Question

我有代码：

win = desktop.createWindow({
    id: 'admin-win',
    title: 'Add administration users',
    width: 740,
    height: 480,
    iconCls: 'icon-grid',
    animCollapse: false,
    constrainHeader: true,
    xtype: 'form',
    bodyPadding: 15,
    url: 'save-form.php',
    items: [{
        xtype: 'textfield',
        fieldLabel: 'Field',
        name: 'theField'
    }],

    buttons: [{
        text: 'Submit',
        handler: function () {
            var form = this.up('form').getForm();
            if (form.isValid()) {
                form.submit({
                    success: function (form, action) {
                        Ext.Msg.alert('Success', action.result.message);
                    },
                    failure: function (form, action) {
                        Ext.Msg.alert('Failed', action.result ? action.result.message : 'No response');
                    }
                });
            }
        }
    }]
});

按钮不起作用。它会产生错误 - this.up（'form'）未定义。如何在这样的代码中调用getForm（）？

更新：谢谢你真的快速回复！我根据需要修改了代码，就是这样，它适用于桌面示例：

win = desktop.createWindow({
    id: 'admin-win',
    title: 'Add administration users',
    width: 740,
    iconCls: 'icon-grid',
    animCollapse: false,
    constrainHeader: true,
    items: [{
        xtype: 'form',
        bodyPadding: 15,
        url: 'save-form.php',
        items: [{
            xtype: 'textfield',
            fieldLabel: 'Field',
            name: 'theField'
        }],

        buttons: [{
            text: 'Submit',
            handler: function () {
                var form = this.up('form').getForm();
                if (form.isValid()) {
                    this.up().up().submit({
                        success: function (form, action) {
                            Ext.Msg.alert('Success', action.result.message);
                        },
                        failure: function (form, action) {
                            Ext.Msg.alert('Failed', action.result ? action.result.message : 'No response');
                        }
                    });
                }
            }
        }]
    }]
});

正如我已经说过的，您的代码似乎有问题。您正在将Ext.form.Panel选项传递给Ext.window.Window（我假设这是因为您正在调用的方法的名称）。我正在为你写一个带窗口的例子。片刻。

准备就绪。看看：

Ext.create('Ext.window.Window', {
    title: 'This is a Window with a Form',
    height: 200,
    width: 400,
    layout: 'fit',
    items: [{  // the form is an item of the window
        id: 'admin-win',
        title: 'Add administration users',
        width: 740,
        height: 480,
        iconCls: 'icon-grid',
        animCollapse: false,
        constrainHeader: true,
        xtype: 'form',
        bodyPadding: 15,
        url: 'save-form.php',
        items: [{
            xtype: 'textfield',
            fieldLabel: 'Field',
            name: 'theField',
            allowBlank: false
        }],
        buttons: [{
            text: 'Submit',
            handler: function() {
                var form = this.up('form').getForm();
                if (form.isValid()) {
                    form.submit({
                        success: function(form, action) {
                           Ext.Msg.alert('Success', action.result.message);
                        },
                        failure: function(form, action) {
                            Ext.Msg.alert('Failed', action.result ? action.result.message : 'No response');
                        }
                    });
                } else {
                    Ext.Msg.alert( "Error!", "Your form is invalid!" );
                }
            }
        }]
    }]
}).show();
