DevExtreme jQuery - Show and Hide the Popup

API

NOTE
In this article, the Button widget is used to demonstrate how to show and hide the Popup. This choice is made for purely demonstrational purposes, and you can do the same operations using another widget following the same guidelines.

To show or hide the Popup programmatically, call the show() or hide() method. The same thing can be done using the toggle(showing) method. Pass true or false to this method to show or hide the Popup, respectively.

jQuery
JavaScript
$(function() {
    $("#popupContainer").dxPopup({
        title: "Popup Title",
        contentTemplate: function () {
            return $("<p />").text("Popup content");
        }
    });
    $("#showButton").dxButton({
        text: "Show the Popup", 
        onClick: function () {
            $("#popupContainer").dxPopup("show");
            // === or ===
            $("#popupContainer").dxPopup("toggle", true);
        } 
    });
    $("#hideButton").dxButton({
        text: "Hide the Popup", 
        onClick: function () {
            $("#popupContainer").dxPopup("hide");
            // === or ===
            $("#popupContainer").dxPopup("toggle", false);
        } 
    });
});

    function showButton_click() {
        $("#popup").dxPopup("show");
        // === or ===
        $("#popup").dxPopup("toggle", true);
    }
    function hideButton_click() {
        $("#popup").dxPopup("hide");
        // === or ===
        $("#popup").dxPopup("toggle", false);
    }
</script>

With Angular, AngularJS or Knockout, use a different technique. Bind the visible property of the Popup widget to a component property (in Angular), a scope property (in AngularJS), or an observable variable (in Knockout). After that, change them, and the Popup will appear or disappear.

Angular
HTML
TypeScript
<dx-popup
    title="Popup Title"
    [(visible)]="isPopupVisible">
    <div *dxTemplate="let data of 'content'">
        <p>Popup content</p>
    </div>
</dx-popup>
<dx-button
    text="Show the Popup"
    (onClick)="isPopupVisible = true">
</dx-button>
<dx-button
    text="Hide the Popup"
    (onClick)="isPopupVisible = false">
</dx-button>
import { DxPopupModule } from "devextreme-angular";
// ...
export class AppComponent {
    isPopupVisible: boolean = false;
}
@NgModule({
    imports: [
        // ...
        DxPopupModule
    ],
    // ...
})
AngularJS
HTML
JavaScript
<div ng-controller="DemoController">
    <div dx-popup="{
        title: 'Popup Title',
        bindingOptions: {
            visible: 'isPopupVisible'
        }
    }">
        <p>Popup Content</p>
    </div>
    <div dx-button="{
        text: 'Show the Popup',
        onClick: showPopup
    }"></div>
    <div dx-button="{
        text: 'Hide the Popup',
        onClick: hidePopup
    }"></div>
</div>
angular.module('DemoApp', ['dx'])
    .controller('DemoController', function DemoController($scope) {
        $scope.isPopupVisible = false;
        $scope.showPopup = function () {
            $scope.isPopupVisible = true;
        };
        $scope.hidePopup = function () {
            $scope.isPopupVisible = false;
        };
    });
Knockout
HTML
JavaScript
<div data-bind="dxPopup: {
    title: 'Popup Title',
    visible: isPopupVisible
}">
    <p>Popup Content</p>
</div>
<div data-bind="dxButton: {
    text: 'Show the Popup',
    onClick: function (e) {
        e.model.isPopupVisible(true);
    }
}"></div>
<div data-bind="dxButton: {
    text: 'Hide the Popup',
    onClick: function (e) {
        e.model.isPopupVisible(false);
    }
}"></div>
var viewModel = {
    isPopupVisible: ko.observable(false)
};

ko.applyBindings(viewModel);

User Interaction

The Popup can also be hidden when a user clicks outside it. To control this behavior of the Popup, use the closeOnOutsideClick option.

jQuery
JavaScript
$(function() {
    $("#popupContainer").dxPopup({
        title: "Popup Title",
        visible: true,
        closeOnOutsideClick: true
    });
});
Angular
HTML
TypeScript
<dx-popup
    title="Popup Title"
    [(visible)]="isPopupVisible"
    [closeOnOutsideClick]="true">
</dx-popup>
import { DxPopupModule } from "devextreme-angular";
// ...
export class AppComponent {
    isPopupVisible: boolean = true;
}
@NgModule({
    imports: [
        // ...
        DxPopupModule
    ],
    // ...
})

Events

To execute certain commands before or after the Popup was shown/hidden, handle the showing, shown, hiding or hidden event. If the event handling function is not going to be changed during the lifetime of the widget, assign it to the corresponding onEventName option when you configure the widget.

jQuery
JavaScript
$(function () {
    $("#popupContainer").dxPopup({
        // ...
        onShowing: function (e) {
            // Handler of the "showing" event
        },
        onShown: function (e) {
            // Handler of the "shown" event
        },
        onHiding: function (e) {
            // Handler of the "hiding" event
        },
        onHidden: function (e) {
            // Handler of the "hidden" event
        }
    });
});
Angular
HTML
TypeScript
<dx-popup ...
    (onShowing)="popup_showing($event)"
    (onShown)="popup_shown($event)"
    (onHiding)="popup_hiding($event)"
    (onHidden)="popup_hidden($event)">
</dx-popup>
import { DxPopupModule } from "devextreme-angular";
// ...
export class AppComponent {
    popup_showing (e) {
        // Handler of the "showing" event
    }
    popup_shown (e) {
        // Handler of the "shown" event
    }
    popup_hiding (e) {
        // Handler of the "hiding" event
    }
    popup_hidden (e) {
        // Handler of the "hidden" event
    }
}
@NgModule({
    imports: [
        // ...
        DxPopupModule
    ],
    // ...
})

If you are going to change event handlers at runtime, or if you need to attach several handlers to a single event, subscribe to the events using the on(eventName, eventHandler) method. This approach is more typical of jQuery.

JavaScript
var hiddenEventHandler1 = function (e) {
    // First handler of the "hidden" event
};

var hiddenEventHandler2 = function (e) {
    // Second handler of the "hidden" event
};

$("#popupContainer").dxPopup("instance")
    .on("hidden", hiddenEventHandler1)
    .on("hidden", hiddenEventHandler2);
