Passing a variable, and losing it in java scripting. Please help

[CFmonger]

Hello;
I am upgrading a lot of my code to cf 8, some of it was running on old code. I made a lot of serious changes and I ran into a problem in doing things this way.

Here is what I am trying to do.

I have an app that has a number of different pages doing a number of different things, adding records, inserting new ones an so on. I made 1 page called action.cfm this page has all my controls on it for all these sections of the app. To set off the appropriate code, I am using an if statement like this:

<cfif isDefined("Form.EventView_Edit")>
and it sets off the code for that form. the submit button on the form is called: EventView_Edit

Now, I am trying to pass this information through a java script I use to ask you if you really want to delete a record.

This is that script:
<script language="JavaScript">
function confirmDelete(ID_Field,ViewField1) {
if (confirm ("Are you sure you want to delete " + ViewField1 + " event?"))
{
document.HREF.action="ProjectCat-Action.cfm?id="+id;
document.HREF.submit();
}
return false;
}
</script>

This is parts of the form, passing the info.

<form action="Action.cfm" method="post">
<input type="submit" class="formButtons" name="EventView_Edit" value="Delete">
</form>

It was working fine when I had this secrions operators on it's own page, but now that I am narrowing it down with a lot of code for a number of items, it is missing the delete function because the name of the form button is not passing through the java.

How do I fix this?
Also, is there a better way of doing what I am doing? Or is this pretty much it?

Thank you.

Where you say, "This is parts of the form, passing the info", there is nothing that calls your js function.

Sorry, I forgot the hiddnen field:

<form action="Action.cfm" method="post">
<input type="hidden" name="RecordID" value="#ID_Field#">
<input type="submit" class="formButtons" name="EventView_Edit" value="Delete">
</form>

and then my java script:

<script language="JavaScript">
function confirmDelete(ID_Field,ViewField1) {
if (confirm ("Are you sure you want to delete " + ViewField1 + " event?"))
{
document.HREF.action="ProjectCat-Action.cfm?id="+id;
document.HREF.submit();
}
return false;
}
</script>

When you hit delete, it gets the java script, has all the right info, but it is not passing the name, name="EventView_Edit" of the submit button so it will activate the delete code on teh action.cfm file.

Still nothing in the code you post that calls your js function.

Sorry, forgot that part:

This is in the delete button:

onClick="return confirmDelete('ID_Field','#ViewField1#')"

<form action="Action.cfm" method="post">
<input type="hidden" name="RecordID" value="#ID_Field#">
<input type="submit" class="formButtons" name="EventView_Edit" onClick="return confirmDelete('ID_Field','#ViewField1#')" value="Delete">
</form>

Sorry. my bad

Changing a form to an href complicates things and does not seem to add any value. Something like this, http://www.shiningstar.net/articles/articles/javascript/confirmsubmit.asp, is much more straightforward.

I might just pass the delete functions off on their own page and let it work that way. I was trying to do away with a lot of pages of code, but I don't think I can with what I am trying to do.

I am reading over your link, thank you. I'll give it a try.

yes, when you submit the form via js, the submit button is not 'clicked'
and thus it is not submitted with the form.

what you need to do is create a hidden field and populate it with some
value in your js function, then check for that field and its value on
the action page.

something like this:

--the form:

<form name="myform" id="myform" ...>
<input type="hidden" name="form_action" id="form_action" value="">
...
</form>

--js:

function confirmDelete(ID_Field,ViewField1) {
if (confirm ("Are you sure you want to delete " + ViewField1 + " event?"))
{
document.myform.action="ProjectCat-Action.cfm?id="+id;
document.myform.form_action.value="EventView_Edit";
document.myform.submit();
}
return false;
}

--action page:

<cfif isDefined("Form.EventView_Edit") OR (isdefined("form.form_action")
AND form.form_action eq "EventView_Edit")>
...

That works perfectly! Thank you!

That works nice, but now I have a question, how do I catch the id that is being passed by it? I need to use this:

<cfif isDefined("URL.ID")>
This code throws an error when I add a new record.
I also tried
<cfif isDefined("URL.RecordID")>
and this doesn't work either way.

Now if there is a different variable I am grabbing from your code, this is good, because I can make a statement that shows if a record was added or if one was updated.

Is the ID different with your code? How do I grab it on another page?

Also, if it is, I want to make 2 statements, 1 for my code that works and one for the code I need to grab the id from what you wrote.
