我是ExtJs的新手,我试图以这种方式显示复选框组
grid
grid
我有以下代码
Ext.onReady(function() { var ct = Ext.create('Ext.container.Viewport',{ layout: 'border',defaults: { collapsible: true,split: true },items: [{ title: 'Tasks',region: 'west',margins: '5 0 0 0',cmargins: '5 5 0 0',width: '50%',scrollable: true,bodyStyle: 'padding:10px',html: MyTest.description },{ collapsible: false,region: 'center',items: [{ xtype: 'grid',id: 'MyGridPanel',title: 'Test Grid',store: { fields: ['name','permissions'],proxy: { type: 'memory',reader: {type: 'json'} },data: [{ name: 'Farms',permissions:{ 'manage': 1,'clone': 1,'launch': 0,'terminate': 0,'not-owned-farms': 0 } },{ name: 'Alerts',permissions:null },{ name: 'Servers',{ name: 'Events and notifications',{ name: 'Statistics',{ name: 'Roles',permissions:{ 'manage':1,'clone':0,'bundletasks':0 } },{ name: 'Scripts',permissions:{ 'manage':0,'execute':0,'fork':0 } }] },columns: [{ text: 'Name',width: 200,dataIndex: 'name' },{ text: 'Permissions',dataIndex: 'permissions',// I need to insert here a checkbox groups for elements that have permissions I guess. So what should I use here - renderer,handle? }],}] }] });
那我应该用什么呢?例如,如果我使用渲染器(不确定是否可以使用它),我可以收到复选框的所有数据(参见下面的代码),但我不知道如何渲染它.
renderer: function(value,meta,rec,rowIdx,colIdx,store,view) { var checkboxconfigs = []; for (var variable in value) { checkboxconfigs.push({ boxLabel: variable,name: variable,inputValue: value[variable],checked: value[variable] }) } var checkboxes = new Ext.form.CheckboxGroup({ id:'chkGroup',fieldLabel: 'Permissions',columns: 1,items: checkboxconfigs }); // return WHAT?; }
我很感激你的帮助!
解决方法
解:
如果要渲染值,请尝试使用此列定义:
{ text: 'Permissions',renderer: function(value,cell) { var s = ''; for (var index in value) { s = s + '<input type="checkbox" '; if (value[index] == 1) { s = s + 'checked'; }; s = s + '>' + index; } return s; } }
笔记:
用ExtJS 4.2测试.
