More compatible and more efficient, also easier to type and read:

  onclick="window.alert('Please don\'t click the "Click" button 
again')"

or

  onclick="window.alert('Please don\'t click the "Click" button 
again')"

or 

  onclick="window.alert('Please don\'t click the "Click" button 
again')"

(no line-break in-between, respectively)

This works because CDATA attribute values like that of event-handler 
attributes are parsed, e. g. for character entity references and character 
references.  That approach has the additional advantage of leaving the 
script engine less to do as it will only "see" the double-quote character as 
passed on from the user agent.

Of course, spaghetti code in attribute values should be avoided in the first 
place.

We have discussed this here before.
