jqueryEasyuiDatagrid实现批量操作（编辑，删除，添加）有时候我们的后台系统表单⽐较复杂，做过进销存或者⼀些销售订单的都应该有过感觉。
虽然Easyui Datagrid提供了⾏内编辑，但是不够灵活，但是我们稍微修改⼀下来达到批量编辑，批量删除，批量添加的效果。
现在我们来看看原的编辑：来⾃Easyui 1.5.1的Demo <demo/datagrid/rowediting.html>
接下来，我们主要是要⾼度⾃由的编辑实现：
1.可以同时追加多⾏
2.追加的⾏可以是任何位置
3.可以随时进⾏编辑任意位置的⾏
4.保存再统⼀验证
实现
在原有的rowediting.html进⾏修改！
第⼀：修改⾏的点击事件（点击⾏的时候进⼊编辑状态）
function onClickCell(index, field){
if (editIndex != index) {
if (endEditing()) {
$('#dg').datagrid('selectRow', index)
.datagrid('beginEdit', index);
var ed = $('#dg').datagrid('getEditor', { index: index, field: field });
if (ed) {
($(ed.target).data('textbox') ? $(ed.target).textbox('textbox') : $(ed.target)).focus();
}
editIndex = index;
} else {
setTimeout(function () {
$('#dg').datagrid('selectRow', editIndex);
}, 0);
}
}
}
第⼆：删除事件（点击顶部菜单Remove删除选中的⾏，点击列表的-号，删除减号⾏）
function removeit(){
if (editIndex == undefined){return}
$('#dg').datagrid('selectRow', editIndex);
$('#dg').datagrid('cancelEdit', editIndex)
.datagrid('deleteRow', editIndex);
editIndex = undefined;
}
第三：添加事件，点击菜单的Append和+号
function append(){
var index = $('#dg').datagrid('getRowIndex', $('#dg').datagrid('getSelected'));
if (index == -1)
index = 0;
$("#dg").datagrid("insertRow", {
index: index+1,
row: {oper: "<a href='javascript:append()'>+<a> <a href='javascript:removeit()'>-<a>",status:'P'}
});
}
第四：保存（获得操作的记录，包括，增加，修改，删除中的记录）
function accept(){
if (endEditing()){
var $dg = $('#dg');
var rows = $dg.datagrid('getChanges');
if (rows.length) {
var inserted = $dg.datagrid('getChanges', "inserted");
var deleted = $dg.datagrid('getChanges', "deleted");
var updated = $dg.datagrid('getChanges', "updated");
var effectRow = new Object();
if (inserted.length) {
effectRow["inserted"] = JSON.stringify(inserted);
}
if (deleted.length) {
effectRow["deleted"] = JSON.stringify(deleted);
}
if (updated.length) {
effectRow["updated"] = JSON.stringify(updated);
}
//alert(inserted);
//alert(deleted);
//alert(updated);
}
}
//$.post("/Home/Commit", effectRow, function (rsp) {
// if (rsp) {
//  $dg.datagrid('acceptChanges');
//  bindData();
// }
//}, "JSON").error(function () {
// $.messager.alert("提⽰", "提交错误了！");
//});
}
最后我们可以获得，上⾯操作的，所有：添加的⾏，删除的⾏，更新的⾏！把数据传⼊到数据后台进⾏处理！最后你还需要对数据进⾏循环校验，可以获得数据，在控制台输出：
console.log(inserted);
console.log(deleted);
console.log(updated);
总结：
