offsetLeft);

			this.popoverElement.popover("show");
			this.$body = this.popover.$tip.find(".popover-content");

			if (!this.Content) {
				this.setContent(new App.Views.WaitSpinnerView().render().$el);
			}

			if (this.popover.options.placement === "left" || this.popover.options.placement === "right") {
				this.popover.$tip.find(".arrow").css("top", this.offsetTop);
			}

			$("<button type=\"button\" class=\"close\" data-dismiss=\"modal\">×</button>")
				.appendTo(this.popover.$tip.find(".popover-title"))
				.one("click", this.remove);
		},

		hide: function () {
			this.popoverElement.popover("hide");
		},

		toggle: function () {
			this.popoverElement.popover("toggle");
		},

		destroy: function () {
			this.popoverElement.popover("destroy");
			this.popoverElement.remove();
			this.popoverElement = null;
		},

		remove: function () {
			this.destroy();
		}

	});

})();

I added html attribute to passthrough to bootstrap, my button is #button

this.popoverView = new App.Views.PopoverView({
          el: '#Button',
          content: InteriorView.render().el,
          html: true, /*XSS warning from bootstrap, avoid using this technique on user data*/
          placement: 'bottom'
        });

events: {
  "click #Button": "showPopover"
},
showPopover: function () {
  this.popoverView.render(true);
},

It rendered mostly like a normal popover, but hasn't centered perfectly for me yet. For me, it successfully skirts the problem of the Backbone events getting detached when bootstrap does a $.remove() on the content element for the first time.

Make sure to remove or redefine the Spinner.

Use .data("bs.popover") instead of .data("popover") in Bootstrap 3
