First off by let me stating that I am not a great web devloper nor am I a good with css / javascript. I am creating this website for a friend of mines company and I have one problem.The problem is that the navigation menu on the right side will not remain fixed how i want it to be. I spoke with many people and they all said that this cannot be done with css considering your layout and because it needs to dodge the headers and the footer. I basically want this div (sidenav on the right) to scroll along the page as users scroll up or down but it can not interfere with the header or footer. I do not want the right side navigation to go over the content or out of the wrapper. I want it to stay in the same position in all aspects - left / right / top / bottom. Here is a link to the site [URL].
But what goes in href if you don't have anything to actually link to? One example is a page I've written that is entirely self-contained, and all href's that drive the interface end up pointing to #. Is this acceptible in edge cases like these with the unobtrusive approach?
If someone has JS turned off the markup is essentially meaningless, so I was wondering how people deal with this lapse in the separation between behavior and structure.
which is placed in the body section of the page. Anyhow, my problem is that it works fine, but only once, right as the page loads. I have tried removing window.onload, but then it doesn't work at all. How can I get this to work every time I blur from the text field?
I want to display the div marked 'General overview' by default, and to hide all of the other divs (section1, section2, section3 and section4) but would like to swap out the 'general' div with the other divs as the corresponding links are moused over.
e.g. mousing over the Section 2 link will replace the 'general' div with the 'section2' div. On mousing out, it will revert back to the 'general' div. Mousing over the Section 4 link will replace the 'general' div with the 'section4' div. On mousing out, it will revert back to the 'general' div. Etc etc....
I was reading through a book that talked about unobtrusive javascript, and it gave this example of how to trigger a function instead of using an inline onmouseover event handler.
document.getElementById("RandomElementId").onmouseover=RandomFunction; I thought this would be cool, but I can't seem to find a way to pass parameters to the function this way. I assumed you just use RandomFunction(parameter1,parameter2); but no go.
Is there a different syntax for this, or does this technique forbid using parameters?
From my understanding the main feature of unobtrusive JavaScript is to remove event handing from the markup.The main reason for doing this is to avoid repetition of code.There are also other reasons but that is the main one. e.g. no having to write <tag onclick="function()" > over and over again. This traditional event handling method makes code less maintainable.However is it worth writing unobtrusive code when we consider the following:
1, Server sider scripting laguages can be used to avoid code repetition. e.g. we can use a loop to add multiple onclick event handlers to all the elements of a navigation list. Thus we would only have to write onclick="function()" once.
2, Unobtrusive coding makes the code harder to follow.It is easier to look at the markup to find out what happens when an event occurs on an element rather than having to look through wades of JS code to find the correct event listener. This is especially true when a team is working on a project. It is easier to find out what another person has done when the traditional model of event handling is used.
3, Unobtrusive coding means longer and more complicated code. Also there there is a need for having to deal with browser differences.I know this can be reduced using libraries such as JQuery. Is it worth using such a library?
without outside extensions (http://remi.org/2009/01/06/using-firebug-to-debug-unobtrusive-javascript), how does one debug javascript events on a webpage that primarily relies on unobtrusive JS events? for instance, i have a website i log into that has a "submit" button. the button itself only has this code:
obviously, the only way that it can submit the form is to use javascript. and it's obviously unobtrusive in this case.consider the fact that it isn't my webpage, and i don't want to try to put random breakpoints everywhere blindly.
I have an old web application I did where browsers with dynamic capabilities received a drop down menu on the top of the page and a fold out on the left hand side of the page and non-dynamic browsers received two static menus. This was done via server side detection of browser capabilities and branching the application. Over time needless to say the capabilities between the dynamic and static sides got seriously out of whack.
Now the drop-down menu was not done unobtrusively, it was done via mouseovers and the like.
Obviously it makes sense to change the menus to be done by catching events. But I would also like to redo the dynamic and static branching.
The way I figured would be as follows:
The static menus are placed inside of noscript elements. The dynamic menus are loaded with display set to none. Script writes in a new css changing dynamic menu display to block.
As I understand noscript is considered bad via unobtrusive javascript theory, however I have a hard time seeing how one could make a menu that would display properly as a static menu yet also function as a drop down or fold out (especially fold out), collapsible expandable menus are easy since they basically have the menu order placed in the structure needed.
So I'm wondering if anyone has reasonable suggestions on how to succeed.
On another subject, anyone know what the effect of a bunch of links inside a noscript element that mirror a bunch of links in the normal page will do to Google's algorithms?
I am trying to create a basic unobtrusive form validation function but I am having some issues/questions. Basically I am checking if any of the form fields have <= 3 characters, and if they do so, then I make those fields' backgrounds and borders red. Also in the empty <span> tags I insert an error message. My issues/questions are:
#1: So when I say if (fieldVals<=3) this means that the errors should appear if the values are 1,2 or 3 characters long, right? It does not do that though, when I insert one character in any of the form fields the errors go away, but they should not, right?
#2: How do I cancel the form from submitting if errors are visible and vice versa? When I use the return false when errors are visible, the code does not even run. What is going on? return true does the same.
#3: When I use a submit button(type="submit") instead of just a button(type="button"), the code does not run? What am I doing wrong?
I am not trying to use this on a website, I am just trying to learn how to use unobtrusive javascript. That's why I am only checking for empty fields. If I learn how to do this first, later I will try to add email check, date check etc.
I have a simple button in my HTML. I also have a function in my external JavaScript file. This function calls an alert box with some text. Now, I also have a global variable in my JavaScript that gets the button by id, then assigns the onclick event handler to it which in turn is assigned the call to my alert box function. Simple right?
Problem: The alert box shows up when the page loads as well as when the button is clicked. This is not desirable. code...
I have a div with headers. Of course, when there are too many rows, you have to scroll and lose the headers of the form. How can I accomplished "fixed headers?" so that they're always visible?
I'm having an issue with a problem with Javascript on my website. Please note I didn't create the javascript someone else did a long time ago and I'm using it with their permission and they are no longer on the internet or in webpage ways.
The basic problem is that these pages work just fine in IE6 and IE7 but with Firefox 1 and 2 they work but not as they are suppose to. Code:
Anyone know how to make an svg circle radius fixed (i.e. not affected by transforms)? I tried adding px or cm, e.g. r=ཋpx' but it just generates an error.
what im trying to do is get a paragraph tag to display like a textbox but put links in there which can be clicked on. (so a textbox wont work). i want each <pto have the same length (regardless of link length) so they line up ok when placed in rows.
I only have a table that is a fixed height within which to place a menu of links.
There are more lines of links than will fit in the table. So i need to have ascroll bar on the right within the table to access the rest of the links.
I have played with code for drop down menus and opening in frames etc, with no real problem, but in this instance i have to display them in a fixed size table, can anyone point me in the right direction.
I have a "Roaming Companion" on my sites index page (www.studylinks.org - look for the red R) and I would like to fix its size and disable the expand and maximize functions. I assume it's in the Java rather than the HTML or CSS but do tell me if i'm wrong.I'm new to the forum so please forgive any posting/etiquette errors on my part. Javascript Document
function doPopups() { if (!document.getElementsByTagName) return false; var links=document.getElementsByTagName("a");
I just thought this might require some javascript, so I posted this here. Anyway, how do I create an element that is absolutely positioned first, and then, when it goes to the top of the page, it becomes fixed?
I am trying to have a sidebar that has a fixed position so it scrolls with the page, but can be hidden (toggled) like this: only on the right side of the pageI am going nuts trying to figure this out: I've tried dozens of scripts but everyone has problems working together
I'm having a problem with css positions !! i want the position of an image to be fixed when the user scrolls till some point and the position should be set to relative after that
I have a <img scr="mypic.jpg"in my html. I would like to display the image by width=200 if the image width is larger than 200. I also would like to display the image by its real width if the image width is smaller than 200. How can I do it?
I've written a small javascript library to help automate Ajax requests and the like. One of the things I want the library to do is display a "Please wait" indicator in the upper right hand corner of the viewport while requests are processing.
What I do is append a div element to the document body, set it's position to fixed and set the top and right to 0. This works great in Firefox and Opera, but not in IE.
In IE this element displays in it's normal position (at the bottom of the page) as though it has a position: relative or position: static.
I've seen tricks using css and things like height: 100% and overflow- yL auto, but these never seem to work when I try them programmatically. And because I may want to distribute this, I don't want to require that the end user go through any gyrations for ths to work.
