ligerui 表格树中 Uncaught TypeError: p.tree.isParent is not a function

 

 var requestUrl = "/Request/Fork.ashx?action=Check"&temp=" + new Date();
             grid = $("#maingrid").ligerGrid({
                height: '100%',
                columns: [
                { display: 'parent_id', name: 'parent_id', width: 110 , hide: true  }, 
                { display: 'SKU', name: 'User_code', width: 150 },

                url: requestUrl, showTitle: false,
                 rownumbers: false,
               // alternatingRow: false,
                tree: { columnName: 'User_code'  },  //以树形显示的字段id ,或者name值也可以
                onAfterShowData: function() {
                    //var l = $(".l-grid-tree-link-open").length;
                    //for (var i = l - 1; i >= 0; i--)
                    //    $(".l-grid-tree-link-open")[i].click();
                    collapseAll();

在使用  ligerui的  表格 Tree中 首次加载没问题，查询后显示 

Uncaught TypeError: p.tree.isParent is not a function
at $.ligerui.controls.Grid._getTreeCellHtml (VM10446 ligerui.all.js:12085)

定位到JS中可见 p.tree.isParent， 

 

 

 

 

通过 log 发现   JSON.stringify(p.tree) 具体内容，发现需要在  tree: { columnName: 'User_code'    ,isExtend:true,"childrenName":"children",},  

 

 

然后JS 修改：

 

 

if (p.tree.isParent == undefined) {
p.tree.isParent = function (rowData) {
var exist = p.tree.childrenName in rowData;
return exist;
}

}
var isParent = (p.tree.isParent == undefined ?
function (rowData) {
var exist = p.tree.childrenName in rowData;
return exist;
}
: p.tree.isParent(rowdata)); //原始
