how to send jqGrid data in json format to server? DO I have to use any external library or script to achieve that?

Thanks!

update1: extra licensePlateNumber should not be there

Your approach from your other question is OK, but jQuery.ajax has problems to serialize arrays. The most reliable and standard way (see here and here as examples) which I see is to serialize all jqGrid data to JSON (for example with respect of JSON.stringify function:

$("#sendButton").click(function(){
    var gridData = jQuery("#list").getRowData();
    var postData = JSON.stringify(gridData);
    alert("JSON serialized jqGrid data:\n" + postData);
    $.ajax({
        type: "POST",
        url: "/cpsb/internalOrderList.do",
        data : {
            jgGridData: postData,
            customData: "bla bla"
        },
        dataType:"json",
        contentType: "application/json; charset=utf-8",
        success: function(response, textStatus, xhr) {
            alert("success");
        },
        error: function(xhr, textStatus, errorThrown) {
            alert("error");
        }
    });
});

the names of parameters jgGridData, customData and so on, you can choose whatever you like.
