Interesting technique!
Do you know of any best practice here?Expanding on the question, if an end user is viewing content with touch-based device, such as an iX or Android X, then hover type events (such as hover/hoverIntent, mouseover, mouseout, mouseenter, mouseleave, and perhaps other events that I haven't listed) don't make sense.Forthwith, what's the best usability practice in lieu of these events?
View 1 Replies View RelatedI have a quiz embedded on my site that originates elsewhere (QuizRevolution.com) and is embedded on my site via a link (plus some other code), part of that code being in an iframe. The quiz contains YouTube videos that, because of how the quiz is set up by QuizRevolution, will not play in browsers/devices without Flash (for example, the iPad). What I would like to do is put some script on my site that will load a SECOND quiz from QuizRevolution (this one without video) for browsers/devices without Flash. This second quiz will substitute for the first one. Does anyone know how to do this? The tricky part seems to be how I have embedded the quiz in my site, so I have included that part of the page here:

I just want to know if there is a script to display jquery when on mobile devices and flash when on computer browser?

I need to show the section inside an iframe (iFrame1) on the mainpage (mainpage.html). I am thinking of having 4 buttons, sitting on the mainpage, to help navigate between these sections on pageX, namely NEXT, PREVIOUS, TOP, END.condition of the frame, fixed width/height, no scroll, no border.Very new to javascript but need this code to make a page work for BIZ.

How would I go about controlling the parent window from the pop up, ie. changing it's content:
I tried this in in the pop up
<a href="new_page.htm" target="parent"> but that just opens up a new window.
does anybody know how I am able to control Flash Movies from html
or JavaScript? For example, I want a movie go to a specific frame
each time I open the html file where it is embedded.
I have a form frm1 . The form is generated by a "control" that is placed on
the page - I have no access to the source to modify the controls. I can
access other hidden controls within it by referencing:
ocontainer.frm1.txt1.value;
I would like to insert my own hidden control that can be posted back to to
my page so I can do something with it. How can I do this from clientside at
runtime?
Is there a possibility to compare and visualize in a user-friendly way
the differences of two html files?
I need also something like a version-control. I think I could generate
for everychange of the text a new record in the database. But now I
need a tool (JavaScript, Java, etc.) to compare and visualize two
versions of these html-files online over a web-browser.
I know, this is not really a javascript topic, but perhaps here is
anyone how knows a tool for that.
In HTML documents, named forms may be referred to as named
properties of the `` document.forms '' collection, and named form
controls may be referred to as named properties of the form's
elements collection:
var frm = document.forms["formname"];
var contrl = frm.elements["elementname"];
The (string) value property of such controls can be read
directly from the element:-
var value = contrl.value;
var value = (+contrl.value); //string to number: see 4.21
One exception is where the control is a SELECT element, and
support for older browsers, such as NN4, is required:
var value = contrl.options[contrl.selectedIndex].value;
Another exception is where several controls share the same name,
such as radio buttons. These are made available as collections
and require additional handling. For more information, see:-

How to add a new tab to a tab control by clicking a button on the first tab? Do I use the "add" method? If so how?

I have the following problem: I have a swf file that I'm inserting in my page, this swf file has a sound(mp3 imported file in the stage). I was wandering if I can stop or set the volume to 0, from JavaScript, I found that I can do(play go to frame):

View 9 Replies View RelatedI have a page with many links to media player playlists. I want to place a checkbox next to each title so that the user can check the box when they have listened to the selection.
The boxed needs to remained checked when the user comes back to the page so that they know where they left off. I also need to be able to manually uncheck the boxes.
Basically, I need to be able to check and uncheck the box at will and have it be the same when I come back to the page.
I have looked at some onclick scripts but nothing has worked yet. There may be a better way to do this that I have not thought of. Dynamic HTML, applets, etc.
I have a .net application that I am trying to add some javascript code
to for a client-side execution. What I want to do is resize all the
HTML text fields on my web form, but instead of writing a line for
each text box I would like to loop through a collection of controls
and resize the control if it is a text field. Is there a way to do
this in javascript? The function below is what I have been toying with
for the past couple of hours. Another idea was to use a css, but I
can't find an element for the text field.
function Test()
{
Tarray = new Object;
Tarray = document.Form1.children
for (var prop in Tarray)
{
//document.writeln(Tarray.toString);
var s;
s = prop
if (Left(s, 3) == "btn")
{
prop.height = "20px";
}
}
}
I have some web-server-side code that may place a textbox anywhere on a
page. It might be on the page itself, it might be within a <form>, it
might be within a <div> in the form, or in a <div> inside the first
<div>.
Is there a script out there that will let me, given just the control's
ID, recursively find it anywhere on the page so I can set focus to it?
I am having a bit of trouble with running my own (onkeyup) code in
response to a tab and then making sure that the tab-effect still occurs
i.e. focus on the next control in the tab order isn't happening even
though I return true from the function.
I need to find what control is in some position given.
I mean, if I give the values left: 200px and top 300px I need to know
what control in the page is in that position, or if there is not any.
I have been unable to reduce the size of the text that goes along with
my image slideshow(the play, next, stop buttons and also the captions
for the pictures) without reducing the size of my title text(my
friends).
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.
Is it possible to mimic the Ctrl. + Refresh functionality with a button
in a webpage using javascript, ideally by placing a button(or link) on
a page that when clicked would have the same effect as holding down the
Ctrl. key while clicking on the refresh button on the browser.
I know how to find a controls' position obviously (i.e.style left,
right, top, offset, etc.), but what I'm a little stumped on is, if
given two controls' positions, how can I tell if one is overlapping/
invading the space of the other?
For example, I have an AJAX dragpanel and am experiencing the common
'bleed through' of dropdown controls when I drag the panel over them.
Naturally the customer doesn't like this. I experimented a little with
the IFrame solution, but did not have much luck. It seems easier now
to just use the 'ondragend' event and show/hide dropdowns accordingly.
Does anyone have a piece of code where, given two control objects as
passing parameters, it returns true or false in regards to them
overlapping or not?
