Is there a way where I can "guess" what relative speed the user's
connection is?
Currently, the client is wanting some graphical intensive content and
I'd like to be able to warn users on dial-up to allow them to go to a
"gracefully degraded" version.
I thought of simply putting up a question for users to answer but the
client would rather it happen, more or less, automatically.
I've been driving myself crazy the past couple hours and can't figure this out. Here is what I need to do:
Have a select box like this:
<select name="dropdown">
<option value="option1">option1</option>
<option value="option2">option2</option>
</select>
Then when one of those options is selected, the appropriate div tag is displayed:
<div id="option1">
Div 1 Text
</div>
<div id="option2">
Div 2 Text
</div>
This seems like it should be really simple to do, but I can't figure it out.
im trying to have two links at the top of a page one is FEED and the other is INFO when the page opens it should be on feed, and if i click info it switches to info and the feed button becomes available to click again, at this time hte page content should switch as well.

Does anyone have a good java script that I can add to my page so that the same user doesn't pound my site and use all of my bandwidth?
View 12 Replies View RelatedI found this on JavaScriptKit. It checks to see if the site accessing the data is your domain. I found it pretty cool.
//Beginning of "test.js" file
var accepted_domains=new Array("wsabstract.com","javascriptkit.com")
var domaincheck=document.location.href //retrieve the current URL of user browser
var accepted_ok=false //set acess to false by default
if (domaincheck.indexOf("http")!=-1){ //if this is a http request
for (r=0;r<accepted_domains.length;r++){
if (domaincheck.indexOf(accepted_domains[r])!=-1){ //if a match is found
accepted_ok=true //set access to true, and break out of loop
break
}
}
}
else
accepted_ok=true
if (!accepted_ok){
alert("You're not allowed to directly link to this .js file on our server!")
history.back(-1)
}

What I'm doing is taking the parts of my web site that apear on every page, for example the tags from the first <html> tag to the <body> tag, and I just put some JS code into an external file that tells it to write that same code to the browser, then I call the external file where I had the original code.
That way the external file gets cached and they don't have to re-download that part of the code every time.
Combining this, with some other things including gzip I've been able to get my main index page down to 300 bytes, not including images, css files or js files, which are only downloaded once because of caching anyways(and they aren't that big in size themselves, either).
Of course this wouldn't work if you don't want to alienate people who don't use javascript, but 9/10 people do so for some this might be helpful...
Also, this still works with dynamic content as well. for example what I did for my main page where I display the news in little "news boxes" as I call them which are basicly divs setup so they look nice visually... what I did was make a function in the external JS file that accepts the different parts of the news box such as subject, body, time/date of post and who posted it, and then it creates the HTML for it. Then it's really easy to change the look of the displayed news by just changing the js file.

View 3 Replies View RelatedI'm trying to come up with a script and I'm having a heck of a time...
I require users to enter the size (in MB or KB) of the attachment they
wish to transfer/upload. As they enter the number and move over to
the next field (using onBlur or...), I would like a popup/alert window
warning them that this attachment size would take "x" amount of time
based on a speed of 24 kilobits per second (kbps). If they are happy
with the amount of time, I wish to allow them to click OK (to carry on
with the transfer) or Cancel/No to cancel it.
I have some function to Preload images and make MouseOver etc..
But when a put a Switch statement in one of my function (MouseOver), a
receive an error on body load in my preload function.. did someone have any
idea why ?
Here's my switch code :
function setOver(num)
{
var txt;
obj = eval('document.getElementById("image' + num + '")');
obj.src = imagesHover[num-1];
txt = '<img src="' + imagesInfo[num-1] + '">'
document.all("infoDiv").innerHTML=txt;
document.all["infoDiv"].style.display='block'
Switch (num)
{
Case 1: alert(num);Break;
Default: alert("hello");Break;
}
}
I'm trying to make an 'on' 'off' switch
the idea is for imgA to 'toggle' with imgB onMouseDown (onclick is used to call a function)
I can get the image to swap once but not back again. I have no idea if the way i'm attempting it is even close.

function imgswap(){

I'm trying to install a menu for my website. I am using a script I found here: http://www.dynamicdrive.com/dynamicindex1/switchmenu.htm.
The code works great, but I would like to customize it slightly. Instead of being a vertical menu, I would like it to be a horizontal one, with all the main links at the top of the page, and with each link opening a horizontal sub menu beneath it.
I managed to create a horizontal list by changing the 'div' to 'span' and altering the HTML and CSS slightly. Now I have a horizontal menu that opens submenus when I click!
My only problem now is that instead of opening each submenu below all the links, it opens it below the link in question. So, for instance, let's say I have three links: Info, About, and Contact. If I click on 'About', it opens up a submenu under Info and About, and pushes Contact down to a new line below the submenu. If I then click on 'Info', it closes the previous submenu and opens a new one below Info, with About and Contact in a new line.
My JavaScript skills are pretty poor, so I was wondering if someone could help me identify where in the JavaScript I need to make changes so that the the submenus open below ALL the menu elements. Code:
This is my first time using the switch statement. I would appreciate your suggestion on how to do this properly. I am trying to get customer age which is (age) and compare it with the monthly rate then the text msg will display in the textarea. Also, I am having trouble figuring out how I can defined my monthlyRate in the switch or do I need to this outside of the switch? Code:

I'm trying to make a printable version of a webpage using the css @media tag. On the page is a javascript which works great for the on-screen version but I need to find a way to switch it off when printing as it hides content.
Beyond building a separate page I can't think of anything obvious!
As I can remember this is not allowed in Java:
int x, y, z;
switch(x,y,z){
case 1,2,3:
System.out.println("Hep");
break;
}
But what about in JavaScript, or are there some other kind og syntax for switch?

I'm using a script that changes between 2 images when I click on the image: e.g. (An arrow that is pointing up and another that points down) When I click on the up arrow it changes to the down arrow and vice versa.
Now, when I click on the arrow it changes for the first time, but it cant be repeated. My goal is to let it change to the other image whenever i click it.
Code:
function changeMySrc(i) {
if (i == 1) {
document.getElementById("Img1").src="Images/up_arrow.jpg";
} else if (i == 2) {

i have a div up here and the id is inuse it chooses the first selection automatically to use
