比如,如果一个combo选了第一项,就把同一行的另外一个组件变成datefield,如果选了第二项,就把那个组件变成textfield。
API里说是用setEditor,但参数写的是field。
我这样写的话:
[code="java"] Ext.getCmp('quote_item_grid').columns[0].setEditor(new Ext.form.field.Text({value: 3}));[/code]
报错:column.getEditor is not a function
有好多这样问的,都说用setEditor,但好像都是3.3的,4.0是不是不一样了呢?
有人说在前面加一个参数columnNumber,我试了貌似也不行,报同样的错……
你发的那个网站,我没用明白 :oops: ,没找到怎么引入ext的样式文件。
[url]%EXT_HOME%\ext-4.0.2-gpl\ext-4.0.2\examples\grid\array-grid.js[/url]在你的ext的包下面这个路径的这个文件内容换成我这个,然后你浏览array-grid.html看看。

这个做的是第一列的editor是个combo,选第一项的话,第二列的editor为文本,选第二项,第二列的editor为日期。
你的这个columns选错了吧,
应该是改变某一列的editor,比如这样:
[code="java"]{
text : 'Company',
flex : 1,
sortable : false,
dataIndex: 'company',
editor:{xtype:'numberfield'}
},
{
id:'dg',
text : 'Price',
width : 75,
sortable : true,
renderer : 'usMoney',
dataIndex: 'price',
editor:{xtype:'numberfield'}
}[/code]
现在有2列,editor都是数字输入框。在第一个editor被编辑时触发事件,在事件中改变第二个editor的类型为文本输入框。
[code="java"]plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1,
listeners:{
'edit':function(e,s){
if(s.field=="company"){
alert(1);
Ext.getCmp('dg').setEditor(new Ext.form.field.Text({value: 3}));
}
}
}
})
][/code]
具体的这个edit事件传进来的参数[color=red]e,s[/color]你可以查一下API中Ext.grid.plugin.CellEditing这个类的edit事件。就不一一列举了。
这里没有按照你的要求根据comboBox的选项来改变editor的类型,正好你自己练习下哈 :idea:
[code="java"]
text : 'Company',
flex : 1,
sortable : false,
dataIndex: 'company',
editor:{xtype:'combo',
store: states,
displayField: 'name',
valueField: 'abbr',
listeners:{
'change':function(ts){
var text =this.value;
if(text=='AL'){
Ext.getCmp('dg').setEditor(new Ext.form.field.Text({value: 3}));
Ext.getCmp('dg').removeListener('edit');
}
if(text=='AK'){
Ext.getCmp('dg').setEditor(new Ext.form.field.Date());
}
}
}
}
},
{
id:'dg',
text : 'Price',
width : 75,
sortable : true,
dataIndex: 'price',
editor:{xtype:'numberfield'}
}
[/code]
在combo的edit事件中改变列的editor。现在存在个问题,如果这个id为dg的列开始不是日期类型,那么editor改变为日期类型,我不知道该怎么给它格式化。。。
[code="java"]Ext.getCmp('dg').removeListener('edit'); [/code]
这句话不要。。。
图片怎么上传啊。。 :oops: 是要上传到网上图片库在给链接么。
[img]C:\Users\lenovo\Desktop\未命名.jpg[/img]
[img]C:\Users\lenovo\Desktop\未命名1.jpg[/img]
[code="java"]Ext.getCmp('dg').setEditor(new Ext.form.field.Text({value:4}));[/code]这个文本给个值。。
我发的图片能看到么?日历的效果出来了么?
