i hav an array named contents [i] where i wanna get every 3rd value out of it.below i make an example:
contents [i] = [2,4,6,8,10,12,14,16,18];
i wanna find a script dat could return every third value which is 3,6,9
I'm having a hard time getting my head round it again. I know it could be more efficient in jQuery, but I'd be happy just to get it working, with an extra variable, in straight js.The function takes an array and progressively hides each element at constant interval, in this case 50ms:
function hide_50(arrayA,visibility,current) {
if ( current == null ) current = 0;
var arrayB=(typeof arrayA == 'string')? arrayA.split(',') : arrayA;
[code]....
I am accepting an array, and a value of a variable to perform multiplication against my array, then write the product back into the array.
[Code]...
is it possible reference an input tag based on a variable passed to a function instead of its name directly. For instance I have a function:
function checkedAll(Name)
{
$('input.Day1').attr('checked', true);
[code]....
how to have an iframe with constant scrollbars so the scrollbars are visible even though there is nothing to scroll!
I have this now:
Code:
<script type="text/javascript">
function ChangeScrollState (select) {
var iframe = document.getElementById ("thisIframe");
[code]....
If I hit the option with scroll I get what I want, but how do I make this static?
I have a form with a textarea field. I want to validate the input from
the textarea using javascript. Suppose I want to check that the user
has not entered the string:
"Hello
World!"
To do this I am using the script:
form["text"].value == "Hello
World"
But this gives an "unterminated string constant error" because the
browser converts this to:
form["text"].value == "Hello
World"
So how do I do my check?
How is it possible to define a constant in a virtual class?
E.g. I wrote the following code
tml = {
sayHello : function()
{
alert('hello');
}}
now if I want to add a constant into tml virtual class, what I need to
do?
I tried something like
tml = {
const1 : Integer = 0,
sayHello : function()
or
tml = {
const1 : function(){return 0;},
sayHello : function()
in both case, trying to get - inside tml object - the value of
const1 ... it results in a Object value and not the Integer value I
need.
What do i need to add to the document line to stop getting an Unterminated
String Constant error?
itemtocheck = ��'
document.writeln('<!--#include

I'm getting an error message come up in IE6 when somenone subscribes to my newsletter from my home page (either from the drop down hover box form or the left hand form) here .
After entering a name and email address
I get:
A runtime error has occurred....do you wish to debug?
Line 4
Error: Unterminated string constant
When I click NO I then get a second small windows popup which says:
A runtime error has occurred....do you wish to debug?
Error: Expected ')'
I've looked at lines 4 and 43 of my thanks.php page (the page subscribers get when they fill out the form but before they double optin via the email) and I can't find anything wrong. I guess the first message expects a semicolon and the second obviously a closing bracket. Code:
I desperately need to have a constant website visitor that is online 24/7 on my website. Due to a js error. We need to keep an absolute minimum of one online site visitor. This is a temporary measure while we locate the error which so far has taken 3 js coders 3 days with no success in finding. We really need to keep the script thinking that a user is online.
Is there a bot setup that will simulate a website user that NEVER leaves a certain webpage?
If not. How can I set up the script so that I can fool it into thinking there is someone online? I really need this info... i have spent hours and another thread, with NO help on the repair. I really need to be able to keep the js rolling. I am on the verge of giving up on this project as impossible.
I am facing a problem in javascript. strdata is a variable of
javascript and following is an assignment(hmm a Huge one but
unfortunately its not mine code, I am just trying to rectify it) to
this varibale.. Now I am facing a run time error(Unterminated string
constant).....
Let's say I have a string:
div.innerHTML = "<a onclick='foo(""+myWord+"");'></a>";
in IE only (tested version 7) if var myWord = "English" then it works
fine but if var myWord = "Modifier Chau00EEnes" then I get "Unterminated
string constant" error.
What fix would you suggest to keep div.innerHTML = "" format?
make a scroller that could scroll continuously/constant both forward and backward (from left to right and right to left).
The instance shouldn't scroll unless holding down a link (arrows left&right) outside the scroller. (using onmousedown and stop onmouseup) and it would be great if it's not possible to scroll past the last and first item. (i don't want any empty space) But I guess I could do that with offset and exclude (:
I don't have any code for you, but if you want me to try some more first, I'll do that and send you if I got anything good out of it!
(I also tried the HoverScroll plugin, but since the arrows is implemented in the jquery/js-code I wasn't abled to tweak it as I wanted. That plugin is possibly the nearest already made scroller I've so far seen. However I want the buttons to be outside the scrollerarea, and I also want to be able to change the styling on the whole thing. and I want it to use onmousedown and onmouseup instead of onmouseover.)
I've tried with scrollable and ScrollTo/SerialScroll, but I'm not a code wizard so how to do this.. ;O These plugins seems really great, and I have used them in other projects, so I'm a bit familiar with how they work.
I come from a Perl background, I am wondering how I make a variable into into an array name.. example:
Code:
Perl:
$variable = 'dog';
$dog{'test'};
to make this variable into the array name I would do this:
print ${$variable}{'test'};
how do i do this same thing in javascript?
I am currently struck with getting this part working, basically, the results is a variable which has :
var results = obj.selectNodes('Search');
if(results)
{
var array = new Array(results.length);
for(i=0; i <= results.length; i++)
{
var name = getNodeName(results[i]);
array[i] = { 'name':name};
}
results = array;
}
In this , the results initially has 5 nodes and i create an array of length of results.length and assign the name . however at the end during the assignment of the array to results it stores the length as 6 where in there are only 5 nodes . the 6th one is null i.e no node exists please tell me why am i getting 6 instead of 5 nodes after going thru the for loop . before the for loop the results has the correct number of nodes as required.
How do you test a variable is an Array or not in Javascript?
Indeed, I need to get the html checkbox info in an html form like this:
<html>
<script>
function test()
[code]...
I'm trying to compare an array to a variable and see if it has the same value then output the second part of the array:
<script language="javascript">
var photoCaptionID0 = "13006";
var photoCaptionID1 = "24018";
var photoCaptionID2 = "13002";
[Code]....
So using this example. If any of the first section in the array captionID (24001, 13001, etc) has the same value as photoCaptionID0, then print the second part of captionID (Item 1, Item 2, etc).
How to convert php variable so it could be used in a javascript section.
For example I have a php array named $places, it's a nested array and I'd like to traverse through all the elements of this array much like it's done in php =>foreach($places as $place) but this done in JS.
In a nutshell how do i convert this variable into a JS appropriate variable.
If I assign an array to another variable, any changes to the array change both variables. Is it a pointer instead of a copy? Try this:
<script type="text/javascript">
Arr=['a','b','c'];
Arr2=Arr;
[code]....
Variables don't do this but it's happening for arrays in IE and FireFox, maybe all others.
I am currently trying to check using javascript whether a php array contains a variable, and if it does then display a message.I have written the following code...
<?php
//php which sets users array to the results of the sql
$selectquery = "SELECT Username FROM User";
[code].....
I need to use a javascript variable when reading a value from a asp array. Currently I have a windows app that has a webbrowser. The windows app invokes a javascript method through the webbrowser and this javascript method returns an object. This object is built in the javascript function using values which exist inside a classic asp array. The function that sits on the relevant asp page, is invoked from my windows app and then returns the object to the windows app is below.
function item(count){
var pid;
var description;
var fullprice;
var discountprice;
var quantity;
var size;
this.pid = '<%=SBagArray(0,count) %>'; //ProductId
this.description = "<%=SBagArray(1,count)%>"; //description
this.fullprice = <%=SBagArray(8,count) %>; //Fullprice
this.discountprice = <%=SBagArray(9,count) %>; //Discountprice
this.quantity = <%=SBagArray(6,count) %>; //Quantity
this.size = <%=SBagArray(2,count) %>; //Size
this.getPid = function() { return this.pid; }
this.getDescription = function() { return this.description; }
this.getFullprice = function() { return this.fullprice; }
this.getDiscountprice = function() { return this.discountprice; }
this.getQuantity = function() { return this.quantity; }
this.getSize = function() { return this.size; }
}
My problem is that the variable 'count' is not recognised by the asp. So, how can I use this variable in such a way that it works?
I want to pass array[x] to a variable so that I can use the variable in .innerHTML. I've researched and not found a reference.

I want a prompt box appear and tell the user to input a word,and have that word saved as a variable named word (for example), later I wish to run the variable through a Regex, and run an if statement in which i use the search method for the regex, if the variable is not -1 then i want to alert a specific part of an array. I probably got you going in circles, its hard to explain but basically i want to alert an array named whatever the user inputs, as long as i have the users input already made: for example: the user inputs a word and saves it as a variable named word, then i want to call an array that is the same as the users input.
example:
if he inputs hello,
i want to call for example the array hello[2]
if he inputs internet
i want to call the array internet[1]
$i=0;
echo '<script language="javascript">
var dA = new Array();[code]...
here i want to increment $i above code is not working,
I was wondering if it is possible to put all the non null variables of an array into a string variable with spaces between each array value? For example, if array() is a text array and has 10 values, array(0) through array(9), with three of those values null, let's say array(3), array(5), and array(7) are null, is there a way to put the remaining seven values into a string variable with spaces between each array value?
