Hello NetDs,
The following is what Janet has achieved for ND 3. (Pls. see code at the
end)
I am now trying to do the same in ND4. There seem to
a problem especially on:
document.pgXXX.action =
"../PrXYZ/pgXXX.onLoadTasksWebEvent(LoadTasks)";
part of this solution.
here is what i am doing in JS:
document.pagAccts.action =
"../NewsWeb/pagAccts.btnRefresh_onWebEvent(btnRefresh)";
document.pagAccts.submit();
........
.......
& here is the commented button within the page's HTML:
<INPUT TYPE=SUBMIT NAME="btnRefresh_onWebEvent(btnRefresh)"
VALUE="Refresh" >
The page goes thru a normal reload rather than, the web event of
invisible button. The action value set is not recognised by ND.
Thanks in advance for any help.
regards,
Raj
Javascript: trigger event for invisible button -
SOLUTION (in ND3)

Thanks for the replies Sridhar, Grace and Brendan.
Here's some details on how we solved it.
NOTE: This is an ND3 app.
1. comment out the button to hide it:
<!-- **btnLoadTasks** This is commented because it is
called via
Javascript: chgProjWP() -->
2. alter the default HTML for the comboBox to also
contain:
OnChange=chgProjWP()
3. in the Javascript function being called by the onChange
event, instead
of just doing this:
function chgProjWP()
{
...
document.pgXXX.elements["onLoadTasksWebEvent(LoadTasks)"].click();
}
we replaced that line with Brendan's tip about setting
"action" for the
form and then calling submit on the form:
function chgProjWP()
{
....
document.pgXXX.action =
"../PrXYZ/pgXXX.onLoadTasksWebEvent(LoadTasks)";
document.pgXXX.submit();
}
It works and we're happy and grateful! If anyone sees
something we could
have done better, let me know.

Janet,
I would like invisible the image button approach if
JavaScript worked with
images.
Given that it does not, my favorite option is to comment
out the button
**btName** tag in the HTML file and add the explanation
that the event is
triggered with JavaScript. This is the same as set
visible(false).
In the JavaScript on change handler for the drop down you
will need add the
buttons name value pair to the action field of the form
tag then call
submit
on the form object.

Two possiblities:
1. Create a 1px x 1 px image button where the image
is transparent.
2. Rather than calling
../projName/pgName.btn_onWebEvent, call
../projName/pgName
This will cause the page to be loaded (as it would if
you just
requested the
page directly). I'm not sure if that will work, but
it's worth a
shot.
