populating input field with row data when row is clicked on

How can i populate form inputs with the row data of a row that is clicked on? (using AG GRID and vanilla JS)
Example code would be appreciated
const gridOptions = {
columnDefs: [
{field: "make", sortable: true, filter: true},
{field: "model", sortable: true, filter: true},
{field: "price", sortable: true, filter: true}
],
rowData: [
{make: "VW", model: "Jetta", price: "$25,000"},
{make: "Honda", model: "Odyssey", price: "$35,000"},
{make: "Audi", model: "Q2", price: "$45,000"}
],
animateRows: true,
onCellClicked: params => {
let dataMake = params.data.make;
console.log(dataMake);
const fillInput = (e) => {
e.preventDefault()
const input1 = document.querySelector("#input1").value
console.log(input1);
input1 = "dataMake"
}
}
};
new agGrid.Grid(eGridDiv, gridOptions)
fetch("https://www.ag-grid.com/example-assets/row-data.json")
.then(res => res.json())
.then(data => {
gridOptions.api.setRowData(data)
});

I'm assuming that you know how to set values in your form, and that you're just asking how to get the data from the grid.
So, if I understand correctly, you're asking about filling in multiple form fields, corresponding to multiple cells in grid row, when the row is clicked.
Your code looks correct except that you are using the onCellClicked property where you should be using onRowClicked.
With onCellClicked the param to the callback is the data backing the cell that was clicked, while with onRowClicked the param is the object backing the entire row.

ExtJS create elements dynamically based on store items

Is it possible to create some other elements except Ext.panel.Grid using store property?
For example. Lets say that I have a panel:
Ext.create('Ext.panel.Panel', {
layout: 'vbox',
scrollable: true,
items: [
myItemsFunction()
]
}));
And from the backend I get this response:
{
"rows": [
{
"CreateDateTime": "2015-02-09 14:05:46",
"Name": "de.txt",
"id": "1"
},
{
"CreateDateTime": "2015-02-09 14:05:46",
"Name": "en.txt",
"id": "2"
},
{
"CreateDateTime": "2015-02-09 14:05:46",
"Name": "it.txt",
"id": "3"
}]
}
which I load in the store:
var store_documents = Ext.create('Ext.data.Store', {
remoteSort: true,
remoteFilter: true,
proxy: {
type: 'ajax',
api: {
read: baseURL + '&SubFunc=Documents&Action=view',
},
reader: { type: 'json', rootProperty: 'rows', totalProperty: 'total' }
},
autoLoad: true
});
Now, lets say that I want to have download buttons for these three files (de.txt, en.txt, it.txt). How can I create them dynamically based on store items? I want to put it in this myItemsFunction() and show it in panel items (first block of code sample)?
Or a store is only possible to bind with Grid?

You can use ExtJs store without binding it to a grid, because Ext.data.Store has a proxy which act as ajax request when you call store.load().
So you can find this working example ExtJs Fiddle
the basic idea is to define a new panel class and to use initComponent() function to allow you to create dynamic items based on the data retrieved from the request
app.js
Ext.application({
name: 'Fiddle',
launch: function () {
var storeData = {};
let store = Ext.create('Ext.data.Store', {
storeId: 'myStoreId',
fields: ['id', 'name'],
proxy: {
type: 'ajax',
url: 'app/data.json',
reader: {
type: 'json',
rootProperty: 'rows'
}
}
});
store.load(function(){
storeData = this.getData().items;
Ext.create('Fiddle.MyPanel',{panelData:storeData});
});
}
});
app/MyPanel.js
Ext.define('Fiddle.MyPanel', {
extend: 'Ext.panel.Panel',
renderTo: Ext.getBody(),
title: 'Dynamic button creation',
width: 600,
height: 300,
initComponent: function () {
let panelItems = [];
//Creating items dynamicly
for (btn in this.panelData) {
let me = this;
panelItems.push(
Ext.create('Ext.button.Button', {
text:me.panelData[btn].data.Name
})
);
}
this.items = panelItems;
//must call this.callParent()
this.callParent();
}
})
app/data.json
{
"rows": [
{
"CreateDateTime": "2015-02-09 14:05:46",
"Name": "de.txt",
"id": "1"
},
{
"CreateDateTime": "2015-02-09 14:05:46",
"Name": "en.txt",
"id": "2"
},
{
"CreateDateTime": "2015-02-09 14:05:46",
"Name": "it.txt",
"id": "3"
}]
}

Define a controller for you panel;
create an event function for afterrender;
inside it, load your store;
pass a callback parameter to your store's load function, where you iterate over loaded data creating button components;
call this.getView().add(button) to add your buttons to your panel items attribute

use of onCellWidgetCreated in Dojo Gridx (to add button to cell)

I try to add a button to the last column of my Gridx, however, the button is not shown and above the other table data the grid just says "loading...".
Cell Widget is required and declared, widgetInCell is set and onCellWidgetCreated function added. When replacing the onCellWidgetCreated function with alert, an alert message for each row is shown and the "loading..." disappears. My feeling is that the onCellWidgetCreated function is wrong?
My code looks like the following and when comparing it against some examples on the Gridx website I cannot find the problem.
require([
"gridx/Grid",
"gridx/core/model/cache/Sync",
"dojo/store/Memory",
"dojo/domReady!",
"gridx/modules/CellWidget",
"dijit/form/Button"
], function(Grid, Cache, Memory,Button,CellWidget,domConstruct){
var store = new Memory({
idProperty:"CategoryID",
data: jsondata
});
var grid = new Grid({
id:"gridId",
store: store,
cacheClass: Cache,
structure: [
{
id: "0",
field: "CategoryID",
name: "Kategorie (ID)",
width: "100px"
},
{
id: "1",
field: "CategoryName",
name: "Kategoriename"
},
{
id: "2",
field: "Attributes",
name: "Attribute"
},
{
id: "3",
field: "Actions",
name: "Aktion",
widgetsInCell: true,
onCellWidgetCreated: function(cellWidget, column){
var btn = new Button({
label: "Click me!"
});
btn.placeAt(cellWidget.domNode);
}
}
],
modules: [
CellWidget
]
});
grid.placeAt("aGrid");
grid.startup();
}
);

I came across anotheer problem with VirtualVScrolling and found out that this was due to a defective gridx css file which contained a custom layout.
When using the standard css file, "onCellWidgetCreated" worked for me as well.

ExtJS 4.1 Infinite Grid Scrolling doesnt work with Dynamic store using loadData

I have to load first grid panel on tab and then load data into store using loadData() function which is working fine, but now I have to integrate infinite grid scrolling with it.
Is there any way to integrate infinite scrolling on fly after loadData into store..? I am using ExtJS 4.1. Please help me out.
Here I am showing my current script in controller and grip view panel in which I have tried out but not working.
Controller Script as below:
var c = this.getApplication().getController('Main'),
data = c.generateReportGridConfiguration(response,true),
tabParams = {
title: 'Generated Report',
closable: true,
iconCls: 'view',
widget: 'generatedReportGrid',
layout: 'fit',
gridConfig: data
},
generatedReportGrid = this.addTab(tabParams);
generatedReportGrid.getStore().loadData(data.data);
On Above script, once I get Ajax call response, adding grid panel with tabParams and passed data with gridConfig param which will be set fields and columns for grid and then last statement supply grid data to grid. I have tried out grid panel settings by following reference example:
http://dev.sencha.com/deploy/ext-4.0.1/examples/grid/infinite-scroll.html
On above page, Included script => http://dev.sencha.com/deploy/ext-4.0.1/examples/grid/infinite-scroll.js
My Grid Panel Script as below:
Ext.define('ReportsBuilder.view.GeneratedReportGrid', {

initComponent: function() {
Ext.define('Report', {extend: 'Ext.data.Model', fields: this.gridConfig.fields, idProperty: 'rowid'});
var myStore = Ext.create('Ext.data.Store', {model: 'Report', groupField: 'name',
// allow the grid to interact with the paging scroller by buffering
buffered: true,
pageSize: 100,
autoSync: true,

},

features: [
{ftype: 'groupingsummary', groupHeaderTpl: '{name} ({rows.length} Record{[values.rows.length > 1 ? "s" : ""]})', enableGroupingMenu: false}
],
renderTo: Ext.getBody()
});
// trigger the data store load
myStore.guaranteeRange(0, 99);
this.callParent(arguments);
}
});
I have also handled start and limit from server side query but it will not sending ajax request on scroll just fired at once because pageSize property in grid is 100 and guaranteeRange function call params are 0,99 if i will increased 0,299 then it will be fired three ajax call at once (0,100), (100,200) and (200,300) but showing data on grid for first ajax call only and not fired on vertical scrolling.
As, I am new learner on ExtJs, so please help me out...
Thanks a lot..in advanced.

You cannot call store.loadData with a remote/buffered store and grid implementation and expect the grid to reflect this new data.
Instead, you must call store.load.
Example 1, buffered store using store.load
This example shows the store.on("load") event firing.
http://codepen.io/anon/pen/XJeNQe?editors=001
;(function(Ext) {
Ext.onReady(function() {
console.log("Ext.onReady")
var store = Ext.create("Ext.data.Store", {
fields: ["id", "name"]
,buffered: true
,pageSize: 100
,proxy: {
type: 'rest'
,url: '/anon/pen/azLBeY.js'
reader: {
type: 'json'
}
}
})
store.on("load", function(component, records) {
console.log("store.load")
console.log("records:")
console.log(records)
})
var grid = new Ext.create("Ext.grid.Panel", {
requires: ['Ext.grid.plugin.BufferedRenderer']
,plugins: {
ptype: 'bufferedrenderer'
}
,title: "people"
,height: 200
,loadMask: true
,store: store
,columns: [
{text: "id", dataIndex: "id"}
,{text: "name", dataIndex: "name"}
]
})
grid.on("afterrender", function(component) {
console.log("grid.afterrender")
})
grid.render(Ext.getBody())
store.load()
})
})(Ext)
Example 2, static store using store.loadData
You can see from this example that the store.on("load") event never fires.
http://codepen.io/anon/pen/XJeNQe?editors=001
;(function(Ext) {
Ext.onReady(function() {
console.log("Ext.onReady")
var store = Ext.create("Ext.data.Store", {
fields: ["id", "name"]
,proxy: {
type: 'rest'
,reader: {
type: 'json'
}
}
})
store.on("load", function(component, records) {
console.log("store.load")
console.log("records:")
console.log(records)
})
var grid = new Ext.create("Ext.grid.Panel", {
title: "people"
,height: 200
,store: store
,loadMask: true
,columns: [
{text: "id", dataIndex: "id"}
,{text: "name", dataIndex: "name"}
]
})
grid.on("afterrender", function(component) {
console.log("grid.afterrender")
})
grid.render(Ext.getBody())
var data = [
{'id': 1, 'name': 'Vinnie'}
,{'id': 2, 'name': 'Johna'}
,{'id': 3, 'name': 'Jere'}
,{'id': 4, 'name': 'Magdalena'}
,{'id': 5, 'name': 'Euna'}
,{'id': 6, 'name': 'Mikki'}
,{'id': 7, 'name': 'Obdulia'}
,{'id': 8, 'name': 'Elvina'}
,{'id': 9, 'name': 'Dick'}
,{'id': 10, 'name': 'Beverly'}
]
store.loadData(data)
})
})(Ext)

Creating a Dynamic Grid with ExtJS

I'm trying to make a Dynamic Grid class (where I do not know any information about the columns but they are given from the json response and the gird prepares itself accordingly). Here I have found exactly what I was looking for however it gives me an error:
me.model is undefined
me.setProxy(me.proxy || me.model.getProxy());
ext-all-debug.js (line 47323)
I have tried to add both proxy and model but I was not successful, I kept getting the same error.
Here is the ExtJS code that I'm working on:
// ExtJS 4.1
Ext.Loader.setConfig({
enabled: true
});
Ext.Loader.setPath('Ext.ux', '../extjs-4.1.0/examples/ux');
Ext.require([
'Ext.grid.*',
'Ext.data.*', ]);
Ext.define('DynamicGrid', {
extend: 'Ext.grid.GridPanel',
storeUrl: '',
enableColumnHide: true,
initComponent: function () {
var store = new Ext.data.Store({
url: this.storeUrl,
reader: new Ext.data.JsonReader(),
autoLoad: true,
scope: this,
listeners: {
scope: this,
metachange: function (store, meta) {
if (typeof (store.reader.jsonData.columns) === 'object') {
var columns = [];
/**
* Adding RowNumberer or setting selection model as CheckboxSelectionModel
* We need to add them before other columns to display first
*/
if (this.rowNumberer) {
columns.push(new Ext.grid.RowNumberer());
}
if (this.checkboxSelModel) {
columns.push(new Ext.grid.CheckboxSelectionModel());
}
Ext.each(store.reader.jsonData.columns, function (column) {
columns.push(column);
}); // Set column model configuration
this.getColumnModel().setConfig(columns);
this.reconfigure(store, this.getColumnModel());
}
}
}
});
var config = {
title: 'Dynamic Columns',
viewConfig: {
emptyText: 'No rows to display'
},
loadMask: true,
border: false,
stripeRows: true,
store: store,
columns: []
}
Ext.apply(this, config);
Ext.apply(this.initialConfig, config);
DynamicGrid.superclass.initComponent.apply(this, arguments);
},
onRender: function (ct, position) {
this.colModel.defaultSortable = true;
DynamicGrid.superclass.onRender.call(this, ct, position);
}
});
Ext.onReady(function () {
Ext.QuickTips.init();
var grid = Ext.create('DynamicGrid', {
storeUrl: 'http://300.79.103.188/ApplicationJs/jsontest.json'
});
var depV = Ext.create('Ext.Viewport', {
title: 'Departman Tanımları',
layout: 'fit',
items: grid
}).show();
});
What I have to do inorder to make it run?

That is a pretty old post so you may have more workarounds coming soon, but that error is because you do not have a model config or fields config defined for your store. The model will also need to be defined dynamically if you want your grid created with json data alone.
As far as I know, the fields config is pretty forgiving, so you may be able to just set this with a maximum possible number of fields like 20 or 30 or so, but the field names would have to match with the json field names for it to be usable. I.e. if you use:
var store = new Ext.data.Store({
url: this.storeUrl,
reader: new Ext.data.JsonReader(),
fields: [
'column1',
'column2',
'column3',
'column4',
'column5',
// etc
],
Then your json data would need to come from the database like:
[{"column1":"data1", "column2":"data2", // etc
Another thing I've done in the past is to have a reference store loaded first which contained a record with the name and datatype for each of the dynamic fields (meta data). Then I iterated through this reference store and added a model field and the column definition at each iteration, then I loaded the grid's store which now had the correct data model defined and the grid would have the correct column defintion.
You may have do something like that if you don't want to make your database return generic column names as covered above, because I don't know how you will load the data into your grid store initially before you give it a data model to use.
UPDATE 13 Jun:
I haven't tried it yet, but I just came across this in the 4.1 docs (scroll down to the "Response MetaData" section in the intro). It describes using metaData in your json response to accomplish exactly what you are going for with a dynamic model and grid columns.
You would probably still have to do the iteration I described above once you process the metaData, but you can use it to cut out that additional request to get the meta data.
I suppose if your field configuration doesn't change with each request then it would be easier to simply to do the extra request at the beginning, but if you want something really dynamic this would do it.

NOTE : This is a duplicte to my response here : How do you create table columns and fields from json? (Dynamic Grid) . I just wanted address my final solution in all of the StackOverflow questions I used to solve this problem.
Stackoverflow is littered with questions very similar to this one. I worked through them all and did not find a definitive solution. However, most of the provided answers pointed me in the right direction. I'll give me best shot at putting all those suggestions together and making this clear for others:
Model: (Only shows 2 fields that will be in all JSON responses. Will still be overwritten)
Ext.define('RTS.model.TestsModel', {
extend: 'Ext.data.Model',
alias: 'model.TestsModel',
fields: [
{
name: 'poll_date'
},
{
name: 'poller'
}
]
});
Store:
Ext.define('RTS.store.TestsStore', {
extend: 'Ext.data.Store',
alias: 'store.TestsStore',
model: 'RTS.model.TestsModel',
constructor: function(cfg) {
var me = this;
cfg = cfg || {};
me.callParent([Ext.apply({
autoLoad: false,
proxy : {
type : 'ajax',
url : 'tests.php',
reader : {
type : 'json',
root : 'tests',
successProperty : 'success'
}
},
storeId: 'tests-store'
}, cfg)]);
}
});
View: (The columns will be defined in each JSON response)
Ext.define('RTS.view.TestsView', {
extend: 'Ext.grid.Panel',
alias: 'widget.TestsView',
id: 'tests-view',
title: 'Tests',
emptyText: '',
store: 'TestsStore',
initComponent: function() {
var me = this;
Ext.applyIf(me, {
viewConfig: {
},
columns: [
]
});
me.callParent(arguments);
}
});
Controller: (The controller does all the work in forcing the view and model to change based on the JSON response).
Ext.define('RTS.controller.TestsController', {
extend: 'Ext.app.Controller',
alias: 'controller.TestsController',
stores: [
'TestsStore'
],
models: [
'TestsModel'
],
views: [
'TestsView'
],
init: function(application) {
// When store changes, trigger an event on grid
// to be handled in 'this.control'.
// NOTE : Ext JS does not allow control of
// non-component events.
// Ext JS 4.2 beta will allow the controller
// to detect non-component changes and handle them
var testsStore = this.getStore('TestsStore');
testsStore.on("metachange", metaChanged, this);
function metaChanged(store, meta) {
var grid = Ext.ComponentQuery.query('TestsView')[0];
grid.fireEvent('metaChanged', store, meta);
};
this.control({
"TestsView": {
metaChanged: this.handleStoreMetaChange
}
});
},
/**
* Will update the model with the metaData and
* will reconfigure the grid to use the
* new model and columns.
*/
handleStoreMetaChange: function(store, meta) {
var testsGrids = Ext.ComponentQuery.query('TestsView')[0];
testsGrids.reconfigure(store, meta.columns);
}
});
JSON Response:
Your json response must have the "metaData" property included. It should define the fields just as you would on a static model and the view that would normally be defined to show the fields.
