ExtJs4常用配置方法备忘

viewport布局常用属性

 

            new Ext.Viewport({

                layout: "border",

                renderTo: Ext.getBody(),

                defaults: {

                    bodyStyle: "background-color: #FFFFFF;",

                    frame: true

                },

                //split为true，即可达到上下左右拉伸效果

                //layout:fit，填满布局

                //collapsible:true，north模块被收缩到最上面

                items: [{ region: "north", height: "60%", collapsible: true, split: true, layout: "fit", border: true, items: [ClassTreeGrid] },

                        { region: "center", autoScroll: true, split: true, border: true, layout: "fit", items: [RecGrid] }

                ]

            });

Ext.window.Window拉伸属性,以及textareafield，form的可拉伸属性

提醒：resizable: true, //是否可以拉伸，同时也适用于textareafield，form等

 var AddDialog = Ext.create("Ext.window.Window", {

                layout: "fit",

                iconCls: 'a_add',

                closeAction: 'hide',        //窗口关闭的方式：hide/close

                resizable: true,            //是否可以拉伸

                closable: true,            //是否可以关闭

                modal: true,                //是否为模态窗口

                items: AddForm,

                buttons: [{

                    text: '添加',

                    iconCls: 'a_add',

                    id: "btnAdd",

                    handler: Add

                },

                {

                    id: "btnCancel",

                    iconCls: 'a_cross',

                    text: '重置',

                    handler: function () {

                        AddForm.form.reset();

                    }

                }]

            });

为空默认值，验证配置，及验证方法，column布局

 var AddForm = Ext.create("Ext.form.Panel", {

                border: false,

                fieldDefaults: {

                    msgTarget: 'side',  //提示信息在右旁边显示图标

                    labelWidth: 70,

                    align: "right",

                    allowBlank: false //不与许为空

                },

                width: 380,

                defaults: {

                    padding: 10,

                },

                layout: 'column',

                items: [

                     {

                         xtype: "hidden",

                         name: 'quId',

                     },

                      {

                          xtype: "numberfield",

                          fieldLabel: '第几题',

                          name: 'sorts',

                          regex: /^\d+$/,  //正则验证

                          maxLength: 100,

                          columnWidth: 1,

                      },

                    {

                        xtype: "combo",

                        fieldLabel: '皮肤分类',

                        name: 'claId',

                        id: 'claId',

                        valueField: 'qcId',

                        displayField: 'claName',

                        columnWidth: 1,   //列布局站的比例，总共为1，多分为0.5+0.5 ....和为1 

                        allowBlank: false,

                        store: QuestionClassStore,

                        emptyText: "请选择皮肤分类", //为空输入框暗灰提示

                        blankText: "请选择皮肤分类111", //错误提示

                    },

                     {

                         xtype: "filefield",

                         fieldLabel: '上传图片',

                         buttonText: '  浏 览  ',

                         regex: /^.+\.((jpg)|(gif)|(gif)|(png)|(jpeg)|(bmp))$/, //正则验证

                         name: 'queImg',

                         allowBlank: true, //不允许为空

                         columnWidth: 1

                     },

                     {

                         xtype: "textareafield",

                         grow: true,

                         fieldLabel: '问题',

                         name: 'question',

                         columnWidth: 1

                     }



                ]

            });



            //添加问题

            function Add() {

                var form = AddForm.getForm();  //获取表单form

                if (form.isValid()) {   //验证表单

                    form.submit({

                        url: "/question/Add",

                        params: { json: Ext.JSON.encode(AddForm.form.getValues()) },

                        waitMsg: '正在上传请稍候...',

                        success: function (form, action) {

                            Ext.Msg.alert("提示", action.result.msg);

                            QuestionGridStore.load();

                        },



                    })

                }

            }

给img的路径src赋值

               itemclick: function () {

                        var rows = ShopPaperGrid.getView().getSelectionModel().getSelection();

                        if (typeof (rows[0]) != "undefined") {

                            Ext.getCmp("imgForm").getEl().dom.src = rows[0].data.imgPath;   //给src赋值

                        }

                        else {

                            Ext.getCmp("imgForm").getEl().dom.src = "/images/default.jpg";

                        }

                    }

ext.msg.confrim()

   Ext.Msg.confirm("提示", "确定删除", function (btn) {

                //btn=yes或者no

                if (btn == "yes") {

                    alert("删除成功");

                }

                else {

                    alert("取消啦删除");

                }

            });
