How do I explain this? I am grabbing several elements from my document and placing them in an array, using jQuery. When I test the
Code:
typeof
this item, it returns as an Object, not an Array, which is problematic for IE. Firefox seems not to have an issue with
Code:
Object.length
, but IE won't have any of that, so I need
Code:
Array.length
or do I? In the end, I just want IE to know how many keys are in the Array/Object...
How do I convert the this object to an array.

I've been working on a function to convert nodeList and object properties to an array. The first question is with regards IE and checking whether the object provided is an HTML collection. The best I have come up with so far, is to test if it's an object, has an 'item' which is a function and has length. The second question is with regards slice.call and a while loop copy. I guess I need to do some profile/timing tests, but I'm wondering if the function merits a slice.call? or should I simplify?
Code JavaScript:
// Some weirdness in IE regarding nodesList and typeof 'item' returning 'Object'
// even though when alerted it returns 'function (){...}'.
// Therefore having to use regExp.test() to check whether it's a function instead.
// Note: _isNodeList isn't full proof. An object with the properties

I am working on a page where the user will select a location from a dynamically generated dropdown list. I was able to create the php multidimensional array (tested and working) from a MySql database using the users information at login, but I'm having problems converting it to a javascript multidimensional array. I need to be able to access variables that I can pass to a number of text fields within an html form.For instance, if a user belongs to a company with multiple addresses, I need to be able to let them select the address they need to prepopulate specific text fields.
View 9 Replies View RelatedI've been trying to create a 'loading page' for a from. When a user submitts a form, a loading animation is displayed on the page. Then I have javascript connecting to a url on my server that generates a dynamic file and returns it from memory. My problem is that I can display the text from this new file, but what I want to do is prompt the user to save the file locally. Is there a way to make this sort of conversion in javascript?

View 1 Replies View RelatedIn addition to fetching JSON you might want to POST it back to the server, but there is no postJSON method. You cannot use the generic ajax method, either. What is missing is the complement of "eval" to turn a JavaScript object in to JSON. The JSON.stringify function from www.json.org (see json2.js in JavaScript section) does the trick, but it would be nice if jQuery incorporated that out of the box, to save some hunting time.
Using the jquery ajax method to set the "type" to "json" and the "content-type" to "application/json" send and recieve JSON, but you must use JSON.stringify to convert your outgoing object to JSON. P.S.. a lot of forgiving parsers have resulted in a lot of articles on JSON being wrong. would I like to mention that here. Property names are JSON strings. JSON strings have double quotes. Therefore, property names have to be surrounded with double quotes. Single quotes are not JSON strings and not legal (JSON is not JavaScript).

I think this is a problem converting (what is assumed to be) a string to numeric. or something like that.
rvs = s[i][j] * k;
Firefox Error Console says:
Uncaught exception: TypeError: Cannot convert 's[0]' to object
rvs is just a (temporary, holding) variable.
s is a [3][6] array on numeric values.
i, j and k all happen to be zero.

I want to convert this array to JSON string and to get the JSON string back as an Array.
I'm trying to convert some Procedural code to be more Object Oriented and I'm stuck...
The page is really simple:
It's just a big picture w/ a caption under it, and a few thumbnail pics off to the side, that when clicked, replace the big picture as well as swap out the caption for a new one.
In the code (external JS file):
I've got 2 arrays:
One that holds the thumbnail image file URLs, and the other that holds the captions.
And a function:
I've created an object prototype that I can instantiate in order to:
1.) create the event: do the actual swapping of the thumbnail, and the changing of the caption.
2.) and attach that event to the thumbnail's link onclick event handler.
The code below is the closest I've come to making it work. The problem is that when I click any of the thumbnail links it only executes the last event instead of the one that corresponds to the link that was just clicked. Hopefully someone can take a look at my code and let me know what I'm doing wrong.
Simplified version of the code:
The x,y,z variable assignments are only in the window.onload function for the sake of clarity, but the event object instantiation block has to be in there for anything to work at all.
I know that the event0,event1,event2 objects work, and are attached to the onclick handler because they will swap the last thumbnail and caption when I click any of the thumbnail links. Of course that's the problem now... any click only activates the last event. It's like it attached the last event to all the onclick event handlers.
In fact, if I only create the event0 object, it works like it's supposed to... but when I create the event1 object, it does what it's supposed to and it takes over for event0. Creating event2 makes it take over for all of them. Each subsequent event# object seems to attach its own addy[ ] and caption[ ] to each previous x[ ] link.

If you've seen from my previous posts in this forum, you may have noticed that i'm a newbie when it comes to javascript, anyway. I'm trying to create an array sort of thing to convert the country name's to continent, and set it as a cookie. I spent all that time writing a PHP script for this same thing only to find out that my webhost does not have the maxmind apache module. I also don't know how to get the value of the country from a javascript function.
PHP Code:
function country_to_continent( $country ){$continent = '';if( $country== 'AF' ) $continent ='AS'; --CUT OFF DUE TO TEXT LIMIT, FIND THE FULL CODE HERE: http://infinitymedia.pastebin.com/7WWDeyVT return $continent;}
