JavaScript function overriding

Joomla.updatebutton is a vital javascript function within the Joomla platform. It is invoked upon submitting a form when a user clicks on either the cancel or save button. I have customized this function in the following manner:

saveFunction = Joomla.submitbutton ;
Joomla.submitbutton = function() {  
    timeValue = jQuery("div.controls > input#jform_length.inputbox").val();
    if(timeValue.length < 8){
        alert("Please enter the time in the correct format");
    }
    else {
        saveFunction('settime.save') ;
    }
}

Upon clicking the save button, 

Joomla.submitbutton('settime.save')
is executed, and when the cancel button is clicked, 
Joomla.submitbutton('settime.cancel')
is invoked. How can I differentiate whether the user has clicked on cancel or save button? In other words, how can I access the argument passed to Joomla.submitbutton when overriding the function.

Answer №1

One way to incorporate an argument into your function is shown in the example below:

if(arguments[0].toLowerCase()=='save'){

} else{

}

Answer №2

Here's a code snippet example from Joomla documentation:

var submitbuttonfn = Joomla.submitbutton;
Joomla.submitbutton = function(pressbutton) {

    console.log(pressbutton);

    if (pressbutton == 'cancel') {
        submitbuttonfn(pressbutton);
    }
    else {
        var f = document.adminForm;
        if (document.formvalidator.isValid(f)) {
            submitbuttonfn(pressbutton);
        }
        else {
            alert('Validation error');
        }
    }
}
