As far as I know document.getElementById('myId') will only look for HTML elements that are already in the document. Let's say I've created a new element via JS, but that I haven't appended it yet to the document body, is there's a way I can access this element by its id like I would normally do with getElementById? var newElement = docu...
I have a multi-dimensional array, no problem. How do I interrogator one of the arrays in order to ascertain if it actually holds any data? I am working with VS 2008 and what I can see in the debugger is, lets call the element x, is x{...}. However, if I try and use x.length i get the message 'undefined' - so how do I ascertain if the ...
Now I'm sure this is super easy, I have a function called "remove_deposit" which I want it to make the checkbox false if it's true. But I can't seem to get it to work.. function remove_deposit() { if(document.getElementById('deposit').checked == true) { document.getElementById('deposit').checked == false; }; }; Am I at le...
In Python, using calendar.timegm(), I get a 10 digit result for a unix timestamp. When I put this into Javscript's setTime() function, it comes up with a date in 1970. It evidently needs a unix timestamp that is 13 digits long. How can this happen? Are they both counting from the same date? How can I use the same unix timestamp between...
I don't get what I'm doing wrong. I'm trying to populate a form from a JSON string from the server and it doesn't work. I get nothing at all back. I examine the object and it's undefined. I've been beating my head against the wall for 3 days now. I need a simple example that works and I'll build from there. Here's the simple exampl...
I am building a autocomplete feature for input text field. Currently I could use mouse click to choose the selection, I'd like to add keyboard control to allow autocomplete control. I monitored the keycode in onkeyup event, it appears for up/down key, the key codes are both 0. I am wondering whether there is any better way to do so. T...
Ok, I have this code: var room = [ { time: 0, people: 0 } ]; and then: time = 5; for( var i in room ) { if( room[i].time < time ){ spliceIndex = i + 1; } } console.log(spliceIndex); And the console reads: 01 - Which means the 1 is concatenated which further means that i is a string, and not an integer as expected. Casting t...
How can I check whether a particular element is inside an array? I don't want to manually write a loop for this; instead I want to use a JavaScript built-in function, maybe something equivalent to new Array(0,1,2,3,6,9,12,15,18).Contains(5) //return false new Array(0,1,2,3,6,9,12,15,18).Contains(1) //return true Edit the question t...
I am currently working on a web app using Wicket and started using jQuery core (UI also) in it today. I ran into an issue I troubleshooted as a jQuery function (show(), slideDown()) colliding with some of the javascript Wicket auto-generated for an external form link. Before I get deeper into this project I am wondering if anyone has ha...
I have been reading up to try to make sense of memory leaks in browsers, esp. IE. I understand that the leaks are caused by a mismatch in garbage collection algorithms between the Javascript engine and the DOM object tree, and will persist past. What I don't understand is why (according to some statements in the articles I'm reading) the...

I've got a page that retrieves a bunch of locations and some data about their associated markers and puts them on a Google Maps map. Each one is supposed to pop up its own little message when clicked on. However, clicking on ANY of them makes the most recently added message pop up at the most recently added marker. What gives?

I'm currently implementing a JavaScript library that keeps track of the history of changes to the hash part in the address bar. The idea is that you can keep a state in the hash part, and then use the back button to go back to the previous state. In most of the recent browsers, this is automatic and you only have to poll the location.ha...
