jqgrid reading form element value and dynamically changing select option - jqgrid

I like to change the Type field drop down option depending on the inputs of Year and Level fields.
I am able to trigger an event when Level is change.
But how do I get the value of the Year field?
Portion of the code are as follows
colModel:[
{name:'Year',index:'Year', width:70,sortable:false,editable:true,align:'center',editoptions:{size:15, maxlength:4}, formoptions:{ rowpos:1, label: "Year (*)"},editrules:{required:true}},
{name:'Level',index:'Level', width:70,sortable:false,editable:true,align:'center',edittype: "select", editoptions: { value: '1:1;2:2;3:3;4:4;5:5;6:6', defaultValue:'1', dataEvents : [
{
'type' : 'change',
'fn' : function ( el ) {
// get the newly selected value from the user
var levelz = $(el.target).val(), yearz ;
var row = $(el.target).closest('tr.jqgrow');
var rowid = row.attr('id');
//yearz = ??
if (parseInt(levelz)==5 || parseInt(levelz)==6)
{
if (parseInt(yearz)>2017)
{
$("#gridmain").jqGrid('setColProp','Term', {editoptions: { value: '1:Sem 1;4:Sem 2;6:EY;9:OVR', defaultValue:'Sem 1'}} );
}else{
$("#gridmain").jqGrid('setColProp','Term', {editoptions: { value: '', defaultValue:''}} );
}
}else{
$("#gridmain").jqGrid('setColProp','Term', {editoptions: { value: '1:TA1/CT1;2:TA2-before 2013;3:MY/TA2/CT2;4:TA3/CT3;5:TA4-before 2013;6:EY/TA4/CT4;9:OVR;D:CW1;E:CW2;F:CW3;G:CW4', defaultValue:'TA1'}} );
}
}
}]}, formoptions:{ rowpos:2, label: "Level (*)"},editrules:{required:true}},
{name:'Term',index:'Term', width:70, sortable:false,editable: true,align:'center',edittype: "select", editoptions: { value: '1:TA1/CT1;2:TA2-before 2013;3:MY/TA2/CT2;4:TA3/CT3;5:TA4-before 2013;6:EY/TA4/CT4;9:OVR;D:CW1;E:CW2;F:CW3;G:CW4', defaultValue:'TA1'}, editrules: { required: true }, formoptions:{ rowpos:3, label: "Type"}},
The codes are from piecing together what I read from google search...
I face 2 issues:
1) I don't know how to get the Year value
2) The drop down option list doesn't seems to change. - hmm it seems that if I close the edit form and open again, the Type field drop down option changes. What I need is to change the option on the fly - wonder how this can be done...

After much googling, managed to get the ans from Oleg's post as shown here
Also from his example, I derive the year value:
var yearz = $("#Year.FormElement", form[0]).val();

KendoGrid - Filtering on a property of object

here is my KendoGrid :
$scope.gridEltCompoOptions = {
dataSource: {
transport: {
...
},
schema: {
model: {
id: 'IdElement',
fields: {
GroupeActes: { defaultValue: { IdGroupeActes: null, Libelle: ' ' } }
}
}
}
},
sortable: true,
resizable: true,
filterable: {
mode: 'row'
},
columns: [{
field: 'GroupeActes',
title: "Groupe d'actes",
template: function (dataItem) {
return kendo.toString(dataItem.GroupeActes.Libelle);
}
}, ]
I want to filter my field 'GroupeActes' on the property Libelle (GroupeActes is an object), but actually the filter take the entire object.
When i try to filter, i have a Js Error
Uncaught TypeError: (d.GroupeActes || "").toLowerCase is not a function
The problem is clear, the filter is taking the entiere object, not the property Libelle.
i passed the last 4 hours to try all the solutions i found on google but nothing is working
my object GroupeActes is like this :
var GroupeActes = {
GroupeActes : {
Libelle : ""
}
}
there is two groupeActes level
I saw a post in 2015 of an Admin, saying this kind of filter isn't possible,
but i saw also this kind of solution :
https://docs.telerik.com/kendo-ui/knowledge-base/grid-filter-column-with-dropdownlist
(if(e.field == "Category" && e.filter !== null){) in the example
i tried to do something like : if field == "groupeActes" => so i want to filter on Libelle properties,
but i didn't success
Can someone help me please ?
thank you so much
Have you looked at this article: https://docs.telerik.com/kendo-ui/knowledge-base/enable-operations-for-object-column
I believe you can accomplish what you want by setting the column field to "GroupeActes.Libelle" instead of using a column template:
columns: [
{
field: 'GroupeActes.Libelle',
title: "Groupe d'actes",
},
],
See this DEMO:

KendoUI Grid custom groupable object

I am trying to make a grid groupable on columns field but the columns are object.
{
Gestionnaire :
{ id: 4, nom:'nomgestionnaire'},
{..},
..
}
I have success for sortable:
columns: [
field: "Gestionnaire"
title: "Gestionnaire"
sortable:
compare: (a,b) =>
#compareColumnFields(a.Gestionnaire.Nom, b.Gestionnaire.Nom)
]
with #compareColumnFields function is :
if a is b
return 0
else if a > b
return 1
else
return -1
and for groupable?
groupable : ...
I think you're wanting to allow the user to actively group columns.
In that case, all you need is:
groupable: true
in the main structure of the grid.
For example:
$('#grid').kendoGrid({
columns: [
{
fields: "Guestionaire",
title: "Guestionaire",
sortable:
compare: (a,b) =>
#compareColumnFields(a.Guestionaire.Nom, b.Guestionaire.Nom)
},
{...placeholder for other columns...}
],
groupable: true
});
Kendo has a sample of this at http://dojo.telerik.com/ejehe
Ignore the SelectRow and Expand/Collapse stuff and that ought to be the same as what you're trying to accomplish.
For those in the same situation as me , I completely change solution. Instead of making me a function that returns true and false , it giving it the object in full, I just give the string .
For my example I give directly a.Gestionnaire.Nom and b.Gestionnaire.Nom, and THEN you can call :
groupable: true
In fact it was obvious.

ID values for jqGrid select lists

I am using jQrid version 3.8.1 and I have a grid that displays information about cars. The jQgrid should is set up to display one car per row and one of the columns is a multi-select list that displays which types of seats the car is configured with. A car can have multiple seat types.
When the user edits a car row, it makes an ajax query to get all of the seats types available in the system and sticks them in the multi-select list. In addition to populating the list, it needs to also select the options already chosen for that car.
The values inside the Installed Seats column are not simple strings. They have both an ID and a string value. So the ID for "Wire mesh" might be 2883 and the value for "Composite" might be 29991. They are just unique numeric values (basically the primary key from the table they are stored in).
After the multi-select list is populated with all the appropriate Seat values, I need to select the ones that the car currently has installed (in the picture above it's "Steel" and "Wire frame"). I need to do this based on the seat IDs stored for that car. However, I don't know where these value are going to come from. The grid only stores the names for the seats, not the IDs. Hopefully there is a way to make it store both.
The column model looks like this:
colModel: [
{ name: 'Year', index: 'Year', editable: true, edittype: "select", editoptions: { multiple: true } },
{ name: 'Make', index: 'Make', editable: true, edittype: "select", editoptions: { multiple: true } },
{ name: 'Body', index: 'Body', editable: true, edittype: "select", editoptions: { multiple: true } },
{ name: 'Seats', index: 'Seats', editable: true, edittype: "select", editoptions: { multiple: true }, cellattr='is-seat-list="1"' }
]
Notice that the 'Seats' model has a cell attribute called is-seat-list. I'm using this to find the select box in the row inside the 'editRow' function.
The onSelectRow handler looks like this:
onSelectRow: function (index) {
var curValues = $('#cargrid').getRowData(index);
jQuery('#cargrid').jqGrid('editRow', index, true, function(rowId) {
//when the user edits the row, query for all the seat types and fill in the list
jQuery.ajax({
url: '/getalltheseats',
complete: function (allSeats, stat) {
var list = $('#cargrid').find('tr[id="' + rowId + '"] td[is-seat-list="1"] select');
var $list = $(list);
//add the all seat types to the list, checking the ones that this car currently has selected
_.each(allSeats, function(seat) {
var selected = '';
if(curValues['Seats'].indexOf(seat.ID) !== -1) //<-- what do I do here??
selected = 'selected';
$list.append($('<option ' + selected + '></option>').attr('value', seat.ID).text(seat.Name));
});
});
});
});
},
The important line is
if(curValues['Seats'].indexOf(seat.ID) !== -1)
I have the value of the row but it only contains the seat name, not the ID. The data returned from the ajax call contains each seat name and ID but the <option> elements don't contain the ID value so I don't know which ones to select in the list.
So the question is, what's the best way to make jqGrid store both the seat names and IDs so that when I create the list dynamically, I can check the <option>s for the seats that have been chosen for that car.
Note:
For various reasons the standard dataUrl and buildSelect features of jqGrid are not going to work for me, which is why I'm building the list on the fly in this manner.
First of all you need additionally add formatter: "select" and to populate ID values in Seats column during filling of the grid. The formatter: "select" will decode the IDs and the corresponding Name value will be displayed to the user.
If you would use more recent version of jqGrid the you can use beforeProcessing callback created for the purpose. It allows to include all different ID/Name pairs in the server response for filling of the grid. It allows you to fill the information needed for the formatter: "select" directly in the main server response. You don't need to load the information before creating the grid.
If you use retro version of jqGrid (3.8.1) then I hope that you can still use the following trick. You can define userdata part of the server response defined as function. The outer elements of the server response root, page, total, records and userdata will be processed before the processing the main part with all items. It allows you to modify editoptions.value before it will be processed by formatter: "select".
For example the response from the server can looks like
{
"page": 1,
"total": 20,
"records": 400,
"userdata": {
"seats": "29991:Composite;42713:Nappa leather;6421:Steel;2883:Wire mesh"
},
"rows": [
{
"year": 2007,
"model": "Toyota/Camry",
"body": "Sedan",
"seats": "29991,6421"
},
{
"year": 2057,
"model": "BMW/Series 4",
"body": "Sedan",
"seats": "6421,2883"
}
]
}
Inside of jsonReader you can define userdata which set userdata.seats as value of editoptions. You can use setColProp method for example to do this.
In the way you will be able to implement all your requirements.

Sorting a Column by Default (on load) Using Dojo Dgrid

When loading a dgrid from a dojo store, is there a way to specify a column to be sorted by default.
Say I have 2 columns, Name and Email, I want the name column sorted by default when the grid is first loaded. What I want is the equivalent of the user clicking on the 'Name' header (complete with the sort arrow indicating the sort direction).
Thanks,
John
You can do something like this :
var mygrid = new OnDemandGrid({
store : someStore,
queryOptions: {
sort: [{ attribute: "name" }]
}
// rest of your grid properties
}, "someNode");
dgrid 1.1.0 - set initial/default sort order
var TrackableRest = declare([Rest, SimpleQuery, Trackable]);
var store = new TrackableRest({target: apiUrl, useRangeHeaders: true, idProperty: 'id'});
var grid = new (declare([OnDemandGrid, Selection, Editor]))({
collection: store,
sort: [{"property":"name", "descending": false}],
className: "dgrid-autoheight",
columns: {
id: {
label: core.id
},
category_text: {
label: asset.category
},
name: {
label: asset.model,
},

Sorting in Dojo 1.5 datagrid doesn't work

I have built a dojo 1.5 datagrid + dojox.data.JsonRestStore. When the grid renders I can see the "carrot" that shows that sorting has fired and is on defaulting the right column. However, the content of the column(string values - field: 'projectShortName',...see code below) are not actually sorted. Hitting the descending/ascending button doesn't change the order or the rows. They are essentially locked in. I am not sure why?
I have column sorting turned off for certain columns and on for others using the canSort(). I only have formatters for calls with columns that have the sort turned OFF. I have tried making all columns sortable or only just the one that I really wanted. No dice.
Here is the layout/grid code:
var layout = [{
field: '_item',
name: '&nbsp',
formatter: selectFormatter,
width: '25px'
},
{
field: 'projectName',
name: 'Project Name',
width: '325px'
},
{
field: 'projectShortName',
name: 'Short Name',
width: '80px'
},
{
field: 'projectAreaName',
name: 'RQM Project Area',
width: '175px'
},
{
field: '_item',
name: 'Test Guide Status',
width: '190px',
formatter: testCaseGenerationOptionFormatter
},
{
field: 'projectOwner',
name: 'Owner',
width: '140px'
},
{
field: 'projectCreationTime',
name: 'Created Date',
width: '100px'
},
{
field: 'projectLastUpdateTime',
name: 'Last Modified Date',
width: '120px'
}];
dojo.empty(dojo.byId('workspaceGridContainer'));
if (dijit.byId("projectGrid")) {
dijit.byId("projectGrid").destroyRecursive();
}
// Create a new grid:
var grid = new dojox.grid.DataGrid({
id:'projectGrid',
onHide: dojo.hitch(this, function() {
dijit.byId("projectGrid").destroyRecursive();
}),
store: jsonStore,
clientSort: true,
autoHeight: true,
//sortInfo: "-2",
selectionMode: 'single',
rowsPerPage: '100',
structure: layout
},document.createElement('div'));
dojo.byId("workspaceGridContainer").appendChild(grid.domNode);
// Call startup, in order to render the grid:
grid.startup();
//var test = grid.setSortInfo(obj);
// Prevent sorting on column 1
grid.canSort = function(col){ if((Math.abs(col) == 1) || (Math.abs(col) == 5) || (Math.abs(col) == 6) || (Math.abs(col) == 7) || (Math.abs(col) == 8)) { return false; } else { return true; } };
var index = grid.getSortIndex();
if(index!=2) {
if(grid.canSort(2)){
grid.setSortIndex(2, false);
}
}
As you can see commented out I have tried sortInfo as well. Any advice would be appreciated!

You may be using the wrong comparison operator. The dojo documentation uses the strict equal '===' whereas you only use the equal '=='. This causes problems in js, especially when you're comparing a literal, i.e. '1' with an object: 'Math.abs(col). The official grid.canSort method should be coded as follows:
function canSort(col){ return Math.abs(col) === 2;}
Note Mozilla's description of the equal operator, and the type conversion js uses to resolve different data types:
https://developer.mozilla.org/en/JavaScript/Reference/Operators/Comparison_Operators
Equal (==) - If the two operands are not of the same type, JavaScript converts the operands then applies strict comparison. If either operand is a number or a boolean, the operands are converted to numbers if possible; else if either operand is a string, the other operand is converted to a string if possible. If both operands are objects, then JavaScript compares internal references which are equal when operands refer to the same object in memory.
