function validEmail (emailAddress)
{
for (var index=0; index < emailAddress.length; index++)
{
if ( emailAddress[index] == "#")
{
for (var count=0; count <emailAddress.length; count++)
{
if (emailAddress[count] == ".")
{
return true;
}
}
}
else
{
return false;
}
}
}
function btnParseAddress_onclick()
{
var emailAddress = addressTextbox.value;
var userName = emailUsername(emailAddress);
var domain = emailDomain (emailAddress);
var valid = validEmail (emailAddress);
if (valid)
{
outputTextbox.value = "Username:" + userName + "\nDomain:" + domain
}
else
{
outputTextbox.value = "Invalid Email Address"
}
}
Now the point of this assignment is to return a username and a domain from an inputted email address. I have deleted other functions and variables to help focus better on the problem.
I need to validate the email address first. I need to make sure there is an "#" and a "." within the string entered and return the value with true or false. True having the strings and false not having the strings. When I run the file, the return value is always false. I can't figure out if it is my for loop in the validEmail function or the if statement in btnParseAddress_onclick function
You can avoid the for loop by using IndexOf twice:
if (emailAddress.IndexOf('.', emailAddress.IndexOf('#')+1) > 0) {
Console.WriteLine("The e-mail address looks valid.");

Im trying to confirm if the password strength is strong or weak and is the password is strong and when I submit it should have alert message like "You Have Strong Password" and when its weak "Invalid Password"
This is what I am now.
function checkPasswordStrength() {
var passwordStrength = false;
var number = /([0-9])/;
var alphabets = /([a-zA-Z])/;
var special_characters = /([~,!,#,#,$,%,^,&,*,-,_,+,=,?,>,<])/;
if ($('#password').val().length < 8) {
$('#password-strength-status').removeClass();
$('#password-strength-status').addClass('weak-password');
$('#password-strength-status').html("Weak (should be atleast 8 characters.)");
} else {
if ($('#password').val().match(number) && $('#password').val().match(alphabets) && $('#password').val().match(special_characters)) {
$('#password-strength-status').removeClass();
$('#password-strength-status').addClass('strong-password');
$('#password-strength-status').html("Strong");
return passwordStrength = true;
} else {
$('#password-strength-status').removeClass();
$('#password-strength-status').addClass('medium-password');
$('#password-strength-status').html("Medium (should include alphabets, numbers and special characters.)");
}
}
}
$('#btn-submit').click(function () {
if (passwordStrength == false) {
alert("INVALID PASSWORD");
} else {
alert("You have Strong PASSWORD");
}
</script>
its for Educational Purpose only im just starting jquery..
thank you in advance..
You need to call the function instead of just checking your variable. So rather do
$('#btn-submit').click(function () {
if (checkPasswordStrength() === false) {
instead of
$('#btn-submit').click(function () {
if (passwordStrength == false) {
Then, instead of return passwordStrength = true; you should do just passwordStrength = true and add a return passwordStrength to the very end of your function so it will return either false or true.
It looks like the variable scope is incorrect. var passwordStrength should be put outside of the checkPasswordStrength function.
var passwordStrength
function checkPasswordStrength() {

I am a bit new to flash and actionscript but i am learning. With this code I am trying to get a message that says true when the value is between from and to. When I run this it gives the error in the title. What am I doing wrong?
from = Number(txtFra.text);
value = Number(txtTall.text);
to = Number(txtTil.text);
var from:Number;
var value:Number;
var value:Number;
function insideIntervall(from:int, value:int, to:int):Boolean
{
var bool:Boolean
if (from<value<to)
{
bool = true;
}
else
{
bool = false;
}
if (bool == true)
{
trace("True");
}
else
{
trace("False");
}
}
The error in the title is because your function must explicitly return a value. You do this with the keyword return.
However, there is another error in your program: you cannot compare from<value<to. What you need to check is that from < value && value < to. Basically, that both conditions are true.
The body of your function could then be simplified to: return from < value && value < to;
I would like to know how would one parse an URL.
protocol://mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes
I need to get "this_is_what_i_want/even_if_it_has_slashes"
How should I do this?
Thanks!
Try this :
var u:String = 'protocol://mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes',
a:Array = u.split('/'),
s:String = ''
for(var i=0; i<a.length; i++){
if(i > 3){
s += '/'+a[i]
}
}
trace(s) // gives : /morethings/this_is_what_i_want/even_if_it_has_slashes
Another approach would be using Regex like this:
.*?mydomain\.com[^\/]*\/[^\/]+\/[^\/]+\/([^?]*)
(Breakdown of the components.)
This looks for a pattern where it skips whatever comes before the domain name (doesn't matter if the protocol is specified or not), skips the domain name + TLD, skips any port number, and skips the first two sub path elements. It then selects whatever comes after it but skips any query strings.
Example: http://regexr.com/39r69
In your code, you could use it like this:
var url:String = "protocol://mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes";
var urlExp:RegExp = /.*?mydomain\.com[^\/]*\/[^\/]+\/[^\/]+\/([^?]*)/g;
var urlPart:Array = urlExp.exec(url);
if (urlPart.length > 1) {
trace(urlPart[1]);
// Prints "this_is_what_i_want/even_if_it_has_slashes"
} else {
// No matching part of the url found
}
As you can see on the regexr link above, this captures the part "this_is_what_i_want/even_if_it_has_slashes" for all of these variations of the url:
protocol://mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes
protocol://mydomain.com:8080/something/morethings/this_is_what_i_want/even_if_it_has_slashes
protocol://mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes.html
protocol://mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes.html?hello=world
mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes
protocol://subdomain.mydomain.com:8080/something/morethings/this_is_what_i_want/even_if_it_has_slashes
Edit: Fixed typo in regexp string
Simple way,
var file:String = 'protocol://mydomain.com/something/morethings/this_is_what_i_want/even_if_it_has_slashes';
var splitted:Array = file.split('/');
var str1:String = splitted.splice(3).join('/'); //returns 'something/morethings/this_is_what_i_want/even_if_it_has_slashes'
var str1:String = splitted.splice(5).join('/'); //returns 'this_is_what_i_want/even_if_it_has_slashes'
If you want to be a little more flexible in the feature (e.g. you need the domain), you can use my Url class.

Description
The init function checks with the regular expression if the given url starts with some letters (the protocol) followed by a colon, two slashes and more characters.
If the url contains a hash letter, everything behind its fist occurrence is taken as a bookmark
If the url contains a question mark, everything behind its fist occurrence is taken as key=value variables and parsed by the URLVariables class.
If the url contains a slash, everything behind its first occurrence is taken as the path
If the rest (everything between the last protocol slash and the first slash of the path) contains a colon, everything behind it will be converted to an integer and taken as the port. If the port is not set, a default will be set in dependency of the protocol
The rest is the domain
For answering your question, I use the path of the given url, split it by slash, cut of the 'something' and join it by slash.
I have a custom function defined that extracts part of an address from a string:
/*
* Return the number preceding 'N' in an address
* '445 N 400 E' => '445'
* '1083 E 500 N' => '500'
*/
function NorthAddress(address) {
if (!address) return null;
else {
var North = new RegExp('([0-9]+)[\\s]+N');
var match = address.match(North);
if (match && match.length >= 2) {
return match[1];
}
return null;
}
}
I want to use this function as one of the conditions in a call to FILTER(...) in the spreadsheet where I have these addresses stored:
=FILTER('Sheet 1'!A:A, NorthAddress('Sheet 1'!B:B) >= 450))
But when I call NorthAddress like this, it gets an array of all the values in column B and I can't for the life of me find any documentation as to how I need to handle that. The most obvious way (to me) doesn't seem to work: iterate over the array calling NorthAddress on each value, and return an array of the results.
What does my function need to return for FILTER to work as expected?
When a custom function is called passing a multi-cell range, it receives a matrix of values (2d array), it's doesn't matter if the range is a single column or a single row, it's always a matrix. And you should return a matrix as well.
Anyway, I would not use a custom function to this, as there is already the native spreadsheet formulas: RegexMatch, RegexExtract and RegexReplace formulas. To get the "if match" behavior, just wrap them in a IfError formula.
It doesn't work because address is, if you pass only one cell as arg a string, a range, a matrix of string.
So you return a string, FILTER use a boolean array to filter data, so the condition of your filter is string < number.
You just have to convert the string to a number when you returning a value
/*
* Return the number preceding 'N' in an address
* '445 N 400 E' => '445'
* '1083 E 500 N' => '500'
*/
function NorthAddress(address) {
if(typeof address == "string"){
if (!address) return "#N/A";
else {
var North = new RegExp('([0-9]+)[\\s]+N');
var match = address.match(North);
if (match && match.length >= 2) {
return parseInt(match[1]);
}
return "#N/A";
}
} else {
var matrix = new Array();
for(var i = 0; i<address.length; i++){
matrix[i] = new Array();
for(var j = 0; j<address[i].length; j++){
var North = new RegExp('([0-9]+)[\\s]+N');
var match = address[i][j].match(North);
if (match && match.length >= 2) {
matrix[i].push(parseInt(match[1]));
}
}
}
return matrix;
}
}
Hope this will help.
I will add this as an answer, because I found the custom function returns an error if numerical values are passed in the referenced cell or range when toString() is not invoked:
function NorthAddress(address) {
if (!address) return null;
else {
if (address.constructor == Array) {
var result = address;
}
else {
var result = [[address]];
}
var north = new RegExp('([0-9]+)[\\s]+N');
var match;
for (var i = 0; i < result.length; i++) {
for (var j = 0; j < result[0].length; j++) {
match = result[i][j].toString().match(north);
if (match && match.length >= 2) {
result[i][j] = parseInt(match[1]);
}
else {
result[i][j] = null;
}
}
}
return result;
}
}
So basically I would like to create a function that when alerted, returns the URL from an array (in this case the array is declared as 'websites'). The function has two parameters 'websites' and 'searchTerm'.
I'm struggling to make the function behave, so that when i type yahoo or google or bing in the searchTerm parameter for the function; I want it to return the corresponding URL.
Any help or support would be greatly appreciated.
Sorry if I have not made myself clear in my explanation, if this is the case, let me know and I will try and be clearer in my explanation.
Thanks in advance!
Try something more like:
var websites = {google: 'www.google.com', yahoo: 'www.yahoo.com'};
function filterURL(websites,searchTerm)
{
return websites[searchTerm] || 'www.defaultsearchwebstirehere.com';
}
** Update following comment **
Build up your websites object like so (where input is your array of key values seperated by pipe characters):
var websites = {};
for (var i = 0; i < input.length; i++) {
var siteToSearchTerm = input[i].split('|');
websites[siteToSearchTerm[1]] = siteToSearchTerm[0];
}
Here is how:
var websites = ["www.google.com|Google" , "www.yahoo.com|Yahoo" , "www.bing.com|Bing"];
function filterURL(websites,searchTerm)
{
for (var i = 0; i < websites.length; i++) {
if (websites[i].split('|')[1] === searchTerm) {
return websites[i].split('|')[0];
}
}
}
Working Example
You can also validate and improve function:
function filterURL(websites,searchTerm)
{
if (typeof websites != 'Array' || ! searchTerm) return false;
for (var i = 0; i < websites.length; i++) {
if (websites[i].split('|')[1] === searchTerm) {
return websites[i].split('|')[0];
}
}
return false;
}
Why not just use an object?
var websites = {
Google: 'www.google.com',
Yahoo: 'www.yahoo.com'
};
function filterURL(sites, searchTerm) {
if (sites[searchTerm]) {
return sites[searchTerm];
} else {
// What do you want to do when it can't be found?
}
}
alert(filterURL(websites, 'Google')); // alerts 'www.google.com'
You should really be using a hash-table like structure so that you don't have to search through the whole array every time. Something like this:
var websites = {
"Google": "www.google.com",
"Yahoo": "www.yahoo.com",
"Bing": "www.bing.com"
};
function filterURL(websites, searchTerm) {
if (websites[searchTerm] !== undefined)
return websites[searchTerm];
else
return null;
}
I'm not sure why you want to use an array for this, as what you're really doing fits a key-value pair better; however, here's how I'd do it:
function filterURL(websites, searchTerm) {
var i = 0,
parts;
for (i = 0; i < websites.length; i++) {
parts = websites[i].split("|");
if (parts[1].toLowerCase() === searchTerm) {
return parts[0];
}
}
}
But consider if you used a proper JavaScript Object instead:
var websites = {
Google: "www.google.com",
Yahoo: "www.yahoo.com",
Bing: "www.bing.com"
}
// Now it's much simpler:
function filterURL(websites, searchTerm) {
// key has first letter capitalized…
return websites[searchTerm.charAt(0).toUpperCase() + searchTerm.slice(1).toLowerCase()];
}
