I have created an onclick event on the cancel button in my visualforce page and it works as expected. I want to change the wording for OK and Cancel button to Yes, Proceed and No, Stay.
Is it possible. if yes, can someone suggest me how or share sample code
 

<apex:commandButton value="{!$Label.Cancel}" action="{!Cancel}" onclick="return confirm('{!$Label.Proceed_with_Cancellation}');" styleclass="slds-button slds-button_brand" style="width:150px;"/>

 

Error: Method does not exist or incorrect signature: void replace(String, Datetime) from the type String

also, i noticed that even when i comment out the this line of code it is still returning the same error. please suggest.
