您好,登錄后才能下訂單哦!
有時候我們的后臺系統表單比較復雜,做過進銷存或者一些銷售訂單的都應該有過感覺。
雖然Easyui Datagrid提供了行內編輯,但是不夠靈活,但是我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。
現在我們來看看原的編輯:來自Easyui 1.5.1的Demo <demo/datagrid/rowediting.html>
接下來,我們主要是要高度自由的編輯實現:
1.可以同時追加多行
2.追加的行可以是任何位置
3.可以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!
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(獲得操作的記錄,包括,增加,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!"); //}); }
最后我們可以獲得,上面操作的,所有:添加的行,刪除的行,更新的行!把數據傳入到數據后臺進行處理!
最后你還需要對數據進行循環校驗,可以獲得數據,在控制臺輸出:
console.log(inserted); console.log(deleted); console.log(updated);
總結:
最后完整代碼:(替換Easyui的rowediting.html可運行效果)
