ExtJS remote combo - add additional filter parameters (from other combo selection) - extjs

Question

I have 2 combos, I want to force to select the first combo (employer combo), after it's selected then the combo 2 (employee combo) is enable.
ExtJS 4.2.1
The code of the combos is:
{
xtype: 'combobox',
store: Ext.create('SoftHuman.store.catalog.Employer', {
autoLoad: true
}),
displayField: 'Description',
valueField: 'EmployerId',
fieldLabel: 'Company',
name: 'EmployerId',
queryMode: 'local',
allowBlank: true
}, {
xtype: 'combobox',
anchor: '100%',
store: Ext.create('SoftHuman.store.employee.EmployeeCombo'),
displayField: 'FullName',
valueField: 'EmployeeId',
queryMode: 'remote',
fieldLabel: 'Employee',
editable: true,
hideTrigger: true,
queryParam: 'searchStr',
name: 'EmployeeId',
allowBlank: true,
listConfig: {
loadingText: 'Searching...',
// Custom rendering template for each item
getInnerTpl: function () {
return '<b>{EmployeeNumber}</b> / {FullName}';
}
}
},
Right now my remote combo employee combo send into the query param "searchStr" that is the string typed in the combo. I need to pass also the selection from combo 1 (employer combo).
How can I achieve this? Thanks.

Answer 1

use something like this.
Ext.ComponentQuery.query('EmployerId').value
Ext.getCmp('EmployerId').value
var empValue = getComponent('EmployerId').value
if .value not work then try getValue() method.
Hope this helps.
in your second component(EmployeeId) add configuration disabled:true on load.
then add afterrender listener to the first one. and then set the other combo available.
Then do this............................................................................
{
xtype: 'combobox',
store: Ext.create('SoftHuman.store.catalog.Employer', {
autoLoad: true
}),
displayField: 'Description',
valueField: 'EmployerId',
fieldLabel: 'Company',
name: 'EmployerId',
queryMode: 'local',
allowBlank: true
listeners: { <---------------------here
select: function(combo, selection) {
if (combo.getValue() != undefined) {
Ext.ComponentQuery.query('EmployeeId').setDisabled(false)
} <----------------------------- to here
}, {
xtype: 'combobox',
anchor: '100%',
store: Ext.create('SoftHuman.store.employee.EmployeeCombo'),
displayField: 'FullName',
valueField: 'EmployeeId',
queryMode: 'remote',
fieldLabel: 'Employee',
editable: true,
disabled:true, <------------add this
hideTrigger: true,
queryParam: 'searchStr',
name: 'EmployeeId',
allowBlank: true,
listConfig: {
loadingText: 'Searching...',
// Custom rendering template for each item
getInnerTpl: function () {
return '<b>{EmployeeNumber}</b> / {FullName}';
}
}
},
Hope this helps :)
