How to get a jqGrid cell value when editing

This is my solution:

                function getDataLine(grida, rowid){  //vykradeno z inineeditu a vohackovano

                    if(grida.lastIndexOf("#", 0) === 0){
                        grida = $(grida);
                    }else{
                        grida = $("#"+grida);
                    }

                    var nm, tmp={}, tmp2={}, tmp3= {}, editable, fr, cv, ind;

                    ind = grida.jqGrid("getInd",rowid,true);
                    if(ind === false) {return success;}
                    editable = $(ind).attr("editable");
                    if (editable==="1") {
                        var cm;
                        var colModel = grida.jqGrid("getGridParam","colModel") ;
                        $("td",ind).each(function(i) {
                            // cm = $('#mygrid').p.colModel[i];
                            cm = colModel[i];
                            nm = cm.name;
                            if ( nm != 'cb' && nm != 'subgrid' && cm.editable===true && nm != 'rn' && !$(this).hasClass('not-editable-cell')) {
                                switch (cm.edittype) {
                                    case "checkbox":
                                        var cbv = ["Yes","No"];
                                        if(cm.editoptions ) {
                                            cbv = cm.editoptions.value.split(":");
                                        }
                                        tmp[nm]=  $("input",this).is(":checked") ? cbv[0] : cbv[1]; 
                                        break;
                                    case 'text':
                                    case 'password':
                                    case 'textarea':
                                    case "button" :
                                        tmp[nm]=$("input, textarea",this).val();
                                        break;
                                    case 'select':
                                        if(!cm.editoptions.multiple) {
                                            tmp[nm] = $("select option:selected",this).val();
                                            tmp2[nm] = $("select option:selected", this).text();
                                        } else {
                                            var sel = $("select",this), selectedText = [];
                                            tmp[nm] = $(sel).val();
                                            if(tmp[nm]) { tmp[nm]= tmp[nm].join(","); } else { tmp[nm] =""; }
                                            $("select option:selected",this).each(
                                                function(i,selected){
                                                    selectedText[i] = $(selected).text();
                                                }
                                            );
                                            tmp2[nm] = selectedText.join(",");
                                        }
                                        if(cm.formatter && cm.formatter == 'select') { tmp2={}; }
                                        break;
                                }
                            }
                        });
                    }
                    return tmp;
                }

I think that Aidan's answer is by far the best.

$('#yourgrid').jqGrid("editCell", 0, 0, false);

This commits any current edits, giving you access to the real value. I prefer it because:

• You don't have to hard-code any cell references in.
  • It is particularly well suited to using getRowData() to get the entire grid, as it doesn't care which cell you've just been editing.
  • You're not trying to parse some markup generated by jqGrid which may change in future.
  • If the user is saving, then ending the edit session is likely the behaviour they would want anyway.

I needed the original value before the formatter, so this is what I did:

{
    name: 'Slot', title: false, formatter: function (cellValue, options, rowObject) {
        rowObject['SlotID'] = cellValue;  // <--- This saves the original ID
        if (somelogic) {
            return someString;
        } else {
            return someOtherString;
        }
    }
},
{ name: 'SlotID', hidden: true }

Now SlotID contains the original ID. Also, you don't need to have SlotID property on your original model.

try subscribing to afterEditCell event it will receive (rowid, cellname, value, iRow, iCol) where value is your a new value of your cell
