    Answered: Sending parameter to js


    Hi,

    I have a varialble in Controller like,

    Code:
    Ext.define('MyApp.controller.MyController', {
        extend: 'Ext.app.Controller',
        onFieldButtonClick: function(button, e, options) {
        var groupChecked = Ext.getCmp('groupgrid').getSelectionModel().getSelection();
            var arrayValues = [];
            Ext.each(groupChecked, function(rec, index) {
                arrayValues.push(rec.get('colName'));
            });
        var MyGrid = Ext.ComponentQuery.query('MyGrid')[0];
                        MyGrid.getStore().reload({
                            params:{
                                singleton: true,
                                param1: [arrayValues]
                            }
                        });
    ...
    I want to use this arrayValues in another js in another location, I am doing,
    Code:
    groupField: MyApp.controller.MyController.param1
    But I am not getting the value there, how should I do to get the selected value?

  2. Hi,

    It worked like this,
    Code:
    Ext.define('MySharedData', {
        singleton: true,
    
        foo: 'bar',
        meh: 42
    });
    Can then access using MySharedData.foo, for instance.

    Found in,
    http://www.sencha.com/forum/showthre...ble-in-Extjs-4

    Didn't try it correctly initially, now works good, it doesn't do grouping like expected anyway .

    When you create your application in the Ext.application's init function do this:

    Code:
    init: function () {
        MyApp.app = this;
    }
    Then you'll have access to the application using MyApp.app. From there you can do:

    Code:
    groupField: MyApp.app.getController('MyController').param1;    // provided param1 is a property of the controller itself

    This isn't working, when I alert,

    Code:
    MyApp.app.getController('MyController').param1
    in the new file, it says "undefined" .

    If you do console.log(MyApp.app.getController('MyController')) do you see the param1 property in the list? Do you see any other properties / methods belonging to MyController?

    It just shows something like this,

    Code:
    Object { application={...},  id="MyController",  hasListeners={...},  more...}
    When I click for more info, there are lots of data, but there isn't anything related to param1 .

    Forget about parameters, I have this variable in controller,

    Code:
    var groupData = Ext.ComponentQuery.query('#groupid')[0].getValue();
    I have to have this variable in another js, groupData like that,

    Code:
    groupField: groupData
    How should I do this?

    Thanks for the reply BTW .
