jqGrid postData and filtering - javascript

I have been struggling with this all day. My requirement is very simple: I'm using single field searching. I want to save the state of the grid (using postData and a cookie) when I leave the page and restore it when I come back. I'm able to save the postData to a cookie, but can't figure out how to restore the grid state again.
$(document).ready(documentReady);
function documentReady()
{
$("#grid_clients").jqGrid({
datatype: "local",
height: 200,
width: 832,
shrinkToFit: true,
caption:"Clients",
colNames :["","Id","Name","Description","Active<br />Studies"],
colModel :[
{name:"edit", index:"edit", width:20, align:"center", sortable:false, search: false},
{name:"id", index:"id", width:40, align:"right", sorttype:'int'},
{name:"name", index:"name", width:200},
{name:"description", index:"description", width:200},
{name:"studycount", index:"studycount", width:50, align:"right", sorttype:'int'}
],
pager:"pager_clients",
scroll: 1,
viewrecords:true,
sortable:true,
sortname: "name",
autowidth: true,
pgbuttons: false,
loadonce: true,
gridview: true
});
$("#grid_clients").jqGrid("navGrid", "#pager_clients",{add:false, edit:false, del:false});
$('#grid_clients').jqGrid('setGridParam', {datatype: 'xml'});
var gridUrl = 'getgridxmlclients.php';
$('#grid_clients').jqGrid('setGridParam', {url: gridUrl});
// If the cookie exists, set the postData and search parameters.
if ($.cookies.get('gridPostData'))
{
alert(dump($.cookies.get('gridPostData')));
$('#grid_clients').jqGrid('setGridParam', {search: true, 'postData': $.cookies.get('gridPostData')});
}
$('#grid_clients').trigger('reloadGrid', [{page:1}]);
}
The alert for the cookie when coming back to the page looks like this:
'_search' => "true"
'nd' => "1313100751399"
'rows' => "20"
'page' => "1"
'sidx' => "id"
'sord' => "asc"
'searchField' => "studycount"
'searchString' => "1"
'searchOper' => "eq"
'filters' => ""
The interesting thing is that the parameters seem to have taken, because if I just click on a header to sort the grid, the filter takes affect then. I'm missing the method of forcing the filtering when reloading.

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,

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
{

}
},
// 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.

Alter the data before displaying it in the grid

I have a jqGrid that is filled by a JSON request, the thing is that the request back to the server in base64 encoded data and I need to decode the data before assign it to the grid.
Basically I need something like this:
$( "#grid" ).jqGrid( {
datatype: "json",
colNames: ["id", "Num", "Name", "Code"],
colModel: [
{ name: "id", index: "id", width: 30, sortable: true, resizable: false },
{ name: "num", index: "num", width: 150, sortable: true, resizable: false },
{ name: "name", index: "name", width: 250, sortable: true, resizable: false },
{ name: "code", index: "code", width: 150, sortable: true, resizable: false },
],
multiselect: true,
width: "760",
height: "100%",
heightMetric: "%",
shrinkToFit: false,
rowNum: 20,
rowList: [20,30,60],
pager: "#pager",
sortname: "id",
viewrecords: true,
sortorder: "asc",
headertitles : true,
caption: "Loading...",
beforeProcessing: function(data){
data = decompress(data); // Like this
}
})
The callback function beforeProcessing is the correct place where you can implement all what you need. The exact implementation depends on the format of the data returned by the server. If one uses datatype: "json" then the data returned from the server are typically an object which is serializes as JSON string. jqGrid uses internally jQuery.ajax which automatically decode the JSON string and convert it back to object. So the input data parameter of beforeProcessing callback is the object returned from the server. If you don't use any additional jsonReader option of jqGrid then jqGrid wait the input data in the standard format described here. So you need just fill the expected properties of data object (rows, page, total and records) based on the input data returned from the server. You don't posted any example of the data returned from the server, so I could give you no more detailed examples.

jqGrid not showing rows, only shows total number of rows

I'm having a problem that I can't sort it out.
Please take a look at this image first
As you can see, I have been able to request the JSON data from server. The pager shows that there were 4 records. But the records didn't shows in the table.
This is my javascript code
jQuery("#pickFlex66").jqGrid({
url: root + '<?=$mod?>' + '/listpicker',
datatype: "json",
altRows: true,
mtype: 'POST',
colNames:['Code','Company Name'],
colModel:[
{name:'company_code',index:'company_code', width:100},
{name:'company_name',index:'company_name', width:100}
],
rowNum:10,
width: 540,
height: 310,
rowList:[10,20,30],
pager: '#pagerFlex66',
sortname: 'company_code',
shrinkToFit: false,
viewrecords: true,
sortorder: "desc",
caption:"<?=lang("users_title")?>",
onSelectRow: function(id){
}
});
jQuery("#pickFlex66").jqGrid('navGrid','#pagerFlex66',{edit:false,add:false,del:false,search:false});
And here is my JSON data
{
"page": "1",
"total": 0,
"records": "4",
"rows": [{"id":"5","cell":["55-123","123"]},{"id":"3","cell":["123","IBM"]},{"id":"2","cell":["00000","BDO"]},{"id":"1","cell":["000-00","IT GROUP Inc "]}]
}
Is there a mistake in my javascript? Or maybe in my JSON data?
I agree with Briguy37 that the value "total": 0 is strange and of cause incorrect. Nevertheless jqGrid should do display all data.
I suppose that you have the problem in the part of your code which you not posted here. How you can see from the demo the code which you posted can do read and display the JSON data.
Here's a couple issues...haven't figured out why your results aren't getting populated yet, though:
Total in your returned JSON should be the number of pages. Because it is set to 0, that is why it is displaying 0. Also, you'll probably want to return rowCount as 10 in case you change the number of results per page.
You are missing a json reader, I had the exact same problem.
$("#list").jqGrid({
url : "my-json-table-action' />",
datatype: 'json',
jsonReader: {
root: 'gridModel',
id: 'idTT',
repeatitems: false,
},
resize: false,
hidegrid: false,
data: 'trabajosTerminales',
mtype: 'POST',
height: 'auto',
colNames:['No. de Registro', 'Título', 'Tipo', 'Periodo'],
colModel :[
{name:'numRegistro', index:'titulo', search: 'true', stype:'text', align:'center' searchrules:{required:true}, width:100 },
{name:'titulo', key:'true', index:'titulo', search: 'true', stype:'text', searchrules:{required:true}, width:800 },
{name:'tipo', key:'true', index:'tipo', search: 'true', stype:'text',align:'center', searchrules:{required:true}, width:100 },
{name:'periodo', key:'true', index:'titulo', search: 'true', stype:'text', searchrules:{required:true}, width:100 },
],
pager: '#pager',
rowNum:10,
rowList:[10,20,30],
viewrecords: true,
gridview: true,
caption: 'Trabajos Terminales dirigidos',
});
jQuery("#list").navGrid('#pager',{edit:false,add:false,del:false});
});
Where the root element is the array that contains your data, in this case I'm returning my data in an array called 'gridModel', the id is not necessary. But you have to make sure to set the root element right, in your case it's called 'rows' instead 'gridModel'.

Can't get saveRow aftersavefunc or successFunc to work

I've got some code that, when switching which row is selected, it triggers a save of the previously selected row.
The row is being successfully saved without any problem, however the successfunc isn't being called at all - my console.log output never shows up, and the code in this function isn't being run. I also tried specifying the function as the aftersavefunc, but couldn't get that to work either.
Seems like a simple syntax problem, but I can't quite get it right. Am I not specifying this function properly?
As a side note, I realize that reloading the entire grid after a row save seems like overkill, but in the context of where this particular piece of code is, within the larger structure of my app, this snippet of code is a special case.
The full jqGrid code is:
var lastSelectedMainGridRowID = 0;
var lastSelectedSubGridRowID = 0;
var translationsFeed = "/update/translations/ajax/translations_feed.php";
var translationsEdit = "/update/translations/ajax/translations_edit.php";
var translationsSubGridFeed = "ajax/translations_subgrid_feed.php";
var translationsSubGridFeedEdit = "ajax/translations_subgrid_feed_edit.php";
$(document).ready(function () {
$("#translationsList").jqGrid({

rownumbers : true,
toolbar : [false],
loadComplete: function(data) {
jQuery("#translationsList").setSelection (0, true);
},
colNames : ["phrase_id", "translation_id", "language_cd", "Phrase", "Translation", "Modified", "Created", "Active"],
colModel : [
{ name : "phrase_id", index : "phrase_id", sortable : true, search : false, editable: true, edittype : "text", editrules: { edithidden: true }, hidden: true},
{ name : "translation_id", index : "translation_id", sortable : false, search : false, editable: true, edittype : "text", editrules: { edithidden: true }, hidden: true},

{ name : "Active", width:20, index : "active", sortable : true, search : true, editable: true, edittype: "checkbox", editoptions: {value:"Yes:No", checked: true} }
],
onSelectRow: function(id) {
jQuery('#translationsList').jqGrid('saveRow', lastSelectedMainGridRowID);
jQuery('#translationsList').jqGrid('editRow', id, true);
lastSelectedMainGridRowID = id;
},
subGrid: true,
subGridRowExpanded: function(subgrid_id, row_id) {
var subgrid_table_id;
jQuery("#"+subgrid_id).html("<table id='"+subgrid_table_id+"' class='scroll'></table>");
jQuery("#"+subgrid_table_id).jqGrid({
url: translationsSubGridFeed + "?phrase_id=" + row_id,
editurl: translationsSubGridFeedEdit,
datatype: "xml",
colNames: ['phrase_id', 'translation_id', 'language_cd', 'Translations', 'Language', 'Active'],
colModel: [
{name:"phrase_id", index:"phrase_id", sortable: false, editable: true, edittype : "text", editrules: { edithidden :true }, hidden: true},
{name:"translation_id", index:"translation_id", sortable: false, editable: true, edittype : "text", editrules: { edithidden :true }, hidden: true},
{name:"language_cd", index:"language_cd", sortable: false, editable: true, edittype : "text", editrules: { edithidden :true }, hidden: true},
{name:"Translation", index:"translation", sortable: true, editable: true, edittype:"text", width:589},
{name:"Language", index:"language_disp", sortable: true, editable: false, width:250},
{name:"Active", index:"active", sortable: true, editable: true, edittype:"checkbox", editoptions:{value:"Yes:No", checked: true}, width:80}
],
height: "100%",
rowNum:20,
sortname: 'language_cd',
sortorder: "asc",
onSelectRow: function(id) {
jQuery("#"+subgrid_table_id).jqGrid('saveRow', lastSelectedSubGridRowID, function(response) {
console.log("Data: " + response.responseText);
return false;
});
jQuery("#"+subgrid_table_id).jqGrid('editRow', id, true);
lastSelectedSubGridRowID = id;
}
});
}
});
Perhaps I don't need to use saveRow. In this case, what I'm doing is:
When you click on a row, it becomes editable
If you then click on a second row, the first row is saved (and no longer selected), and the new second row then becomes editable. Similar to saving a row "onBlur", so to speak.
I don't see the place of code where responseData variable are defined. The code responseData[0] should throw an exception, so the console.log("Data: " + responseData[0]); will not display any data. The line of code should be probably fixed as
console.log("Server response: " + result.responseText);
UPDATED: Without having the data for the both grid and for example the subgrid corresponds the first row one can't debug the code. Reading is not so effective. If you posted the test data (two XML files) I could try to localize the problem.
An important error is that you only declare subgrid_table_id variable, but not assign a value for it. Typically one construct an unique id name subgrid_table_id based on the subgrid_id. For example
var subgrid_table_id = subgrid_id+"_t";
instead of var subgrid_table_id; only.
Nevertheless some things I find a little suspected:
I don't understand why you return return false; from the successfunc. It means that you interpret the server response as an error and the normal actions on successful server response should be interrupted. I would recommend you additionally use errorfunc parameter of saveRow. In my server code the server always return error HTML status code in case of the server error. So I never need use successfunc and use aftersavefunc and errorfunc only.
The subgrid has many column which already exist in the corresponding row of the parent grid. The potential problems here are not only spending of additional memory. You don't posted the grid data and so I don't know what values you use as rowids for grids. It is very important to have no id duplicates on the HTML page. So you should be careful in the subject. Why you need ? Probably you can just use extraparam parameter of saveRow and editRow instead of the usage of phrase_id, translation_id and language_cd hidden columns having editable: true, editrules: { edithidden :true }, hidden: true properties?

Jqgrid pager not working with "local" dataType

Does Jqgrid allow us to add pager which we are using dataType local and don't want the whole data to be loaded at once. I am trying to do the same without success. It only shows the first page and show Page 1 Of 1 on the pager when there are many more records to be displayed.
Probably you fill the grid contain in the wrong way. Look at the example to see how you can use data parameter of jqGrid.
I have this same issue. I have a "local" jqgrid setup and it's showing my data but the pager values aren't completely accurate. Until I figured out that I needed to muck with the 'localReader' property. On the jqgrid wiki I saw that the jsonReader can have functions that define how to get the page, records, etc. It also states that the localReader can do whatever the jsonReader does so I gave it shot. Here's what I am doing.
var grid = $('#table').jqGrid({
datatype: 'local',
altRows: true,
colModel: [
{name: '0', label: "Name"},
{name: '1', label: "Color"},
],
pager: "#pager",
rowNum: 15,
sortname: '0',
viewrecords: true,
gridview: true,
height: '100%',
autowidth: '100%'
});
var reader = {
root: function(obj) { return results.rows; },
page: function(obj) { return results.page; },
total: function(obj) { return results.total; },
records: function(obj) { return results.records; },
grid.setGridParam({data: results.rows, localReader: reader}).trigger('reloadGrid');
My "results" is an object like this:
{page: "1", total: "70", records: "1045", rows:[.....]}
This seems to work as desired.
