下面通过本文给大家介绍下图中的treegrid如何实现？
要求：动态加载；级联勾选；通关类型判断显示包库/还是镜像（列有所不同，镜像共4列），勾选一个复选框，后面的复选框变为不可勾选状态。
下面是具体代码：
1，初始化treegrid，（其中有几个type列，是由后台人员提供的字段名，虽然我也不想弄一堆type...汗）
var root = 20543; //初始化产品树 function InitProductTreeGrid(rootid) { var type = '<%=Controler.ProductType%>'; var ishowPack = true; var ishowMirro = true; //1,包库；2，镜像 if (type == '1') { ishowPack = false; ishowMirro = true; } else { ishowPack = true; ishowMirro = false; }; $('#tt_Product').treegrid({ url: '../Handlers/Contract_ProductHandler.ashx', queryParams: { handlertype: "InitProductTreeGrid", ContractId: $('#ContractId').val(), CatalogId: rootid, pindex: $('#pindex').val() }, idField: 'id', width: 930, treeField: 'CatalogName', fitColumns: true, //宽度自适应窗口 rownumbers: false, //是否加行号 singleSelect: true, scrollbarSize: 0, //去除滚动条，否则右边最后一列会自动多处一块 columns: [[ { title: '产品列表', field: 'CatalogName', width: 210 }, { title: '产品ID', field: 'CatalogId', hidden: true }, { title: '父产品ID', field: 'ParentId', hidden: true }, { title: '父产品名称', field: 'ParentName', hidden: true }, { title: '产品类型', field: 'ProductType', hidden: true }, { title: '是否为子节点', field: 'isLeaf', hidden: true }, //备注：(1,是;0,否) { title: '是否为父节点', field: 'isParent', hidden: true }, { title: 'IsChecked', field: 'IsCheck', hidden: true }, { title: 'CurrentYearPrices', field: 'type1', hidden: true }, { title: 'MirrorCurrentYearPrices', field: 'type3', hidden: true }, { title: 'MirrorEarlyPrices', field: 'type4', hidden: true }, { title: 'MirrorPrevious3YearPrices', field: 'type5', hidden: true }, { field: 'CurrentYearPrices', title: '当前价格', width: 200, hidden: ishowPack, formatter: function (value, rec, index) { var d = '<input type="checkbox" name="CurrentYearPrices" catalogid="' + rec.CatalogId + '" ' + (rec.type1 == 'True' ?

'checked="checked"' : '') + ' id="MirrorCurrentYearPrices' + rec.CatalogId + '" onclick="showProductTree(this,/'MirrorCurrentYearPrices/',' + rec.CatalogId + ',' + rec.isParent + ');" parent="MirrorCurrentYearPrices' + rec.ParentId + '" isparent="' + rec.isParent + '" value="' + value + '" /> ' + value.substr(0, value.length - 2); //var d = '<span name="CurrentYearMirrorPrice" id="CurrentYearMirrorPrice' + rec.CatalogId + '" class="tree-checkbox tree-checkbox0">' + value + '</span>'; return d; } }, { field: 'MirrorPrevious3YearPrices', title: '前阶段价格', width: 200, hidden: ishowMirro, formatter: function (value, rec, index) { var d = '<input type="checkbox" name="MirrorPrevious3YearPrices" catalogid="' + rec.CatalogId + '" ' + (rec.type5 == 'True' ? 'checked="checked"' : '') + ' id="MirrorPrevious3YearPrices' + rec.CatalogId + '" onclick="showProductTree(this,/'MirrorPrevious3YearPrices/',' + rec.CatalogId + ',' + rec.isParent + ');" parent="MirrorPrevious3YearPrices' + rec.ParentId + '" isparent="' + rec.isParent + '" value="' + value + '" /> ' + value.substr(0, value.length - 2); return d; } }, { field: 'MirrorEarlyPrices', title: '早期价格', width: 200, hidden: ishowMirro, formatter: function (value, rec, index) { var d = '<input type="checkbox" name="MirrorEarlyPrices" catalogid="' + rec.CatalogId + '" ' + (rec.type4 == 'True' ? 'checked="checked"' : '') + ' id="MirrorEarlyPrices' + rec.CatalogId + '" onclick="showProductTree(this,/'MirrorEarlyPrices/',' + rec.CatalogId + ',' + rec.isParent + ');" parent="MirrorEarlyPrices' + rec.ParentId + '" isparent="' + rec.isParent + '" value="' + value + '" /> ' + value.substr(0, value.length - 2); return d; } }, { field: 'type0', title: '是否赠送', width: 200, formatter: function (value, rec, index) { //alert(rec.isPresent); var d = '<input type="checkbox" name="IsPresent" catalogid="' + rec.CatalogId + '" ' + (rec.type0 == 'True' ? 'checked="checked"' : '') + ' id="IsPresent' + rec.CatalogId + '" onclick="showProductTree(this,/'IsPresent/',' + rec.CatalogId + ',' + rec.isParent + ');" parent="IsPresent' + rec.ParentId + '" isparent="' + rec.isParent + '" value="0" /> '; return d; } } ]], loadFilter: function (data, parentId) { //逐层加载 function setData() { var todo = []; for (var i = 0; i < data.length; i++) { todo.push(data[i]); } while (todo.length) { var node = todo.shift(); if (node.children) { node.state = 'closed'; node.children1 = node.children; node.children = undefined; todo = todo.concat(node.children1); } } } setData(data); var tg = $(this); var opts = tg.treegrid('options'); opts.onBeforeExpand = function (row) { if (row.children1) { tg.treegrid('append', { parent: row[opts.idField], data: row.children1 }); row.children1 = undefined; tg.treegrid('expand', row[opts.idField]); } return row.children1 == undefined; }; return data; }, onLoadSuccess: function (row, data) { //alert(data[0].CatalogId) RelativeTreeGridCheck(); } }); };2，onLoadSuccess中的RelativeTreeGridCheck()级联方法
var parentcid; var ispid; var tempid; //父节点选中关联子节点选中 function RelativeTreeGridCheck() { var rows = $('#addProductTbl').find('.datagrid-view2 .datagrid-body .datagrid-btable tr'); for (var i = 0; i < rows.length; i++) { if ($(rows).eq(i).attr('node-id') != undefined) { parentcid = ""; ispid = -1; tempid = ""; catalogid = $(rows).eq(i).attr('node-id'); //alert(catalogid); var cols = $(rows).eq(i).find('td'); var fields = ''; for (var j = 0; j < cols.length; j++) { fields = $(cols).eq(j).attr('field'); //alert('fields:' + fields); switch (fields) { case 'CurrentYearPrices': case 'MirrorCurrentYearPrices': case 'MirrorPrevious3YearPrices': case 'MirrorEarlyPrices': case 'type0': if ($(cols).eq(j).find('div input:checked').length > 0) { parentcid = $(cols).eq(j).parent().find("td[field='CatalogId']").find('div').html(); ispid = $(cols).eq(j).parent().find("td[field='isParent']").find('div').html(); contractproducttype = $(cols).eq(j).find('div input').attr('name'); if (ispid == '1') { //获取checkbox对象 var obj = $(cols).eq(j).find('div input:checkbox'); //如果父节点选中，自己点也连带选中 showProductTree(obj, contractproducttype, parentcid, ispid) } } break; } } } } }function showProductTree(obj, catalogtype, id, isparent) { //alert(id.indexof('2')); if (isparent == 1) { //当前节点下包库子节点 //alert('$(obj).attr(checked)' + $(obj).attr('checked')); var state = $(obj).attr('checked') == undefined ? false : true; //alert('state:'+state+' id:'+id); //找出子节点 var nodes = $('input[name="' + catalogtype + '"][parent="' + catalogtype + id + '"]'); nodes.each(function () { //alert('$(this).attr(checked):' + $(this).attr('checked')); var curobjstate = $(this).attr('checked') == undefined ? false : true; disabledOthersCatalogType($(this), state, catalogtype) //alert('curobjstate:' + curobjstate + ' state:' + state + ' id:' + id + ' isparent: ' + $(this).attr('isparent')); if (curobjstate == state && $(this).attr('isparent') == '0') { //alert('leaf'); //如果当前节点的选中状态和父节点不同，并且当前节点不是父节点 $(this).attr('checked', state); $(this).prop('checked', state); } else { //alert('$(this).attr(catalogid)' + $(this).attr('catalogid') + '---$(this).attr(isparent)' + $(this).attr('isparent')); $(this).attr('checked', state); $(this).prop('checked', state); showProductTree($(this), catalogtype, $(this).attr('catalogid'), $(this).attr('isparent')) } if (state) { $(this).removeAttr('disabled'); } }); $(obj).prop('checked', state); disabledOthersCatalogType($(obj), state, catalogtype) } else { var state = $(obj).attr('checked') == undefined ? false : true; //alert(state); //alert(catalogtype); disabledOthersCatalogType($(obj), state, catalogtype) updateParentNodeCheckState($(obj), state, catalogtype) } } //修改其他产品类型的checkbox的只读状态 function disabledOthersCatalogType(obj, state, catalogtype) { $('input[catalogid="' + $(obj).attr('catalogid') + '"]').each(function () { if ($(this).attr('name') != catalogtype) { if (state) { $(this).attr('disabled', 'disabled'); } else { $(this).removeAttr('disabled'); } $(this).attr('checked', false).prop('checked', false); } }); } //查找上一层节点,修改其状态 function updateParentNodeCheckState(obj, state, catalogtype) { var pid = $(obj).attr('parent'); //如果父节点是根节点，则不再执行 if (pid == catalogtype + root || $('#' + pid).length == 0) return; var parent = $('#' + pid); if (!state) { //取消父节点的选中状态 parent.attr('checked', false) parent.prop('checked', false) } else { //alert('pid:'+pid+'---'+$('input[parent="' + pid + '"]:checked').length+'------'+$('input[parent="' + pid + '"]').length); //alert('checkedLen:' + $('input[parent="' + pid + '"]:checked').length + ' len:' + $('input[parent="' + pid + '"]').length); //子节点全部选中 if ($('input[parent="' + pid + '"]:checked').length == $('input[parent="' + pid + '"]').length) { parent.attr('checked', true); parent.prop('checked', true); } } //修改其他产品类型的checkbox的只读状态 disabledOthersCatalogType(parent, state, catalogtype) //继续查找上一层节点 updateParentNodeCheckState(parent, state, catalogtype) }3，由于是拼接比较繁杂，在此顺便再说一下传参代码
