Question

我在这里有一些遗留代码，我使用jqGrid来分页XML数据。 XML包含354条记录，一旦页面加载就会显示前20条记录，但是jqGrid不会显示链接以浏览其他记录并对它们进行分页。

我确信jqGrid正在获取完整的XML，它甚至会说Viewing 1 - 20 of 354，但实际上并没有让我分页。

如果我输入分页编号（例如第2页的“2”）并输入它，它会发出HTTP请求（返回200状态）并且什么都不做！

这是分页的JS代码：

$(document).ready(function() {
    erc_id = $('#erc_id').val();

    jQuery("#list4").jqGrid({
        url: "/ercs/" + erc_id + "/exemplares.xml",
        datatype: "xml",
        width: 650,
        pager: "gridPager",
        height: 'auto',
        xmlReader: {
            root: "exemplares",
            row: "exemplar",
            repeatitems: false,
            id: "id"
        },
        colNames: ['Código', 'Referência', 'Num. Controle', 'Dt. Moldagem', 'Traço'],
        colModel: [
            {
            name: 'codigo',
            index: 'codigo',
            width: 60,
            sortable: false},
        {
            name: 'referencia',
            index: 'referencia',
            width: 160,
            sortable: false},
        {
            name: 'numero-controle',
            index: 'numero-controle',
            width: 60,
            sortable: false,
            align: 'center'},
        {
            name: 'data-moldagem',
            index: 'data-moldagem',
            width: 60,
            sortable: false},
        {
            name: 'traco',
            index: 'traco',
            width: 60,
            sortable: false,
            xmlmap: "traco>reference"},
            ],
        viewrecords: true,
        caption: "Exemplares",
        subGrid: true,
        subGridRowExpanded: function(subgrid_id, row_id) {
            var subgrid_table_id = subgrid_id + "_t";
            my_row_id = row_id
            $("#" + subgrid_id).html("<table id='" + subgrid_table_id + "' class='scroll'></table>");
            row_id = row_id.replace("5687", "");
            jQuery("#" + subgrid_table_id).jqGrid({
                url: "/ercs/" + erc_id + "/exemplares/" + row_id + "/cps.xml",

如果您知道可能导致此错误的原因，请告诉我。

我建议在网格定义中添加gridComplete函数，然后您就可以轻松检查控制分页的一些值：

gridComplete: function(){
  var r = $(this).getGridParam('records');
  var p = $(this).getGridParam('page');
  var rec = $(this).getGridParam('reccount');
  var row = $(this).getGridParam('rowNum');
}

以下是他们所有记录的地方：
