我有一个定义了状态列的子网格。我想在其navGrid上禁用“添加”按钮，直到子网格的状态列的值为“已完成”。
以下是我正在（不成功）尝试操作的HTML生成片段:(我想我需要使用第一个和最后一个元素）...... ???
<div id="USAttorneyFoldersGrid_43" class="tablediv">
<div id="gbox_USAttorneyFoldersGrid_43_t" class="ui-jqgrid ui-widget ui-widget-content ui-corner-all" dir="ltr" style="width: 826px;">
<div id="lui_USAttorneyFoldersGrid_43_t" class="ui-widget-overlay jqgrid-overlay"></div>
<div id="load_USAttorneyFoldersGrid_43_t" class="loading ui-state-default ui-state-active" style="display: none;">Loading...</div>
<div id="editmodUSAttorneyFoldersGrid_43_t" class="ui-widget ui-widget-content ui-corner-all ui-jqdialog jqmID1" dir="ltr" style="width: 300px; height: auto; z-index: 950; overflow: hidden; top: 294px; left: 136px; display: none;" tabindex="-1" role="dialog" aria-labelledby="edithdUSAttorneyFoldersGrid_43_t" aria-hidden="true">
<div id="gview_USAttorneyFoldersGrid_43_t" class="ui-jqgrid-view" style="width: 826px;">
<div id="rs_mUSAttorneyFoldersGrid_43_t" class="ui-jqgrid-resize-mark"> </div>
<div id="p_USAttorneyFoldersGrid_43_t" class="scroll ui-state-default ui-jqgrid-pager ui-corner-bottom" style="width: 826px;" dir="ltr">
<div id="pg_p_USAttorneyFoldersGrid_43_t" class="ui-pager-control" role="group">
这是我的选择器似乎不起作用：
$('#USAttorneyFoldersGrid_43').navGrid('pg_p_USAttorneyFoldersGrid_43_t', { add: false });
我在这里缺少什么？
