JavaScript - Go To Top Arrow Following Page
I've seen websites that have things like feedback and an arrow facing up that either take you to the top of the page or opens a form to give your feedback.
Similar TutorialsI have three buttons on a typical page (sample page: http://jimoberst.com/paintings/p18.html). One goes to the previous page, one to the next, and one up a level. Can I link these buttons to 3 arrow keys to simplify navigation for the user? I thought this would be a common task, but I cannot find any canned code on the web to do it. I can code simple html, but don't know javascript. Thanks!
I want to use an onkeydown() on my web site and the web site to know which key I pressed. Specifically know I pressed the arrow keys and store which key was pressed in a variable. any help? must work on all browsers. Hey! I searched a while on the web for this but i didn't find a solution that really worked. So is there a way how i can prevent IE9 from scrolling when i use the arrow keys? hi everybody; i'm using this code to trigger functions with left and right arrow keys.. but they work even if the arrow keys pressed in input boxes.. is there any way to prevent this code to work when user presses the arrow keys in input boxes? Code: document.onkeydown = function(evt) {
evt = evt || window.event;
switch (evt.keyCode) {
case 37:
geri();
gostergeyaz();
break;
case 39:
ileri();
gostergeyaz();
break;
}
};
Disable Arrow Keys I am creating an online flash gaming site, Aaron's Game Zone: http://azzaboi.weebly.com Some of the games on it use the arrow keys, however IE also uses them to scroll the page. I am learning JavaScript and am trying to write some script to pervent the page scrolling up and down while playing a game. For example... Guardian Rock uses the arrow keys to slide around, at the same time the page scrolls. http://azzaboi.weebly.com/guardianrock.html Here is the script I've tried to write to pervent the scrolling: Code: <script type="text/javascript">
function KeyPressHappened(e){
if (!e) e=window.event;
var key=e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
if(key == 37 || key == 38 || key == 39 || key == 40)
{
e.preventDefault();
return false;
}
return true;
}
document.onkeypress = KeyPressHappened;
</script>
There's a bug in it or it's not correct, no error message given, could anyone point out the mistake please? Hello. I want to move something with the arrow keys, but some aprt of script is incorrect and it's not working Code: </style>
<script type="text/javascript">
function setup() {
row=0;
col=0;
imageSnake(row,col);
}
</script>
</head>
<body onload="setup()" onkeydown="handleKey(event)">
<center>
<script type="text/JavaScript">
document.write('<table border="1" cellspacing="0" cellpadding="10">')
var count =0
for (var row=0; row<20; row++) {
document.write('<tr>');
for (var col=0; col<20; col++) {
document.write('<td style="border:0"; id="count++";>');
document.write('</td>');
}
document.write('</tr>');
}
function handleKey(e) {
if (e.type == 'keydown' && (e.keyCode == 27 || (e.keyCode >= 37 && e.keyCode <= 40))) {
switch(e.keyCode) {
case 37:
dC = -1;
dR = 0;
break;
}
emptyCell(row,col);
function emptyCell
var id = 'r' + r + 'c' + c;
var cell = document.getElementById(id);
if (cell) cell.innerHTML='';
}
row += dR
col += dC
function insertImage(r,c) {
var id = 'r' + r + 'c' + c;
var cell = document.getElementById(id);
var color = cell.className;
if (color != 'white') {
var image = 'img.gif';
}else{
var image = 'img2.gif';
}
cell.innerHTML = '<img src="" + image + alt="" + color + 'image' />';
}
</script>
Thank you for any noticed error. I have a search box on my website, that gets users from my database using php. And uses Javascript to display suggestions as the users type. What I'd like to be able to is to use the arrows to toggle down through the different suggestions. Any ideas how I would go about doing this? Here's the javascript part of the code: Code: function createObject() {
var request_type;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){
request_type = new ActiveXObject("Microsoft.XMLHTTP");
}else{
request_type = new XMLHttpRequest();
}
return request_type;
}
var http = createObject();
/* -------------------------- */
/* SEARCH */
/* -------------------------- */
function autosuggest() {
q = document.getElementById('search-q').value;
// Set te random number to add to URL request
nocache = Math.random();
http.open('get', 'lib/search.php?q='+q+'&nocache = '+nocache);
http.onreadystatechange = autosuggestReply;
http.send(null);
}
function autosuggestReply() {
if(http.readyState == 4){
var response = http.responseText;
e = document.getElementById('results');
if(response!=""){
e.innerHTML=response;
e.style.display="block";
} else {
e.style.display="none";
}
}
}
Hi All, I have a javascript scrollbar in the middle of the webpage, with two images as arrow at both end. Onclick of up and down arrow images the inside content moves up and down respectively. All works fine. What I need is, when I scroll down the down arrow should be disabled or invisible (as there is nothing to scrolldown) and same way when the content is at the top, the up arrow should be disabled or invisible.

My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer he The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script> About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to. When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00. I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top. I appreciate your help. I just wrote an essay to discover it had logged me out and I lost everything. Grrrrrrr. Here goes again, simplified this time. I've got a sticky footer at the bottom of the page and a spry collapsible panel which expands to reveal content on mouse over. The problem I'm facing is that the page doesn't scroll down with it, only the scroll bar gets larger to accommodate for a manual scroll down. This is kind of useless because the user might not even realise that there's extra content there in the first place if it's not automatic. My question is, what's the best javascript code to use to automatically scroll the page down when the spry tab is opened and where would I insert it? I've tried all morning with no success so far! Thanks, Nick, I'm copy pasting this post this time round, I don't trust this website now I want to implement a javascript function where a submit button will be submitted from the parent page each time I close a child page. Please let me know what I did wrong in my code and please elaborate your answer so that I could understand it better. Thank you so much for your help. I have the following jscript code but it is now working. Code: window.onunload = submitParent;
function submitParent()
{
var doc = window.opener.document,
theForm = doc.getElementById("finalForm");
theField = doc.getElementById("finalSelected");
theForm.submit();
theField.trigger('click');
}
My form from the parent page is as follow. I want my jscript to just click on the submit button once. Code: <form id = "finalForm "name= "finalForm" method="POST" action=""> <input type="Submit" id = "finalSelected" name="finalSelected"/> Hi, I am Aditya. I am explaining below the exact scenario where I need the help: I am developing a web application in which I need to integrate a javascript/html editor on some of the web pages and then provide 'Edit' buttons on those web pages so that users can edit the content on that partciular html/jsp page (like editing in wiki pages) and then, when they add some content and click on submit button, the new content should appear on the web page with all the formatting (i.e. bold, italics, color and so on) which was applied by user when he was entering the text. Now, I need help for the below issues: 1. Please suggest me a good javascript/html editor (freely downloadable) which I can use to integrate with my web pages. 2. Once the user has entered some content using the above javascript editor, how to make that content reach the server and update the corresponding web page. I am new to web development, so may be that these questions are too simple. But, I need some help from you. Waiting for your reply, Thanks, Aditya Hi there! I am using GlassBox "http://www.glassbox-js.com/" As a light box on a website. Basically, You click an thumbnail image, and a window pops up with a larger version of that image. Now originally, the window opened X number of pixels from the top of the page. However, My thumbnail images were located mid page, so when you clicked on one, the window would open at the top of the page and the user would not see it unless they scrolled up. So I attempted to modify the script so that it would get the users page width/height and display it directly in the center no matter the position. Now my problem is that the script only works when the user has already scrolled down. So if the page is scrolled all the way to the top, and you click on a thumbnail, the window will not open center screen. Here is an example: http://synaxis.pcriot.com/ When the page loads, DO NOT scroll it, and click on the image. You will see the window pop up, and not centered, like it should be. However, now if you scroll down, and click the image again, you see that it is now centered. I also noticed that when the page is scrolled up, and the image does not center, it always is placed below the thumbnail image, or otherwise where ever the DIV is located. It normally located under the image, but if i place the DIV at the top of the page then the window will pop up there. And this does happen on every browser that I have tested, Firefox, IE, and Chrome. So, I am pretty much stumped as to why this is happening. If anyone can shed some light I would be very grateful. Thank You Here is a link to the original code: http://synaxis.pcriot.com/javascript...ox/glassbox.js And modified code: http://synaxis.pcriot.com/javascript...ox/glassbox.js The modified code is at the very bottom of the script. Original Code: Code: /**
* @public
*/
if ( typeof($) == 'undefined' ) {
$ = function (id) {
return document.getElementById(id);
}
}
Modified Code Code: /**
* @private
*/
var removeElement = function(id) {
var Node = document.getElementById(id);
Node.parentNode.removeChild(Node);
}
/**
* @private
*/
var getDocHeight = function() {
var db = document.body;
var ddE = document.documentElement;
return Math.max(
db.scrollHeight, db.offsetHeight, db.clientHeight,
ddE.scrollHeight, ddE.offsetHeight, ddE.clientHeight
);
}
/**

It is possible to perform a find in page search that looks at a specific link, opens the page in a new window and finds the text within that document?? Basically I regularly use an html page in work that has a list of people and their telephone numbers. I want to be able to type in a searchbox on my main page and it open the target page and find the name I am looking for? Is this possible or can you only Find In Page on the same page or another frame? Tearing my hair out........ Thanks Glen |
