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 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.
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 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?
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 want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
I am new to learning JS and am trying to create an array through a prompt. It seems to work, but I believe it is treating the prompted numbers as strings not numbers.I am parsing the negatives and zeros, and positives and counting them. It doesn't recognize the negative sign.Here's my js:
function counter() { var numArr = new Array(Number(prompt("Please enter and array of numbers, in any order, separated by a comma..." + '[code]......
I've been wondering lately: is it possible to create an array of some html tags (let's say array of <div> or array of <p>)? Something which would allow me adding a new <div> or <p> to the array.
I am to make a small html webpage in which there are supposed to be 2 text areas: in the first are certain words (for example tomorrow, money etc.), and in the second one there is an input text (let's say "Tomorrow you must send me the money I need"). Javascript should do this: print the input text in a paragraph/div, highlighting the words mentioned above. Something like: Tomorrow you must send me the money I need. This is how I thought of the array of tags, which can at any time add a new word to the output paragraph, it's only to be chosen whether to highlight it or not.
