JavaScript - How To Disable Up/down Arrow Keys In Mozilla Firefox Browser Useing Javascript
Similar TutorialsDisable 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? 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;
}
};
On http://kisa.ca/cc/ I'm using JQuery's .keydown() to grab arrow keys. http://pastie.org/938572 But my friends using Linux are unable to use arrows to play the game: http://alteeve.com/files/cc.png Halp? 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";
}
}
}
I 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 am trying to assign the left and right arrows, but I cannot get the code to work. It would be great to get some help--I am a newbie to coding. <html> <head> <script language="javascript" type="text/javascript"> document.onkeydown=function(e) { var thelink if (e.keyCode==37) thelink='prevlink' else if (e.keyCode==39) thelink='nextlink' else return document.location.href=document.getElementById(thelink).href} </script> </head> <body> <a href="#" onkeydown="return previous(this)" id="prevlink">PREVIOUS</a><br /> <br /> <a href="#" onkeydown="return next(this)" id="nextlink">NEXT</a> </body> </html> Hi All, This is my first post in this forum. I am relatively new to javascript. Hope I get some guidance here. Also I would like to contribute here when I get little expertise on javascript. I have developed following snippet of code, which is working very well with firefox 6.0. But when it comes to IE 8.0, it just does not work. Quote: <SCRIPT LANGUAGE="JavaScript"> function refreshFrame() { frames['top'].window.location.href = "report.php?parent_id=<? echo $parent_id; ?>"; } </script> </head> <? include('style.php'); include('PHP_functions.php'); print(" <FRAMESET rows='96,100' onLoad=refreshFrame() BORDERCOLOR=blue BORDER=0> <FRAME SRC=blank.html SCROLLING=NO NORESIZE NAME=top> <FRAME SRC=manage.php?view=show_all&parent_id=$parent_id NAME=bottom> </FRAMESET> "); ?> </HTML> In the above script, I am trying to load the frame top after loading frame bottom, as the latter takes more time to load due to some processing involved. Till frame bottom is under processing stage, I display a message "Processing Please wait" which is coming from blank.html. Working under Firefox: It loads blank.html first and displays the message as "processing please wait". Once frame bottom has completed the processing it displays its contents at second half of the webpage. Then finally frame top gets loaded on first half of the web page. This is the expected result. Here URL does not change as the URL remains same as before "http://xyz.com/index.html" Not Working under IE It loads blank.html first and displays the message as "processing please wait". Once frame bottom has completed the processing it displays its contents at second half of the webpage. Then finally frame top gets loaded on whole page instead of first half of the page. Here URL changes to complete new URL as "http://xyz.com/report.php?parent_id" Can anyone please suggest what could be reason for this. Thanks, Vinay 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. Please help...

What I'm supposed to do is to get the values and update them automatically to the database. I'm actually using HtmlUnit to do this project, and I've heard how I can use getElementById() to get the values. But I don't know how to start. I'm a beginner so I might need a lot of help on this matter. Help is kindly appreciated. Thanks. Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks Is it possible to disable all scripts within a certain div? Like if I was displaying something in <div id="member"> and a member posts a script within that div, I would like it to not work.
Greetings, I am currently using the websites tutorial about browser detection using the navigator. http://www.javascriptkit.com/javatutors/navigator.shtml I am however finding myself unable to detect a pattern in order to learn from. My aim is to use Browser detection to have a CSS file for each browser type, such as Firefox, IE, Opera, Safari and then an overall CSS file if none of the above, to fix numerous flaws. For IE and Firefox using the site's code is all well and good and while I haven't tested it yet I'm wondering how to set up the coding so that it can detect a safari browser. There are lots of slashes and d's and brackets and I do find myself unable to understand their purpose. So if someone can explain how I could do it for Safari I would be very appreciative. Is there a way to use inline javascript that will prevent any javascript after it (in the same page) from executing? So, for instance I could have something like: -Content- -JS A- -Content- -JS B- -JS C- 'JS A' would execute, 'JS B' would be the code I'm asking about and it would cause 'JS C' to not do anything. Sorry if this is an off-the-wall question. I good with C/C++, VB, Ruby, Lua, HTML, etc, but I haven't gotten to Javascript (or Java) yet so I have no idea what the capabilities or environment setup are like. Thanks in advance for any advice. I have a server that when restarted emails from the code below every single time. I would like to know what I can use in the code below to regonize the restart and bypass the email send piece in BOLD below. Any help will be greatly appreciated. now = currentDateTime() if (statusInOverride != lastOverrideValue) or (overrideTime != lastOverrideTime) lastOverrideValue = statusInOverride lastOverrideTime = overrideTime if statusInOverride.value == true overrideStopTime = now overrideStopTime.minute = now.minute + overrideTime // Also send an email overrideHours = overrideTime / 60 mailSend(address, suiteName + " Overridden", suiteName + " has been overridden for " + overrideHours + " hours."); else mailSend(address, suiteName + " Override Canceled", suiteName + " has canceled their override. There was " + remainingTime + " remaining."); remainingTime.duration = 0 endif endif if statusInOverride.value == true remainingTime.duration = delta(now, overrideStopTime) endif Hi, I have two buttons save and finish. I want to enable the button finish whenever I click the save button. page1.jsp. <script> InitialLoad() { document.getElementById('finish').disabled = true; } save(){ document.getElementById('finish').disabled = false; } </script> <html> <body onload= "InitialLoad()"> <input type="submit" name="finish" id=="finish" value="finish"> <input type="submit" name="save" value="save" onclick= save();> </body> </html> strutsconfig.xml <forward name="success" path="atre.dodUpgrade.show.page1"/> Using the above I can enable it temporarly. But whenever I call the forward page it on action class forward = mapping.findForward("success"); The Problem is page Refresh again and it shows disabled button for finish. what could be the solution for this? Thanks Hello, I have a question what is the best way to identify a browser, browser version and OS in javascript. I have try a few scripts but they all fail. This will help me out formating the code for diferent browsers. Thanks Hi I have a quiz that uses javascript to calculate the scores over 10 pages of a template which uses jquery. I'm having trouble disabling the navigation buttons so that the user cannot move on until they submit the question. The code is in Jquery and Javascript and i'm still learning. I tried this which worked as it stopped them from navigating away from the page but it stopped my quiz from calculating the score too.... Code: //Next Page Function
$('.next').click(function() {
if (current_page == no_pages){
//do nothing
}
else{
if (flag==false)
{
try {
checkAnswer(document.getElementById('quizForm'))
flag=true;
return false;
}
catch(err)
{
if (err.number !=-2146823281)
{
alert(err.description);
}
}
}
next_page = (current_page + 1);
$("#content").fadeOut("slow",function(){
$("#content").load("pages/page_" + next_page + ".html").fadeIn('slow')}
);
current_page ++;
$("#current_page").html(current_page);
progress_bar();
}
});
This is what the code looks like now without the changes.... Code: //Next Page Function
$('.next').click(function() {
if (current_page == no_pages){
//do nothing
}
else{
next_page = (parseInt (current_page) + 1);
$("#content").fadeOut("slow",function(){
$("#content").load("pages/page_" + next_page + ".html").fadeIn('slow')}
);
current_page ++;
$("#current_page").html(current_page);
progress_bar();
}
});
I was also told to try and disable the button until they click sumbit and then enable it straight away but i'm not really sure what i'm doing. I put this bit together but it doesn't do anything.... Code: else{
if (document.getElementById('quizForm')){
if (document.quizForm.cc.disabled==true)
document.quizForm.cc.disabled=false
else
{return true;}
Any advise? Thanks. hello Guys , Well, i've a BIG Problem With a HUGE JS application , i'm modifying its javaScript code to work on both IE/Mozilla , currently it works fine on IE but not on Mozilla. My main Point now is events. lets try with a little module, consider this function : Code: function HiliteLectures(Group,Alternatives,ForeColor){
var i,Lecture,EventLecturesGroup,EventLecturesAlternatives,LecSrcElement
//validate event source
if (event.srcElement.id=='Animate'){LecSrcElement=event.srcElement.parentElement}else{LecSrcElement=event.srcElement}
EventLecturesGroup = Group.split(",")
EventLecturesAlternatives = Alternatives.split(",")
//hilite Lecture Group with Red as sections
for(i=0;i<EventLecturesGroup.length;i++){//if item is not selected
Lecture=document.getElementById(EventLecturesGroup[i])
if ((EventLecturesGroup[i]!='') & (Lecture!= null)){
Lecture.style.borderColor='red';
Lecture.style.borderWidth=2
if (Lecture.style.zIndex != 1000){Lecture.style.zIndex=120} //skip obligatory zIndexes
}
}
//hilite Lecture Alternatives with blue as Lectures
for(i=0;i<EventLecturesAlternatives.length;i++){//if item is not selected
Lecture=document.getElementById(EventLecturesAlternatives[i])
if ((EventLecturesAlternatives[i]!='') & (Lecture != null)){
if (EventLecturesAlternatives[i]!=''){
Lecture.style.borderColor='blue';
Lecture.style.borderWidth=2
if (Lecture.style.zIndex != 1000){Lecture.style.zIndex=120} //skip obligatory zIndexes
}
}
}
//Put the current lecture forecolor to ForeColor
LecSrcElement.style.backgroundColor=ForeColor;
}
and it is attached in this place like : Code: temp.onmouseover=new Function("HiliteLectures('"+Lecture.Group+"','"+Lecture.Alternatives+"','"+Day.HiliteColor+"');")
this works fine in IE , i want to modify it to work on Mozilla , Any Help ?? |
