Whats wrong with this code? i decalre resultArray as a new Array(). Then in a for loop for each resultCount i declare resultArray[resultCount] = new Array().
Then i try putting in values for every resultArray[x][y], but when i go to output the array in another function, everything in resultArray is undefined.code...
I am wondering if my code *should* work. I have a php file that reads in images from various folders. It stores the file paths in a javascript array by using echo statements. The array is also defined in the php file, as below, outside of the php tags.
var galleryarray = new Array(); for(var i=0; i < galleryarray.length; i++) {
[code]....
I am getting an error when running the HTML file that says "galleryarray[f1][f2] is undefined". I have another version of this that stores the file paths in a single-dimension array, and this works fine. I am thinking that there could be something wrong with how I am using the multidimensional array in the javascript.
I want a lookup table that matches url fragments to the name I want to show. For instance, if a url contains "yahoo.com", I want to print "Yahoo." For now, I created a multidimensional array that maps url fragments to a name. such as,
So, say I have a variable urlVar, where the value is some URL (for example,[URL]).Is there any way - other than looping through the array for every variable - to check if urlVar contains any of the substrings in urlMapping.urlPath, and if so, output urlMapping.mapto? (In this case, I want urlVar to find that it contains the substring "yahoo.com" and output "Yahoo".) In my code, I anticipate that I have 100 variables checked against 50 mappings, and performance is important to me.
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.
I'm trying to create a multidimensional array (and it's my first time using one) as an easy-to-modify way of populating content into a cycling banner script. However I seem to be having issues with actually accessing the content in the array.So currently my array looks like so:
Code:
<script type="text/javascript"> var banner = new Array(); //Option 1
[code]...
But when I do a "document.write(banner[0]['title']);" in my body, it doesn't seem to want to oblige.
I have the following (valid) json string:[code]Using firebug, I can see that the GET is returning the entire json string. However, alert only results in one of the two "text" strings being displayed ("and again"). Analyzing the watch/stack window shows that the "json" object resulting from the getJSON call has been reduced to a single "chat" element, instead of both "chat" elements present in the array.
I'm trying to use variable variable names using the window[] functionality. It works fine when you literally specify an array's base variable name, but I have a multidimensional array and would like to use window[] to build the name of the specific sub-array I'm looking for, like so:
// here's my multidimensional array myArray = new Array(); myArray['id'] = 'foo'; myArray['sub'] = new Array();
[Code]....
However if temp is the name of a sub-array (e.g. 'myArray[sub]), and not the base array name(i.e. 'myArray'), then window[temp] evaluates to "undefined".
Can the window[] functionality handle this somehow, or do I have to resort to eval() or something else?

I have an array "arr" that is an array of objects. Each object has the same 7 properties.I want to find the index of the object with a property that matches a certain value x in the array arr. The array has hash tables associated with it.
arr [ obj [ i ] . property1 + "_" + obj [ i ] . property2 ] = arr [ i ] ;
so whats the index of the object where .property1 = x ?

I'm using getJSON to retrieve information from a header record and the corresponding detail records and display the detail records in a table. The PHP script that is called returns a JSON string (via json_encode) that looks like this:
Here is the html table: <table><thead><tr> <th colspan="2" >Item Description</th> <th>Quantity</th> <th>U/M</th> <th>Item Price</th> <th>Item Amount</th> </tr></thead><tbody> <tr class="p_row_1"> .....
And here is the $.getJSON: $.getJSON("GET_INV_INFO.php",{srn:'<?php echo $srn; ?>'},function(s){ // Get Header Info $('#ip_invNo').html(s.jobNo); $('#ip_invDate').html(s.invDate); $('#ip_custNo').html(s.custNo); $('#ip_purchOrd').html(s.purchOrd); $('#ip_custName').html(s.custName); .....
My problem comes in the getJSON section where I'm trying to populate the table with a record. I don't know how to refer to the different fields in array 's'. I've tried the following and many variations, but to no avail: $('.p_row_'+i+':nth-child(1)').html(s.row.i.itemNo); $('.p_row_'+i+':nth-child(1)').html(s.row[i].itemNo); How do I refer to a nested field in a multidimensional array like this?
Using javascript, I want generate buttons and textboxes dynamically depending on selection from dropdown.Use asp.net with c# languasge.I will try using above code.But not solved the purpose
<head runat="server"> <title>Dynamically add Text Box and Button</title> <script language="javascript" type="text/javascript">
How I could dynamically generate an image via Java/Javascript.
There will be a tiny sprite-like image in the middle. What I want is to have a partial circle around the sprite appear. It will have a drop-down with 3 options, each changing the diameter of the circle. Then I want the other input box to accept numbers and that number will decide how complete the circle is, out of 360 Degrees. For instance, if someone typed in 359, then their circle would be almost complete.
I have a table with a couple random numbers, and i want to click a button that will dynamically regenerate the numbers each time the button is clicked without re-generating the entire table., im using DOM and innerhtml for these random numbers. heres the javascript and html code. so far, it just generates the random numbers when the page loads.[code]...

HTML Code:I have been trying to figure this out for awhile. I have a multidimensional array in JavaScript that is 12 columns wide and an unknown number of rows like so
<br /> /*<br />[<br /> [userID (int), name, username, email, password, other 1, other 2, other 3, other 4, other 5, other 6, admin(int)],<br />
[code]....
All the values are string except the (int) ones. This is for a real time user editing page for my site. I have the JavaScript array made now I need it so when the "Submit" button is pressed it turns the array formated like that into an PHP array and saves it as a variable.
I am implementing several scriptaculous sliders in my app... and one thing I can see being an issue is setting their "values" property to limit the selectable values.
This property takes an array of integers representing the allowable values. Unfortunately without this property, the slider will allow you to select a decimal value, so I can't just use a min and max if I only want integer values output.
Creating an array for a small data set is simple: for example "values: [0, 1, 2, 3, 4, 5]"
But some of my sliders will range into the hundreds and need an array of hundreds of allowable values. Is there a simple way to generate an array of 0 to 100 integer values (or more). I know I could use a for loop but it seems to me there might be an even easier way, though I cannot find it.
I would like it to fit in a code block like this:
javascript Code:
var s1 = new Control.Slider('handle1', 'track1', { axis:'horizontal',
[Code]....
EDIT: for further clarification, I found that PHP has a range() function that does exactly what I want. Anything comparable in Javascript? [URL]
I've never worked with Ajax before but I've been reading up on it and done some basic tutorials and am comfortable with the concept of asynchronous communication and how everything works from a technical communication perspective. That being said I have no idea where to start on this project which seems like it should be fairly simple. 1. the browser will have a "working area" which is a rectangle of some decent size, there will be a toolbar of objects on the left hand side. This work area should be shown as a grid that the objects will be placed into.The size of this grid (basically the gridlines) will need to be generated automatically based on user input (also the size of the components/objects that will be dragged in and the size of the rectangle) if it is too large (say 500) i'd like a way to pan around and zoom in as well... 2. For simplicity say there are 2 components: Available, unavailable and an erase feature. 3. each object when dragged to the working area should create an object that has some properties (handled programatically from input elsewhere on a simple form) I will be placing these in a database server side. 4. I'd like to be able to drag across the grid to continuously add the selected object and I'd like to be able to click a button on the edge of the grid to fill in the entire row with the objects. From everything I've read on this it seems like this should be somewhat easy but again I don't know what framework to use to start. I'll be putting this in a drupal site and integrating it with a few modules if that makes a difference (i think that part of the programming will be separate from whatever specific implementation I use to get this Ajax part up though)
