how to conform deleting in jsf
I am pretty new to jsf.
I am using commandLink and doing deleting from database.But before deleting I want to let user conform his/her behaviour. I don't want to create another form and bean for this. So I use java scirpt here.
I post relevant code:
<SCRIPT LANGUAGE=JAVASCRIPT>
function verify(){
msg = "Are you absolutely sure that you want to submit this form?";
//all we have to do is return the return value of the confirm() method
return confirm(msg);
}
</SCRIPT>
......
<h:commandLink actionListener="{ViewUicLookupBean.uicLookupDeleted}" immediate="false" value="Delete" onmouseup=verify() >
<f:param name="uicLookupId" value="#{currentRow.uic}"/>
</h:commandLink>
.....
I test my program. When I don't add "onmouseup=verify()" in commandLink it works fine. But after adding it displays the conform dialog firstly and in this dialog if you select "OK" it don't delete record.
Anyone know sth about it?

You can try use the example to add confirm prompt to wrap around the original onclick functon.
<html>
<head>
<script>
function addConfirmPrompt(c,msg){
var tempFunc = c.onclick;
var newFunc = function(){ if(confirm(msg)) return tempFunc(); }
c.onclick = newFunc;
}
function init(){
addConfirmPrompt(document.getElementById('c'),'Are you sure you want to delete this item?');
}
</script>
<head>
<body onload="init();">
<a id="c" href="#" onclick="alert('ok1'); alert('ok2');">click here</a>
</body>
</html>
normally, when you use javascript to validate a click, you'd have script that looks something like:
<a href="#" onclick="return confirm('are you sure?');">delete</a>
But, since that will stop the execution of any javascript that occurs after the ; and the JSF commandLink button adds the javascript necessary for submission after, you need to only return if the outcome is false. What I've gotten to work is this:
onclick="if(!confirm('are you sure?')){ return; }"
It's a little ugly, and a little verbose. But it shoud work.
