Attach JavaScript Popover to a Page Element

JavaScript Popover displays an arrow that points to a page element. To specify the element, set the target property to a CSS selector. In this demo, target elements are selected by id.

You can use the position property to position JavaScript Popover relative to the target element. If you do not specify this property, JavaScript Popover is displayed under the element.

Show and Hide JavaScript Popover

The showEvent and hideEvent properties allow you to show and hide JavaScript Popover in response to certain events. These properties can accept one or multiple names of DOM events or DevExtreme UI events separated by a space character.

You can also specify a delay before the events occur. Set the showEvent and hideEvent properties to an object with the name (one or multiple event names) and delay properties.

In this demo, the last JavaScript Popover appears when you click its target element because its showEvent property is set to the DevExtreme dxclick event. Other JavaScript Popover components appear and disappear on the mouseenter and mouseleave DOM events.

Specify Content

JavaScript Popover consists of content area and a title. You can specify static content in the HTML markup as shown in this demo. If JavaScript Popover should display dynamic content, use the contentTemplate property to specify a template. To display the title, enable the showTitle property and set the title property to the title text.

Animate JavaScript Popover

If you want to show and hide JavaScript Popover with animation effects, assign an object with the show and hide fields to the animation property. Each of these fields accepts an object that configures the animation type and other properties. In this demo, JavaScript Popover appears with a pop-up animation and fades away when it disappears.

Shade the Background

You can show JavaScript Popover with a shaded background. To do this, enable the shading property and specify a shadingColor.
