JavaScript - External Scrollto Link
Thank you in advance for your help with this.
I have two pages. One page with thumbnails and another page with the actual gallery. On the gallery.html page I can scroll to my 5th image in the list by the following code: onclick="myScroll.scrollToPage(5,5)" I want to achieve this same effect from the index.html file into the gallery.html file. I have tried using anchored links like #image5, but that just messes up the page and the iscroll script I am working off of. Thank you again anyone who can help.

I have a link in the page A. I have two iframes in the page B. In practice, the link in the page A must open the page B and the link's href must open in the second iframe of the page B. Is there any script that does this? I am trying to have a text link above Google Maps link to a marker on my map. When the link is clicked, the map will automatically center itself on the marker. I already have the custom markers and locations, I am just not that good with Javascript and jQuery to figure it out. I tried to use Code: <a href="javascript: map.panTo(new LatLng(25.2, 105.7))">Mexico</a> and the link shows up, but nothing happens.

Hello, I posted this at another site, but am still at a loss so I hope I can get some help here I am at a complete loss with this plugin. And if after reading my post, someone can come up with a better, less frustrating plugin, I would really appreciate it. The plug-in author's site is: http://flesler.blogspot.com/2007/10/jqueryscrollto.html. The gist of it is that I am making a website for a restaurant. They want the menu to horizontally scroll between the sections of food, and within each section, have a vertically scrollable (via scroll bar) text menu in two columns. When you click on the section in the nav menu, it's supposed to take you to that food section via horizontal animated scroll. The link below is the sample page I'm testing on, and an image is attached to show you the idea of what it's supposed to look like: http://www.bqcreative.com/gcc2/menu.html That is the sample page with the JQuery.ScrollTo plugin installed. When I shrink the page, it looks like the animation *is* working (by the window scroll bars moving), just not correctly, since it's not moving the divs. Image of what each food section should look like: Maybe this is a case of me not having the divs set up correctly with CSS? I'm not sure, I've dug myself into a messy hole... please help HTML (with irrelevant code removed): Code: <div class="menunav">
<ul>
<li><a href="#" onclick="$.scrollTo('#appetizers', 1500, {easing:'elasout'}, {axis:'x'});">Appetizers</a></li>

I have a menu on my site that is not working in IE. It works fine in Safari and Firefox, but it doesnt even open the link for the correspoding button. It just stays on the home page. Someone told me it was the google analytics, but I changed the menu portion of the code and added the gaq_push and the trackEvent, but it's still not working. Help guys, thanks.
At the bottom of my document (pageA), I have an iframe like this: <iframe src="pageB.html#anchor" ... pageA opens with the iframe at position 0,0. <body onload="window.scrollTo(0,0)" ... works for FF but not for IE(8). How could this be fixed in IE? Hi I am having a problem with that code : Code: <!DOCTYPE html>

onclick="$('#sections').scrollTo($("#s5")); is not working thank you for helping Hey guys, im pretty new to using Jquery and coding period. i came across a problem with the .scrollto plug-in and i have searched up and down for an answer and none would really solve the problem. im trying to run .scrollto to jump from one div to the next with a smooth animation in a horizontal website. this is what the head tag looks like so far <script src="scripts/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="scripts/jquery.scrollTo-1.4.2-min.js"></script> <script src="scripts/jquery.localscroll-min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { $.localScroll(); }) </script> i tried removing either local scroll or scrollTo and see if there was a conflict but that wasnt the case. ive seen the script run on a webpage without having to add $.localScroll(); to every link, right now it just doesn't move at all. any help would be greatly appreciated. Hey everyone, I'm a NOOB, yeah, its hard at the beginning but you have to start somewhere right? Anyway I'm currently building a website that incorporates JavaScript, ActionScript, and the usual CSS and XHTML, but I've run into a bit of a snag. Our wishes for this grass roots web page was to add Ariel Flesler's ScrollTo jQuery plugin to our navigation, to dynamically slide our entire pages from left to right, right to left, upon the users choice. But, our navigation buttons, on our homepage in particular, are within a SWF file. Now is it possible to trigger the ScrollTo effect from buttons within a SWF? If not, can you provide a alternate solution to this dilemma? Thank you all, and I'm happy to be a new student of this community. Hi, I'm having a problem with my page not resetting to the point where the user clicked on an element. I believe this to be a javascript problem, however, if it is not I would be glad to move it to the proper forum. What I have is a page with a div that contains a large image (a map). the dims are 1237 x 1550. I am using a browser window resized to approx. 800 x 600 so that I can simulate a smaller screen viewport. The page has links that are scattered about the map (positioned with css) and what I want to do is launch a video using the HTML5 video tag when the user clicks on a link. The video is supposed to open in the center of the users viewport and then dim the map div, which it does, however the page resets its position after the js function and aligns the page back to the upper left corner of the browser window. If the user had scrolled (both x and y) to the max of the scroll bar, then this will be fairly frustrating to have to keep moving back, thus my dilemma. I tried using scrollto to reset the scroll back to where the user was, but this is not working. What's funny is if I put an alert at the very end of the function, the page displays properly (video is centered on the screen where the user was in their viewport) but resets as soon as the alert is closed. I then tried using location.reload(false), but this keeps the function from running properly (the page shows properly for a fraction of a second then resets back to a newly launched page). Below is the code. Also, this has only been tested with FF and Chrome on my local drive. It is not anywhere on the web right now. In chrome, the page resets to the top only. I'm really not interested in making this work with IE since this is for personal/family use. Your help is greatly appreciated. Code: CSS
body {
background: black;
text-align: center;
vertical-align: middle;
}
div#bkg {
position: absolute;
text-align: center;
z-index: 1;
}
p#day1 {

vidWin.setAttribute("style", "position: absolute; left: " + leftNum + "px; top: " + topNum + "px; z-index: 255;");
// create the source tag
var vidSrc = document.createElement("source");
vidSrc.src = "videos/" + srcVid;
vidSrc.type = "video/ogg";
vidSrc.codecs = "theora, vorbis";
vidWin.appendChild(vidSrc);
document.getElementById('bkg').style.opacity = 0.5;
document.body.appendChild(vidWin);
window.scrollTo(xPosOff, yPosOff);
// tried this, it didn't work
// location.reload(false);
}
HTML

<img src="images/pic1.jpg" />
<p id="day1"><a href="#" onclick="showVid('oggtest')">Day 1</a></p>

Hey guys, This is my first time ever posting in a programming forum so please be nice! :) I'll admit right away that this is for a homework assignment, but I really did try to solve it myself before I decided to post here. The instructions are to have a confirm box pop up when links with the HTML class value "external" are clicked. If the user clicks "OK" they should be directed to the linked page. If they click "Cancel" they should not be directed anywhere. Here's my code: Code: function checkClass() {
var links = document.getElementsByTagName("a");
for ( var i = 0 ; i < links.length ; i++ ) {
var link = links[i];
if (link.className == "external") {
link.onclick = clickHandler();
}
}
}
window.onload = checkClass;
function clickHandler() {
if (confirm("You clicked an external link. Do you really want to leave this site?")) {
return true;
}
return false;
}
The problem is that the confirm box is triggered on page load and not on link click. I know I wrote Code: window.onload = checkClass; but how else should I call the function? I thought Code: if (link.className == "external") would keep it from going as far as to the confirm box until an external link was clicked. Thanks for pointing me in the right direction, Johanna Hello, how could I run an external (but still on the same server) ".js" file from a <a href> or a button? Is it possible and how? Thanks. If you need any details just ask. Hi, I hav linked external js (ext1.js) to my app.html page. Now in the ext1.js, I have a function like [CODE] function onwindowload(){ //Access HTML element and append external js 2 (ext2.js) here }[CODE] //Access HTML element and append external js 2 (ext2.js) here--->I donno how to add external JS here. Even if i add the external JS here, the JS uses document.write fn. which replaces entire page. Please suggest a solution Hi, I'm new to JavaScript and I'm having a bit of trouble understanding something that seems relatively simple. When I make changes to CSS in JavaScript using '.style' I'm changing the attribute values of inline CSS. Can I use JavaScript to change the attribute values of rules in an external CSS file? I have no CSS in my html and would like to know if I can grab the values of attributes in an external CSS file using JavaScript. Thank you. I've been playing with this workarouns for literally years, but I'm getting fed up with it. Can anyone here suggest a better way of dealing with the following conundrum - or at least clarify why it occurs? When I have an external stylesheet I can't access the properties assigned therein. I'll give an example - HTML/CSS/JS are all inseperate files - but everything is called into the HTML as you can see. HTML: Code: <head> <script type="text/javascript" src="js.js"></script> <link href="style.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="box" onclick="showWidth()"></div> <body> CSS (style.css) Code: #box {
width: 200px;
}
Javascript (js.js) Code: function showWidth(){
var box = document.getElementById('box');
alert(box.style.width);
}
Now the alert fired by showWidth() is empty - meaning that javascript can't see the width of the div element 'box' Now, if I assign width as part of the style attribute of the div javascript thus: HTML: Code: <head> <script type="text/javascript" src="js.js"></script> <link href="style.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="box" onclick="showWidth()" style="width: 200px;"></div> <body> javascript can see this and the alert fired by showWidth() shows '200px'. So, I have two questions: 1. Why? 2. Is there a way of accessing these external style elements without having to define styles inline all the time? Cheers! Mike hi , how to load external page into div without template . Example : I have external page using CSS & html : <div id="header"></div> <div id="content1"></div> <div id="content2"></div> <div id="content3"></div> <div id="sidebar"></div> <div id="sidebar1"></div> <div id="footer"></div> NOTE : all javascript code load external page with all template code into div ! how to load ONLY content2 into DIV . thanks Hey all, I'm fairly new to JavaScript. I learned PHP and now I'm creating a user registration and login system for an application I'm making and I decided I wanted to give JS a try. I'm trying to make a form validation function that will be called when I press the submit button on the form but I want to use an external js file to store all my custom functions. I have the OnClick event in the button with the call to my function inside of that. But where and how on the page to I reference my external file so that the button can call the function? Thanks guys! Dear Forum, I have a website of quite a few pages which also has a style sheet switcher so the user can select their own customised graphics and layout (css file) these css files load in the graphics but only when the call is clicked... even if the page has already been opened for seconds or minutes when the graphics could have been loaded in for an instant switch. so i implemented the following code: Code:
<SCRIPT language="javascript">
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
</SCRIPT>
<body onLoad="MM_preloadImages('/corporate/heading.png','/creative/heading.png','/earth/heading.png','/under-the-sea/heading.png','/space-and-stars/heading.png','/classical/heading.png','/corporate/document.jpg','/space-and-stars/document.png','/creative/document.jpg','/earth/background.jpg','/under-the-sea/background.jpg','/classical/document.png','/classical/background.jpg','/under-the-sea/document.png','/corporate/home-graphics.png','/earth/content.jpg','/earth/footer.jpg','/earth/home-graphics.png','/under-the-sea/home-graphics.png','/creative/home-graphics.png','/space-and-stars/background.jpg','');">
it works fantastically - you open the page and as long as it takes to notice where you can click the styles is the same amount of time it takes to have the styles cached for the styles switch immediately and effortlessly. however, the site has grown and is now quite a number of pages with the above in each html file. ive just added a "creative 2" style, which has caused the above to need updating........ the maintenance of this code is inefficient to edit each page. would someone be able to point or show me how to, in principle: Code: <body onLoad="MM_preloadImages('/styles-code.js);">
styles-code.js?? page:
'/corporate/heading.png',
'/creative/heading.png',
'/earth/heading.png',
'/sea/heading.png',
'/classical/heading.png',
'/corporate/background.jpg',
'/creative/background.jpg',
'/earth/background.jpg',
'/sea/background.jpg',
'/classical/background.jpg',
etc
and have 1 page of this code called in by all pages in an easy to see and edit list? would really appreciate guidance with this, |
