Does anyone have some WORKING example of a Javascript confirm when clicking on a delete button of a record?
I don't seem to be having much success with what I've found on this forum.
Here is what I've tried so far:
IN THE DELETE BUTTON "ON CLICK" EVENT:
Assuming formname is edit_usr and pagename is usermodify.php
if (document.forms["edit_usr"])
document.edit_usr.onsubmit=delconf;
function delconf() {
if (document.usermodify.FormAction.value == 'delete')
return confirm('Are you sure you want to delete this user?');
}
This does not seem to work. Any ideas where to place this confirm code or if my code would even work? This used to work in CC v2!!!

in the button's client onclick event put the following
return confirm("Delete record?");

This does not seem to work. C.C.S keeps generating this bind_events() function and it's failing in the Javascript Console!
Keep getting:
Error: document.forms.edit_usr.all has no properties
Source File: http://webdev.dal.dset.com:3000/admin/edituser.php?uid=929183352
Line: 40
Don't know why.

the script is good, I think your problem lies elsewhere. Try creating a whole new test page with script. Something is squirrely somewhere...

I agree. This shouldn't be that hard.

I have entered the following custom code associated with the DELETE button of a record in order to popup a JavaScript message before actually deleting the record (CCS automatically creates a JS variable named 'result', so all I did was to attribute my return value to this variable which is then returned):
result = confirm('Do you really want to delete this record?');
The generated code looks like below:
<script language="JavaScript">
//Begin CCS script
//Include JSFunctions @1-DA3E7A20
</script>
<script language="JavaScript" src="functions.js">
</script>
<script language="JavaScript">
//End Include JSFunctions
//page_alunos_Delete_OnClick @49-880B4AD9
function page_alunos_Delete_OnClick()
{
var result;
//End page_alunos_Delete_OnClick
//Custom Code @97-2A29BDB7
// -------------------------
result = confirm('Do you really want to delete this record?');
// -------------------------
//End Custom Code
//Close page_alunos_Delete_OnClick @49-BC33A33A
return result;
}
//End Close page_alunos_Delete_OnClick
//bind_events @1-0BF9872C
function bind_events() {
document.forms["alunos"].all["Delete"].onclick = page_alunos_Delete_OnClick;
}
//End bind_events
window.onload = bind_events; //Assign bind_events @1-19F7B649
//End CCS script
</script>
--------
1) When I get to the record page coming from a link in a grid (that is, I enter in the page to EDIT the record), the page loads fine and the JavaScript works beautifully when I click over the DELETE button.
2) On the other hand, when I get to the page to INSERT a new record, the following JS error message is popped-up by my browser (I am translating it from Portuguese):
Error in execution time. Do you want to debug it?
Line: 33
Error: 'document.forms.alunos.all.Delete' is null or is not an object
-----
Line 33 is function bind_events(). So it is not working because I enter in *insert mode* and the code CCS generates automatically always 'binds' the delete event, although I have no delete button.
Which is then the correct way to implement this simple delete confirmation JavaScript??? I used to do it with CC really easily. The code I found in this forum was a suggesttion to put the code at the form footer, but I don't see why I should not do it the 'right way', i.e., trigger the warning message after the button's 'onclick' event....
Any ideas?
TIA,
Paulo

when the form loads for an insert, the delete button is removed but the javascript to it remains, therefore throwing an error.
Solution:
put an if statement to confirm the presence of the delete button:
function bind_events() {
if (document.alunos.Delete)
document.forms["alunos"].all["Delete"].onclick = page_alunos_Delete_OnClick;

Here is the suggestion of Support (by far the best and simplest, since you do not generate useless code - I don't need this stupid 'if' condition on the first place...):
"Add the Javacript event code directly to the HTML tag for the delete button so that it is only executed when the delete button appears. If you use a client side event, the code will always fail when the record form is in insert mode."
So for example:
<!-- BEGIN Button Delete --><input class="CapuccinoButton" type="submit" value="Remove" name="Delete" onClick="return confirm('Do you really want to delete this record?');"><!-- END Button Delete -->
