Javascript / Client Side Development :: what is the reg exp to do this?


	what is the reg exp to do this? Hi, I want to create a regular expression that will take a single input name field and save the first and last names to two separate js vars. The criteria for determining what is the separation would be the first occurrence of a space (ascii code = 32). However, note that a user may only enter one word or nothing at all. If the DOM id for the field I want to parse is "nameField", how would I do this? Thanks, - Dave laredotorn@zipmail.com said the following on 5/23/2007 5:03 PM: > Hi, > I want to create a regular expression that will take a single input > name field and save the first and last names to two separate js vars. > The criteria for determining what is the separation would be the first > occurrence of a space (ascii code = 32).

Why are you making it harder than it has to be? var theNames = refToFormElement.split(' '); If theNames has a length of 1, then there was no space. If theNames has a length of 2, then there was a space. If theNames has a length > 2, then there was more than one space. -- Randy Chance Favors The Prepared Mind comp.lang.javascript FAQ - http://jibbering.com/faq/index.html Javascript Best Practices - http://www.JavascriptToolbox.com/bestpractices/ On May 23, 3:03 pm, "laredotorn@zipmail.com" <laredotorn@zipmail.com> wrote: > Hi, > I want to create a regular expression that will take a single input > name field and save the first and last names to two separate js vars. > The criteria for determining what is the separation would be the first > occurrence of a space (ascii code = 32).
