JQgrid - Get Row Number instead of ID

I am creating a JQGrid from a database table that does not contain a single field primary key. Therefore, the field i am supplying as id is not unique and the same one exists in several rows.

Because of this, when passing a reference to the data with ondblClickRow to a function external to the grid i need to use the rownumber and not the id.

To test, I'm using ondblClickRow: function(id){alert($("#grid1").getInd('rowid'));}, , and i should be getting and alert with the row number, except that it isn't working.

I've been over the documentation and can't understand what i am doing wrong...

Any help would be greatly app开发者_如何学Creciated!

Thanks in advance, Mario.

Bellow is my full grid:

jQuery(document).ready(function(){
var mygrid = jQuery("#grid1").jqGrid({
    datatype: 'xmlstring',
    datastr : grid1RsXML,
    width: 1024,
    height: 500,
    colNames:['DEVICE_ID','JOB_SIZE_IN_BYTES', 'USER_NAME','HOST_NAME','DAY_OF_WEEK','JOB_ID'],
    colModel:[ 
                {name:'DEVICE_ID',index:'DEVICE_ID', width:55, sortable:true},
                {name:'JOB_SIZE_IN_BYTES',index:'JOB_SIZE_IN_BYTES', width:40, sortable:true},
                {name:'USER_NAME',index:'USER_NAME', width:60, sortable:true},
                {name:'HOST_NAME',index:'HOST_NAME', width:50,align:"right", sortable:true},
                {name:'DAY_OF_WEEK',index:'DAY_OF_WEEK', width:10, sortable:true},
                {name:'JOB_ID',index:'JOB_ID', width:30, sortable:true}

             ],
    rowNum:1000,
    autowidth: true, 
    //rowList:[10,20,30],
    rowList:[1],
    pager: '#grid1Pager',
    sortname: 'DEVICE_ID',
    viewrecords: true,
    rownumbers: true,
    sortorder: "desc",
    sortable: true,
    gridview : true,
    xmlReader: { root : "recordset", row: "record", repeatitems: false, id: "DEVICE_ID" },
    caption:"All Jobs - Double Click for detailed history",
    ondblClickRow: function(id){alert($("#grid1").getInd('rowid'));}, 
    toolbar: [true,"top"],
    url: grid1RsXML
});

I think you can use the getInd() method, like this:

var sel_id = $grid.getGridParam('selrow');
var index = $grid1.jqGrid('getInd',sel_id); // counting from 1

What you're looking for is already passed to the event, you just need to include more of the available parameters in your function declaration:

ondblClickRow: function(id, iRow, iCol, e) {
    alert(iRow);
},

The answer of your main question gives you great_llama, but it seams to me, that you a little misunderstand id as a XML input used by jqGrid. Default xmlReader has id: "[id]". So you just remove id: "DEVICE_ID" from the definition of xmlReader and place id attribute in your data:

var grid1RsXML = "<?xml version='1.0' encoding='utf-8'?>"+
  "<recordset>"+
      "<rows>"+
          "<record id='1'>"+
              "<DEVICE_ID>data1</DEVICE_ID>"+
              "<JOB_SIZE_IN_BYTES>data2</JOB_SIZE_IN_BYTES>"+
              "<USER_NAME>data3</USER_NAME>"+
              "<HOST_NAME>data4</HOST_NAME>"+
              "<DAY_OF_WEEK>data5</DAY_OF_WEEK>"+
              "<JOB_ID>data6</JOB_ID>"+
          "</record>"+
          "<record id='2'>"+
              "<DEVICE_ID>data1</DEVICE_ID>"+
              "<JOB_SIZE_IN_BYTES>data2</JOB_SIZE_IN_BYTES>"+
              "<USER_NAME>data3</USER_NAME>"+
              "<HOST_NAME>data4</HOST_NAME>"+
              "<DAY_OF_WEEK>data5</DAY_OF_WEEK>"+
              "<JOB_ID>data6</JOB_ID>"+
          "</record>"+
          "<record id='3'>"+
              "<DEVICE_ID>data1</DEVICE_ID>"+
              "<JOB_SIZE_IN_BYTES>data2</JOB_SIZE_IN_BYTES>"+
              "<USER_NAME>data3</USER_NAME>"+
              "<HOST_NAME>data4</HOST_NAME>"+
              "<DAY_OF_WEEK>data5</DAY_OF_WEEK>"+
              "<JOB_ID>data6</JOB_ID>"+
          "</record>"+
      "</rows>"+
  "</recordset>";

So your main data which send your server could have double rows, but if you just add id attribute which can be a row counter you can solve your problem. The value of id attribute must not be a number, you can use any string instead. If the nature of your data allow this, you can produce an unique id as a string composed from your other data.

Recently I had same requirement, i.e to access the row data by row number rather than the row id. I don't have any row id. Below code works for me. NOTE: The row count starts from 1.

var rowNum=$("#grid1").getGridParam("selarrrow"); $("#grid1").getRowData(rowNum);

---

I make it like this:

ondblClickRow:function(rowid,iRow,iCol,e){var curPage =$("#gridTable").getGridParam("page");//current page var pageSize = $("#gridTable").getGridParam("rowNum");//records per pagevar count = parseInt((curPage-1)*pageSize) + parseInt(rowid);}
