如何获取编辑的所有行？

我有以下jqgird,用户可以编辑所有记录的复选框.
单击“保存”按钮时,我需要知道编辑的所有记录是什么,我是jquery和jqgrid的新手.

谁能帮我 ？

这是jqgrid和html使用：

var customerCodesView       = {};
customerCodesView.customerCodesView = function() {

$jq("#customerCodesTable").jqGrid(
        {   
            colNames : ['Cust #','Customer Name','1','2','3','4','5','6','7','8','9','10','11','12','13','-1'],colModel : [{name : 'customerNumber',index : 'baseCustomerNumber',width : 55,align :'center'},{name : 'customerName',index : 'storeName',width : 100,sorttype :'text',{name : 'creditCodesPermissions.1',index : 'codeOne',width : 40,align : "center",editable:true,edittype:'checkBox',editoptions: { value:"True:False"},formatter: "checkBox",formatoptions: {disabled : false}},{name : 'creditCodesPermissions.2',index : 'codeTwo',{name : 'creditCodesPermissions.3',index : 'codeThree',{name : 'creditCodesPermissions.4',index : 'codeFour',{name : 'creditCodesPermissions.5',index : 'codeFive',{name : 'creditCodesPermissions.6',index : 'codeSix',{name : 'creditCodesPermissions.7',index : 'codeSeven',{name : 'creditCodesPermissions.8',index : 'codeEight',{name : 'creditCodesPermissions.9',index : 'codeNine',{name : 'creditCodesPermissions.10',index : 'codeTen',{name : 'creditCodesPermissions.11',index : 'codeEleven',{name : 'creditCodesPermissions.12',index : 'codeTwelve',{name : 'creditCodesPermissions.13',index : 'codeThirteen',{name : 'creditCodesPermissions.-1',index : 'codeMinusOne',formatoptions: {disabled : false}}
                       ],pager : '#customerCodesTablePager',rowNum : 1000,loadOnce:true,sortorder : "desc",viewrecords : true,gridview : true,autowidth : true,multiselect : true,jsonReader : {
                repeatitems : false,root : function(obj) {
                    return obj;
                },page : function(obj) {
                    return 1;
                },total : function(obj) {
                    return 1;
                },records : function(obj) {
                    return obj.length;
                }
            },sortable : true,caption : "Credit Codes"
        });

$jq("form#customerCodesForm").submit(
                function() {
                    var newUrl = resourceURL+"&action=searchCreditCodes&"+ $jq(this).serialize();
                    $jq("#customerCodesTable").jqGrid("setGridParam",{"url" : newUrl,datatype : "json"}).trigger("reloadGrid");
                    return false;
                });

$jq(".submit").button( {
    icons : {
        primary : 'ui-icon-circle-zoomin'
    }
});

$jq("#customerCodesTableSave").click(function() {

    var id = $jq("#customerCodesTable").jqGrid('getGridParam','selarrow');
    alert("save");
    if (id) {
        var rowdata = $jq("#customerCodesTable").jqGrid('getRowData',id);
        var postData = JSON.stringify(rowdata);

        alert("postdata"+postData);
    }
    saveGrid();

});


function saveGrid() {
    alert("saveGrid");
    var saveCollection = [];
    //Collect all rows in editmode,the rows to be saved.
    $.each($jq("#customerCodesTable").getDataIDs(),function (index,id) {
        var row = grid.getInd(id,true);
        if (row !== false) {
            if ($(row).attr('editable') === '1') {
                saveCollection.push(id);
            }
        }
    });
    alert(""+saveCollection.toString() + "length" + saveCollection.length );
}

};

HTML：

var myCheckBoxTemplate = {
    width: 40,align: "center",editable: true,edittype: 'checkBox',editoptions: { value: "True:False"},formatoptions: {disabled : false}
};

{name: 'creditCodesPermissions1',index: 'codeOne',template: myCheckBoxTemplate}
