qtip2/src/core/focus.js

Introducing... qTip2. The second generation of the advanced qTip plugin for the ever popular jQuery framework.

PROTOTYPE.focus = function(event) {
	if(!this.rendered || this.destroyed) { return this; }

	var qtips = $(SELECTOR),
		tooltip = this.tooltip,
		curIndex = parseInt(tooltip[0].style.zIndex, 10),
		newIndex = QTIP.zindex + qtips.length;

	// Only update the z-index if it has changed and tooltip is not already focused
	if(!tooltip.hasClass(CLASS_FOCUS)) {
		// tooltipfocus event
		if(this._trigger('focus', [newIndex], event)) {
			// Only update z-index's if they've changed
			if(curIndex !== newIndex) {
				// Reduce our z-index's and keep them properly ordered
				qtips.each(function() {
					if(this.style.zIndex > curIndex) {
						this.style.zIndex = this.style.zIndex - 1;
					}
				});

				// Fire blur event for focused tooltip
				qtips.filter('.' + CLASS_FOCUS).qtip('blur', event);
			}

			// Set the new z-index
			tooltip.addClass(CLASS_FOCUS)[0].style.zIndex = newIndex;
		}
	}

	return this;
};

PROTOTYPE.blur = function(event) {
	if(!this.rendered || this.destroyed) { return this; }

	// Set focused status to FALSE
	this.tooltip.removeClass(CLASS_FOCUS);

	// tooltipblur event
	this._trigger('blur', [ this.tooltip.css('zIndex') ], event);

	return this;
};
