Get Real Image Dimension With Script?

Jul 15, 2010

How can I get the real image dimension with javascript? code...

However this only seems to be working sometimes in Opera . No luck in firefox or chrome (dunno about IE)

Anyways to do it?

I thought of maybe using an Ajax call, but then the imgLink cannot be a relative position, which would be difficult to parse due to some address like http://example.com/directory as i tried to get everything before the last /

How To Resize / Reset Dimension Of Image To Fit In DIV

Oct 19, 2010

I've written some javasript code to resize an image tag. While the page loads the image tag is display: none so a large image wont break the stylesheet before I have a chance to shrink it. onload I call function load1 and you can follow the rest from the code below. This is working in Firefox and Chrome and appears to be doing absolutely nothing in any version of IE.

Javascript after </html> tag:
<script type="text/Javascript">
function load1() {
imageLoaded();
document.getElementById("confImage").style.display = "block";
} function imageLoaded() {
var iW = document.getElementById("confImage").width;
var iH = document.getElementById("confImage").height;
changeImageSize(iW, iH);
} function changeImageSize(iW, iH) {
if (iW > 460 || iH > 460) {
reset dimension of image to fit in div
var multiply = 0;
if (460 / iW < 460 / iH) {
multiply = myFloor(460 / iW, 3);
} else {
multiply = myFloor(460 / iH, 3);
}
document.getElementById("confImage").width = multiply * iW;
document.getElementById("confImage").height = multiply * iH;
}}
function myFloor(n, pos) {
n = "" + n;
if (n.length < n.indexOf('.') + pos + 1) {
return parseInt(n);
} else {
return n.substr(0, n.indexOf('.') + pos);
}}
</script>

Getting Window Dimension With Onresize

Apr 10, 2009

I want to make a nice floating bar at the bottom of the screen, which hovers about 15px from the bottom. I am doing this to make a site look good in small and big resolutions. The minimum height for the bar to hover is 600px about, if the window is smaller, it is still there so it doesn't go into the content, if the window is bigger, it will follow the resize and be at the bottom still. It is obviously absolutely positioned, and also centered using some javascript (getting the width of the window).The second function is called in the header and positions the bar. The last two document.get things are just for testing so I can see the height in px somewhere. This works fine in IE. If I resize the window, making it shorter, everything goes as planned, and I can see the pixel count dropping in the header where it is displayed. However, in FF it does not work.

The weird thing is this. If I resize by a small amount, less than 10px, it works fine. However, I can not resize by more than 10px! If I do, the window height shown in the top still drops by only 10px.So if my window is 1000px tall, and I close it to say 500px, the value of the height will still be 990px. If I then resize it to any where higher than the 500px, say 550px, the javascript still sees it as making it smaller, since it says the height is 990px, therefore, the window height goes down to 980px. If I shrink the window to 500px and reload everything is fine, if I make it bigger, it works in both browsers. I am thinking that this could be a problem which is like "sampling rate" in music. When in IE I expand or shrink the window I can see the pixel count drop continuously and the bar floating down as I move the window, as if it was "sampled" every 0.05 seconds or something. In FF, shrinking is not working, but if I expand the window the pixel count doesn't change and the bar doesn't change place until I stop resizing (let go of the mouse button), as if it was sampled once, when I stop, so the problem maybe is related?

Real Text Size Calculation?

Jul 20, 2005

I've got a small problem here. I'm trying to write some code that would
generate a drop-down menue for me, where I'd just need to enter the
menu- and submenu items into an array. The items are to be displayed as
text. Now, I want to have the layers with the submenues to appear more
or less under the appropriate main menu items. For this I need to be
able to calculate how many pixels a given text uses up on the screen of
the user. That's all fine with IE and an unproportional font like
courier. The problem is, there is this nice setting that allows you to
change the diplay size of the text - which is pretty much disfunctional
in IE, but in mozilla, it works. Which means that I can't just say that
one letter in courier, size 2, is 4 pixels wide and be happy with my
calculation, because then somebody can just pop up with another text
diplay size and *boom* - my calculation is wrong again.

Now, is there a realistic way to find out how many pixels _exactly_ a
piece of text takes up on the user's screen? Or can I make the given
piece of text a DIV and then have some kind of document.divname.left
that gives me the actual location of this text?

How Can I Update A Form In Real-time?

Jan 31, 2007

I'm making a survey where every question has a numeric value assigned to it, and as the user clicks on a checkmark button to approve (or uncheck to disapprove) the values add or subtract to give a total at the bottom of the page.

Basically, it's a spreadsheet but with fixed values for each row instead of being able to type them in.

I can do this easily with php, but only if the user clicks the submit button. I was hoping to find a way to do this real-time.

I'm not looking for someone to do this for me, but can someone point me in the right direction of a tutorial or something that is similar so I can build this into my program?

JQuery :: Countdown Real-time Updates

Sep 21, 2010

I have been using the jquery countdown plugin made by [url] for a while and while I am pretty familiar with it, I haven't been able to accomplish what I want for one of my projects.

I want to be able to add hours/minutes/seconds to a countdown in real-time by clicking a button.

Let's say I have 2 countdowns. They both get their ending date from a mysql db, e.g: 2010-09-26 00:00:45 and 2010-09-27 14:45:00

When I click a button, I want the countdown Y to increase by the X amount of hr/min/sec, update my ending date in mysql, and update my counter for every visitors to see without having them refresh the page. I have tried messing with ajax, but wasn't able to accomplish anything close. (I got it to update every 1 sec but it would flicker then)

Changing Element Styles In Real Time

Feb 6, 2003

I'm using sliders to change text colour dynamically; at the moment, I'm doing it by iterating through the getElementsByTagName collection; like

paraAry = document.getElementsByTagName("p");
paraLen=paraAry.length;
for(j=0;j<paraLen;j++){
paraAry[j].style.color = "rgb("+bodyColor[0]+","+bodyColor[1]+","+bodyColor[2]+")";
paraAry[j].style.borderColor = "rgb("+textColor[0]+","+textColor[1]+","+textColor[2]+")";
paraAry[j].style.backgroundColor = "rgb("+textColor[0]+","+textColor[1]+","+textColor[2]+")";
}

But blatantly it's well inefficient; is there a better way to achieve this - like just a single property I can change to make all elements of a given name change.

Save Real-time Data In Client PC?

Oct 9, 2009

I am using Ajax and Javascript to show real-time data on the web page. On my web page, a 4-digit number is displayed in a text box and this number updates every 10 millisecond automatically to display real-time data (show 100 numbers per second).

What I would like to do is to save the lastest 10 second data in the local PC (client PC) when client clicks a button on the page. Is that possbile with Javascript and Ajax? Or is there any other ways to sort it out?
