Override Joomla.submitbutton = function(task) or add some task before

[ced1870]

Hi all
During my developments I have to add some interaction with the user by adding some JS elements in the page. Before saving (in a module for example) I have to clean the page and remove these elements.

I need to do some Javascript before the page is saved. The only method that I have found for now is to override the "submitbutton" function. But this is not a correct method as this function can be different in admin and front.

Is there a method to catch the submitbutton call and do some JS work before it calls the submitform function ?

Thank you

In a classic joomla submit button, just add the function you want:

<button type="submit" class="validate btn btn-primary" onclick="myfunction()"><?php echo JText::_('JSUBMIT'); ?></button>

It will execute the function "myfunction()" and then the "Joomla.submitform()".
At least, that's how it worked fr me, try it.
Let as know the result.

Thank you but this is not what I need here
The button is already generated.
Imagine that you want to add a code before the save method in a module edition, the save button is automatically rendered by the system.

I'm trying something like this that seems to work :

var Myvar = {};
Myvar.submitbutton = Joomla.submitbutton;
Joomla.submitbutton = function(task) {
... custom code here ...
Myvar.submitbutton(task);
}

If someone else have an idea :)
