All help is much appreciated!!! 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'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 Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated 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, 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 $_POST['fname'];}?>">
</div>
<div>
<label for="lname">Surname</label> <input type="text" id="lname" name="lname" value="<?php if(isset($_POST['fname'])){ echo $_POST['lname'];}?>">
</div>
</fieldset>
<fieldset class="contact">
<legend>Review</legend>
<div>
<label for="title">Review Title</label> <input type="text" id="title" name="title" value="<?php if(isset($_POST['title'])){ echo $_POST['title'];}?>">
</div>
<div>
<label for="review">Review</label> <textarea name="review" id="review" cols="33" rows="5"><?php if(isset($_POST['review'])){ echo $_POST['review'];}?></textarea>
</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 $_GET['rating']?>em;"></li>
<li id="sel1"><a onclick='onClick="javascript:selectElement(1)' class="rate1" title="I hated it">*</a></li>
<li id="sel2"><a href="?rating=2" class="rate2" title="I disliked it">*</a></li>
<li id="sel3"><a href="?rating=3" class="rate3" title="It was OK">*</a></li>
<li id="sel4"><a href="?rating=4" class="rate4" title="I liked it">*</a></li>
<li id="sel5"><a href="?rating=5" class="rate5" title="I loved it">*</a></li>
</ul>
</div>
</fieldset>
<div>
<input type="hidden" name="userrating" value="" />
<input type="submit" name="Submit" value="Submit"><?php if($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 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, 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">

google.load("search", "1");
function OnLoad() {
// Create a search control
var searchControl = new google.search.SearchControl();

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");

<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. please could you help me i am using highcharts and cant get the dates to show at the bottom from mysql over 5 days please could some one help me with this thank you here is the chart database layout code Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

thanks i got this code which will open a new link in a new window. Code: <script type="text/javascript">
$(function(){
$(".popup").click(function(event){
event.preventDefault();
var href = $(this.)attr("href");
var width = $(this.)attr("data-width");
var height = $(this.)attr("data-height");
var popup = window.open (href, "popup",
"height=" + height +",width=" + width + "");
});
});
</script>
This is the html which it should be targeting. Code: <li><a href="http://www.google.com" data-width="600" data-height="400" class="popup">Latest Posts</a></li> i'm just starting out with js/jq. i dont know what's wrong. thanks for your help. p.s I have explicitly tried the onclick approach where I already gave the function a name followed by () between quotes but same thing happens. The link opens in the same window. I tried posting this: <button type="button" onclick="JavaScript:alert('Let's assume.....')"> <img src="question.jpg" alt="Click here" /> <br />Click for Answer!</button> and it shows the button with the picture, but I am unable to click it. Can you please help me? Thank you in advance. 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. Ok so before you help, just letting you know i'm a BIG noob at coding so please give noob friendly instructions, that would be great thanks I also googled and it didn't help so don't ask. Ok so I'm sure a few people here have heard of the game minecraft? well someone i know (distant relation) showed me something that will track players in the game on servers and i just need help to get it working. He told me i need node js installed to get it working which i don't know how to do (I'm on a mac). I did install python because some people told me i need python to install node js but I'm not sure. So pretty much how do i get node js installed and after that, how do i get the player tracker thing working? heres the github url for the player tracker: https://github.com/koryk/griefguild Much appreciated to anyone that helps! I'm a nooblet so go easy and thank you! Hey! First off you guys rock! Second im a massive noob - like beyond noob. Ok so heres the deal guys and gals: I use Kampyle (a feedback form thing) and when my viewers click my feedback button a new window pops up and is the form. Like this (plus thats my site if you want to try it): However! theres this site (yes my arch enemy, well were actually two different things and hey i dont even speak their language) and they use the same feedback thing by Kampyle too. But the catch is theirs is inbuilt. something like Lightbox Javascript but for forms/windows. or Facebook's popup notices? so theirs looks like this: This make me ANGRY!!! cause i want that and ive had to ask stupid people cause you guys and gals are way too advance for me... well i am only 17... anywho... WHO CAN HELP ME??? if you want to test the difference between the two forms, my site: that creative corner and click the feedback button. their site:Lyoness and click the feedback button in the bottom right corner. THANK YOU SO MUCH!!! Hi, i am a newb trying to learn how to make websites and i'm having troubles with a chess board i'm trying to make. The point is that i want to be able to create lessons with it for children, as in make a specific setup and have one (or more, if possible) specific move(s) give a different result (like a popup-box or something) then a wrong move. I copied a drag and drop chessboard from the inet which i got figured out. But don't know how to create a "good move" and a "bad move". Here is some of the code: <head> <style type="text/css"> #chess_board { border:5px solid #333; } #chess_board td { background:#fff; height:50px; text-align:center; vertical-align:middle; width:50px; } #chess_board tr:nth-child(odd) td:nth-child(even), #chess_board tr:nth-child(even) td:nth-child(odd) { background:#ccc; } </style> <script type="text/javascript"> function allowDrop(ev) { ev.preventDefault(); } function drag(ev) { ev.dataTransfer.setData("Text",ev.target.id); } function drop(ev) { var data=ev.dataTransfer.getData("Text"); ev.target.appendChild(document.getElementById(data)); ev.preventDefault(); } </script> </head> <body> table id="chess_board" cellpadding="0" cellspacing="0"> <tr> <td ondrop="drop(event)"ondragover="allowDrop(event)" id="A8"><div class="piece" draggable="true" ondragstart="drag(event)" id="dragA8">♜</div ></td> this is only the first field this goes on with b8 c8 etc... </tr> <tr> a7 b7 etc... as u can see i am using html5 drag and drop for the piece-moving and a table to create the field, is it possible to create a if...else statement inside the drop functon to make only a specific piece able to accually be dropped (but maintain the ability to drag the other pieces) Thanks in advance, Jasper Rigters I'm having a problem. All i want to happen is this: The program asks you what's up. It gives you a prompt and the prompt message tells you to say "nm" (it means nothing much) And the if statement is that if you put nm into that prompt, it'll display a message. However, when i put in the prompt, even if i put in a bogus message, it'll still display the if statement. What do i do? Here's my code. Code: <html>
<head>
<title> The nothing much page! </title>
<script type="text/javascript">
var nmj;
alert("what's up man?");
var nmj = prompt("say nm , it means nothing much");
if (nmj = "nm")
{
alert("What!? Nothing much!? Sounds boring.")
}
alert(nmj);
</script>
</head>
<body>
NOTHING MUCH? WHATTT!?!?
</body>
</html>
