Question

如何获取网格中每一行的ID，甚至跨页面？

getDataIDs和getRowData仅提供当前页面的ID。

谢谢！

Answer 1

只有当您拥有本地网格（datatype:'local'或拥有loadonce:true）时才有可能。在这种情况下，所有页面的所有数据包含ID都已在本地。在这种情况下，您可以使用_index参数，该参数通常与另一个更为已知的参数data一起使用。与

var idToDataIndex = $("#list").jqGrid('getGridParam','_index');

您将获得_index参数。它是一个具有网格所有id的属性的对象。所以你可以用

枚举id

var id;
for (id in idToDataIndex) {
    if (idToDataIndex.hasOwnProperty(id)) {
        // id is the rowid.
        // to get the data you can use
        // mydata[idToDataIndex[id]] where
        // var mydata = $("#list").jqGrid('getGridParam','data');
    }
}

Answer 2

在jqGrid的更高版本中，他们推出了一个更适合这种情况的函数，因为它会考虑可能存在的任何工具栏过滤。 See Oleg's example here.因此，如果您有一个jqGrid（loadonce：true和/或数据类型：local），则以下将返回与当前过滤匹配的所有行ID（显示在当前页面及更高版本中）。

var allIdsWithFiltering = grid.jqGrid('getGridParam', 'lastSelectedData');

这将返回一个普通数组，与原始答案不同，后者返回一个具有必须枚举的属性的对象。

Answer 3

还有另一种在jqgrid上的较旧版本中获取此数据的方法：

gRowNum = grid.jqGrid('getGridParam','rowNum');

grid.setGridParam({rowNum: '9999'});
grid.trigger("reloadGrid");
myList = grid.jqGrid('getDataIDs');

grid.setGridParam({rowNum: gRowNum});
grid.trigger("reloadGrid");

Answer 4

考虑到自IE9以来支持Object.keys，如果您只需要ID ，如今我会使用：

var idToDataIndex = $("#list").jqGrid('getGridParam','_index');
var ids = Object.keys(idToDataIndex);

$(function () {
    "use strict";
    $("#list").jqGrid({
        colModel: [
            { name: "name", label: "Client", width: 53 },
            { name: "invdate", label: "Date", width: 90, align: "center", sorttype: "date",
                formatter: "date", formatoptions: { newformat: "d-M-Y" },
                searchoptions: { sopt: ["eq"] } },
            { name: "amount", label: "Amount", width: 65, template: "number" },
            { name: "tax", label: "Tax", width: 41, template: "number" },
            { name: "total", label: "Total", width: 51, template: "number" },
            { name: "closed", label: "Closed", width: 59, template: "booleanCheckbox", firstsortorder: "desc" },
            { name: "ship_via", label: "Shipped via", width: 87, align: "center",
                formatter: "select",
                formatoptions: { value: "FE:FedEx;TN:TNT;DH:DHL", defaultValue: "DH" },
                stype: "select",
                searchoptions: { value: ":Any;FE:FedEx;TN:TNT;DH:DHL" } }
        ],
        data: [
            { id: "10",  invdate: "2015-10-01", name: "test",   amount: "" },
            { id: "20",  invdate: "2015-09-01", name: "test2",  amount: "300.00", tax: "20.00", closed: false, ship_via: "DH", total: "320.00" },

            { id: "50",  invdate: "2015-10-31", name: "test5",  amount: "300.00", tax: "20.00", closed: false, ship_via: "FE", total: "320.00" },
            { id: "60",  invdate: "2015-09-06", name: "test6",  amount: "400.00", tax: "30.00", closed: false, ship_via: "FE", total: "430.00" },

但是，请同时阅读并推荐Oleg's answer，因为它具有可以执行此操作的条件和重要信息。

jqgrid版本<4.7的警告：

如果您要动态地从网格（delRowData）中删除行，则_index仍将具有已删除的行。您可以通过jqgrid.base.js中的fixing "refreshIndex"来解决此问题（就像4.7中一样）。
