easyui datagrid 表格内改变数据，改变其他单元格数据

也不全算是原创，看了网上不少资料
最近客户需要录入数据的时候按照excel中的方式，整体录入完毕后保存，
是用easyuidatagrid的时候遇到问题，
1）在进入datagrid的编辑状态后，使用普通的例如var rowdata = $("#demowells").datagrid("selectRow",editIndex);
是不管用的，只有在onBeginEdit:function()中使用是有用的
2）新增一行
$('#demowells').datagrid('insertRow', {
index: index,
row:{
// status:'P'
}

});
3）如果让datagrid的某行可以编辑需要
$('#demowells').datagrid('beginEdit',index);

4）新增一行可编辑的行，需要新增一行，选中一行，可编辑一行
function insert(){
var flag = endEditing();
if(!endEditing())return;
var row = $('#demowells').datagrid('getSelected');
if (row){
var index = $('#demowells').datagrid('getRowIndex', row);
} else {
index = 0;
}
$('#demowells').datagrid('insertRow', {
index: index,
row:{
// status:'P'
}
});
$('#demowells').datagrid('selectRow',index);
$('#demowells').datagrid('beginEdit',index);
editIndex = index;

}
5）在可编辑状态下，onClickRow  ，onClickCell是不会触发的
6）让某行的某列可编辑需要，在字段中加editor:属性
{field:'demoId',title:'demoId',width:100,editor:'textbox'},

7）需要触发某行的某列编辑后，触发该行的其他列数据改变，需要在onBeginEdit中使用
var rowdata2 = $("#demowells").datagrid("getEditors",rowIndex);

rowdata2[index]获取可编辑单元格
var products = [
{productid:'FI-SW-01',name:'Koi'},
{productid:'K9-DL-01',name:'Dalmation'},
{productid:'RP-SN-01',name:'Rattlesnake'},
{productid:'RP-LI-02',name:'Iguana'},
{productid:'FL-DSH-01',name:'Manx'},
{productid:'FL-DLH-02',name:'Persian'},
{productid:'AV-CB-01',name:'Amazon Parrot'}

];
8）触发行内combobox的onSelect事件，不能使用普通的onSelelct方法，而需要在onBeginEdit中使用
9）建议不要有多行可编辑，只有一行可编辑
var editormodel = rowdata2[4];
editorProduct.target.combobox({
onSelect:function(obj){
editorOther.target.textbox('setValue',obj.name);
editormodel.target.combobox('setValue',obj.productid);
}
});
$(function(){
  $("#demowells").datagrid({
  title:'Editable DataGrid',
iconCls:'icon-edit',
width:660,
height:250,
singleSelect:true,
idField:'demoId',
columns:[[    
{field:'demoId',title:'demoId',width:100,editor:'text'},

        {field:'productid',title:'product',width:100,editor:'text',
        formatter:function(value){
for(var i=0; i<products.length; i++){
if (products[i].productid == value) return products[i].name;
}
return value;
},
editor:{
type:'combobox',
options:{
valueField:'productid',
textField:'name',
data:products,
required:true
}
}
        },    
        {field:'demoOther',title:'demoOther',width:100,align:'right',editor:'textbox'},
        {field:'modelid',title:'model',width:100,editor:'text',
        formatter:function(value){
for(var i=0; i<products.length; i++){
if (products[i].productid == value) return products[i].name;
}
return value;
},
editor:{
type:'combobox',
options:{
valueField:'productid',
textField:'name',
data:products,
required:true
}
}
        },
        {field:'action',title:'Action',width:80,align:'center',
formatter:function(value,row,index){
console.log(row);
console.log(index);
if (row.editing){
var s = '<a href="#" onclick="saverow(this)">Save</a> ';
var c = '<a href="#" onclick="cancelrow(this)">Cancel</a>';
return s+c;
} else {
var e = '<a href="#" onclick="editrow(this)">Edit</a> ';
var d = '<a href="#" onclick="deleterow(this)">Delete</a>';
return e+d;
