I have two slickgrid and one delete button,
When i click on delete,i want focused grid so that i will delete items.
How to get focused grid ?
This is what i have done so far....
function deleteRow(e, args){
//code to delete items from "grid"
var selectedrows = grid.getSelectedRows();
var len = selectedrows.length;
var itemNo = "";
for(var i=0;i<len;i++)
{
var data = grid.getData().getItem(selectedrows[i]);
dataView.deleteItem(data.id);
itemNo =data.id;
var url = "delete_Item_Master?itemNo="+itemNo;
$.get(url, {itemNo : itemNo},function(data) {
location.reload(true);
});
}
//code to delete items from "metalGrid"
var metalSelectedrows = metalGrid.getSelectedRows();
var mlen = metalSelectedrows.length;
var itemNo = "";
for(var i=0;i<mlen;i++)
{
var mData = metalGrid.getData().getItem(metalSelectedrows[i]);
meyalDataView.deleteItem(mData.id);
itemNo =mData.id;
var url = "delete_subItem?itemNo="+itemNo;
$.get(url, {itemNo : itemNo},function(data) {
location.reload(true);
});
}
}
But this code delete items from both grid..
I think that the correct way to do this is to write your own selection model. It should be a Singleton, and two grids should interact with it. It should know which grid was last active.
But you need to ask yourself is that behaviour is good. What if user will delete an item from another grid - because there's only one button. IMHO every grid should have it's own button. And I work for an ERP company where we got that dillemas everyday ;)

Anyone please tell me how can i select next consecutive row from first page to second page of my kendo grid and reverse back to the previous page ? Kendo Grid API just only gives me information on 'select' and from there I have no clue at all how to implement my desired selection. What I have now is only selecting the row of the selected/active cell. Any insight/references are also appreciated. So far I haven't came across with any examples or article.
var data = $("#grid").data('kendoGrid');
var arrows = [38,40];
data.table.on("keydown", function (e) {
if (arrows.indexOf(e.keyCode) >= 0) {
setTimeout(function () {
data.clearSelection();
data.select($("#grid_active_cell").closest("tr"));
},1);
}
});
http://dojo.telerik.com/eSUQO
var data = $("#grid").data('kendoGrid');
var arrows = [38,40];
var navrow_uid; ** add this tracking variable;
data.table.on("keydown", function (e) {
if (arrows.indexOf(e.keyCode) >= 0) {
setTimeout(function () {
data.clearSelection();
// break this up
// data.select($("#grid_active_cell").closest("tr"));
// fetch next row uid and compare to tracker
var nextrow = $("#grid_active_cell").closest("tr");
var uid = nextrow.data('uid');
if (navrow_uid == uid ) {
console.log("last navigable row");
data.dataSource.page(1+data.dataSource.page());
// best option here would be to set auto-page flag for databound event handler
} else {
data.select(nextrow);
navrow_uid = uid;
}
},1);
}
});
You will want to add a grid data bound handler, and have that check the aut-page flag to see if you need to select first or last row of page.
I am using openlayers 3. From the values contained in a vector GeoJSON, I want to fill a dropdown menu. When selecting a value from the dropdown menu, I want to zoom in on the entity.
My problem now is that I want to generate my HTML from the attributes of my GeoJSON. So I tried this simple code but it doesn't work :
var menu = document.getElementById('menuDropDown');
vector2.getSource().forEachFeature(function() {
menu.innerHTML = feature.get('NOM').join(', ');
});
EDIT:
I'm able to populate a dropdown menu from a list:
var list = ['a','b','c'];
var mySelect = $('#mySelect');
$.each(list, function(val, text) {
mySelect.append(
$('<option></option>').val(val).html(text)
);
});
What i want to do it's to populate this list from the attribute of my vector
So i try this:
// vector2 it's a GeoJSON who is integrate on my map
vector2.getSource().getFeatures().forEachFeature(function(feature) {
list.push(feature.get('NOM'));
});
Firstly I'm assuming you have to pass some parameter to your callback:
vector2.getSource().forEachFeature(function(feature) {
Then you can append an item to a dropdown like so:
var item = document.createElement('option');
item.setAttribute('value', feature.get('NOM'));
var textNode = document.createTextNode(feature.get('NOM'));
item.appendChild(textNode)
menu.appendChild(item);
All together:
var menu = document.getElementById('menuDropDown');
vector2.getSource().forEachFeature(function(feature) {
var item = document.createElement('option');
item.setAttribute('value', feature.get('NOM'));
var textNode = document.createTextNode(feature.get('NOM'));
item.appendChild(textNode)
menu.appendChild(item);
});
I have resolve my problem:
vector2.getSource().on('change', function(evt){
var source = evt.target;
var list = [];
source.forEachFeature(function(feature) {
list.push(feature.get('NOM'));
});
// console.log("Ecrit moi les noms : " + list);
Thanks you to those who took the time to respond
I have a problem which I cannot seem to solve. I need to create a function which loops over an array of datasets and creates an independent slickgrids for each dataset. The catch is that the functions need to be bound to each grid independently. For example:
// this part works fine
for(var i=0; i<domain.length; i++){
dataView = new Slick.Data.DataView();
grid = new Slick.Grid('#' + domain[i].name, dataView, domain[i].columns, domain[i].options);
var data = domain[i].data;
// this works well and I am able to create several slickgrid tables
... etc ...
The problem is that every grid is now called "grid". Therefore, when I bind a function like this:
// controls the higlighting of the active row
grid.highlightActiveRow = function () {
var currentCell;
currentCell = this.getActiveCell();
I get a result which affects all grids (or in some cases only one grid).
How do I create multiple, independent grids with associated functions??? The problems seems to be that I have created one object "grid" and then assign all functions using the syntax grid.xxx - but I dont know how to create a unique object on each itteration.
Any help would be most appreciated.
PS: slickgrid is just amazing!!
Thanks

Thank you both for your help. Here is where I have manged to get to:
var dataView;
function buildTable() {
for(i = 0; i<domains.length; i++){
dataView = new Slick.Data.DataView();
var d = domains[i];
grid = new Slick.Grid('#' + d.name, dataView, d.columns, grids.options);
var data = d.data;
grid.init();
dataView.beginUpdate();
dataView.setItems(data);
// dataView.setFilter(filter); -- will be reinstated once i have this working
dataView.endUpdate();
arrOfGrids.push(grid);
};
};
Jakob - for now i am sticking to "for(i)" until I can wrap my head around your comment - which seems very sensible.
But, using the above, the grid data are not populating. I am not getting any js errors and the column headers are populating but not the data. The reference to d.data is definitely correct as I can see the data using the Chrome js debugger.
Any ideas? Many thanks for your help so far
Instead of assign all new grids to grid (in which case you overwrite the old one everytime you create a new one), push them to an array:
var arrayOfGrids = [];
for(var i=0; i<domain.length; i++) {
dataView = new Slick.Data.DataView();
arrayOfGrids.push(new Slick.Grid('#' + domain[i].name, dataView, domain[i].columns, domain[i].options));
// ....
Then, when you want to something with your grids, like adding the highlight-function, you loop over the array and do it for each element:
for ( var i=0; i<arrayOfGrids.length; i++ ) {
arrayOfGrids[i].highlightActiveRow = function () {
var currentCell;
currentCell = this.getActiveCell();
// ... etc...
BONUS
While we're at it, I would recommend that you use the forEach method that's available on the array-object when iterating over the arrays, rather than the for-loop. The unlike the loop, forEach creates a proper scope for your variables and it gets rid of the useless i-iteration variable:
var arrayOfGrids = [];
domain.forEach(function(d) {
dataView = new Slick.Data.DataView();
arrayOfGrids.push(new Slick.Grid('#' + d.name, dataView, d.columns, d.options));
// ....
And then the same for the other loop of course :)
You could try adding each of the grid instances to an array.You will be able to handle each of the grids differently if you want, by means of <arrray>[<array-index>]
var gridArr = [];
// this part works fine
for(var i=0; i<domain.length; i++){
dataView = new Slick.Data.DataView();
var grid = new Slick.Grid('#' + domain[i].name, dataView, domain[i].columns, domain[i].options);
var data = domain[i].data;
// this works well and I am able to create several slickgrid tables
... etc ...
gridArr.push(grid)
Then if you say gridArr[0] you can access the 1st grid,gridArr[1] second grid and so on.
Just in case anybody else is following this question - here is the working solution:
Many many thanks to #Jokob and #user700284
// default filter function
function filter(item) {
return true; // this is just a placeholder for now
}
var dataView;
function buildTables() {
for(i = 0; i<domains.length; i++){
dataView = new Slick.Data.DataView();
var d = domains[i];
grid = new Slick.Grid('#' + d.name, dataView, d.columns, options);
var data = d.data;
grid.init();
dataView.beginUpdate();
dataView.setItems(data);
dataView.setFilter(filter);
dataView.endUpdate();
grid.invalidate();
grid.render();
arrOfGrids.push(grid);
};
};
The aim is to remove only the last row at any time and only by the last remove button.
There is a user interface which building up as a multiplication of the same row. The number of rows are controlled by 'Add' & 'Remove' buttons which are also elements of the row. The problem is that the hidden widgets - that are applied for each row to distinguish the instances by storing their row numbers - are storing the very same number which is the last one. Except the first (0) hidden widget which stores the proper number (0). Where am I missing the point? How should this be resolved?
As per the remove buttons have two different purposes (not detailed here), we use a cacheService to distinguish the last row from all the others. Only the last row should be removed at any time.
var cache = CacheService.getPrivateCache();
we clear the cache and create the first instance
function doGet() {
var app = UiApp.createApplication();
app.add(app.createVerticalPanel().setId('mainContainer'));
cache.removeAll([]);
ui(0);
cache.put('numberOfInstances',0);
return app; }
each instance is held by a horizontal panel which contains the mentioned hidden widget, a label which informs about the instance number, and the Add & Remove buttons.
function ui(instance) {
var app = UiApp.getActiveApplication();
var eventContainer = app.createHorizontalPanel()
.setId('eventContainer' + instance);
var instanceContainer = app.createHidden('instanceContainer',instance);
var showInstance = app.createLabel(instance)
.setId('showInstance' + instance);
var addButton = app.createButton('Add')
.setId('add' + instance)
.addClickHandler(app.createClientHandler()
.forEventSource().setEnabled(false)) //avoiding multiple click during server response
.addClickHandler(app.createServerHandler('add')
.addCallbackElement(instanceContainer));
var removeButton = app.createButton('X')
.addClickHandler(app.createServerHandler('remove')
.addCallbackElement(instanceContainer));
app.getElementById('mainContainer')
.add(eventContainer
.add(instanceContainer)
.add(showInstance)
.add(addButton)
.add(removeButton));
return app; }
and the event handling...
function add(inst) {
var app = UiApp.getActiveApplication();
var instance = Number(inst.parameter.instanceContainer);
ui(instance+1);
cache.put('numberOfInstances',instance+1);
return app; }
function remove(inst) {
var app = UiApp.getActiveApplication();
var instance = Number(inst.parameter.instanceContainer);
var numberOfInstances = cache.get('numberOfInstances')
if( (instance != 0) && (instance = numberOfInstances) ) {
app.getElementById('mainContainer').remove(app.getElementById('eventContainer' + instance));
cache.put('numberOfInstances',instance-1);
app.getElementById('add' + (instance-1)).setEnabled(true); } //avoiding multiple click during server response
return app; }
The aim is to remove only the last row at any time and only by the last remove button.
Many Thanks.
Why don't you simply use a clientHandler just as you did on the 'add' button? You could target the preceding 'remove' button and disable it each time you create a new one and change /update each time you remove one row.
EDIT : I can suggest you something, feel free to have a look, I changed a bit the approach but it is working and I hope you'll find it at least interesting ;-)
Link to the online test
function doGet() {
var app = UiApp.createApplication();
var counter = app.createHidden().setName('counter').setId('counter').setValue('1');
var mainContainer = app.createVerticalPanel().setId('mainContainer')
app.add(mainContainer.add(counter));
var event1Container = app.createHorizontalPanel()
var showInstance = app.createLabel('1')
var addButton = app.createButton('Add')
.setId('add1')
.addClickHandler(app.createClientHandler()
.forEventSource().setEnabled(false)) //avoiding multiple click during server response
.addClickHandler(app.createServerHandler('add')
.addCallbackElement(mainContainer));
var removeButton = app.createButton('X')
.setId('remove1')
.addClickHandler(app.createServerHandler('remove')
.addCallbackElement(mainContainer));
mainContainer.add(event1Container
.add(showInstance)
.add(addButton)
.add(removeButton));
return app; }
function add(inst) {
var app = UiApp.getActiveApplication();
var hiddenVal =inst.parameter.counter;
var counterVal = Number(hiddenVal);
var mainContainer = app.getElementById('mainContainer')
var counter = app.getElementById('counter')
++ counterVal
counter.setValue(counterVal.toString())
var eventContainer = app.createHorizontalPanel().setId('eventContainer'+counterVal)
var showInstance = app.createLabel(counterVal.toString())
var addButton = app.createButton('Add')
.setId('add'+counterVal)
.addClickHandler(app.createClientHandler()
.forEventSource().setEnabled(false)) //avoiding multiple click during server response
.addClickHandler(app.createServerHandler('add')
.addCallbackElement(mainContainer));
var removeButton = app.createButton('X')
.setId('remove'+counterVal)
.addClickHandler(app.createServerHandler('remove')
.addCallbackElement(mainContainer));
app.add(eventContainer
.add(showInstance)
.add(addButton)
.add(removeButton));
if(counterVal>1){app.getElementById('remove'+(counterVal-1)).setEnabled(false)}
return app; }
function remove(inst) {
var app = UiApp.getActiveApplication();
var counterVal = Number(inst.parameter.counter);
var counter = app.getElementById('counter')
if(counterVal ==1) {return app}
var maincontainer = app.getElementById('mainContainer')
app.getElementById('eventContainer' + counterVal).setVisible(false)
--counterVal
counter.setValue(counterVal.toString())
app.getElementById('add'+counterVal).setEnabled(true)
app.getElementById('remove'+counterVal).setEnabled(true)
return app;
}
NOTE : I didn't make use of .remove(widget) since this is a fairly new method and I don't know exactly how it works... I'll test it later. Until then I used setVisible(false) instead, sorry about that :-)
Note 2 : I didn't use the cache since the hidden widget is sufficient to keep track of what is going on... if you needed it for something else then you could always add it back .
hai i am very new to jquery and jqgrid..
i have implemented a grid...but i don't have any idea to display images in column from the corresponding database value...i tried a lot but failed ..can anybody help me..
regards
In the setup parameters add:
loadComplete: function() {
var ids = $("#list").getDataIDs();
for (var i = 0; i < ids.length; i++) {
var cl = ids[i];
be = "<img src='http://www.google.com/images/nav_logo6.png'>";
$("#list").setRowData(ids[i], { externalId: be })
}
},
In this example it will load the google logo. This sample goes over all the rows and adds the same item. You can change it do be more dynamic based on the current value of the cell etc.
