在ExtJS中将数据附加到GridPanel [英] Appending data to GridPanel in ExtJS

问题描述

我遇到一个看似简单的问题：将数据附加到我的ExtJS网格面板。我有一个网格面板，并设置了一些初始数据。

I'm stuck with a seemingly simple problem: appending data to my ExtJS Gridpanel. I have a gridpanel with some initial data set up.

var myData = [['data1','data2']];

var myReader = new Ext.data.ArrayReader({}, [
            {name: 'Col1'},
            {name: 'Col2'},
            );

var datastore = new Ext.data.Store({
            data: myData,
            reader: myReader
            });
grid = new Ext.grid.GridPanel({
            store: datastore,
   ...
   etc

这是一切正常的工作。现在我想定期向这个gridpanel添加新数据（有一个函数生成数组）
但是我没有任何想法？

This is all working fine.Now i would like to periodically append new data to this gridpanel (there is a function that is generating arrays of data). However I cant get this to work. Tried datastore.add, but to no avail.

推荐答案

解决方案

你传给datastore.add是什么？

What did you pass to datastore.add?

尝试这样：

datastore.add(new datastore.recordType({
    Col1: 'data3',
    Col2: 'data4'
}));
