Re: [jQuery] String Parsing

[jQuery] String Parsing
this might not be jquery related, but i noticed there are a lot of savvy
javascript programmers in this mailing list.
i want to grab just the filename and extension from the following string:
str1="F:\\Test1\\Test2\\Test3\\test.txt";
i want to grab "test.txt"
i use this code:
file1=(str1.split("\\"))[(str1.split("\\")).length-1];
i was wondering if there is a better way to grab that part of the string
Thx for any help

Re: [jQuery] Why I love jQuery...
ahhh.. very good
question:
i am very curious how you would:
1) append a paragraph
2) pause 3 seconds
3) and then remove the paragraph from the DOM without any effect.
all in one line of code?
