The wicket phonebook has
an example on howto do this or at least something similar.. From:
[EMAIL PROTECTED]
[mailto:[EMAIL PROTECTED] On Behalf Of Macrae, Jeremy 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. |
