DataTables-1.10.6 ajax数据源表格行增删无效问题

bootstrap v3+DataTables-1.10.6

ssp ajax数据源表格添加删除行,重新进行ajax请求导致添加行被刷新,

重写row  api中的add  remover方案,以达到需要效果,并对reload方案做额外复原处理

row().remove()和rows.remove()在源码中合并,但使用的是匿名内部方法

_api_registerPlural( 'rows().remove()', 'row().remove()', function () {..}

但对外提供的register方案中并不支持合并,虽然方法体一样,但拆开写,当然可以抽取.

以下为重写方案.

$.fn.dataTable.Api.register('row().add()', function(row) {
	if (row instanceof $ && row.length) {
		row = row[0];
	}
	var rows = this.iterator('table', function(settings) {
		// 重写,使SSP AJAX数据源表格添加行不会使用URL重刷
		settings.bAjaxDataGet = false;
		// 重写 end
		if (row.nodeName && row.nodeName.toUpperCase() === 'TR') {
			return _fnAddTr(settings, row)[0];
		}
		return $.fn.dataTableExt.internal._fnAddData(settings, row);
	});
	// Return an Api.rows() extended instance, with the newly added row selected
	return this.row(rows[0]);
});
$.fn.dataTable.Api.register('rows.add()', function(rows) {
	var newRows = this.iterator('table', function(settings) {
		var row, i, ien;
		var out = [];
		for (i = 0, ien = rows.length; i < ien; i++) {
			row = rows[i];
			// 重写,使SSP AJAX数据源表格添加行不会使用URL重刷
			settings.bAjaxDataGet = false;
			// 重写 end
			if (row.nodeName && row.nodeName.toUpperCase() === 'TR') {
				out.push($.fn.dataTableExt.internal._fnAddTr(settings, row)[0]);
			} else {
				out.push($.fn.dataTableExt.internal._fnAddData(settings, row));
			}
		}
		return out;
	}, 1);
	// Return an Api.rows() extended instance, so rows().nodes() etc can be used
	var modRows = this.rows(-1);
	modRows.pop();
	modRows.push.apply(modRows, newRows.toArray());
	return modRows;
});
$.fn.dataTable.Api.register('row().remove()', function() {
	var that = this;
	return this.iterator('row', function(settings, row, thatIdx) {
		var data = settings.aoData;
		data.splice(row, 1);
		// Update the _DT_RowIndex parameter on all rows in the table
		for ( var i = 0, ien = data.length; i < ien; i++) {
			if (data[i].nTr !== null) {
				data[i].nTr._DT_RowIndex = i;
			}
		}
		// Remove the target row from the search array
		var displayIndex = $.inArray(row, settings.aiDisplay);
		// 重写,使SSP AJAX数据源表格添加行不会使用URL重刷
		settings.bAjaxDataGet = false;
		// 重写 end
		// Delete from the display arrays
		$.fn.dataTableExt.internal._fnDeleteIndex(settings.aiDisplayMaster, row);
		$.fn.dataTableExt.internal._fnDeleteIndex(settings.aiDisplay, row);
		$.fn.dataTableExt.internal._fnDeleteIndex(that[thatIdx], row, false); // maintain local indexes
		// Check for an 'overflow' they case for displaying the table
		$.fn.dataTableExt.internal._fnLengthOverflow(settings);
	});
});
$.fn.dataTable.Api.register('rows().remove()', function() {
	var that = this;
	return this.iterator('row', function(settings, row, thatIdx) {
		var data = settings.aoData;
		data.splice(row, 1);
		// Update the _DT_RowIndex parameter on all rows in the table
		for ( var i = 0, ien = data.length; i < ien; i++) {
			if (data[i].nTr !== null) {
				data[i].nTr._DT_RowIndex = i;
			}
		}
		// Remove the target row from the search array
		var displayIndex = $.inArray(row, settings.aiDisplay);
		// 重写,使SSP AJAX数据源表格添加行不会使用URL重刷

		// Check for an 'overflow' they case for displaying the table
		$.fn.dataTableExt.internal._fnLengthOverflow(settings);
	});
});
$.fn.dataTable.Api.register('ajax.reload()', function(callback, resetPaging) {
	var __reload = function(settings, holdPosition, callback) {
		// Use the draw event to trigger a callback
		if (callback) {
			var api = new $.fn.dataTable.Api(settings);

		if ($.fn.dataTableExt.internal._fnDataSource(settings) == 'ssp') {
