JavaScript - Linking To Anchor Near Bottom Of A Page
. . . .Within my website (so I control all pages) I often make anchor-links from one page (call it currentpage.htm) to an anchor-link in another page (newpage.htm). Imagine that newpage.htm has two anchor-locations, one near the page-beginning (#high) and one near the page-end (#low).
. . . .There is a problem when linking to newpage.htm#low (or an inside-the-page link to #low) because the page-end goes to the bottom of the browser window, and the location (#low) appears somewhere in the vertical middle of the browser window, so it's difficult for a user to know where they should begin reading, and they get confused. . . . .A low-tech solution is to "make the page longer" by adding space to the page-bottom with a series of <p> </p>, or with a tall blank spacer-gif. But this implies something false, it tricks a user into thinking the page is longer than it is, so they may think "this page is too long, I don't want to read that much" and they go away, or they "skim" when they could read more slowly. . . . .Is there a solution using javascript? . . . .If yes, I assume the javascript must be located within newpage.htm, because a command within currentpage.htm can't "tell another page" what to do. Is this correct? I'm not confident because I'm a novice with using javascript. . . . .So is there a way to say, within newpage.htm, "make the page longer by adding a blank spacer-gif to the page-end when an incoming link goes to newpage.htm#low" but to have this be temporary, so when newpage.htm is opened the next time normally (with a link to newpage.htm or to newpage.htm#high) the spacer-gif is gone? CraigR Similar Tutorialshi, I have a large list of UK towns, see he http://www.mypubspace.com/mobile/index.php#towns I would like to add an a-z link so that when a user clicks on say 'W' they are then presented with the towns that begin with 'W' the problem is, is that I have to keep #towns in the URL as it's a web application Can anyone help? thanks This code: when you click a link it jumps to an anchor point on the page and scrolls there smoothly. I was wondering how I get the same effect if I want the link to jump to another page? A normal anchor point on another page would set the href to, for instance, 'index.html#contact' but it won't work in this case as the javascript isn't reading the '#'. Any ideas?? Code: <script type="text/javascript" src="jquery.js"></script>
<script>
function goToByScroll(id){
$('html,body').animate({scrollTop: $("#"+id).offset().top},'slow');
}
</script>
</head>
<body>
<ul>
<li><a href="javascript:void(0)" onClick="goToByScroll('contact')">Go to anchor 1</a></li>
</ul>
Hello Everyone!!! I have a question, and any advise or help would be greatly appreciated.

One for the visibility function: Code: <script type="text/javascript">
function toggle_visibility(id) {
var e = document.getElementById(id);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
</script>
The other for changinging the image to reflect the text box's status (open of closed): Code: <script type="text/javascript">
var ImgPath='../images/portfolio/';
function changeImage (id) {
var tab = document.getElementById(id);
if (tab.src.match('open.png')) {
tab.src = ImgPath + 'close.png';
}
else {
tab.src = ImgPath + 'open.png';
}
}
</script>
The problem only shows further down the page, when I click to open a box it automatically goes back to the top of the page instead of staying at the user's current page position I would like it to stop changing the page position onclick. Any help would be much appreciated! Hi I have created a very very simple javascript that displays random text quotes. It is in Greek but here it is anyway: http://gerogriniaris.blogspot.com It is in blogger and shows up as a gadget. My problem is that i need to make it reload by a button and at the same time go to the top of this gadget (using an anchor). The reason I want to do this is that I have been sharing this with other bloggers, but if they don't put it on top of their page, as soon as they press the button that reloads the page, they are in the top of the page and they would have to scroll down to find the quote. I have tried to use window.location.reload with window.location.hash. It works in Firefox, but not in IE. I have been trying something like that: Code: <input type="button" value="Click to refresh" style="width: 130px" onclick="window.location.hash='#something';window.location.reload()" /> As i said, this works with Firefox, but not with IE9 Also, I can't define urls beforehand because I want other people to be able to use it to their own blog or website. I suppose this is a noob question, but I have been trying to find a solution and couldn't. Please be kind... Any ideas? Hey, I have 3 bits of code, 2 of which I'm pretty sure are right [i know the php works, and the ajax looks fine], but one i'm having trouble with. Basically what I'm trying to do is use a link to call php function [calls a piece of text from a database]. Which worked fine. But then I tried to incorporate AJAX into the script to make change dynamically on the page, and I'm a little confused with it all. I've got the AJAX and PHP, [and an attempted page with a link on to try and call the function with AJAX] but so far it's not doing as it should. Wondered if anyone could show me where I'm going wrong with the whole 'linking together' thing? So far everything I've tried hasn't worked. [hope this doesn't violate the forums 'don't dump your code' rule. But it's kind of all necessary] The AJAX [AJAX.js]: Code: function loadurl(generate.php) {
var ajax = false;
// Create the object:
// Choose the objecttype, depending on what is supported:
if (window.XMLHttpRequest) {
// IE 7, Mozilla, Safari, Firefox, Opera, most browsers:
ajax = new XMLHttpRequest();
} else if (window.ActiveXObject) { // Old IE-browsers
// Make the type Msxml2.XMLHTTP, if possible:
try {
ajax = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e1) { // Else use the other type:
try {
ajax = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e2) { }
}
}
// Retrieving the data from the page
if (ajax) {
alert("url:generate.php" + url);
ajax.open('GET', url);
// Sends request
ajax.send(null);
// Function that handles response
ajax.onreadystatechange=function(){
// If everything is OK:
if ( (ajax.readyState == 4) && (ajax.status == 200) ) {
// Returns the value to the document
alert(ajax.responseText);
}
}
} else { // AJAX is not useable
alert('It is not possible to connect, please update your browser.');
}
}

I've included the file names with extensions just in case it's something to do with those, but thanks in advance for any help. Greatly appreciated. I have a simple script that will get the NWS forecast for any zip code and it opens it in a new tab. I would like it to open in an iframe on another page with in my website. I have come close, but not quite all the way yet. This will enter the forecast in an iframe on the same page as the input form. http://www.cavecountryweather.com/wxsearch.php How can it load onto this page from the form on the menubar? This menu is common on all the sites pages. I have seen solutions posted around the internet using javascript for similar issues, but I haven't been able to get any to work in my situation. My javascript skills are - none. Any help would be appreciated. i have been looking all over the web and i can't get to where i need to be to finish my page. basically i have two pages and if someone clicks a specific link from the first page i want it go to the other page but load a specific page in the iframe on the second page. i know how to use javascript to make a specific page load into an iframe but not how to make the page load into the iframe on another page. all i need to know is how to do it for one page then i think i can build the decision structure around it to make it work for more than one link (hopefully). any help will be greatly appreciated. thanks. Hi guys, Having a little bit of trouble with a site I'm currently working on... I'm using some AJAX for the instant g-mail/facebook style navigation, you know the kind, with no refreshes, etc. Problem is, to allow for back/forward and bookmarks, I currently use a URL that looks like: http://www.mySiteOfFun.com/index.html#page=news.html; This is fine, not a problem... The issue comes into play when I want to open up the news.html page, from my home.html page, and have it open to news item #6 (for example). I can't add a #, because one is already being used to reference the anchor for the content div. Has anyone run into a similar problem before? If so, how did you resolve it? Can some jQuery be used to find the location of the news item div in question, on load, and scroll to it like that? Just not sure how to progress really, and any help would be greatly appreciated! Hello Basically I have found and adapted the code: Code: alreadyloading = false;
nextpage = 2;
$(window).scroll(function() {
if ($('body').height() <= ($(window).height() + $(window).scrollTop())) {
if (alreadyloading == false) {
var url = "page"+nextpage+".html";
alreadyloading = true;
$.post(url, function(data) {
$('#projectscontainer').children().last().after(data);
alreadyloading = false;
nextpage++;
});
}
}
});
I want when the user scrolls to the bottom of the page for content in a new page to load under the div "#projectscontainer". So in the new page 'Page2.html" I have put 5 divs going down with content in... I want the new content to appear below "#projectscontainer'" Why won't this work? Anyone know? Thanks I've searched everywhere for help on how to do this... I have a website for tanning salon services. Salon A's page has links for 4 possible equipment choices -[I] (diamond, platinum, gold, bronze levels) on the Sunbeds page. Sunbeds page has 2 iFrames, top and bottom, that are changed by 4 functions - changediamond(), changebronze(), etc. based on the selection. I need to be able to click a link on the Salon page that will take me to the corresponding function on the Sunbeds page... Here's what I have so far: Salon A page Code: <a href="sunbeds.htm?javascript:changediamond()"><img src="images/nr_diam_sm2.jpg" alt="Diamond Level Sunbeds" /></a>
(thru)
<a href="sunbeds.htm?javascript:changebronze()"><img src="images/nr_brnz_sm2.jpg" alt="Bronze Level Sunbeds" /></a>
Sunbeds page Code: <SCRIPT language="JavaScript">
function changediamond()
{
parent.FRAME1.location="sb_top_ct1.htm";
parent.FRAME2.location="sb_bot_ct1.htm";
}
(thru)
function changebronze()
{
parent.FRAME1.location="sb_top_ct4.htm";
parent.FRAME2.location="sb_bot_ct4.htm";
}
</script>

<a href="javascript:changediamond()"><img src="images/diamond_sm2.jpg" alt="Diamond Level Sunbeds" /></a>
(thru)
<a href="javascript:changebronze()"><img src="images/bronze_sm2.jpg" alt="Bronze Level Sunbeds" /></a>
The links take me to the correct page but not the function. Once I'm there I can select the functions and the iFrame change works great. I'm just at a loss for passing along the data string ie sunbeds.htm?javascript"changediamond() I would certainly appreciate any help and advice you could share. I'm sure it's pretty simple but for a JS newbie, it's frustrating! hello i've followed this javascript and i'd like to link the text to one of my page.How do i place the ahref tag in the script.Appreciate your help http://www.javascriptkit.com/script/script2/neontext.shtml Im looking for a script to show a sliding popup from bottom right to upward direction after the page is loaded with a close button to.
hello i use this script, and its working so far. except i want the element to stick to the bottom not the top.. http://javascriptkit.com/javatutors/static3.shtml i am a absolute java-noob and if anyone has a hint for me, i would be happy i already tried to rename some words to bottom, but this doesnt work (ie iebody.scrollTop to iebody.scrollBottom) thanks a lot, regards florian I am trying to use these two js codes in one page: http://acrisdesign.com/2010/03/jquer...on-hoverclick/ http://www.huddletogether.com/projects/lightbox2/ They both work perfectly fine except when both linked up at the same time. Only the last one will work. I've tried to find how the codes are working when the page loads in order to fix that problem but I cant figure it out for these two specific codes. Thanks. I've been handed an html document that contains a centered, scrollable <iframe> element with a static height and width. This iframe element displays a simple html document that houses the 'terms of service' text. Their goal is to have it to where the <a href> link at the bottom that is shown to the user as 'next' is disabled until the user scrolls to the bottom of the terms of agreement box. The clickable link could be a button, image or text (no preference). They have to have it this way for legal reasons and radio buttons or checkboxes will not suffice unfortunately. Question: What is the best way to go about doing this that seems to be cross-browser friendly (especially IE7). I offer $10 via paypal for well commented method/script. Hello , here is my code(which is not working on my problem) i want to remove anchor tag(href="a") will u please help.... Code: <html>
<head><title>Welcome to DevForum</title></head>
<script language="javascript" type="text/javascript">
function Remove()
{
var anchor = document.getElementsByTagName("a");
var i;
for(i=0;i<anchor.length;i++)
{
var anc=anchor.item(i);
var href=anc.attributes.getNamedItem("href");
if (href.value == "a")
{
anchor.item(i).attributes.getNamedItem("href").value = "";
}
}

Thanks in Advance.... Hey guys I am currently trying to set up a set of <li>'s to act as links just so: Code: <li onmouseover="location='http://www.google.com'">Text</li> Obviously this works fine, however what I need it to do is load in an iframe rather than reloading the browser. So the question is, what code do I need to get target data in to the js? Thanks! Please could anyone offer any advice, in simple terms on how to add anchor points to a page in order to create a smooth scroll element such as this one: http://www.kryogenix.org/code/browser/smoothscroll/#top Any help would be much appreciated. greetings everyone! this is my first time trying to join this javascript community. Well then, now I'm telling about my miss-understanding of this keywords of javascript here... here's the html Code: <fieldset > <legend>Attachment</legend>
<table id="attachment" style="height: 50px;" width="200" border="0">
<th width="19%">Title</th>
<th width="26%">File</th>
<th width="41%">Description</th>
<th width="6%">Upload</th>
<th width="6%">More File</th>
<tr>
<td><input name="title" type="text" value="- none -" size="33" maxlength="50"></td>
<td><input name="filepath" type="file" size="33"></td>
<td><input name="description" type="text" value="- none -" size="60" maxlength="200"></td>
<td><input name="upload" type="button" value=" Upload " onclick="upload(this)"> </td>
<td><div align="center">
<input onclick="addMoreFile()" type="button" value="+">
</div></td>
</tr>
</table>
<!-- end Attachment --> </fieldset>
the aim is that the upload button would eventually changed into image and then changed back to a link. That one is already done here's the javascript Code: var attRow;
function upload(obj){
// obtain the table pointer
var attTable = document.getElementById('attachment');
// post file into the jsp file
// changing the image
// get parent pointer of this element
var par = obj.parentNode;
var loImage = document.createElement('img');
loImage.setAttribute('src', 'images/loading1.gif');
par.innerHTML = '';
par.appendChild(loImage);
// create the removal link
var text = document.createTextNode('remove');
var liRem = document.createElement('a');
liRem.setAttribute('href','javascript:removeFile(this)');
liRem.appendChild(text);
par.innerHTML = '';
par.appendChild(liRem);
}
function removeFile(obj){
// post fileid
// change the image
}
function addMoreFile(){
// create fully file upload row
// consist of two text elements, file element, and 1 button.
var nFileTitle = document.createElement('input');
nFileTitle.setAttribute('name','title');
nFileTitle.setAttribute('type','text');
nFileTitle.setAttribute('size', '33');
nFileTitle.setAttribute('value','- none -');
nFileTitle.setAttribute('maxlength','50');
var nFilePath = document.createElement('input');
nFilePath.setAttribute('name', 'filepath');
nFilePath.setAttribute('type', 'file');
nFilePath.setAttribute('size', '33');
var nDesc = document.createElement('input');
nDesc.setAttribute('name', 'description');
nDesc.setAttribute('type', 'text');
nDesc.setAttribute('value','- none -');
nDesc.setAttribute('size', '60');
nDesc.setAttribute('maxlength', '200');
var nUpButton = document.createElement('input');
nUpButton.setAttribute('name', 'upload');
nUpButton.setAttribute('type', 'button');
nUpButton.setAttribute('value', ' Upload ');
nUpButton.setAttribute('onclick', 'upload(this)');
// empty element
var ksg = document.createTextNode(' ');
// obtain the table pointer
var attTable = document.getElementById('attachment');
attRow = attTable.rows.length;
alert(attRow);
var nextRow = attTable.insertRow(attRow);
var ceL = nextRow.insertCell(0);
ceL.appendChild(nFileTitle);
ceL = nextRow.insertCell(1);
ceL.appendChild(nFilePath);
ceL = nextRow.insertCell(2);
ceL.appendChild(nDesc);
ceL = nextRow.insertCell(3);
ceL.appendChild(nUpButton);
ceL = nextRow.insertCell(4);
ceL.appendChild(ksg);
}
the problem arise when I try to use the removeFile() function using this keywords. into these; Code: function removeFile(obj){
// post fileid
// change the image back
// get parent pointer of this element
var par = obj.parentNode;
var loImage = document.createElement('img');
loImage.setAttribute('src', 'images/loading1.gif');
}
I try to apply the same approach as the upload() function. But instead the this object which is pointing at the parent node seems unreliable. Is there any missing point i haven't observed? |
