8 May 20234 minutes to read

You can customize the dialog appearance by providing dialog template as string or HTML element to the content property. In the following sample, dialog is customized as error window appearance.

ej.base.enableRipple(true);

var dlgObj = new ej.popups.Dialog({
    header: 'File and Folder Rename',
    content: document.getElementById("dlgContent"),
    showCloseIcon: true,
    visible: false,
    buttons: [{
        buttonModel: { isPrimary: true, content: 'close' }, click:  function() { this.hide() }
    }],
    target: document.querySelector('body'),
    width: '400px',
    animationSettings: { effect: 'Zoom' },
    beforeOpen: onBeforeopen
});
dlgObj.appendTo('#dialog');

var button = new ej.buttons.Button({});
button.appendTo('#dialogButton');

document.getElementById('openBtn').onclick = function () {
    dlgObj.show();
};

function onBeforeopen() {
    document.getElementById('dlgContent').style.visibility = 'visible';
}
