Question

I can't find a way to on/off check box in runtime in my fieldset definition:

       {
            xtype: 'fieldset',
            title: 'Do you want to add text file?',
            itemId: 'chorFileCheck',
            checkboxToggle: true,
            items: [
                {
                    xtype: 'filefield',
                    name: 'document',
                    fieldLabel: 'File',
                    labelWidth: 50,
                    allowBlank: false,
                    anchor: '100%',
                    regex: Portal.Const.DOC_ACCEPTED,
                    buttonText: 'Choose ...'
                }
            ],
            listeners: {

I can handle this check box by hand but can't find a way to do it in my code (make it in runtime). Prompt me please how to do it.

Answer 1

You need to use collapse() and expand() methods of fieldset to uncheck & check the checkbox respectively.

For Unchecking the checkbox:

Ext.ComponentQuery.query("#chorFileCheck")[0].collapse();

For Checking the checkbox:

Ext.ComponentQuery.query("#chorFileCheck")[0].expand();
