JSF标记上的onclick事件

Question

How to bind JavaScript onclick event to JSF-tag? Here's my JSF tag:

<h:commandLink value="Edit" action="#{adminBean.edit}">
<f:param value="#{user.login}" name="login"/>
</h:commandLink>

I've managed to bind click-event on a JSP-tag JavaScript function:

<script type="text/javascript">
function deleteUser(link)
{
    if (confirm("Are you sure?")) {
        window.location = link;
    }

    else {

    }

}
</script>

Here's my link example in JSP-tag.

out.println("<a href=\"#\" onclick=\"deleteUser('deleteUser.htm?userLogin="+user.getLogin()+"');\">Delete</a>");

How can I bind the same on-click function to given above JSF-tag ?

Answer 1

Use the onclick attribute in the <h:commandLink> tag component:

JSF code

<h:commandLink value="Edit" action="#{adminBean.edit}"
    onclick="if (!deleteUser()) return false;">
    <f:param value="#{user.login}" name="login"/>
</h:commandLink>

And change your script to

<script type="text/javascript">
    function deleteUser(link) {
        return confirm("Are you sure?");
    }
</script>

By the way, I think you have confused the terms edit and delete , but that's outside the question scope.
