easyui datagrid 批量编辑和提交

前台主要代码：

$.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：

//设置请求编码
req.setCharacterEncoding("UTF-8");
//获取编辑数据这里获取到的是json字符串
String deleted = req.getParameter("deleted");
String inserted = req.getParameter("inserted");
String updated = req.getParameter("updated");

if(deleted != null){
//把json字符串转换成对象
List<Bean> listDeleted = JSON.parseArray(deleted, Bean.class);
//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 = JSON.parseArray(inserted, Bean.class);
}

if(updated != null){
//把json字符串转换成对象
List<Bean> listUpdated = JSON.parseArray(updated, Bean.class);
}

Bean.java

public class Bean {
private String code;
private String name;
private Double price;
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Double getPrice() {
return price;
}
public void setPrice(Double price) {
this.price = price;
}
}

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;
}

里面用到的JSON.stringify，主要是把对象转换为字符串的作用,原代码在这里

注意下载这个js后，如果运行出错就去掉最后几行代码。如下删除

if (!Object.prototype.toJSONString) {
Object.prototype.toJSONString = function (filter) {
return JSON.stringify(this, filter);
};
Object.prototype.parseJSON = function (filter) {
return JSON.parse(this, filter);
};
}
