    Default Unanswered: Form and disabled fields: how to send their values anyway?

    Unanswered: Form and disabled fields: how to send their values anyway?


    Hi,

    I've made custom form with some fields.
    When the user checks one checkbox, some other fields are disabled.
    This is just visual, I still need to send all the values.

    The problem is that

    Code:
    form.getValues(false)
    ignores disabled fields.

    But I need to send them anyway. All my server code is based on the fact that I get all the fields. This is for homogeneous reasons (it's like that with all the other stuff with stores: I send all the fields)

    Code:
        onSave: function(){        var form = this.getForm();
            if (form.isValid()) {
                var data = form.getValues(false);
                data.id = this.idPartenaire;
                data = Ext.JSON.encode({ data: data }); 
                this.forEachField(function(){});
                Ext.Ajax.request({
                    headers: {
                        'Content-Type': 'application/json'
                    },  
                    url: '/json/gestion/item/partenaire/',
                    method : 'POST',
                    jsonData : data,
                    params : { 
                        mode: 'update'
                    },  
                    success: function(form, action) {
                        console.log('success');
                    },  
                    failure: function(form, action) {
                        switch (action.failureType) {
                            case Ext.form.action.Action.CLIENT_INVALID:
                                Ext.Msg.alert('Failure', 'blabla');
                                break;
                            case Ext.form.action.Action.CONNECT_FAILURE:
                                Ext.Msg.alert('Failure', 'Ajax failed');
                                break;
                            case Ext.form.action.Action.SERVER_INVALID:
                               Ext.Msg.alert('Failure', action.result.msg);
                       }   
                    }   
                }); 
            }   
        },
    How can I get the values even if they're disabled?

    I'm talking about a generic and proper way, because my workaround is like that:

    Code:
            if (form.isValid()) {
                var data = form.getValues(false);
                var form = this.down('form').form;
                data.livraison = (form.findField('livraison').checked ? 1 : 0);
                data.livraison_delai = form.findField('livraison_delai').value;
    
    
                data = Ext.JSON.encode({ data: data });

    what if you use readOnly instead of disabled? you can change a field to read only using the setReadOnly method:

    Code:
    field.setReadOnly(readOnly);
    where readOnly would be a boolean value to set or unset the readOnly state of the field.

    I've tried it, but is doesn't appear "grayed" and the user interaction is "broken" (= the user doesn't know he can't change it).

    And when the user clicks on the other checkbox (the one that 'grays' the other ones), there's a feeling that nothing happened, because there's visually no change (= the use may try to modify some values, and because they became readonly this won't work, which may be very confusing).

    but if this works by getting the values of those fields, then you can use it. you can change the css class of the fields to 'x-item-disabled' using addCls method (and removeCls to change it back to normal)
