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.
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.
Im creating a javascript content expander and would like to know how to create it so it changed the image from an down arrows to open the box, and a down arrow to close the box.Here is my current code.
Code:
<script type="text/javascript"> //var persistmenu="yes" var persisttype="sitewide"
[code].....
I want the <div class="rightnews"> thing to change from an up arrow to a down arrow.Here are the icons im using.for the box to contract:
I use a small piece of JS code to make different elements on the page show/hide when clicking a link, based on id:
function toggle( targetId ){ if (document.getElementById){ target = document.getElementById( targetId ); if (target.style.display == "none"){ target.style.display = ""; } else { target.style.display = "none"; } } } Then HTML looks like this: <a href="#" onClick="toggle('news'); return false;">Show/hide news</a> <div id="news" style="display:none">BlahBlahBlah</div>
This works. Initially the element is hidden (with style="display:none" property of the element), and the script gets its id and changes its display property to "block" when clicking on a link.
But when Javascript in a browser is turned off, the elements to show are all hidden, and there's no way to see the content of the element.
My question: is there a way to hide toggled elements on page load with JS, so that when it's turned off the hidden content is shown?
When I place the script.php in other servers it works fine (content can be viewed) except with one server, it doesn't return anything (just blank screen). What could be the possible problem, is it a hotlinking issue or something else?
i made this javascript using the new "screen.width" property, which would make it easy to center content in a webpage no matter what the screen resolution is. Here it goes:
<html> <head> <script type="text/javascript"> function pos_center() { var content = document.getElementById("carrier") var width = screen.width var contentwidth = content.offsetWidth value = parseFloat((width - contentwidth)/2) content.style.marginLeft = value } </script> </head> <body <div class="body" id="carrier"> </div> </body> </html>
The "body onload" makes the page first load all the way to the left, and then after completely loading switches the content to the center, that is dynamically gross. Now, instead of using the "body onload", is there any other way that i can make the content appear. Seeing that there is no "onbeforeload", there must be another way to solve this.
This forum thread discusses the SitePoint article 'Re-Write a Layer's Content with Javascript' by Peter Todorov.
"How can you can replace the content of a Web page without additional requests to the server? The answer uses layers in JavaScript - Peter explains all."
I have a company that has a group of companies under it. I plan to add 4 company logos on one front page, and when the user mouses over one of the logos, I want a table below to change and show a description of that company.
The images that they will be mousing over will also need to change, and the table that will change should be able to carry a static message such as "Hover your mouse over the logos above to find out more".
I would like to build an HTML page that has four content areas. The first with 3 links that when clicked chage what is shown in the other 3 - and so changing the default content in these sections. The content for these sections will be contained in seperate HTML files sitting on the same server.
I understand this can be done without refreshing the page and believe JavaScript and Ajax is the best method to do this. Any advice?
I'm sure some wizard will tell me this is a classic example of "piece of cake"; in which case I bow and promise to listen In case I've struck granite rock, feel free to throw questions my way and I'll tell you if I've tried it or not.
I have a file, main.php (I know this is the JS-forum, bear with me). It outputs HTML and inline Javascript functions. When the user clicks on a graphical "tab", that tab is activated, and an ajax call is made to fetch.php with some specific parameters. Once the ajax request has completed, a given innerHTML container on the now active tab is filled with the stuff that fetch.php outputs.
So far so good.
The problem is that the stuff that fetch.php outputs is partial pure HTML and partial inline javascript. And this is where it gets tricky. If I declare an inline javascript function in the returned data, Firefox (and I suspect MSIE) refuses to understand that the function is there. It simply doesn't exist (!).
Using the Web Developer add-on for Firefox, there's an option to look at "Source code" and "Generated source code". The output from these two differ in that when I view the "Generated source code", I see the dynamically inserted javascript/HTML from fetch.php, whereas viewing "just" the source doesn't.
What did I do wrong? How do I get the browser to find/accept/activate the javascript code/functions that were inserted dynamically? I cannot put them in a .js file and include it, since they need to be dynamically created, and I cannot use eval() since that executes javascript "as is", in which a function will not be executed unless called.
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];
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 am using a switch function to toggle those links for display and unlink image will be hidden. But I have just duplicated the first block of javascript for the second tab, it didn't work. This is the first block of switch function, it works for first tab: 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!
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
below that is a "menu" when one of the items are clicked it moves the information pulled via php from whichever one is clicked to the inuse div... as you can tell i am new to js and am trying to start out doing some different things with menu onlick items etc..
I have a few links on my website as follows: <a href="javascript:switchid('a6');">Link 6</a>but when I view source it comes out like this: <a href='javascript:switchid('>Link 6</a>
