[JS - CS3] Can't REPLACE A with B within a string? Help Please...

Question

Hello Experts,
First off - I'm a newbee to all this JS and especially with CS3.
I have a string: '
b myDocumentName
which can have it's value as: '
b 00000en_ Generator WX/WY
Problem is, backshlashes ( / )are a bad thing for me...
b Question:
How can I do a 'replace' operation to replace the '/' from the string with a '_'?
I have at the moment:
> var myDocSaveName = oneResult[3]+oneResult[4]+oneResult[5];
> myDocSaveName.replace(what "/", with "");
> myDoc.save ("C:/DATA/"+myDocSaveName, undefined, undefined, true)
I get an error Nr. 25... Offending text:"/"
What am I doing wrong?

'what' and 'with' are the names of those arguments. They should not be included in the statement:
myDocSaveName.replace("/", "");
But that still won't work because replace doesn't operate on a string in situ, it returns the modified string. So:
myDocSaveName = myDocSaveName.replace("/", "");
This too has its limitations. It'll change only the first instance of "/", not all of them. To change all of them, you need to restate the 'what' as a RegExp:
myDocSaveName = myDocSaveName.replace(/\//g, "_");
A RegExp literal is delimited by the "/" character, so to have it, alone, as the character to be sought you must use the backslash to escape the character. Then, to indicate you want the replace to happen globally within the string, you add the 'g' after the RegExp.
