Question

I’m using

getGridParam('selarrrow'); 

to get the rows that are selected,where the method returns me the selected row ids according to their selection,but I want the ids according to their index.Do I have to write a method to sort the ids or is there a inbuilt method which returns me the selected row ids in order of their indexes.

thanks in advance

If you mean the index of the row in the grid then you have to resort the array or id returned by $("#gridId").jqGrid("getGridParam", "selarrrow"). You can use sort() method of Array with your custom sort function. You can just use the fact that ids are the ids of <tr> elements. So the DOM elements of <tr> has native implemented rowIndex property which you can get by $("#"+rowid)[0].rowIndex.

In the simplified form the code could be about the following

var selRowIds = $("#gridId").jqGrid("getGridParam", "selarrrow");

selRowIds.sort(function (id1, id2) {
    // one can use document.getElementById alternatively
    return $("#" + id1)[0].rowIndex - $("#" + id2)[0].rowIndex;
});

or you can use namedItem method instead

var $grid = $("#gridId"),
    selRowIds = $grid.jqGrid("getGridParam", "selarrrow"),
    rows = $grid[0].rows;

selRowIds.sort(function (id1, id2) {
    return rows.namedItem(id1).rowIndex - rows.namedItem(id2).rowIndex;
});

Probably you should include more verification in the code to be sure that the item with id will be found and it has the rowIndex property.
