Question

I am beginning with ExtJS. I am trying to read a value from a cell that is selected
I use an EditorGrid and the store looking like that :

my_store = new Ext.data.JsonStore({
    root:  topics ,
    totalProperty:  totalCount ,
    idProperty:  details_id ,

    fields: [
        {name :  index ,    type :  int },
        {name :  inactive , type :  int },
        {name :  c_1 ,      type :  string },
        {name :  c_2 ,      type :  string },
        {name :  c_3 ,      type :  string },
        {name :  c_4 ,      type :  string }
    ],
    proxy: new Ext.data.ScriptTagProxy({
        url:  my_proxy_url 
    })
});

到目前为止,这是我用来检索选定牢房的浏览器和栏目:

var column = grid.getSelectionModel().selection.cell[0];
var row    = grid.getSelectionModel().selection.cell[1];

我怎么能够读到电网中某个选定电池的价值并改变这一价值?

Answer 1

这完全取决于你的甄选模式。缩略语您可以取得选定行文的记录,因此:

var sel_model = grid.getSelectionModel();
var record = sel_model.getSelection()[0];

那么,你们需要的是使用一套(......)方法:

record.set("c_1","Test");

当然,有<条码>EditorGridPanel,你改称编辑,以控制而不是直接编辑。

您的答复

这完全取决于你的甄选模式。缩略语您可以取得选定行文的记录,因此:

var sel_model = grid.getSelectionModel();
var record = sel_model.getSelection()[0];

然后,你需要的是使用<代码>()方法:

record.set("c_1","Test");

当然,有一个主编GridPanel的编辑,你将重新编辑成控制,而不是直接编辑。

this works, But what if i want to accesses the value of cell by using column value (e.g. 4 or 5) instead of column name. Is it possible to do the same
