解决：使用layui.treeTable.updateNode,更新表格数据后，done里面的事件丢失问题

1. 背景

在给树形表格添加行点击事件，并且只更新当前行数据。 treeTable.updateNode("SpeProjListId", result.LAY_DATA_INDEX, result);更新数据后，点击事件失效。

1. 给字段绑定事件：

class="link_a link_style"

              , {field: 'Name', title: '预算专项名称/项目名称', minWidth: 240, rowspan: 2, templet: function (d) {if (d.IsParent) {return `<a  href="javascript:;"class="link_a link_style internal_link"data-type="speProjCode"data-value="${d.Code}"data-name="${d.CtrlObjectValue1Name}">${d.CtrlObjectValue1Name}</a>`;} else {return `<a  href="javascript:;"class="link_a link_style internal_link"data-type="projCode"data-name="${d.Name}"data-value="${d.ExpBudProjectId}">${d.Name}</a>`;}}}

2. done里面的点击事件：click

                treeTable.render({elem: '#SpeProjInfoSel', id: "SpeProjListId", method: "post", height: 'full-300', even: true, data: self.SpecProjInfoList, autoSort: false, page: false, css: [// 对开启了编辑的单元格追加样式'.layui-table-view td[data-edit]{color: #16B777;}'].join(''), cols: [cols, fundCols], limit: 20, tree: {view: {expandAllDefault: true,},customName: {children: "ProjInfoList",name: "Code",isParent: "IsParent"},data: {rootPid: "",},callback: {onExpand: function () {format.init();}}}, done: function (res) {format.init();form.render();$(".expandAll").on("click", function () {treeTable.expandAll("SpeProjListId", true);})$(".foldAll").on("click", function () {treeTable.expandAll("SpeProjListId", false);});urp.callbackFunction.Remark_callBack = function (value, tag) {var indexArr = tag.split(",");var indexs = indexArr[1].split("-");var list = self.SpecProjInfoList[indexs[0]].ProjInfoList[indexs[1]];if (indexArr[0] == "Remark") {list.Remark = value;}}//预算专项抽屉式弹窗(父) 这里的事件触发$(".link_a").click(function () {module.CustomFunction.configSpecInfo($(this).data("value"), $(this).data("name"), $(this).data("type"), $(this).attr("folder-width"));return;});}});

3. 点击事件的回调函数：

urp.callbackFunction.RefreshTable_Link_a=function(){};

函数里面使用了treeTable.updateNode("SpeProjListId", result.LAY_DATA_INDEX, result);更新数据。此时点击事件丢失。

4. 解决方法： table.reload('SpeProjListId', {});重新渲染done里面的事件。

     CustomFunction: {configSpecInfo: function (value, valueName, type, folderWidth) {var paramData = {};if (type == "speProjCode") {paramData = module.SpecProjInfoList.find(speInfo => { return speInfo.CtrlObjectValue1 == value });}const area = folderWidth != undefined ? [folderWidth, '100%'] : (type == "projCode" || type == "projAppCode" ? ['70%', '100%'] : ['30%', '100%']);urp.callbackFunction.RefreshTable_Link_a = function (data) {//把数据塞到预算专项里面var result = module.SpecProjInfoList.find(obj => obj.Code == data.CtrlObjectValue1);result = $.extend(result, data)module.SpecProjInfoList = module.SpecProjInfoList.filter(speInfo => { return speInfo.Code != data.CtrlObjectValue1 });module.SpecProjInfoList = module.SpecProjInfoList.concat(result);format.init();
//使用updateNode渲染行数据treeTable.updateNode("SpeProjListId", result.LAY_DATA_INDEX, result);table.reload('SpeProjListId', {});format.init();form.render();}let linkInfo = module.CustomFunction.getLinkHref(type, value)urp.openWindow({href: linkInfo.href,title: linkInfo.title + ` - ${valueName}`,callbackFunction: 'RefreshTable_Link_a',area: area,target: 'parent',queryString: "viewMode=edit",ParamData: paramData,initOpt: {offset: 'r',anim: 'slideLeft',target: 'self',shade: 0.1,shadeClose: true,},})},getLinkHref: (type, value) => {switch (type) {case "speProjCode":return { href: `/BG/ExpBudCtrl/ExpBudProjSpeProjDetail?CtrlObjectValue1=${value}&IsDrawersWindow=true`, title: "预算专项信息" }case "projCode":return { href: `/BG/ExpBudProj/ExpBudProjectDetailR?ExpBudProjectId=${value}&IsDrawersWindow=true`, title: "项目预算信息" }case "projAppCode":return { href: `/PL/ProjectApp/ProjectAppDetailR?ProjCode=${value}&IsDrawersWindow=true`, title: "项目申报书信息" }}},}
