Regalur Expressions - Operator On Words And Phrases Without Adding Terms To The Match Array?
Feb 3, 2011
I have a set of regular expressions that make heavy use of the | operator on sections that I do not really need to extract a match from. For example:
Code:
var regexp = /([A-Z][A-Za-z]+) (jumps( high)?|leaps|bounds) over ([A-Z][A-Za-z]+) and (grabs|snags|gets) (a|an|the) (apple|orange|pear|grapes)/
The important part for extracting from the match array after using regexp.exec() are the names (the ([A-Z][A-Za-z]+) parts), I don't care which of the other things are matched. The problem is that using the | operator seems to necessitate using the () and adding a term to the match. This makes it difficult to know which term in the array will be the names, especially after editing the middle.So I'd like to be able to use the | operator on words and phrases without adding terms to the match array.

I am trying to match an email string that ends exactly with ".com". Here's what I have
var email = window.prompt("Enter your email", "");
var email_match = /[a-zA-Z1-9-_.]{3,}@[a-zA-Z]{3,}.(com)/
if (email_match.test(email))
[code]....
the (com) also matches commm for some odd reason. What must I change in the code so that only emails ending with .com is valid?

anotherVar should be -1 if there are no matches, but it doesn't seem to work var string = "abadafa"; var matches = string.match(/a/gi); //doesn't work with /z/ for example
var anotherVar = matches.length || -1; The default operator should return the second value if the first is null or false, and according to try { alert(matches.length);
}
catch (e){
alert(e); //alerts null
} it's null.

var toSearch = "I Wish This Worked. What Is The Issue?";
var pattern = /is/gi;
result = pattern.exec(toSearch);
alert(result.length); Shouldn't this be 4, not 1?
/*while((result = pattern.exec(toSearch)) != null)
alert(result[0] );*/
The commented out code works to access all instances of 'is'. But what's the point of returning an array if you're only going to use one index(0)? You'd have to manually code to get a full array of the returns, doesn't that defeat the purpose?

I am learning Javascript from this book I got, and I am trying to do one of the "challenges" in the Hangman example, and that is to add on more 8 letter words to it and have it select by random. I am assuming that it's asking me to do this with arrays, but I have no idea how to implement that on this while having it select randomly.

I am coding a random name generator in javascript and at the moment I have the first names and last names in two seperate arrays. I'm adding more names into the javascript itself and it gets messy after a while. When the list is populated to hundreds of names it's gonna be tough keeping track of things.
I was wondering how to have the names listed line-by-line in two text files (first name, surname) and to call the files when the user clicks the generate name button.

How would one search for more than one one simultaneously? I have this function:
var flix = ["Any items left unattended on this table" , "Hello, World"];
function Multiwords(s){
var a = flix[0].toLowerCase();
var b = s.toLowerCase();
var result = a.indexOf(b)
if (result >= 0)
[Code]...
It's pretty basic, it just searches through the first index of var flix and tells me if the parameter (s) is 'found' or 'not found'. I made it not to be case sensitive. However, how would I search for multiple words for example:
Multiwords("ANY items This") and if any combination of 'ANY' or 'items' or 'This' is found, i still get my alert message of 'Found'?

I know that others have asked about adding a class to a navigation based on indow.location, but I couldn't quite fit my question within those bounds, so hopefully it's alright to ask here.RequirementAdd a class based on window locationComplexityThe current if/else method I have doesn't work correctly, because all subsequent URLs will have the initial word we're looking for,andI'd like to have the final else to be on nav id#3 - (because the url's there will all be varied and may change later so adding those specifically in the if/else seems redundant)So far I've probably explained nothing, so here's what the code looks like:
if (window.location.pathname.match(/(employees)/)) {
$('#nav1').addClass("selected");
}

I am trying to get good using the $.each() in jQuery. I have a simple little task that I want to solve.
I have created a simple page with 100 boxes, each box with 4 colors. What I want to happen is if you click one box, it will change colors to the next box and so on. so for example here are 4 boxes
Red | Green | Blue | Yellow
If you click on Red you would get:
Green | Green | Blue | Yellow
If you click on the Green (1st one) you would get:
Blue | Green | Blue | Yellow
I have created a jsfiddle for you to view with what I have so far. I am stumpped at creating a match for the class name and if it matches to then go onto the next color in the array.

why I get an array containing [xml, xml]
Code:
str = 'index.xml'
re = RegExp( /([^s./]+)$/ ) ;
str.match(re) // -> [xml, xml]
I only need xml, not an array, and especially not [xml, xml]
Update: thnx mrhoo, thats clear now!

What I am trying to do is build a script that will read through an array of words and compare another word to the list to find where it would be placed alphabetically; between which two words would my word go.
Here is what I have come up with so far which doesn't work with words shorter than the shortest word in my list, or words spelled like the shortest word in my list except having a few more characters, plus more various issues.
Example: My list
If I use keywords "apex," or "as", this script fails.
What can I do to fix my code...

I have an FAQ page on my site, but, because much of the information could be
relative to the area council's bylaws, I want to have a pop-up window appear
when someone clicks the "FAQ's" menu button. In the window will be my
disclaimer regarding the use of the information on the FAQ's page, and then
I want them to click either "I agree" (action will close pop-up and direct
them to FAQ's page) or "I disagree" (action will close pop-up and leave them
at page they were at when clicking the link).
The script needs to be linked to the clicking of an image.
