jqGrid中获取subGrid的标题栏对象

jqGrid中subGrid的使用方法也很简单，设置subGrid:true,并且配置subGridRowExpanded，该属性是一个函数，在这个函数实现对subGrid的绘制，

思路也很简单，就是在当前的格子中插入table和div，然后在是通常的jqGrid的写法。大多数参数的配置和jqGrid的常规配置一致。

在要获取标题栏的时候，通过打印html(),发现，jqGrid构造的表格还是很复杂的。它的标题栏不是想象中的首行，而是另外一个独立的table，因此，要获得它也蛮复杂的，通过一系列parent()方法。下面是一段例子

subGridRowExpanded: function(subgrid_id, row_id) {

// we pass two parameters

// subgrid_id is a id of the div tag created within a table

// the row_id is the id of the row

// If we want to pass additional parameters to the url we can use

// the method getRowData(row_id) - which returns associative array in type name-value

// here we can easy construct the following

var subgrid_table_id,subgrid_pager_id;

subgrid_table_id = subgrid_id+"_t";

subgrid_pager_id = subgrid_id+"_div";

jQuery("#"+subgrid_id).append("<table id='"+subgrid_table_id+"' class='scroll'></table>");

jQuery("#"+subgrid_id).append("<div id='"+subgrid_pager_id+"' class='scroll'></div>");

jQuery("#"+subgrid_table_id).jqGrid({

url:"./AjaxHandler/jqGrid_Jsondata_Content.ashx?id="+row_id,

datatype: "json",

jsonReader: {

root: "rows",

page: "page",

total: "total",

records: "records",

repeatitems: false,

id: "rowid"

colNames: ["内容", "作者", "时间"],

colModel: [

{ name: "content", index: "content", 550, sorttype: "string",sortable:false },

{ name: "author", index: "author", 80, sorttype: "string", formatter: "string",sortable:false },

{ name: "datetime", index: "datetime", 80, sorttype: "string", formatter: "string",sortable:false}

rowNum: 15,

height: "100%",

viewrecords: true,

pager:"#"+subgrid_pager_id,

loadComplete:function(){

//隐藏第一行标题栏

var p= $("#"+subgrid_table_id).parent().parent().parent()

p=$(p).find("table").first().hide();

}

});

}

表格html如下：

TABLE

style=" 725px" class=ui-jqgrid-htable role=grid aria-labelledby=gbox_listdata_jqtr88_t border=0 cellSpacing=0 cellPadding=0>

<THEAD>

<DIV id=jqgh_listdata_jqtr88_t_datetime class="ui-th-div-ie ui-jqgrid-sortable">时间<SPAN style="DISPLAY: none" class=s-ico><SPAN class="ui-grid-ico-sort ui-icon-asc ui-state-disabled ui-icon ui-icon-triangle-1-n ui-sort-ltr" sort="asc"></SPAN><SPAN class="ui-grid-ico-sort ui-icon-desc ui-state-disabled ui-icon ui-icon-triangle-1-s ui-sort-ltr" sort="desc"></SPAN></SPAN></DIV></TH></TR></THEAD></
