Question

My question is more geared towards approach than it is programming or errors.

I have a query that runs and gathers a set of data. I then want to use that query’s return values to build a table on a page listing all the values. Along with that I need to have some actions with each value for example:

my_val (edit) (delete)
my_cal (edit) (delete)

Where edit and delete are buttons. So the edit button I have working with onClick javascript, where i’m redirected to another page, but the delete button i need that to do three things:

1. prompt user, okay to delete? msg (using javascript for that (return confirmation…).
2. execute query to delete
3. refresh page (self)

Is there a best approach model for this? Is it easier to call two inline javascript commands? Use javascript functions? Maybe a ColdFusion function?

any pointers would be helpful! thanks.

I think the easiest way for the delete is something like this. I do assume you use jQuery or some other library or get the JavaScript stuff.

YourPage.cfm
<cfif structKeyExists(URL, "Action") and URL.Action eq "delete">
    <cfququery>
       // delete the item using the id provided
    </cfquery>
</cfif>

<cfquery name="GetFresh">
    // get fresh info
</cfquery>

<cfloop query="GetFresh">
    Something <span class='DeleteLink' data-someid='#SomeID#'>delete</span> <br>
</cfloop>

<script type='text/javascript'>

    $DeleteLinks = $("span.DeleteLink");

    $DeleteLink.click(function() {
        var Confirm = confirm('Are you sure you want to delete?');
        if (Confirm == true) {
           var SomeID = $(this).data("someid");
           var URL = "YourPage.cfm?Action=delete&SomeID=" + SomeID;
           window.location = URL;
        }
    });
</script>
