jqGrid modal edit save only changed data and marked edited row?

Question

I use jqGrid 4.9.3-pre - free jqGrid by Oleg. I edit data using the model window "Form Editing". The data get from the server. datatype: "json" with loadonce: false , paging of data don't use I use a standard table. Just call "Form Editing" ondblClickRow.

    ondblClickRow: function(rowid) {
  $(this).jqGrid('setSelection', rowid)
           .jqGrid("editGridRow", rowid, { 
    recreateForm: true,
    width: 1000,
    height: "auto"});
    }

Two questions:

1. Mark the row when has been edited.
2. When you edit the data and press the button Save. How do I send the data that has been modified data to the server?

Answer 1

I find your question interesting and so I created the demo , which demonstrates one of the possible implementation of making edited field of form editing. The results looks like on the picture below

The corresponding code is inside of beforeShowForm callback:

beforeShowForm: function ($form) {
    var $self = $(this),
        myMarker = "<span class='mychanged-item fa fa-lg fa-arrow-circle-o-left' style='display:none;border-radius:6px;background-color:LightGreen;'></span>";
    $form.find(".FormElement").focusout(function () {
        var colName = $(this).attr("name"),
            rowid = $form.find("input[name='" + $self[0].id + "_id" + "']")
                    .val(),
            oldValue = $self.jqGrid("getCell", rowid, colName),
            $myMarker = $(this).closest("td")
                        .next("td")
                        .find("span.mychanged-item");
        if ($(this).val() !== oldValue) {
            $myMarker.css("display", "");     // show
        } else {
            $myMarker.css("display", "none"); // hide
        }
    }).each(function () {
        $(this).closest("td")
            .after("<td style='width:15px'>" + myMarker + "</td>");
    });
}
