Using Ext Js 4.1.
I have multiple checkboxes in panel with ids and itemIds: 'chA104', 'chA204', 'chB111' etc.
And I want to get all checkboxes that starts with id (or itemId) = 'chA' to make them disabled.
How to do that?
Tryed to use this:
this.query('*[id^=chA]');
But get an array with multiple elements: table, td, input etc.
When doing this:
Ext.query('input[id^=chA]')[0]
I get an html input element. But when trying to do:
Ext.query('input[id^=chA]')[0].disable();
Ext.query('input[id^=chA]')[0].setDisabled(true);
I get an error.
So how to get all checkboxes, starting with a string id (or itemId) and make them enabled/disabled?
If you are using extjs checkboxes, you could do it like this:
//enable/disable
Ext.ComponentQuery.query('checkboxfield{id.search("chA")!=-1}')[0].disable();
//check/uncheck
Ext.ComponentQuery.query('checkboxfield{id.search("chA")!=-1}')[0].setValue(true);
if is pure html just use:
//enable/disable
Ext.query('input[id^=chA]')[0].disabled = true;
//check/Uncheck
Ext.query('input[id^=chA]')[0].checked = true;

I'm currently working on a springboot/reactjs project. I'm using the react select library to set a multi select input in one of my forms but I could not get the selected values here's some code to make it a bit clearer.
these are my options generated dynamically from the database each option has the webService Id as a value
this is my select input, I need to get the selected values "Ids" and then call the method that retrieves the webservices from the database and then assign the list of webServices to my newApplicationData.webservices
this is the get web service function
Update : I kind off found a solution to my problem : on the onChange prop I used this
onChange={(selectedOptions) => {
const state = this.state;
state.selectedWebServices = [];
selectedOptions.forEach((option) => {
this.getWS(option.value);
state.selectedWebServices.push(this.state.getWSData);
});
state.newApplicationData.webServices =
state.selectedWebServices;
this.setState(state);
}}
and then I found out another problem: even if I select two deffrent options the list of selected options only gets one duplicated option????!!!!
Just started using ATK4 and appreciating it very much so far, but not sure how to do this...
What I am trying to accomplish:
I am outputting a query's results to a grid, one of the fields is 'status', the data will either be '-1' or '1'.
Instead of outputting -1 or 1 to the column, how do I output an HTML snippet (or whatever I need to to get what I want) instead that shows a different icon for each value?
In short:
In column 'status':
if the value is -1, display iconDown.gif;
if the value is 1, display iconUp.gif
Code so far:
class page_showlist extends Page {
function init(){
parent::init();
$q=$this->api->db->dsql();
$q->table('remote_system')
->join('customers.id','customer_id')
->field('customer_id')
->field('ip')
->field('nickname')
->field('name','customers')
->field('status')
;
$grid = $this->add('Grid');
$grid->addColumn('text','status')->makeSortable();
$grid->addColumn('text','name')->makeSortable();
$grid->addColumn('text','ip');
$grid->addColumn('text','nickname');
$grid->addButton('Reload Grid')->js('click',$grid->js()->reload());
$grid->addQuickSearch(array('name'));
$grid->setSource( $q );
}
}
Any pointers/tips?
To add column with icons in Grid you can use custom template.
In one of my projects I do like this:
$url = $this->api->pm->base_url . $this->api->locateURL('template', 'images/');
$grid->addColumn('template', 'type', false)
->setTemplate('<img src="' . $url . 'icon_object_<?$type?>.png">');
It'll use model field named type (in your case use status) and show icons in that column. Icon source URL is generated dynamically and it'll search for image files in your template/images directory named icon_object_XXX.png where XXX value will be taken from field type value.
In my case type is like this: array('building','apartment','land','garage') etc.
And one more thing - you should start using Models whenever possible! That way you'll ease your life later when your project becomes bigger. Also can have extra security (conditions, etc.) with them.
I have a multiselect grid where I can get schools.getSelectionModel().getSelection();
there is an object called data, I want to get a field within the data; lets say school_name
How I'll do it?
I've tried
schools.getSelectionModel().getSelection().data
schools.getSelectionModel().getSelection(data)
schools.datagetSelectionModel().getSelection()
they did not work.
You have to use Ext.each to iterate over the array of records..
Ext.each(schools.getSelectionModel().getSelection(), function(record, index, allRecords) {
console.log(record.get('school_name');
});
This:
schools.getSelectionModel().getSelection()[0].get('school_name')
should give you a 'school_name' field from first row selected (which is also a first record in selection).
To iterate over all selected rows do:
var selectedSchools = schools.getSelectionModel().getSelection();
for (i in selectedSchools) {
console.log(schools[i].get('school_name')); //this will log school name to firebug console - you can do whatever you need
}
When adding a rows to a grid, and then clicking on it, it gets selected (and highlighted). Then, clicking elsewhere but the new row remains highlighted (so now there are to highlighted rows).
Please, does anyone know what the problem could be? How to make it behave normally, i.e. clicking a row deselects (de-highlights) the other one?
After I reload the page (so the new row is not new anymore), everything works as expected.
Edit: Here's the code for adding rows:
var rec = new store.recordType({
test: 'test'
});
store.add(rec);
Edit 2: The problem seems to be listful: true. If false, it works! But I need it to be true so I'm looking at this further... It looks like as if the IDs went somehow wrong... If the ID would change (I first create the record and then the server returns proper ID, that would also confuse the row selector, no?)
(Note, correct as ExtJS 3.3.1)
First of all, this is my quick and dirty hack. Coincidentally I have my CheckboxSelectionModel extended in my system:-
Kore.ux.grid.CheckboxSelectionModel = Ext.extend(Ext.grid.CheckboxSelectionModel, {
clearSelections : function(fast){
if(this.isLocked()){
return;
}
if(fast !== true){
var ds = this.grid.store,
s = this.selections;
s.each(function(r){
//Hack, ds.indexOfId(r.id) is not correct.
//Inherited problem from Store.reader.realize function
this.deselectRow(ds.indexOf(r));
//this.deselectRow(ds.indexOfId(r.id));
}, this);
s.clear();
}else{
this.selections.clear();
}
this.last = false;
}
});
And this is the place where the clearSelections fails. They try to deselect rows by using ds.indexOfId(r.id) and it will returns -1 because we do not have the index defined remapped.
And this is why we can't find the id:-
http://imageshack.us/photo/my-images/864/ssstore.gif/
Note that the first item in the image is not properly "remapped". This is because we have a problem in the "reMap" function in our Ext.data.Store, read as follow:-
// remap record ids in MixedCollection after records have been realized. #see Store#onCreateRecords, #see DataReader#realize
reMap : function(record) {
if (Ext.isArray(record)) {
for (var i = 0, len = record.length; i < len; i++) {
this.reMap(record[i]);
}
} else {
delete this.data.map[record._phid];
this.data.map[record.id] = record;
var index = this.data.keys.indexOf(record._phid);
this.data.keys.splice(index, 1, record.id);
delete record._phid;
}
}
Apparently, this method fails to get fired (or buggy). Traced further up, this method is called by Ext.data.Store.onCreateRecords
....
this.reader.realize(rs, data);
this.reMap(rs);
....
It does look fine on the first look, but when I trace rs and data, these data magically set to undefined after this.reader.realize function, and hence reMap could not map the phantom record back to the normal record.
I don't know what is wrong with this function, and I don't know how should I overwrite this function in my JsonReader. If any of you happen to be free, do help us trace up further for the culprit that causes this problem

Looks like to have multi select enabled for you grid. You can configure the selection model of the grid by using the Ext.grid.RowSelectionModel.
Set your selection model to single select by configuring the sm (selection model) in grid panel as show below:
sm: new Ext.grid.RowSelectionModel({singleSelect:true})
Update:
Try reloading the grid using the load method or loadData method of the grid's store. Are you updating the grid on the client side? then maybe you can use loadData method. If you are using to get data from remote.. you can use load method. I use load method to update my grid with new records (after some user actions like add,refresh etc). Or you could simply reload as follows:
grid.getStore().reload();
Got an issue, and need your advices
I just started writing an editor grid. (I will actually use this grid as a search filter editor, i.e. columns with criteria name, operators and values).
Now, for the value field, I want to have different edit controls for different rows. For instance, when a criteria type is string I want to display a text box, when it's date time, I want a datetime editor.
So the fact is, I need to control the "edit control creation/display" just before editing starts. and it should be different among rows. Unlike the examples I found which are fixed for the columns.
In order to implement this, can you guys please suggest the steps I need to do? I can probably figure out it if one of you can direct me a way.
Thanks and best regards
Actually you can easily accomplish this by dynamically returning different editors and renders depending on the column you're in. In your ColumnModel object you can define something like this below. Note that i'm getting a type property of each record to determine its type. I have an object containing all my different types of editors, and the same for renderers, and then based on the the type i dish out a different editor or renderer for that cell.
editors: { 'default': {xtype:'textfield'},
texttype: {xtype:'textfield'},
numbertype: {xtype:'numberfield'},
combotype: {xtype:'combo'}....... etc. }
getCellEditor: function(colIndex, rowIndex) {
var store = Ext.getCmp('mygrid').getStore();
var field = this.getDataIndex(colIndex);
var rec = store.getAt(rowIndex);
var type = rec.get('type');
if (type in this.editors) {
return this.editors[type];
} else {
return this.editors['default'];
}
},
In the configuration section of your editorgrid, you will need to define your custom editors:
{
xtype: 'editorgrid',
id : 'mygridID',
stripeRows: true,
...
...
,customEditors : {
//configs go here or pre-define the configs prior to this
'columnName1' : new Ext.grid.GridEditor(new Ext.form.Combobox(configObject)),
//configs go here or pre-define the configs prior to this
'columnName7' : new Ext.grid.GridEditor(new Ext.form.CheckBox(configObject))
}
}
use this grid config - in order to select whole rows:
selType: 'rowmodel'
