Ext 项目随笔

region:

This region's layout position (north, south, east, west or center). Read-only.

collapsible:true  收缩/展开

floatable:false  是否允许浮动

 删除window中的item,下标无效中

var items = win.items;
win.remove(items.last());

 选择行,getSelected()无效中

var selModel = grid.getSelectionModel();
if (selModel.hasSelection()) {
rs = selModel.getLastSelected();
Ext.Msg.alert("提示", rs.get('RoleID'));

获取表的store,使用store的ID无效

var store = Ext.getCmp('RoleAcc_operatePanel_Table').store;

 设置不允许为空的文本框

allowBlank:false,

多项不能为空

function setDiyTextField(){
    Ext.ComponentMgr.all.each(function(cmp){
        var Type=cmp.getXType();
        if(Type=='textfield'||Type=='fileuploadfield'||Type=='combo'||Type=='treecombo'||Type=='datefield'||Type=='numberfield'||Type=='textarea'||Type=='timefield'||Type=='trigger'){
               if(cmp.allowBlank==false){
                   cmp.cls="Diy-text";
                   cmp.blankText="该输入项不能为空！";
                         }
        }
    });
}

执行等待提示

Ext.MessageBox.show({
                               title:         '请稍等',
                               msg:         '正在提交数据...',
                               progressText: '',
                               width:        300,
                               progress:    true,
                               closable:    false,
                               animEl:         'loding'
                           });

Ext.MessageBox.hide();

 复选框自动赋值方法(一)

{
                                xtype: 'checkcolumn',
                                flex: 1,
                                text: '选中',
                                stopSelection: false,
                                renderer: function (val, m, rec) {
                                    var flag = rec.get('id').split('_');
                                    if (flag[1]=='true')
                                        return (new Ext.grid.column.CheckColumn).renderer(true);
                                    else {
                                        return (new Ext.grid.column.CheckColumn).renderer(false);
                                    }
                                }
                            }

复选框自动赋值方法(二)

后台的json:            
string str = "[{text:'总公司1',id:'123',check:false,children:[{text:'部门1',id:'234',leaf:true,check:true}]},{text:'总公司2',id:'258',leaf:true,check:false}]";
字符串中的check的值不能加单引号,否则到了前台就是字符串,永远为true
前台:  

Ext.define('Post', {
            extend: 'Ext.data.Model',
            fields: [{
                name: "text",
                convert: undefined
            }, {
                name: "id",
                convert: undefined
            }, {
                name: "check",
                convert: undefined
            }]
        });

//树中的checkcolumn行

{ text: 'checkcolumn', xtype: 'checkcolumn', flex: 1, dataIndex: 'check', stopSelection: false, }

过滤器

proAppStore.filterBy(function(record) {
                      return record.get('orgNameApp') == "IT";
                  });
