jquery-ui - jQuery UI 焦点问题

Question

我有问题

unable to get property'_focusTabbable'of undefined or null reference

我正在使用 Jquery-ui-1.10.2.custom.js

在这里我遇到了问题

if ( !$.ui.dialog.overlayInstances ) {
    // Prevent use of anchors and inputs.
    // We use a delay in case the overlay is created from an
    // event that we're going to be cancelling. (#2804)
    this._delay(function() {
        // Handle .dialog().dialog("close") (#4065)
        if ( $.ui.dialog.overlayInstances ) {
            this.document.bind( "focusin.dialog", function( event ) {
                if ( !that._allowInteraction( event ) ) {
                    event.preventDefault();
                    **$(".ui-dialog:visible:last .ui-dialog-content")
                        .data( widgetFullName )._focusTabbable();**
                }
            });
        }
    });
}

当您打开一个对话框，然后在此对话框的操作按钮中调用打开第二个对话框的方法时，就会出现此错误。当您尝试关闭第二个对话框时，会出现该错误。

为防止发生这种情况，请立即关闭第一个对话框，然后调用第二个对话框。

$('#dialog1').dialog({

    buttons: {
        'No': function () {
            $(this).dialog('close')
        },

        'Yes': function () {

            // This works
            $(this).dialog('close');

            // Open second dialog
            OpenSecondDialog()

            // This doesn't work.  A bug will arise when attempting to close the second dialog
            $(this).dialog('close');

        }
    }
});
