Double And Single Quotes In JS Inside HTML Attributes?

I know that using <a href="javascript:"> and <sometag onclick=""> is evil, but in this particular situation it is quite hard to avoid it due to external powers Anyway here is the issue itself : putting javascript strings inside HTML attributes :

Code:

<button onclick="DoSomething('string')">

Everything is fine until there are single or double quotes INSIDE the 'string' value. Having a double quote inside the string, even JS escaped leads to the onclick argument value being cut :

Code:

<button onclick="DoSomething('str"ing')">

If you replace the double quote by '"' then you don't get a double quote inside DoSomething (you could always replace " by " in JS).

Similar problem if you choose to enclose the onclick argument in single quotes and happen to have a single quote JS escaped inside the string.So, is there any other way of dealing with potential presence of single AND double quotes in the 'string' value, other than replacing them before by ' and " and then replacing them back inside DoSomething ?
