Delete characters after the second space using jquery?

I have a list of documents that start like this...

MR 100 12.12.10
MR 100 11.12.10
MR 201 03.06.08
MR 458 04.06.09

How do I get the document names to only show MR 100 and disregard everything after the second s开发者_运维百科pace using jquery?

You can format the name using split() slice() and join():

var s = "MR 100 12.12.10".split(" ").slice(0,2).join(" ");

How you can select each document title depends on how you have your page setup.
