前言

此示例说明如何通过 DataTables 实现整行编辑的功能，并且可以轻松自定义。请参阅 描述此示例的博客文章 了解更多信息。

实际示例

初始化代码

function restoreRow ( oTable, nRow )
{
	var aData = oTable.fnGetData(nRow);
	var jqTds = $('>td', nRow);
	
	for ( var i=0, iLen=jqTds.length ; i<iLen ; i++ ) {
		oTable.fnUpdate( aData[i], nRow, i, false );
	}
	
	oTable.fnDraw();
}

function editRow ( oTable, nRow )
{
	var aData = oTable.fnGetData(nRow);
	var jqTds = $('>td', nRow);
	jqTds[0].innerHTML = '<input type="text" value="'+aData[0]+'">';
	jqTds[1].innerHTML = '<input type="text" value="'+aData[1]+'">';
	jqTds[2].innerHTML = '<input type="text" value="'+aData[2]+'">';
	jqTds[3].innerHTML = '<input type="text" value="'+aData[3]+'">';
	jqTds[4].innerHTML = '<input type="text" value="'+aData[4]+'">';
	jqTds[5].innerHTML = '<a class="edit" href="">Save</a>';
}

function saveRow ( oTable, nRow )
{
	var jqInputs = $('input', nRow);
	oTable.fnUpdate( jqInputs[0].value, nRow, 0, false );
	oTable.fnUpdate( jqInputs[1].value, nRow, 1, false );
	oTable.fnUpdate( jqInputs[2].value, nRow, 2, false );
	oTable.fnUpdate( jqInputs[3].value, nRow, 3, false );
	oTable.fnUpdate( jqInputs[4].value, nRow, 4, false );
	oTable.fnUpdate( '<a class="edit" href="">Edit</a>', nRow, 5, false );
	oTable.fnDraw();
}

$(document).ready(function() {
	var oTable = $('#example').dataTable();
	var nEditing = null;
	
	$('#new').click( function (e) {
		e.preventDefault();
		
		var aiNew = oTable.fnAddData( [ '', '', '', '', '', 
			'<a class="edit" href="">Edit</a>', '<a class="delete" href="">Delete</a>' ] );
		var nRow = oTable.fnGetNodes( aiNew[0] );
		editRow( oTable, nRow );
		nEditing = nRow;
	} );
	
	$('#example a.delete').live('click', function (e) {

		oTable.fnDeleteRow( nRow );
	} );

			editRow( oTable, nRow );
			nEditing = nRow;
		}
		else if ( nEditing == nRow && this.innerHTML == "Save" ) {
			/* Editing this row and want to save it */
			saveRow( oTable, nEditing );
			nEditing = null;
		}
		else {
