        1.2  实现代码

            //标签页

                    });
            });

        代码说明:

          a).  这里封装了树形控件的创建和节点添加

      二、其他控件

        8.2.aspx

        2.1  先来张大合照

         

        2.2  实现代码

          2.2.1  下拉框、菜单[CycleButton、SplitButton]

                var btn = new Ext.CycleButton({
                    showText: 
    true,
                    prependText: 
    'View as ',
                    items: [{
                        text:
    'text only',
                        iconCls:
    'view-text',
                        checked:
    true
                    },{
                        text:
    'HTML',
                        iconCls:
    'view-html'
                    }],
                    changeHandler:
    function(btn, item){
                        Ext.Msg.alert(
    'Change View', item.text);
                    }
                });
                
                
    //二级菜单
                var sb = new Ext.SplitButton({
                       text: 
    '二级菜单',
                       menu: 
    new Ext.menu.Menu({
                        items: [{
                            text: 
    'Item 1',
                            menu:
    new Ext.menu.Menu({
                                items: [
                                    {text: 
    'Item 3'},
                                    {text: 
    'Item 4'}
                                ]
                               })
                        }]
                       })
                });

          2.2.2  调色板[ColorPalette]

                //调色板
                var cp = new Ext.ColorPalette({
                    value:
    '993300',       //默认值
                    listeners: {
                        
    'select':function(palette, selColor){
                            Ext.Msg.alert(
    '颜色', selColor);
                        }
                    }
                });  

          2.2.3  滑动条[Slider]

                //滑动条
               var slider = new Ext.Slider({
                     
    200,
                    value: 
    50,
                    increment: 
    10,
                    minValue: 
    0,
                    maxValue: 
    100
                });

           2.2.4  日历[DatePicker]

      写完这篇关于关于Ext控件基本上就告一段落了,随着版本的更新会慢慢的不断新增更多的控件,如果再在项目中使用Ext的话,再考虑写续了 :)
