当节点不应该开始扩展时

Question

当我在jqGrid中加载我的treegrid时，我想让我的数据崩溃，但即使我在每一行上都有“expanded：false”，叶子也不会隐藏。我必须在三角形上单击两次才能折叠它们。

如果是jqGrid错误，有没有办法以编程方式折叠所有行？

我正在使用jqgrid 4.5.2

我的网格

$("#InventorySummary").jqGrid({
 datatype: 'jsonstring',
 datastr: summary,
 colNames: ['ID', 'SearchId', 'Type', 'NOM', 'NBRE DE BILLOTS', 'VOL. MOYEN', 'VOLUME  EN PMP', 'TAUX/MPMP', 'MONTANT EN $ USA'],
 colModel: [
    { name: 'ID', index: 'ID', hidden: true, key: true },
    { name: 'SearchID', index: 'SearchID', hidden: true },
    { name: 'Type', index: 'Type', hidden: true },
    { name: 'Name', index: 'Name' },
    { name: 'Count', index: 'Count' },
    { name: 'PmpAvg', index: 'PmpAvg' },
    { name: 'PmpSum', index: 'PmpSum' },

    { name: 'Cost', index: 'Cost' },
 ],
 caption: "Inventory",
 height: 'auto',
 footerrow: true,
 treeGrid: true,
 treeGridModel: 'adjacency',
 ExpandColumn: 'Name',
 gridComplete: function () {
    var grid = $("#InventorySummary");
    var data = grid.jqGrid('getGridParam', 'data').filter(function (x) {
       return x.parent === null;
    });
    var count = data.reduce(function (x, y) { return x + y.Count }, 0);
    var pmpSum = data.reduce(function (x, y) { return x + y.PmpSum }, 0);
    var cost = data.reduce(function (x, y) { return x + y.Cost }, 0);
    grid.jqGrid('footerData', 'set', { Name: "TOTAUX" });
    grid.jqGrid('footerData', 'set', { Count: count });
    grid.jqGrid('footerData', 'set', { PmpAvg: (pmpSum / count) | 0 });
    grid.jqGrid('footerData', 'set', { PmpSum: pmpSum });
    grid.jqGrid('footerData', 'set', { Mpmp: Math.round(((cost / pmpSum) * 1000) * 100) / 100 });
    grid.jqGrid('footerData', 'set', { Cost: cost });
 },
 jsonReader: {
    repeatitems: false,
    root: function (obj) {
       return obj;
    },
 },
 onSelectRow: filterDetail,
});

UPDATE：这是filterDetail函数。它只在另一个网格中过滤

function filterDetail(id) {
  var grid = $("#InventorySummary");
  var search = [];

  do {
     search.push({ id: grid.getCell(id, 'SearchID'), type: grid.getCell(id, 'Type') });
     id = grid.getCell(id, 'parent');
  }
  while (Boolean(id));

  var newLogs = logs.filter(function (x) {
     return search.every(function (s) {
        return x[s.type] === s.id;
     });
  });
  $("#InventoryLogs").jqGrid("clearGridData").jqGrid("setGridParam", { data: newLogs, }).trigger("reloadGrid");
}

在jqgrid内部进行混乱之后，事实证明你需要将json中的parent属性设置为字符串，而不是整数：
