Match Regex Globally Then Loop Through Result?

Mar 27, 2011

I've got the current script which returns 1 match in matches[0] with a url, but I need it to return ALL occurrences in the string.And then I need to know how to loop through the matches and display each "url" in this case.Nothing I've tried seems to find more than 1 match even when [string] contains a list of urls, which indicates I've done something wrong.

Creating Form To Submit Result Sheet Online

Jan 1, 2011

I run a website for a skittle league and am looking to create a form to allow teams to sumbit results on line. I'm not an expert on Javascript, the code I've created so far allows the user to enter the player name and score for one team and calcutate the total. However, I'm having problems duplicating this for a second team, and would like to remove the Get Total button (i.e. Auto Calculate total).

The Code I have so far is
<html>
<head>
<script type="text/javascript" language="javascript">
function getTotalH1(oForm){
var field, i = 0, total = 0, els = oForm.elements;
var fieldnames = ['PSH1' , 'PSH2' , 'PSH3' , 'PSH4' , 'PSH5'];
for (i; i < fieldnames.length; ++i){
field = els[fieldnames[i]];
if (field.value != '' && isNaN(field.value))
{
alert('Please enter a valid number here.')
field.focus();
field.select();
return ''; .....

Jul 8, 2010

Is there any function or property for finding out the size of the first (or for that matter any) dimension of a multidimensional array?EDIT:There seems to be no such functionality, I found a solution that does not require it. If anyone is reading this for the same reason; it needs to be scripted.

JQuery :: Loop Through Array And If A Match Go To Next One?

Apr 28, 2011

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.

Array Length Not Working In Safari?

Jun 8, 2009

The problem is that it keeps returning a value of 0 every loop. When tested in Internet Explorer, FireFox and Google Chrome, it works just fine, returning values as it should (in this case the values of 32, 36, 35, 36). However, like i said, Safri returns 0, 0, 0, 0.

Crazy thing is, before it calls the checkArray() function, i check to make sure its sending the correct number and it does, so its something to do with the .length part since i did a check on that and that's where its coming up with the 0's.

var aryItems = new Array();
function add2Array(theName){aryItems[aryItems.length] = theName;}
function checkArray(theName){
for ( var z=0, len = aryItems.length; z < len; ++z ){

[Code].....

Using Option.length With Php Array In Form

Feb 16, 2009

Ok the setup is basically this. The user selects a option in a drop down field, whatever they select through javscript additional records are populated in a second select field. This second select field allows for multiple selections, however I am submitting the form to a php script and I want to capture the multiple selections in the second select field. To do that for php I need to turn the field into an array so I have to add the brackets, [], to the name of the select field.

In php you can name the field like so:

Code:
<select name="fld[]" size="1">

The problem is in the js function when I give it a field name with [] the script doesnt work. Here is the js function:

Code:
function channelform(select_value) {
IntPath = document.channel_form.cid[]
TheOptions = IntPath.options.length

[Code]..

You can see the [] for the cid field name. Whenever I add that to the field name the js script is broken. How do I get it to work so that I can pass an array to php when the form submits?

Looping Through Arrays: For/in Versus Using Array Length?

Aug 3, 2009

I'm a JS beginner and I find looping through arrays with for/in is very easy. Yet I find lots of code examples where array length is used instead of for/in and I'm thinking to myself, why do it this (somewhat) hard(er) way?

Array.length Not Returning Correct Number Of Results

Nov 10, 2010

I have a function that requires the ability to count the number of entries in an array.

I'm using the following to call my function inside an input tag:

Here is the javascript:

And when errors.length is alerted, it outputs 0. I can only figure that there is an issue when using custom named keys in an array, since this works when I use only integers, however, I have the need to use a custom key index as shown.

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.
