JavaScript - Display A Time-dependant Image When Opened With A Browser?
My question is twofold. First, is there a way to have a javascript file display an externally hosted image when opened with a browser? I mean such a way where the URL of the javascript file can be referenced by an html document and display an image?
Furthermore, is there a way to have this be a different image depending on the time of day and timezone of the user, specifically one image in the morning and a different image in the evening? I apologize if I posted this in the wrong section, but I wasn't sure where else this could go. Similar TutorialsGood Morning Everyone, My first post here so hope i get the format right The problem I have a menu on a new website im developing. The menu is going to be within a PHP include file. I need a way of (using JS) the current page having its menu item with a different image to the others e.g. a "selected" image. The code im experimenting with, and which may shed a bit more light on what im trying to achieve is as follows: Code: var url = window.location.pathname;
var filename = url.substring(url.lastIndexOf('/')+1);
if (filename = 'about.php')
{
$('#about').attr('src', 'images/Nav/about_selected.png')
}
else
{
$('#about').attr('src', 'images/Nav/about_over.png')
}
I am using jQuery for this project thus the jQuery code being thrown in there. The logic of the code iv made is, IF the page is 'About' then the 'About' menu button should display 'about_selected.png'. I hope this makes sense and a solution would be much appreciated. Thanks! I have a page with 6 dependant drop down boxes. I also have a text field with a copy to clipboard button. What I need it to do is send the drop down selections to the text field to be copied along with some static text. The resulting text field would look something like this after the selections are made. "Per Wizard: Choice 0: Selection 2, Choice 1: Selection 2, Choice 2: Selection 4 ..." Can this be done on each line as a second onChange event? Code: <html>

I have a form that has several dependant drop down boxes and copies all of the selections to a text box so you can paste the results to another location. I am using this in training to simulate the selections they will make in the actual system. I would like for the last selection to be a link instead of another drop-down box so that I can direct them to more information (a step by step) based on their selections. I am including a scaled down version of my code below. It actually has 8 possible selections for code 1 and 83 for code 6. I have looked at http://www.outfront.net/tutorials_02/faq.htm#DropDown but am not sure how to adapt it to work with the dependant boxes. Any help would be greatly appreciated! Code:

Hi, Sorry to bother you all with this but I'm really new to JavaScript and can't figure this out but I'm sure it's probably quite simple for you guys. I've been using this bit of code to limit the number of characters in a text field (taken from http://www.shiningstar.net/articles/...reacounter.asp: Code: <SCRIPT LANGUAGE="JavaScript">
function textCounter(field,cntfield,maxlimit) {
if (field.value.length > maxlimit) // if too long...trim it!
field.value = field.value.substring(0, maxlimit);
// otherwise, update 'characters left' counter
else
cntfield.value = maxlimit - field.value.length;
}
// End -->
</script>
<form name="myForm"
action="/articles/articles/javascript/dynamictextareacounter.asp?ID=<%=siteID%>"
method="post">
<b>One Function to Count and Limit Multiple Form Text Areas</b><br>
<textarea name="message1" wrap="physical" cols="28" rows="5"
onKeyDown="textCounter(document.myForm.message1,document.myForm.remLen1,125)"
onKeyUp="textCounter(document.myForm.message1,document.myForm.remLen1,125)"></textarea>
<br>
<input readonly type="text" name="remLen1" size="3" maxlength="3" value="125">
characters left
<br>
<textarea name="message2" wrap="physical" cols="28" rows="5"
onKeyDown="textCounter(document.myForm.message2,document.myForm.remLen2,125)"
onKeyUp="textCounter(document.myForm.message2,document.myForm.remLen2,125)"></textarea>
<br>
<input readonly type="text" name="remLen2" size="3" maxlength="3" value="125">
characters left
<br>
<input type="Submit" name="Submit" value="Submit">
<br>
</form>
What I'd like to do is make the background colour and maybe the font colour change on the 'characters left' field depending on the value of that field. So most of the time the colour is green but when the field = 0, the background colour changes to red. Can I just add to the function above or will I need a new one? If anyone could help, that would be great Cheers hi all, im looking for a script that does the following when the page loads "text1" is displayed. then on the next line 2 seconds later "text2" is displayed and test1 is still displayed. and i need this to go to 5 lines so the final project should look like --- text1 text2 text3 text4 text5 thanks Pretty simple, I just want to display a <div> after say 20 seconds or any predefined value. Ideally with jQuery
I'm sure this is old news, but I am trying to use the CSS Horizonal List Menu script on JavascriptKit and having some display problems. http://www.javascriptkit.com/script/...stopmenu.shtml It works well except that I can't seem to get the CSS settings to display the same way in FF and IE. I can use pixel settings for the box size to get the menu across the entire screen in FF, but it only goes about 80% of the way in IE. If I maximize for IE, then the FF menu wraps. The % options for box size don't seem to work either. I am using Dreamweaver 4 for css settings. Is this just a limitation in the way the two browsers interpret the code? If there is an easy fix I could try it, otherwise I can live with what I have. I just need to know if there is some way to deal with it or not. If interested, the current version is at: www.chromafrica.com/template/template2.html. Hey guys. So I've been learning PHP and MySQLi for the past few weeks and it's going brilliantly! I intend to start learning JS over the Xmas holidays, but right now I only have a very basic knowledge of it. I was just wondering if someone could point me in the right direction on how to do this, as I think i should be pretty easy. After someone changes something in the admin area [e.g. the position of an item] I want to be able to have a small div display at the top of the screen saying something like "Position Updated!" and then have it fade away after 2-3 seconds. Just wondering if there's a fairly easy way to do this, or would I have to go get something like MooTools, etc.? Thanks a lot! Hi! First post here! Would really appreciate some help on a javascript that would display the time elapsed since a particular visitor last visited my webpage, using cookies. So basically it should show something like: "You last visited my page 2 days & 12 mins ago!" I've a little background in java but none in javascript... Thanks so much! I was trying to display time of last visit along with login name.. can someone help me on this pls? How can I draw a cookie where number of chocolate chips represents the number of seconds and the number of bites represents the number of minutes. I want to show the passage of time on a clock that looks like items are being added to the display according to the number of seconds and minutes. Maybe using a mouse input aswell! Please guide.:confused: I use the Processing Software Hi, I want to display my listings like they do he http://www.ticketnetwork.com/performers/concerts/a.aspx The code on my end calling the third party service looks like this: <script language="javascript" type="text/javascript"> document.write('<script language="javascript" src="http://###########.com/?bid='+####+'&sitenumber='+#+'&tid=event_names&pcatid=2&showcats=true&title=Concerts Tickets"></' + 'script>'); </script> How do I make it only display one letter at a time? I believe some variation on the sort method might work... I have this code which converts Fahrenheit to Celsius. Now, I have to have a counter that displays the amount of times I have made a conversion. I have no clue how to do this. This is the initial code:
Code: <html>
<head>
<script type="text/javascript">
/* Converts given centigrade in one text box to farenheit in another */
function convert1 () {
document.getElementById("output").value =
document.getElementById("input").value*1.8+32;
}
</script>
</head>
<body>
<p>Then enter the input and view the output</p>
<input type="text" size="15" id="input">
<input type="button" value=" ==> " onclick="convert1()">
<input type="text" size="15" id="output">
</body> </html>
I don't know how to approach this so I tried different things.... Code: tml>
<head>
<script type="text/javascript">
/* Converts given centigrade in one text box to farenheit in another */
function convert1 () {
document.getElementById("output").value =
document.getElementById("input").value*1.8+32;
}
function counter()
{
if (function convert1().onclick==true)
{count++;}
}
</script>
</head>
<body>
<p>Then enter the input and view the output</p>
<input type="text" size="15" id="input">
<input type="button" value=" ==> " onclick="convert1()">
<input type="text" size="15" id="output">
</body> </html>
but then I did some research and it said I couldn't do that.... so I tried this: Code: <html>
<head>
<script type="text/javascript">
/* Converts given centigrade in one text box to farenheit in another */
var count=0;
function documentClick()
{
document.getElementById('clicked').value = ++clickCount
}
document.onclick = documentClick;
function convert1 () {
document.getElementById("output").value =
document.getElementById("input").value*1.8+32;
}
</script>
</head>
<body>
<p>Then enter the input and view the output</p>
<input type="text" size="15" id="input">
<input type="button" value=" ==> " onclick="convert1()">
<input type="text" size="15" id="output">
</body> </html>
I think this last code is correct, the problem I have now is that I don't know how to call it to just display as text under the buttons and conversions. I'm looking for some way to display it like ("you have made"+ count+ "conversions");. No boxes or buttons, just text and I don't know how to call for this after the </script>, inside the body. I am new at all this and would appreciate any help. Thanks. It should look like this. Hello, I am trying to get this sliding panel to automatically be open when the page loads.

Here is my scenario, i have a html that allows the user to retrieve .pdf file from the server. If the users are trying to open the html again, mean the user open a new tab/window to the same html url, the window will prompt the user that the html is already opened. The user will need to close the old html tab/window first before open a new one. Is it possible to stop the users to open the new same html file before he/she closes the old one ? Is there any link that teach the tutorial about this ? I am wondering do i need to use cookies in the browser to store the url in order to compare to the new tab/window url ? Thanks for helping.

Background: I am trying to create a schedule website, the schedule has say 20 items and I want it to display the current "active" event in the schedule, 1 previous event and 3 future events so a total of 5 items from the schedule. An event can range from 30 minutes to 2 hours long, so simply using the above code will not work. It needs to take the minutes into consideration as well. Let me know if you have additional questions. EDIT: 17-Mar-12 @ 12:37PM I would rather not use a bunch of if statements. (http://www.codingforums.com/showthread.php?t=250358) The schedule could change mid day so having to go through and edit a bunch of if statements would not be ideal When the site loads up, invite the user to enter their name and then display a message at the top of the document which will say< good morning, evening, or afternoon >, based on the time they access your site, welcome to <insert the name of your site> This is the question how do i do it?? Hi, I need to display alert when I close the browser window. Now I am using the following code to display the alert. But the alert is getting displayed even I click on any links.
