Using a java script comfirmation in delete record function?

Report · Jan 21, 2008

Hello;
I am trying to write a confirmation script in Java to delete a record. I don't want it to delete the whole table of information, just the record teh delete button is attached to using the ID. Here is my script, and then the code on the page:

<script language="JavaScript">
function confirmDelete(id) {
if (confirm ("Are you sure you want to delete this record?"))
{
document.HREF.action="ProjectCat-Action.cfm?id="+id;
document.HREF.submit();
}
return false;
}

</script>

Here is the query I am trying to use it with:
<cfquery name="catMan" datasource="#sitedatasource#" username="#siteUserID#" password="#sitePassword#">
SELECT Categories.Name AS ViewField1, Categories.CategoryID AS ID
FROM Categories
</cfquery>
<head>
</head>
<body>
<cfloop query="catMan" startRow="#URL.startRow#" endrow="#endRow#">
<cfoutput>
#ViewField1#
<form action="ProjectCat-Action.cfm" method="post">
<input type="hidden" name="ID" value="#ID#">
<input type="submit" name="proj_Delete" onClick="return confirmDelete('#ViewField1#')" value="Delete"></form>
</cfoutput>
</cfloop>
</body>

#Note: there is code here in my loop query for next and previous buttons, I just didn't post that code because it doesn't pertain to this question.

Is there also a way to make the Java Script state in the spot where it says, "Are you sure you want to delete this record" to make it say "Are you sure you want to delete #ViewField1#?" (the name of the record being deleted) ?

Thank you!

Since you can only submit one form at a time, it's probably simpler to put your js code right into the input tag. Here is one that I once wrote

<input
type="button"
value="Delete"
name="DeleteOneRecord" onclick="if(confirm('Delete this record?')){this.form.WhatToDo.value='DeleteOneRecord';this.form.submit()}">

when you hit the cancle button on your code, it still sends you off to the action page. Is there a way to fix that? Or make mine just say do you want to delete ViewField1? (ViewField1 should state the name of the record being deleted.

Right now, mine does delete the one record I am trying to delete and when you hit cancle, it doesn't do anything but close the script box, now i just want it to say the name of the record.

just pass 2 arguments to your js function - id AND name of category:

<input type="submit" name="proj_Delete" onClick="return
confirmDelete(#ID#,'#ViewField1#')" value="Delete">
and the function:
function confirmDelete(id,name) {
if (confirm ("Are you sure you want to delete " + name + " category?"))
{
document.HREF.action="ProjectCat-Action.cfm?id="+id;
document.HREF.submit();
}
return false;
}

but creating a separate form for each category displayed on the page is
very inefficient - you should revise your code... you do not even need a
form, really... just use <a href=...> to call your js function, or an
<input type=button ...> (without any <form ..> tags) if you absolutely
must have a button to click...
