So, basically, I need to detect whether an alert window was thrown. I can't find where it's thrown from but I need to disable a button only if there were no alert windows thrown.

I am trying to pop up a window and then do stuff(set flags) when the content of the new window is done loading. For this I am trying to detect the window.onload of the pop-up child window but so far I am unsuccessful. I believe my problem is that the URL of child window is on different domain, than the one of the opener(parent) so that the window.onload is not being called. Though this may change, at the moment I do not have access to the code for the page I'm opening up in the pop-up. Im pretty new to web development.

View 4 Replies View RelatedI am wondering if any of you Javascript experts can enlighten me on
which event to call. The use situation is that the tetxbox field is
populated from the DB and the add/update and delete will work only when
a textbox for reason for change is entered. This mean if a user simply
type in the same value as before, the ASP.NET textbox will be marked
with changed. But it should not limit that a user can not change the
whole value in the textbox at all.
I have looked at keyup, mousedown, etc. but it will calling the
function after every key is entered and that is what I don't want to
happen.
I am very new to javascript, it is on my list of things to learn... but I have a wide range of other traditional programming languages so I understand functions, etc
however in the mean time I am looking for a way to detect the height of a specific div.
My goal is that I have a div that is set to overflow: auto ,
If the content of the div goes beyond its set height, I would like to make a div visible. So basicly I need to get the height of a div element, and compair it to a pixel number.
To go a step beyond, it would be cool to make the div that is visible when there is scrolling, to disapear once you got to the bottom of the div.
Any ideas?

In php I would use getimagesize() and plug the dimensions into a new window but the server doesn't support it so I'm sort of stumped on how to dynamically size the windows appropriately. Any suggestions?
Is there a way to detect with javascript the height and width of a browser window that's open? Much the opposite of a pop-up where you define the height and width I guess you could say - anyone know if this is easily possible?

View 4 Replies View RelatedI know 800x600 screens occupy a shrinking part of Web surfers, but I want to accommodate them by offering an alternate style sheet where my site pages don't break when someone from this smaller group visits. Yes, there are examples of how to do this on the Web, but I have one more requirement and don't know how to code it. Not only do my pages break on 800x600, they also break if the browser widow is sized smaller on a 1024x768 screen. (I'm studying css that will dynamically respond to this but I'm not there yet.) Do I just need an appropriate if/or statement to deliver different style sheets? Is there even a JS that detects browser window changes?
View 2 Replies View RelatedI have been working on this problem all day. I have several pictures on a page. When a user clicks it, a popup window will show up a series of pictures. Inside the popup window, there is a close icon to turn of the popup. Besides, if the user clicks outside of the popup, the popup will turn off as well. Here is what I have so far.The closed icon inside the popup works fine but I can't get "the click outside of the popup" to work.

I want to detect when the window is moved, in order to trigger something. I have managed to get the current X and Y coordinates, but other than checking periodically for changed coordinates, is there a way to do this? I want to be able to trigger the code pretty instantly when the window is moved. Probably not possible without checking every half a second - this would be too cpu intensive right?

I'm wondering if it's possible to detect which of the <h1 id="i1">Item1</h1>'s that's currently shown on in the browser window?

I am building a list inside a div. When I click the list it scroll until reach the bottom.
The problem occurs when the available window height changes. I need to find a way to detect it totriggera function that re-aligns the list :)

i would like to check for the window size with jquery and based on the different resolutions i would like to change the background image. So i was thinking to somehow use the "switch" statement for more cases, but i just don't know how this would look like. This is the basic structure i want but with more options:
if ((screen.width>=1024) && (screen.height>=768)) {
//do something
}

I have a form that uses javascript for validation and cost calculating to place an order.
If someone has their javascript disabled, they will be able to submit the form, but without the cost figures showing up.
I want to prevent the user from submitting the form, but alert them that they need to enable JS to fill in/submit the form?
Is this possible? What do I need?
heres my code:
Code:
<script language="JavaScript">
var checkobj
function agreesubmit(el){[code]....
i need to make it like if the button is clicked and there the agreement checkbox is not checked.. it should give an alert that the alert is not checked.. i know that would require a if and else statement but i cant figure out how to do it
I'm relatively new to jQ and would like to determine if a named window is already open. If it is then I want to change focus to that window/tab. The scenario is this. I have a link in App1 that opens a new window to an already existing linked (related) web form in App2. If the user forgets they have that window open in App2 and clicks the same link in App1 as before (to open the related form in App2,) it opens a window that is not the same window as the original window. I need App1 to detect if a window already exists in the browser of the same name and if so, change the browser focus to it.
