前言

有時候咱們的後臺系統表單比較複雜，作過進銷存或者一些銷售訂單的都應該有過感受javascript

雖然Easyui Datagrid提供了行內編輯，可是不夠靈活，可是咱們稍微修改一下來達到批量編輯,批量刪除,批量添加的效果css

如今咱們來看看原的編輯:來自Easyui 1.5.1的Demo <demo/datagrid/rowediting.html>html

接下來，咱們主要是要高度自由的編輯實現：java

1.能夠同時追加多行
2.追加的行能夠是任何位置
3.能夠隨時進行編輯任意位置的行
4.保存再統一驗證

實現

在原有的rowediting.html進行修改！jquery

第一：修改行的點擊事件（點擊行的時候進入編輯狀態）

    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：刪除事件（點擊頂部菜單Remove刪除選中的行，點擊列表的-號，刪除減號行）

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，點擊菜單的Append和+號

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（得到操做的記錄，包括，增長，修改，刪除中的記錄）

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", "提交錯誤了！");
            //});
        }

最後咱們能夠得到，上面操做的，全部：添加的行，刪除的行，更新的行！把數據傳入到數據後臺進行處理！json

最後你還須要對數據進行循環校驗,能夠得到數據，在控制檯輸出：app

console.log(inserted);
console.log(deleted);
console.log(updated);ide

總結：
