How To Detect An Array...
Mar 17, 2003Pardon a silly question, but what's the best way to determine if a variable is an array in JavaScript? I need to treat it differently depending of if it's a string or an array.

Detect URL & Detect Something On Page & Show Content Accordingly?
Feb 14, 2009Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.
Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.
The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.
So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?

JQuery :: Submenu From Array - Function ToggleOptions Takes 3 Variables - Target - Array - State
Feb 15, 2011I am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?
Here is the code, below is my explanation:
- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.
- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.
I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target

Sorting Objects Inside Of Multidiminsional Array For Main Array?
Apr 25, 2011I am really hoping someone is willing to take the time to read this post and take a minute to take a look at my code. What is happening is there are some matches for a script I made and then an area for segments during an event. If you notice on the segment part of the form is that there is a dropdown that asks for where in the event that segment needs to go. With the Introduction or the different numbered matches. What I need to happen for a subArray I need it to take the introduction, all the matches, and all the segments and order them accordingly. With the introduction first, the matches in order based off there match number and then the segments in between the introduction or matches based off the user's input.[URL]..

Nov 3, 2010I am working on a page where the user will select a location from a dynamically generated dropdown list.

Comparing Array Values To Select Unique Array Elements?
Apr 10, 2010This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
Prototype To Sort An Associative Array On The Array Key (in Ascending Order)
Sep 1, 2010I am building a customised javascript prototype to sort an associative array on the array key (in ascending order). Basically, I am separating the array keys into a separate array and then using .sort() to sort the keys and then reassembling the original associative array elements according to the sorted keys array.
The sorting works ok except that when I run the test code below, the outputed sorted associative array has an extra element at the end of the array whose key is the name of the prototype function and the value for that element is the function code itself. Obviously I am misunderstanding something about associative arrays or how javascript prototypes work.

Take Data From An Array And Apply Each Array Item To An Element
Mar 26, 2010I'm trying to grab values from a set of arrays based on the value returned by my select box.
**Caveat - this is not an area I have any real experience with**
My arrays look like:
Code JavaScript:
I then need to test for each, then associate with one of my fees arrays, then grab each of the values in the array and write those values to elements within my page.
I'm then doing this to evaluate for each degree
Code JavaScript:
I need to first figure out how best to import all of these 60+ arrays and then in each of my conditions pull out each value and write to my page.
There is a unique 1 to 1 relationship between each degree and array so I can't consolidate as the values for each degree differ slightly.

Multiple Variables Or Array Compared To Another Array?
Mar 8, 2010how to accomplish this. In my website, I would like the user to input text into a single or multiple textbox(es) and then have the contents of the textbox(es) stored to either a variable or an array. Then I would like to have that variable/array compared to other arrays. Basically, the user is searching for items in a database. The user can search for as many or as little items as they want. Then the item(s) will be compared to multiple arrays to find out if what the user wants is in the database.
So for example, let's say the user is searching for recipes that have all or part of these ingredients: chicken, broccoli, lemon, honey. So, there would have been a total of 4 textboxes...one for each ingredient. These ingredients are stored to an array..lets call it ingredient(). In the database of recipes, each recipe has its own array which includes the ingredients needed to make the recipe, we'll call them tag1(), tag2(), and tag3(). Now, I want the array, ingredient(), to be compared to each of the "tag" arrays to see if any of the "tag" arrays include exactly match the ingredient() tag in part or in whole. Is this possible?
Display Data From One Array In Another Array Within A Table?
Nov 12, 2010I'm hoping this is possible or that there is an easier way to do this. I'm having an issue with displaying data from one array that contains information about users in a table that is controlled by a different array.Is it possible to do this or is this use of arrays to display the data the wrong approach?
The table is located on one webpage, I simply want to extract one piece of information that I have placed in the initial array as part of the login script that contains user information (for validation for login etc) and display it in a table on the new webpage that is opened as a result of successful validation of the user details. I'm completely stumped and after many attempts I just can't seem to get it to work.

Process String Formatted As Array Into Array?
Mar 18, 2011I get strings in this format:
([{"result":"-1","message":"Error","target":""},{"result":"-2","message":"Access Denied","target":""}])
this string will evaluate to a 2D array if I do this:var array = eval(string);But eval is not very safe.Is there a way to achieve the same effect (turn that string into 2d array) without using eval function?And I have no control over what string I am given, so will have to process this kind of a string =Right now I am thinking of writing a custom function which will split the string and then split again etc, but is there already something that can do this job?
