Display error message using javascript alert

[r4nd7263]

I am looking for a way to display JSF error message as javascript alert.  For example say I have a AJAX-submit button , when I click on it, my server side actionListener method is invoked and adds a FacesMessage to current FacesContext, I want to create a javascript alert using the FacesMessage responsed from the server.  Is there a component or design pattern for this situation?  Any thoughts would be appreciated.  Thanks

You can store error message in your bean class any String property:

private String errorMessage = "";

Initialize "errorMessage" in your actionListener method:

........................

errorMessage = "SOME ERROR"

..........................

and set oncomplete attribute of the commandButton:

oncomplete="if (#{myBean.errorMessage != ''}) alert('#{myBean.errorMessage}')"

Hi Harut,

I use the similar alert message in my code ,

onclick="if(!confirm('Are you sure do you want to delete this #{backing_myBean.name}:  ?')){return false}"

for some names which has single quotes say backing_myBean.name=o'liver the confirm  message wont show up,

and alse onclick="if(!confirm("Are you sure do you want to delete this #{backing_myBean.name}:  ?")){return false}"(insdie the confirm i am using the " instead of ') shows error

you should escape such chars. see org.ajax4jsf.javascript.ScriptUtils class to check how we dealing with that.

Hi, try to set "'" instead of '

[ilya_shaikovsky]

try

onclick="if(!confirm("Are you sure do you want to delete this o\\'liver  ?")){return false}"

Finally worked ,

onclick="if(!confirm("Are you sure do you want to delete this o'liver  ?")){return false}"
