I would like to set a flag using a closure so that the internal value of that closure is preserved for me to retrieve it when different events occur. It is one of those times where lack of block scope will stop me from doing what I want to do unless I can set a boolean and preserve its value in a function.
View 9 RepliesI have a webpage in which I enter a search item to look for job seekers in the Los angeles area. I get back results and now I have a column in the results table by which I can flag a certain user in my profile if I am impressed with his profile. How do i implement this ?. I know I can use the on mouse click event but how to i relate that user to the employer who logs in and how so i save that user who is flagged wrt the employer You tube uses a similar concept in which a user can flag a video if its unappropriate .... mine is a similar concept but i need to flag a user each employer login ...

Here's what I want to do:
1) I press and HOLD a key down
2) The counter goes to one
3) I let go of the key
4) The counter still reads one

I'm using the code below for the "launch page" to open a JS window and know when it has been closed, and than execute some other code that should be run after the pop-up closes.
javascript Code:
This works, and does exactly what I want. Do any of you JS experts see any reason for concern? Anything that makes it suboptimal?
I am currently strungling with the fact that I want to control the
browser closure. In fact, I have a webbased application in which I use
a wizard. Ones the wizard starts, a lock is set on specific objects in
the db. On all pages of the wizard, the user get the possibility to
exit the wizard by clicking on a custom "Exit" button. That way, I know
that the user has left the wizard and that way I can unlock the locked
objects in the db again.
So far, so good. But users are used to close browser windows by
clicking on the "X" in the titlebar. If they close a window that way,
the locks aren't unset and no other user may start the wizard again. If
I should know that he had clicked on the "X", I could unlock the
objects.
I have searched a lot on the net but all results aren't sufficient for
me.
Some solutions which don't work:
1) onunload event: =Also called when the window is refreshed or
forwarded.
2) "titlebar = no" property while opening the first page of the wizard,
is not working (the titlebar is still enabled). And even then, the
users can close the window by clicking CRL-F4. This key combination
isn't disabled by the "hotkeys = no" property.
Note: if the client's pc crashes or if the user kills the wizard
process via the task manager (exceptional cases), they have to call
maintenance to reset the locks. This is a requirement, defined by
bussiness.
In my UI framework, I have an event handler - just like many frameworks do. My handler is a static object, and contains methods to take care of things like mouse events, etc. However, upon adding a method to handle onfocus today, I ran into a very odd problem in Firefox. I've put together an example page that generates the error:

Code:
ref.a = 'abc'; console.log(inst.getZ()); //Object {a="abc"} So why does it work when you call an instance method in the constructor (e.g. this.getZ()) but doesn't work when you call the instance method in prototype?

I had a original function in this format/syntax:
Code:
GlobalFunction(){
InnerFunction(){

Other words the innerFunction behaves like it is global and has not shared variables with myClosure!

I'm using the apycom jquery menu style 1 (dim grey)URL..It's a great looking menu but does anyone know how to 'delay' the dropdown menu closure when your mouse moves off of it?I can change the speed of the menu opening and closing, but not can't find a way to delay.It's too easy for visitors to 'slip' off the menu and if you have two child menu's, it get frustraing if you drill down to the secon child menu and slip off. You have to go back to the top menu and start again.
View 2 Replies View RelatedI'm trying to group some existing top-level functions inside a closure (to avoid polluting the global namespace) but I'm not quite getting it to work. First, all the JS works outside my anonymous function, but once I put it in the anonymous function I get an error of "crossfade is not defined". I'm not quite getting why the the setInterval/crossfade works outside the anonymous function but not inside. Anything inside start() should be able to see vars/functions outside start() and it should all be protected in the closure created by the top-level anonymous function? I'm not trying to access anything *within* crossfade(), I'm just trying to execute it.
Code:
(function($) {
//vars up here that internal functions can access
//also using some jquery inside here, so using $
function crossfade() {
//body here
}
//other functions
function start() {
//body here
cInterval = setInterval('crossfade()', 5000);
}
})(jQuery);
I'd like to change the way a row looks if the row has a certain value in the results it is loaded from.I want to set the row height to be 3 times larger and set the color to be different than the color that the row is supposed to get via CSS.The table is "built" from a PHP script (also using smarty) returning data from my DB.
{foreach from=$results item=result}
<tr>
<td valign="middle" width="16">{$result[0]}</td>

I started looking at the new docs today and I'm seeing a lot of noise in the comments... people have posted comments like "thanks", "very useful", "great addition". For example, see the .toArray() page.I could add a "very useful" comment to about 50 jQuery pages -- would anyone care if I liked those? I don't think they should. , these kinds of comments are better suited to personal blogs.Is it okay to flag these comments so they get removed? or is that an improper use of flagging?
