Hi, I am trying to implement a mechanism where a confirmation dialogue is
raised if the user leaves a form either via the cancel button, or selecting to
navigate to another page. I only want this dialogue to appear if the model has
changed so that the user knows that they have changed the data but not saved
it. The dialogue will allow the user to select ‘yes’ to navigate to
their next page or ‘no’ to stay on the current page. Has anyone implemented something similar or have an idea how it can be
done. The idea I have had is to intercept the onChange event on all the
controls changing the forms model. This would switch the buttons to versions
which contain a SimpleAttributeModifier which adds the _javascript_ confirm
dialogue on the onClick event. This all seems very messy so any simpler
solutions would be gratefully received. Thanks in advance, Jeremy This email and any files transmitted with it are confidential, proprietary and intended solely for the individual or entity to whom they are addressed. If you have received this email in error please delete it immediately. |
