jqGrid pivot获取所有行包括小计数据及原码分析

1.结论：按正常jqGid获取，在中间加入以下代码，即将小计行当成改变为普能行，以便能让'getRowData'方法获取到，第三点会进行原码分析

 //get all page grid data,including group count row
  getJQAllData:function (jqGridId) {
        var o = $("#"+jqGridId);
        //get current page data $("#jqGridList").jqGrid('getRowData');
        var rows=[];
        rows= o.jqGrid('getRowData');
        var rowNum = o.jqGrid('getGridParam', 'rowNum'); //get the record amount of current page data
        var total = o.jqGrid('getGridParam', 'records'); //get the total records of all page
        //reload the all data with no spliting of page,then can get all real data by invoking the function getRowData
        o.jqGrid('setGridParam', { rowNum: total }).trigger('reloadGrid'); 

        //here modify temporaily the attributes of "the group count row" ,so that can get the rows by invoking the function getRowData
        //will restore after below reloadGrid is invoked
        //below three row codes can be executed lonely in IE console
        //if want to understand more please refer to the definition of function getRowData in js/jgGrid/jquery.jqGrid.src.js
        $('tr[id^="jqGridListghead"]').addClass("jqgrow");//add the class to set it as normal row
        $('tr[id^="jqGridListghead"] td').attr("role","gridcell");//add the attributes to set it as normal row
        $('tr[id^="jqGridListghead"] td span').remove();//remove unnecessary <span> in the first <td> of the "the group count row",otherwise the got value from <td> will include excessive "<span....>"
        

        rows = o.jqGrid('getRowData');  //get all grid data,and return {} if emtpy
        o.jqGrid('setGridParam', { rowNum: rowNum }).trigger('reloadGrid'); //reset the original show
        console.log("getJQAllData==>");
        console.log(rows);
        return (rows instanceof Array)?rows:[];
    }

2.获取小计行

3.原码分析：在jquery.jqGrid.src.js第3103行找到方法定义，发现对标题进行了过滤，只需要对相应元素增加属性即可。

getRowData : function( rowid ) {
        var res = {}, resall, getall=false, len, j=0;
        this.each(function(){
            var $t = this,nm,ind;
            if(rowid === undefined) {
                getall = true;
                resall = [];
                len = $t.rows.length;
            } else {
                ind = $($t).jqGrid('getGridRowById', rowid);
                if(!ind) { return res; }
                len = 2;
            }
            while(j<len){
                if(getall) { ind = $t.rows[j]; }
                if( $(ind).hasClass('jqgrow') ) {
                    $('td[role="gridcell"]',ind).each( function(i) {
                        nm = $t.p.colModel[i].name;
                        if ( nm !== 'cb' && nm !== 'subgrid' && nm !== 'rn') {
                            if($t.p.treeGrid===true && nm === $t.p.ExpandColumn) {
                                res[nm] = $.jgrid.htmlDecode($("span:first",this).html());
                            } else {
                                try {
                                    res[nm] = $.unformat.call($t,this,{rowId:ind.id, colModel:$t.p.colModel[i]},i);
                                } catch (e){
                                    res[nm] = $.jgrid.htmlDecode($(this).html());
                                }
                            }
                        }
                    });
                    if(getall) { resall.push(res); res={}; }
                }
                j++;
            }
        });
        return resall || res;
    }
