I have the following commandLink

<apex:commandLink value="Save" onClick="Validation();" action="{!ActionMethod}" />

When it's clicked, I would like to stop the action from executing by returning false.

function Validation() {
        return false;
}

The above method does not work, but if I put return false directly in the onClick attribute the behaviour works as expected:

<apex:commandLink value="Save" onClick="return false;" action="{!ActionMethod}" />

Is there a way I can pass this return value up to the onClick attr?

Gist Edit

<apex:commandLink value="Save" onclick="return Validation();" action="{!saveSettings}"/>                        


function Validation() {              
  alert('returning false');   
  return false;                    
}


// Alert shows 'returning false', action still executes.

I have the following commandLink

<apex:commandLink value="Save" onClick="Validation();" action="{!ActionMethod}" />

When it's clicked, I perform some validation by checking a global var. If this is true, I would like to stop the action from executing, and if not, execute the action.

function Validation() {
 
    if (unsavedChanges == true) {
        return false;
    } else {
        return true;
    } 
}

I realise return false; will only stop the default browser action, is there a way I can block {!ActionMethod} from executing with an onClick event?

My only other option I can think of is to use an action function for the action in the conditional, but I'd like to avoid this as much as possible.
