Add/edit/delete a row in free jqGrid

I am using free jqGrid 4.12.1. I want to add, edit and delete rows in the grid and wish to make server side calls for each operation.
I have added editurl and 'actions' formatter as below,
{
name: "actions",
width: 100,
formatter: "actions",
formatoptions: {
keys: true,
editOptions: {},
addOptions: {},
delOptions: {}
}
}
I am adding 'inlineNav' as below,
$("#itemList").jqGrid('inlineNav',"#itemListPager",
{
edit: true,
add: true,
del: true,
search: true,
searchtext: "Search",
addtext: "Add",
edittext: "Edit",
deltext: "Delete"
},
{
closeOnEscape: true, //Closes the popup on pressing escape key
reloadAfterSubmit: true,
drag: true,
url: "${pageContext.request.contextPath}/billing/saveItem",
errorfunc: function (rowId, resp) {
alert(resp);
},
afterSubmit: function (response, postdata) {
if (response.responseText == "") {
$(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid'); //Reloads the grid after edit
return [true, '']
}
else {
$(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid'); //Reloads the grid after edit
return [false, response.responseText]//Captures and displays the response text on th Edit window
}
},
editData: {
EmpId: function () {
var sel_id = $('#itemList').jqGrid('getGridParam', 'selrow');
var value = $('#itemList').jqGrid('getCell', sel_id, '_id');
return value;
}
}
},
{
closeAfterAdd: true, //Closes the add window after add
url: "${pageContext.request.contextPath}/billing/saveItem",
afterSubmit: function (response, postdata) {
if (response.responseText == "") {
$(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid')//Reloads the grid after Add
return [true, '']
}
else {
$(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid')//Reloads the grid after Add
return [false, response.responseText]
}
}
},
{ //DELETE
closeOnEscape: true,
closeAfterDelete: true,
reloadAfterSubmit: true,
url: "${pageContext.request.contextPath}/billing/saveItem",
drag: true,
afterSubmit: function (response, postdata) {
if (response.responseText == "") {
$("#itemList").trigger("reloadGrid", [{ current: true}]);
return [false, response.responseText]
}
else {
$(this).jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid');
return [true, response.responseText]
}
},
delData: {
EmpId: function () {
var sel_id = $('#itemList').jqGrid('getGridParam', 'selrow');
var value = $('#itemList').jqGrid('getCell', sel_id, '_id');
return value;
}
}
},
{//SEARCH
closeOnEscape: true
}
);
The 'inlineNav' added above has no effect because no server side call is made on adding a new row or deleting existing row. The server side call is made only in case of edit, and that call too does not happen through 'inlineNav' code above. Because even if i remove 'inlineNav' code the server side call is still made to the 'editurl'.
So how can i make server side calls on adding/editing/deleting rows and also pass parameters to these calls. I will really appreciate if someone can point me to a working example somewhere. Thanks
UPDATE:-
I have removed 'actions' formatter and modified code to look as below,
<script type="text/javascript">
var dataGrid = $('#itemList');
var firstClick = true;
$(document).ready(function () {
$('#action').click(function () {
if (!firstClick) {
$("#itemList").setGridParam({datatype:'json'}).trigger("reloadGrid");
}
firstClick = false;
$("#itemList").jqGrid({

$("#itemList").jqGrid('filterToolbar', {autoSearch: true, stringResult: true, searchOnEnter: false, defaultSearch: 'cn'});
$("#itemList").jqGrid('gridResize', { minWidth: 450, minHeight: 150 });
var saveparameters = {

"extraparam" : {},

};
var editparameters = {

</script>
The sample json dada is as,
[
{"itemDetailId":1,"itemId":1,"itemType":"Medicine","itemCode":"Aler-Dryl","itemDesc":"Aler-Dryl","batchNumber":"batch1","expiryDate":"18/02/2017","unit":"tablet","subUnit":"tablet","availableQuantity":120.0,"quantityPerUnit":60.0,"price":122.0},
{"itemDetailId":2,"itemId":2,"itemType":"Medicine","itemCode":"Benadryl","itemDesc":"Benadryl","batchNumber":"batch1","expiryDate":"18/02/2017","unit":"ml","subUnit":"ml","availableQuantity":60.0,"quantityPerUnit":120.0,"price":90.0}
]
Now the url specified in editparameters and saveparameters is getting invoked on editing and adding a row respectively.
Please suggest if above approach is a good one. Also how can we set a request header before edit or save data is posted to server. And i can not find anything like deleteparameters similar to editparameters and saveparameters so that i can use delete specific parameters.
UPDATE 2:-
I could successfully set a request header before server side code is invoked on add/edit row using following code,
$.ajaxSetup({
beforeSend: function (jqXHR, settings) {
jqXHR.setRequestHeader("X-CSRF-TOKEN", $("input[name='_csrf']").val());
}});
UPDATE 3:-
Cleaned up code as per Oleg's suggestions as below. But in the strict mode i am getting JS error now - "Uncaught ReferenceError: saveparameters is not defined"

});
});
</script>

You should examine the options of inlineNav to find out that you use absolutely wrong options:
jQuery("#grid_id").jqGrid('inlineNav', pagerid, parameters);
where parameters have the form
{
edit: true,
editicon: "ui-icon-pencil",
add: true,
addicon: "ui-icon-plus",
save: true,
saveicon: "ui-icon-disk",
cancel: true,
cancelicon: "ui-icon-cancel",
addParams: {useFormatter : false},
editParams: {}
}
You use the options of another method navGrid
jQuery("#grid_id").jqGrid('navGrid', '#gridpager', {parameters},
prmEdit, prmAdd, prmDel, prmSearch, prmView);
which allows to use form editing.
You wrote that you want to use both formater: "actions" andinlineNav. Thus you would have to provide some options of inline editing twice. I would recommend you to read [the wiki article](https://github.com/free-jqgrid/jqGrid/wiki/New-style-of-usage-options-of-internal-methods). It describes the problems with the usage of form editing usingformatter: "actions"andnavGridtogether. The usage of inline editing have very close problems. You will have to provideaddParamsandeditParamsproperties ofinlineNavand the corresponding options offormatter: "actions"` (see here). To make the code more readable and simple free jqGrid provides another form of editing options.
You can specify all inline editing options inside of inlineEditing option of jqGrid, additional specific options of inlineNav method (if required) in navOptions or in inlineNavOptions, the options of Delete operation in formDeleting and so on. Moreover reloadGrid have the option fromServer: true to restore the original value of datatype ("json", "jsonp", "xml", ...) which you used. You can use reloadGridOptions: { fromServer: true } option of form editing or formDeleting to force reloading from the server.
Moreover your existing code contains many very suspected parts with _id and EmpId. I would strictly recommend you to include the example of format of input JSON data which you use to fill the grid. If you want to use EmpId as the name of rowid why you use _id instead? The code fragment like
EmpId: function () {
var sel_id = $('#itemList').jqGrid('getGridParam', 'selrow');
var value = $('#itemList').jqGrid('getCell', sel_id, '_id');
return value;
}
shows that the current rowid seems be wrong and _id column contains correct information which you need as rowid under the name EmpId.
You can for example use prmNames: { id: "EmpId"} and to add key: true to the column _id. The property key: true in the column _id will inform jqGrid to use the value from the column _id as the rowid and prmNames: { id: "EmpId"} will rename default id property used in Edit and Delete to EmpId. Thus jqGrid will automatically send EmpId parameter with the value from _id column during Delete and Edit operations to the server.
Probably you can remove unneeded column _id from the grid too (at least if you hold the column hidden), but I need to see input data of jqGrid to say you exact options of jqGrid which you can use.
I'm sure that you can essentially reduce your existing code and make it more readable using free jqGrid options, but you have to review your existing code carefully. I suggest you to start with the usage of correct rowid and elimination of all hidden columns which you use. Free jqGrid provides additionalProperties feature which structure is very close to the structure of colModel, but the corresponding properties of input data will be saved in the local data only and not placed in DOM of the table. I can explain all more clear if you would post your existing colModel, jsonReader and example of JSON response returned from the server (1-2 rows of data with dummy data would be enough).

jQGrid - "jpg1" instead of proper id number

I'm loading local file (I'm parsing csv file into json and then transfer the array to jqGrid). Table generated through jqGrid should allow user to modify, add and delete the data in the grid. Everything seemed to work perfectly until I wanted to add a row to my grid. One of the columns had a parameter key = true which is my id for the rows. When I try to add new row, the grid changes my id into jpg1. The others columns are fine. Below is the code I'm using:
$("#jqGrid").jqGrid({
datatype: "local",
data: myData,
editurl: "clientArray",
colModel: [
{
label: 'Kod',
name: 'Kod',
width: 60,
editable: true,
key: true,
sorttype: 'number'
},
{
label: 'Firma',
name: 'Firma',
width: 120,
editoptions:
{
size: 40,
sopt:['cn']
},
editable: true,
sorttype: 'string'
},
{
label: 'Adres',
name: 'Adres',
width: 80,
editoptions: {size: 40},
editable: true
},
{
label: 'Miasto',
name: 'Miasto',
width: 80,
editoptions:
{
size: 40,
sopt:['cn']
},
editable: true
}
],
height: 'auto',
autowidth: true,
shrinkToFit: false,
forceFit: false,
autoencode: true,
viewrecords: true,
caption: "Title",
pager: "#jqGridPager",
sortable: true,
ignoreCase: true,
sortname: 'Kod',
sortorder: 'asc',
rowNum: 5,
rowList: [5, 10, 20, "10000:All"],
ondblClickRow: function(rowid) {
$("#jqGrid").jqGrid('editGridRow', rowid,
{
editCaption: "The Edit Dialog",
zIndex:100,
recreateForm: true,
closeAfterEdit: true,
width: 900,
errorTextFormat: function (data) {
return 'Error: ' + data.responseText
}
});
}
});
$('#jqGrid').jqGrid('navGrid',"#jqGridPager",
{ edit: true, add: true, del: true, search: false, refresh: true, view: true, cloneToTop: true},
// options for the Edit Dialog
{
editCaption: "The Edit Dialog",
zIndex:100,
recreateForm: true,
closeAfterEdit: true,
reloadAfterSubmit: true,
width: 900,
errorTextFormat: function (data) {
return 'Error: ' + data.responseText
}
},
// options for the Add Dialog
{
width: 900,
zIndex:100,

}
},
// options for the Delete Dialog
delSettings,
// options for the Search Dialog
{
zIndex:100
},
// options for the View Dialog
{
width: '100%'
});
I'm attaching a screenshot that shows a problem:
Photo
The data I use is a file parsed into JSON array via Papaparse.js plugin.
EDIT:
I've added the test data if somebody would like to test the code.
var myData = [];
myData.push(
{
Kod: 1.1,
Firma: 'Hutchinson',
Adres: '5th Avenue',
Miasto: 'Wroclaw'
},
{
Kod: 2.1,
Firma: 'BMW',
Adres: '6th Avenue',
Miasto: 'Warsaw'
});
I will be grateful for any help.

If you need the grid only for local editing, you can consider just remove key: true property to solve the problem. It's the way, which I would recommend you. You can include id property in the input data which will be used as value of rowid (id of <tr> elements).
Alternatively you can change the block "options for the Add Dialog" to the following
// options for the Add Dialog
{
width: 900,
zIndex:100,
closeAfterAdd: true,
recreateForm: true,
reloadAfterSubmit: true,
onclickSubmit: function (options, postdata, frmoper) {
// save Kod in some other parameter
return {myKod: postdata.Kod};
},
afterSubmit: function (jqXHR,postdata, frmoper) {
// restore the correct value
postdata.Kod = postdata.myKod;
// inform jqGrid that it was not an error
return [true];
}
},
You still don't would be able to change the id of the row in the way.
By the way you wrote that you use jqGrid 4.7.1. I want remind you that jqGrid 4.7.0 is the last version which is free. It's the reason why I started free jqGrid project which still free. You can get it here (see readme and wiki).
The demo shows an example of the above code fixes using free jqGrid 4.8.

Jqgrid search option for local datatype not working

I want to add search option for my jqgrid table,
$('#jqgrid').jqGrid({
datatype: 'local',
data: mydata,
caption: 'Titlepage Parameters',
gridview: true,
height: 'auto',
colNames: ['title', 'color', 'fontsize'],
colModel: [
{name: 'config.titlepage.title' },
{name: 'config.titlepage.color' },
{name: 'config.titlepage.fontsize' },
],
pager: '#pageGrid'
localReader: {
id: "_id.$oid"
}
});
$('#jqgrid').jqGrid('navGrid', "#pageGrid",
{ search: true, edit: false, add: false, del: false, refresh: false }, {}, {},
{ recreateFilter: true, overlay: true, multipleSearch: true, multipleGroup: true});
I'm getting the search option but when I enter the search string and click on Filter button, search is happening.
Please help me here, do I need add any library files to perform for this search filter?

I'm not sure which problem with searching you have. The only clear error is: you skip one {} in the list of navGrid. You current option of navGrid set delete options as searching options. Correct option will be
$('#jqgrid').jqGrid('navGrid', "#pageGrid",
{ search: true, edit: false, add: false, del: false, refresh: false }, {}, {}, {},
{ recreateFilter: true, overlay: true, multipleSearch: true, multipleGroup: true});
Additionally you can consider to add ignoreCase: true option to the grid to make searching case insensitive. The demo seems to work correctly.
Another option which you can use to read the same data: to use datatype: 'jsonstring'. In the case you can use jsonmap and choose more readable name property. In the case the internal data of grid will contains only the data which you need. The demo demonstrate this approach. It uses the following code
var mydata = [
{
"_id": {"$oid": "50a3f962b7718da1a3090fa9"},
"config": { "titlepage": { "title": "My First Title", "color": true,
"fontsize": "42/44" } } }
];
$('#jqgrid').jqGrid({
datatype: 'jsonstring',
datastr: mydata,
caption: 'Titlepage Parameters',
gridview: true,
height: 'auto',
colModel: [
{name: 'title', jsonmap: "config.titlepage.title" },
{name: 'color', jsonmap: "config.titlepage.color" },
{name: 'fontsize', jsonmap: "config.titlepage.fontsize" },
],
pager: '#pageGrid',
jsonReader: {
repeatitems: false,
id: "_id.$oid"
}
});
$('#jqgrid').jqGrid('navGrid', "#pageGrid",
{ search: true, edit: false, add: false, del: false, refresh: false }, {}, {}, {},
{ recreateFilter: true, overlay: true, multipleSearch: true, multipleGroup: true});
In any way I don't see any problem with searching in both demos.

Javascript variable into postdata of jqGrid

Right now I have this postData: { search: function() { return $("#search").val(); },},
I then have jQuery function above the jqGrid function that performs some logic and produces a string variable. Right now I am just taking that variable and setting the value of the search element like this:
$("#startSearch").click(function() {
$("#search").val(searchVal);
$("#grid").trigger("reloadGrid");
});
This works but I was hopping to do this differently. I want to just pass the seachVal variable that my jQuery function produces right into the postdata.
I tried it like this but its not working postData: { search: function() { return searchVal; },},
I'm getting an error that says searchVal is not defined. I made sure that the searchVal variable is global but it is still not working.
Is this possible or am I just looking at this wrong?
Any help would be great.
Thanks
UPDATE:
Here is a stripped down version of the page:
<fieldset>
<input type='text' id='search' />
<button type='button' id='startSearch'>Search</button>
</fieldset>
<script type="text/javascript">
$(function(){
$("#startSearch").click(function() {
serchVal = 'transID > "5"';
$("#search").val(serchVal);
$("#grid").trigger("reloadGrid");
});
$("#list").jqGrid({
url:'data.cfc?method=gridData',
datatype: 'json',
mtype: 'POST',
jsonReader : {
root: "rows",
page: "currentpage",
total: "totalpages",
records: "totalrecords",
repeatitems: false,
id: "0",
},
postData: { search: function() { return $("#search").val(); },},
colModel :[
{name:'transid', label:'Trans ID', width:60},
{name:'companyname', label:'Company Name', width:245},
{name:'companycode', label:'Company Code', width:245},
{name:'datasource', label:'Datasource', width:245}
],
pager: '#pager',
rowList:[10,50,100],
rowNum:'10',
height:221,
sortname: 'transid',
sortorder: 'asc',
viewrecords: true,
gridview: true,
caption: 'Get Trans',
altRows: false,
autowidth: true,
forceFit: true,
rownumbers: true,
scroll: false,
sortable: true
});
$("#list").jqGrid('navGrid','#pager',{edit:false,add:false,del:false,search:false,view:true});
});
</script>
<table id="grid"></table>
<div id="pager"></div>

I suppose the problem exist just because you didn't declared the variable serchVal (you means probably searchVal). You can try to modify the code to the following
$(function () {
var searchVal = '';
$("#startSearch").click(function () {
searchVal = 'transID > "5"';
$("#grid").trigger("reloadGrid");
});
$("#list").jqGrid({
url: 'data.cfc?method=gridData',
datatype: 'json',
mtype: 'POST',
jsonReader : {
page: "currentpage",
total: "totalpages",
records: "totalrecords",
repeatitems: false,
id: "0"
},
postData: { search: function () { return searchVal; }},
colModel: [
{name: 'transid', label: 'Trans ID', width: 60},
{name: 'companyname', label: 'Company Name', width: 245},
{name: 'companycode', label: 'Company Code', width: 245},
{name: 'datasource', label: 'Datasource', width: 245}
],
pager: '#pager',
rowList: [10, 50, 100],
rowNum: 10,
height: 221,
sortname: 'transid',
viewrecords: true,
gridview: true,
caption: 'Get Trans',
autowidth: true,
rownumbers: true,
sortable: true
}).jqGrid('navGrid', '#pager',
{edit: false, add: false, del: false, search: false, view: true});
});
After that you can remove <input type='text' id='search' />.

Why don't you just wrap your logic in a function
function SomeLogic() {
return("some logic here!");
}
which is going to be called like this:
postData: { search: function() { return SomeLogic() } },
so you just have to reload the grid
$("#startSearch").click(function() {
$("#grid").trigger("reloadGrid");
});
obviously your function SomeLogic can just return searchVal
function SomeLogic() {

Passing dynamic params to delete url method in JQGrid

I am using a JQGrid witha json service to list all the database users membership information, so the url of the grid points to my json service and method. Everything is working fine so far, I can add and edit the users and amend data and it saves fine. However the delete of a DB user is another story as the Membership.DeleteUser takes the username as its parameter. The JQGrid only seems to pass editable params back when in add or edit mode. But when you're trying to delete it doesn't seem to allow any params to be returned which I find very odd. I have only just started using JQGrids so I could just be being thick :-). Please can anyone tell me how to accomplish this? I have the username as a column in the JQGrid itself. I have tried various things to date:
url: 'misc/myservice.svc/AddEditDeleteGridRow?UserName=' + $('#MyGridTbl').getCell('selrow', 'UserName')
in the delete section of the navGrid. I have also tried setting the URL in the select row event too but I found it required a reload to insert it into the grid and when this happens the selected row is lost and so defeats the object. I just need to be able to access/get the username inside the json service in order to pass it to Membership.DeleteUser. I have been searching the internet and can't seem to find anything.
Here is the JQGrid I am using. There json service basically just has the GetData which returns JQGridJSONData (json object dataset) and AddEditDeleteGridRow methods in it, both are public. All the column data is being sent to the json service for the add and edit but nothing is being sent for the delete operation.
Just to clarify I need the UserName on the server side in the json service.
$('#MyGrid').jqGrid({
url: 'Misc/MyjsonService.svc/GetData',
editurl: 'Misc/MyjsonService.svc/AddEditDeleteGridRow',
datatype: 'json',
colNames: ['UserId', 'UserName', 'Email Address', 'Password Last Changed', 'Locked'],
colModel: [

],

},

if (Id && Id !== this.DBUserId) {
this.DBUserSelect(Id);
}
},
loadComplete: function() {
if (this.DBUserId)
this.DBUserSelect(this.DBUserId, true);
},
gridComplete: function() {
var grid = $('#MyGrid');
var body = $('#AvailableDBUsersArea');
if ((grid) && (body)) {
grid.setGridWidth(body.width() - 10);
//keep the grid at 100% width of it's parent container
body.bind('resize', function() {
var grid = $('#MyGrid');
var body = $('#AvailableDBUsersArea');
if ((grid) && (body)) {
grid.setGridWidth(body.width() - 2);
}
});
}
}
}).navGrid('#MyGridPager',
{ add: true, edit: true, del: true, refresh: false, search: false }, //general options

There are some ways to add additional parameters to the Delete URL. It would be helpful to have the definition of the jqGrid, especially colModel.
If you have a hidden column for example use can use
hidden: true, editable: true, editrules: { edithidden: false }, hidedlg: true
parameters. Then the hidden column would be not seen in the edit dialog, but the value of the column will be send.
Another way can you choose if you need modify URL befor sending Delete request. You can define parameter of navGrid (see prmDel paremeter on http://www.trirand.com/jqgridwiki/doku.php?id=wiki:navigator#how_to_use) which can be like following
{ onclickSubmit: function(rp_ge, postdata) {
rp_ge.url = 'misc/myservice.svc/AddEditDeleteGridRow?UserName=' +
$('#MyGridTbl').getCell (postdata, 'UserName');
}
}
