Thanks! x hi all i'm kind of new to the JS world and need your help with some thing i hope it not that big to ask. if you go to linkedin website with your user (www.linkedin.com) you will see a bar called LinkedIn Today. what i need is this kind of bar but with messages changing all the time(moving) is this some thing i need to write from scratch or there some example that i can use? any help will be good for me now because i need to do it ASAP regards,shay I have a slideshow that goes through pictures once you click on the Play button and doesn't stop until you press on the Stop button. How can I make it so that it automatically plays once the website loads without having to click on the Play button? Heres the code: Code: <div class="tabs png"><span class="tabs-inner"><a href=""></a> <a href=""></a> <a href=""></a> <a href=""></a> <a href=""></a> <a href=""></a> <a href=""></a></span></div>
<div class="slider-indent-button">
<a href="#" onClick='$("div.tabs").tabs().play();'>Play</a>
<a href="#" onClick='$("div.tabs").tabs().stop();'>Stop</a>
</div>
All help is much appreciated!!! I'm quite new to JavaScript, but I wanted to add a feature to a sample website that I need to have done by tomorrow night. I have two HTML paragraphs which I will call "a" and "b". Below those paragraphs I have a text box and a submit button. This is how I declared them in the HTML doc: Code: <input type="text" name="message" value="Blank Message" id="newsmessage" /> Code: <input type="button" value="Post" id="submitbutton" onclick="updatepost()" /> Now when I click the submit button I want paragraph b to replace itself with paragraph a, and I want paragraph a to replace itself with the text in the text box. Here's the JavaScript that I have written. (I'm aware it's probably quite off.) Note: paragraph a is toppost, paragraph b is bottompost, the text box is named message, and I created p1 and p2 as temporary holders for the strings. Err... variables. Code: <script type="text/javascript">
function updatepost()
{
p2=document.getElementById("toppost");
document.getElementById("bottompost").innerHTML=p2;
p1=document.message.elements[i];
document.getElementById("toppost").innerHTML=p1;
}
</script>
As of right now the paragraph a holds the text "a" and paragraph b holds the text "b". When I click post paragraph a still reads "a" and paragraph b reads "[object HTMLParagraphElement]". Sorry for my minimal JavaScript knowledge; I have full intentions of fully learning the language quite soon. I just wanted to implement this feature in a site that I had to create and my deadline is tomorrow. Thanks guys! -Dave I am working on a site for an online radio station and I want an external player to launch on site visit and to continue playing as the visitors surf my site. I feel I am 95% there as I have the player spawning on launch and checking for popup blockers. If a popup blocker is found the user is prompted to add my domain to their allowed lists so that future visits will launch the player right out of the box. My problem is this. When someone navigates back to the "home" page (where the script is located the external player window reloads and I do not want it to. I have found a couple of sites that say do this and that but I am a 100% novice at javascript and can not figure it out. here is the url of the site I am building http://www.radiotrips.com/czmradio - If you have popup blocker on you should get an alert. If not a small player should launch here is the code that I am using to spawn the external player and check for popup blockers ************** <script language="javascript" type="text/javascript"> function detectPopupBlocker() { var czmTest = window.open("http://www.radiotrips.com/czmradio/player/mini/no_ads.html","Cozumel Radio","width=478,height=260"); if (!czmTest) { alert("We were unable to automatically open the Cozumel Radio Player due to your pop-up blocker... Please add CozumelRadio.net to your allowed sites for your best listening experience"); } else { window.open("http://www.radiotrips.com/czmradio/player/mini/no_ads.html","Cozumel Radio","width=478,height=260"); } } ************** if anyone could add the code that would make the browser check to see if this window is already open and if so not reload it I would GREATLY appreciate it. I feel like it is 1 to 2 lines of code max according to what I have seen elsewhere but just cant figure it out. Thanks a Million in advance Chris I am trying to dynamically add rows to a table when the user clicks a button. here my function Code: function addFocusArea()
{
if(addTlFocusAreaCount <= 5)
{
//Create new Title row
var titleRow = document.createElement("tr");
var titleCol = document.createElement("th");
var titleText = document.createTextNode("Additional Focus Area " + addTlFocusAreaCount);
titleCol.appendChild(titleText);
titleRow.appendChild(titleCol);
document.getElementById("focusTable").appendChild(titleRow);
//Create new category row
var categoryRow = document.createElement("tr");
var categoryCol = document.createElement("td");
var categorySelect = document.createElement("select");
var categories = document.getElementById("<%=DecisionToolKeys.PRIMARY_FOCUS%>");
//copy a dropdown menu that is already existing on the page
for(var i=0; i<categories.length; i++)
{
var option = document.createElement("option");
option.value = categories[i].value;
option.text = categories[i].text;
categorySelect.options.add(option);
}
categoryCol.appendChild(categorySelect);
categoryRow.appendChild(categoryCol);
document.getElementById("focusTable").appendChild(categoryRow);
addTlFocusAreaCount++;
}
else
{
alert("You cannot add more than five additional practice areas.");
}
}
And here is my button Code: <input type="button" value="Add Focus Area" onclick="JavaScript:addFocusArea()"/> This is working in Firefox and Chrome, but not IE 8. Any clue as to why? Thanks, Nick Hi all, ok firstly i know all but nothing about javascript and you prob about to see the worst attempt eva at trying to understand it ok so here is my js code Code: <script language="javascript">
function selectElement(idElement)
{
var ratingval = "";
liElement = document.getElementById('sel'+idElement);
lirating = document.ratingform.userrating.value;
if(liElement == "sel1")
{
raingval = "1";
lirating = "1";
}
if(liElement == "sel2")
{
raingval = "2";
lirating = "2";
}
if(liElement == "sel3")
{
raingval = "3";
lirating = "3";
}
if(liElement == "sel4")
{
raingval = "4";
lirating = "4";
}
if(liElement == "sel5")
{
raingval = "5";
lirating = "5";
}
}
</script>
and here is my html code Code: <form name="ratingform" action="" method="post">
<fieldset class="login">
<legend>Personal Details</legend>
<div>
<label for="fname">First Name</label> <input type="text" id="fname" name="fname" value="<?php if(isset($_POST['fname'])){ echo $_POST['fname'];}?>">

</div>
</fieldset>
<fieldset class="rating2">
<legend>Rating</legend>
<div>
<label for="rating">User Rating</label>
<ul class="rating">
<li id="current" class="current" style="width: <?php echo $_GET['rating']?>em;"></li>
<li id="sel1"><a onclick='onClick="javascript:selectElement(1)' class="rate1" title="I hated it">*</a></li>
<li id="sel2"><a href="?rating=2" class="rate2" title="I disliked it">*</a></li>
<li id="sel3"><a href="?rating=3" class="rate3" title="It was OK">*</a></li>
<li id="sel4"><a href="?rating=4" class="rate4" title="I liked it">*</a></li>

</ul>
</div>
</fieldset>
<div>
<input type="hidden" name="userrating" value="" />
<input type="submit" name="Submit" value="Submit"><?php if($error == TRUE){echo $message;}if($submit == TRUE && $error == FALSE){echo $message;}?></div>
</form>
ok so what im trying to acheive is that when a user clicks on either of the rating links, a js function is run which gets the li value and then sets a value of a varible to match the li value and then i want to add that value to the hidden userrating form input and set the value of <li id"current" width value to the same value but as im sure youve noticed from my code it isnt working. any help it greatly needed and appreciated, thanks Luke I have a page that open two frames. Second frame, most of the page, is empty. First frame contains a form that retrieves user input, when you click the button, it send that input back to the original parent html, which detects the GET parameters, and builds a custom URL. I want to then load that custom URL in the 2nd empty frame. I figure I need to modify the src atttribute of the 2nd frame in the frameset, but I can't make it work. Code: <frameset id='parent' rows='10%,90%'>
<frame id='frm1' src='./form.html' />
<frame id='frm2' src='' />
</frameset>
<script>modFrmSrc();</script>
where modFrmSrc() checks for the GET values, builds the URL, and then tries to load the URL in frm2. Is there a way to get this done? Hi all, I sincerely apologise for the noob question. I have search and searched for an answer but to no avail, so I hope someone on here can help. I'm trying to get a fisheye verticle menu working. I've found somethin which fits the requirement he http://zendold.lojcomm.com.br/ifisheye/ and tried to make it work. It just doesn't. I've tried different versions of mootools etc but I think I'm missing something really stupidky simple. I'd really appreciate it if someone could have a look at my temp page (http://www.parkerbs.com/home1.htm) and point me in the right direction. Many thanks in advance. Paul Hi all, I'm desperately trying to figure out how to "transform" Javascript commands into HTML code. Excuse my noobness but I really know nothing about Javascript. Basically, I have this Google API Search code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>My Google AJAX Search API Application</title>
<script src="http://www.google.com/jsapi?key=CUT"></script>
<script language="Javascript" type="text/javascript">
//<![CDATA[
google.load("search", "1");
function OnLoad() {
// Create a search control
var searchControl = new google.search.SearchControl();
// Add in a full set of searchers
var localSearch = new google.search.LocalSearch();
searchControl.addSearcher(localSearch);
searchControl.addSearcher(new google.search.WebSearch());
searchControl.addSearcher(new google.search.VideoSearch());
searchControl.addSearcher(new google.search.BlogSearch());
// Set the Local Search center point
localSearch.setCenterPoint("New York, NY");
// Tell the searcher to draw itself and tell it where to attach
searchControl.draw(document.getElementById("searchcontrol"));
// Execute an inital search
searchControl.execute("Google");
}
google.setOnLoadCallback(OnLoad);
//]]>
</script>
</head>
<body>
<div id="searchcontrol">Loading...</div>
</body>
</html>
Now, what I'm desperately trying to do since 4-5 hours is to have the search results between the <div id="searchcontrol"></div> encoded as HTML in the loaded page. Currently, when the page is loaded and I look at the source code, I have the word 'Loading...' in the <div> tags, despite in the normal view there are G results listed. I need those results encoded as HTML for SEO reasons. Researching on this matter I thought the problem could be the OnLoad command, that makes the script load after all the other HTML elements are loaded. But I tried to make it load before all the elements in the page, and the problem persists. How can I solve this? Thanks in advance for any help! Hello everybody! This is my first post at CodingForums! I'm currently designing a wordpress theme, and I require a bit of javascript for a hover effect. I'm using Wordpress Jquery + Jquery Color Animations plugin. The structu I use a div (class="post") as a container for the wordpress post, and within the "post" div, I have a span (class="title") which I use to display the title of the post. What I want to do is: when the user hovers over (OnMouseOver) "post" div: ".title" spans's background color fades from black to red. when the user hovers out (OnMouserOut) "post" div: ".title" spans's background color fades back to black. The Code Code: $j(document).ready(function(){
$j(".posts").hover(function(){
$j (".posts .title").animate({ backgroundColor: "#FF0062" }, 300);
},function(){
$j(".posts .title").animate({ backgroundColor: "#231F20" }, 300);
});
});
The Problem The code works, except when the user hovers over any "post" div, all "title" span change color. So my question is, how do I target the code to address ONLY the "title" span in the "post" div that is in hover state? Any help would be greatly appreciated, Cheers, Drew. There has to be a way to do what I want to do but I'm fugged iif I know how. Here's the problem... A page has three frames - top, left and disp. Top and left contain a number of buttons that display another page in disp. All the buttons need to behave as one set of radio buttons; when a button is clicked any other button returns to the non-clicked state. The really awkward bit is there's an image in top that changes depending on the currently clicked button and that image is behind the buttons. Here it is in pseudocode of sorts. Code: On click button[n]
Button[LastClicked].Image := Button[LastClicked].UnClickedImage;
Button[n].Image := Button[n].ClickedImage;
Top.Image := Button[n].TopImage;
end;
I hope that makes sense. If some kind soul has any idea of how to do that I'd be very grateful. Thanks. Simon. how can i make a button that takes the user to the top of the page without the url#top being displayed in addy bar? i just dont like the way it looks thanks peeps Hello. I am a new user. I have got a website, www.eastbourneinks.co.uk where the quantity buttons (+) & (-) do not work on most computers where I have had feedback. Is there any way of making them work on any/all computers. This is one of the pages: http://eastbourneinks.co.uk/product/...nk-cartridges/ Many thanks. Phil. I have the following buttons ... Code: <input id="newTaskButton" type="button" name="Good Morning" value="201" /> <input id="newTaskButton" type="button" name="Hello World" value="201" /> ... and the following javascript ... Code: <script type="text/javascript">
$(document).ready(function() {
$("#newTaskButton").click(function() {
alert(" " + document.getElementById("newTaskButton").name);
});
});
</script>
... but I am having some trouble having the second button to response. My objective is to have 2 or more button that have the same click function (in this case, newTaskButton) but when clicked, it will produce different response. (in this case, the first button will response 'Good Morning' while the second button will response 'Hello World') Appreciate any help. Alternatives are welcome too. To be clear my approach to coding is basically that of building some kind of Java Frakenstein's Monster... which also explains why everything I create invariably ends up in a windmill on fire... This is what I have managed to put together so far: Code: <script type="text/javascript">
var homeDown = new Array()
homeDown[0] = "images/home001.png";
homeDown[1] = "images/home002.png";
homeDown[2] = "images/home003.png";
homeDown[3] = "images/home004.png";
homeDown[4] = "images/home005.png";
homeDown[5] = "images/home006.png";
homeDown[6] = "images/home007.png";
homeDown[7] = "images/home008.png";
homeDown[8] = "images/home009.png";
homeDown[9] = "images/home010.png";
homeDown[10] = "images/home011.png";
homeDown[11] = "images/home012.png";
homeDown[12] = "images/home013.png";
homeDown[13] = "images/home014.png";
homeDown[14] = "images/home015.png";
var homeOver = new Array()
homeOver[0] = "images/image001.png";
homeOver[1] = "images/image002.png";
homeOver[2] = "images/image003.png";
homeOver[3] = "images/image004.png";
var x=0;
function NormalImage()
{
document.getElementById("button1").src="images/home.png";
}
function MouseOver()
{
document.getElementById("button1").src=homeOver[x];
x++;
setTimeout("MouseOver()", 8);
}
function MouseDown()
{
document.getElementById("button1").src=homeDown[x];
x++;
setTimeout("MouseDown()", 8);
}
</script>
...and the HTML: Code: <a href="http://www.google.com"> <img id="button1" src="images/home.png" onmousedown="MouseDown(button1)" onmouseover="MouseOver(button1)" onmouseout="NormalImage(button1)"/> </a> I'm sure that's probably the wrong way of doing it but it vaguely works. What I ultimately want is a button that will play the long image sequence on click and the shorter sequence on mouse over. However at the moment it appears that the states of the mouse being over and clicked are clashing so I need something to ignore mouseover images on click and another bit to reset the count on mouseover so it can play again. If I remove the mouseover event the animation on mousedown plays well, though I suspect it might be necessary to preload the images when it's online. Alternatively if anyone feels like writing a much easier bit of script that will do the same thing and slap me for being stupid that is acceptable too... I'm currently working at school on a website and I cycled through aloooot of tutorials, but I couldn't find anything >.< so the qeustion is how to make a VERY simple javascript div tag replacer using buttons. so if I click for example button 1 then I want div tag 1 replaced with div tag 2 and when you press button 2 div tag 1 or 2 gets replaced with div tag 3. the closest tutorial I found was: Replace one div with another I can't get the radio buttons to work properly in my browser. If you don't press one the alert box does not tell you that you have to tick either male or female. Also I noticed you can tick both but it won't say you must choose only one, how can I sort this...any help please. case "radio_hidden": if (fld.value != "1")/* radio male or female button should be checked*/ { fld.valid = true; } break; if (frm.radio_hidden.valid == false) { report_text += " You must click a radio button male or female.\n\n" } <br><u>Select Your gender:</u><br> <input type="radio" name="male" value="" onchange="radio_hidden.value = 1;"> Male <br> <input type="radio" name="female" value="" onchange="radio_hidden.value = 1;"> Female <br> <input name="radio_hidden" value="" type="hidden"> Hi, I'm a year 11 student studying GCSE computing. I'm doing a project and I need to conduct some primary resarch, so I would be grateful if someone could explain to me how to go about coding radio buttons in a HTML web page which uses JavaScript. Thank you! |
