[转]easyui datagrid 批量编辑和提交
web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++) { $dg.datagrid('endEdit', i); } } }); </script> <body> <table id="dg" title="批量操作"></table> </body> </html>
后台commit接收类：
Java版本处理
//设置请求编码 req.setCharacterEncoding("UTF-8"); //获取编辑数据 这里获取到的是json字符串 String deleted = req.getParameter("deleted"); String inserted = req.getParameter("inserted"); String updated = req.getParameter("updated"); if(deleted != null){ //把json字符串转换成对象 List<Bean> listDeleted = JSON.parseArray(deleted, Bean.class); //TODO 下面就可以根据转换后的对象进行相应的操作了 } if(inserted != null){ //把json字符串转换成对象 List<Bean> listInserted = JSON.parseArray(inserted, Bean.class); } if(updated != null){ //把json字符串转换成对象 List<Bean> listUpdated = JSON.parseArray(updated, Bean.class); }
Bean.java
public class Bean { private String code; private String name; private Double price; public String getCode() { return code; } public void setCode(String code) { this.code = code; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Double getPrice() { return price; } public void setPrice(Double price) { this.price = price; } }
PHP版本处理：
<?php if(isset($_POST["deleted"])){ $deleted = $_POST["deleted"];//这里获取到的是一个json数组样子字符串，eg：[{code:'1',name:'name',price:323},{..},....] $listDeleted = json_decode($deleted); //把这个json数组转化成array对象 } if(isset($_POST["inserted"])){ $inserted = $_POST["inserted"]; $listInserted = json_decode($inserted); } if(isset($_POST["updated"])){ $updated = $_POST["updated"]; $listUpdated = json_decode($updated); }
ASP.NET MVC3版本：
//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; }
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); }; }
