EXT EditorGridPanel 中用复选框表示真假值,扩展官方示例
2009-09-26 00:00:00 来源:WEB开发网图片看不清楚?请点击这里查看原图(大图)。
在学习中Ext.grid.EditorGridPanel 的时候碰到一个知识点,如何用复选框来表示真假值,当然我们可以直接这样
Js代码
{
header : "管理员?",
dataIndex : 'manager',
width : 55,
editor : new Ext.form.CheckBox()
}
但是这样给我们的感觉不是很好,每次都要我们点击才会出现CheckBox,不能让他默认就显示在哪里,而且表示当前值?官方给了我们一个示例,下面是示例的源代码
Js代码

Ext.onReady(function(){
Ext.QuickTips.init();
function formatDate(value){
return value ? value.dateFormat('M d, Y') : '';
};
// shorthand alias
var fm = Ext.form;
// custom column plugin example
var checkColumn = new Ext.grid.CheckColumn({
header: "Indoor?",
dataIndex: 'indoor',
width: 55
});
// the column model has information about grid columns
// dataIndex maps the column to the specific data field in
// the data store (created below)
var cm = new Ext.grid.ColumnModel([{
id:'common',
header: "Common Name",
dataIndex: 'common',
width: 220,
editor: new fm.TextField({
allowBlank: false
})
},{
header: "Light",
dataIndex: 'light',

editor: new fm.DateField({
format: 'm/d/y',
minValue: '01/01/06',
disabledDays: [0, 6],
disabledDaysText: 'Plants are not available on the weekends'
})
},
checkColumn
]);
// by default columns are sortable
cm.defaultSortable = true;
// this could be inline, but we want to define the Plant record
// type so we can add records dynamically
var Plant = Ext.data.Record.create([
// the "name" below matches the tag name to read, except "availDate"
// which is mapped to the tag "availability"
{name: 'common', type: 'string'},
{name: 'botanical', type: 'string'},
{name: 'light'},
{name: 'price', type: 'float'}, // automatic date conversions
{name: 'availDate', mapping: 'availability', type: 'date', dateFormat: 'm/d/Y'},
{name: 'indoor', type: 'bool'}
]);
// create the Data Store
var store = new Ext.data.Store({
// load using HTTP
url: 'plants.xml',
// the return will be XML, so lets set up a reader
reader: new Ext.data.XmlReader({
// records will have a "plant" tag
record: 'plant'
}, Plant),
sortInfo:{field:'common', direction:'ASC'}
});
// create the editor grid

}

// trigger the data store load
store.load();
});
