前台主要代码：
<script type="text/javascript">
$(function() {
var $dg = $("#dg");
$dg.datagrid({
url : "servlet/list",
width : 700,
height : 250,
columns : [ [ {
field : ‘code‘,
title : ‘Code‘,
width : 100,
editor : "validatebox"
}, {
field : ‘name‘,
title : ‘Name‘,
width : 200,
editor : "validatebox"
}, {
field : ‘price‘,
title : ‘Price‘,
width : 200,
align : ‘right‘,
editor : "numberbox"
} ] ],
toolbar : [ {
text : "添加",
iconCls : "icon-add",
handler : function() {
$dg.datagrid(‘appendRow‘, {});
var rows = $dg.datagrid(‘getRows‘);
$dg.datagrid(‘beginEdit‘, rows.length - 1);
}
}, {
text : "编辑",
iconCls : "icon-edit",
handler : function() {
var row = $dg.datagrid(‘getSelected‘);
if (row) {
var rowIndex = $dg.datagrid(‘getRowIndex‘, row);
$dg.datagrid(‘beginEdit‘, rowIndex);
}
}
}, {
text : "删除",
iconCls : "icon-remove",
handler : function() {
var row = $dg.datagrid(‘getSelected‘);
if (row) {
var rowIndex = $dg.datagrid(‘getRowIndex‘, row);
$dg.datagrid(‘deleteRow‘, rowIndex);
}
}
}, {
text : "结束编辑",
iconCls : "icon-cancel",
handler :endEdit
}, {
text : "保存",
iconCls : "icon-save",
handler : function() {
endEdit();
if ($dg.datagrid(‘getChanges‘).length) {
var inserted = $dg.datagrid(‘getChanges‘, "inserted");
var deleted = $dg.datagrid(‘getChanges‘, "deleted");
var updated = $dg.datagrid(‘getChanges‘, "updated");
var effectRow = new Object();
if (inserted.length) {
effectRow["inserted"] = JSON.stringify(inserted);
}
if (deleted.length) {
effectRow["deleted"] = JSON.stringify(deleted);
}
if (updated.length) {
effectRow["updated"] = JSON.stringify(updated);
}
$.post("servlet/commit", effectRow, function(rsp) {
if(rsp.status){
$.messager.alert("提示", "提交成功！");
$dg.datagrid(‘acceptChanges‘);
}
}, "JSON").error(function() {
$.messager.alert("提示", "提交错误了！");
});
}
}
} ]
});
function endEdit(){
var rows = $dg.datagrid(‘getRows‘);
for ( var i = 0; i < rows.length; i++) {
$dg.datagrid(‘endEdit‘, i);
}
}
});
</script>
<body>
<table id="dg" title="批量操作"></table>
</body>
</html>
后台commit接收类：
//获取编辑数据 这里获取到的是json字符串
string deleted = Request.Form["deleted"];
string inserted = Request.Form["inserted"];
string updated = Request.Form["updated"];
if(deleted != null){
//把json字符串转换成对象
List<Bean> listDeleted = JsonDeserialize<List<Bean>>(deleted);
//TODO 下面就可以根据转换后的对象进行相应的操作了
}
if(inserted != null){
//把json字符串转换成对象
List<Bean> listInserted = JsonDeserialize<List<Bean>>(inserted);
}
if(updated != null){
//把json字符串转换成对象
List<Bean> listUpdated = JsonDeserialize<List<Bean>>(updated);
}
JsonDeserialize方法：
private T JsonDeserialize<T>(string jsonString)
{
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
T obj = (T)ser.ReadObject(ms);
return obj;
}
