JavaScript - Data | User Interaction | Visualization
Hello,
I am looking for some strong resources about the topics above. I am trying to create a map for my website that visualizes Americas opinions on who will win the 2012 election... Obama vs the Republicans. I have a data set that will be the base, but I would like to update the map as users take the accompanying poll and as the data set changes. Any ideas or information would be awesome! Thanks Similar TutorialsI started using Google API Visualizations to create a bar chart which was very easy because of the code examples google gives but then I realised instead of setting the values I want within the html I wanted a form which would let you input the values you want for the bar chart. I made it look like this: Using this 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">

<SCRIPT LANGUAGE="JavaScript">
function UpdateChart (form) {
var TeamA = form.TeamA.value;
var TeamB = form.TeamB.value;
var TeamC = form.TeamC.value;
var TeamD = form.TeamD.value;
}

However, instead of the values I've bolded I want the values from the form to be used. I've never really used Javascript before so I'm not sure what to do. Any help would be appreciated. Hi all, I had posted earlier on the NaN issue. I have worked some more on my test file. Basically I want the user to select an option depending on whether he/she has Paracetamol in syrup or drops form. Once this is selected, automatically a different div for syrup or for drops should be seen depending on what the user selected earlier. After this on pushing the calculate button, the output should be appropriate depending on the strength of the solution either for drops or syrup. I have put together what I think code that should work but it stubbornly refuses to do otherwise. I have attached the relevant file. If it doesn't work, obviously there is something wrong but what it is eludes me. Any help will be appreciated greatly, Thanks, Hey all, I want to be able to update the line chart of google visualizations. Here is my code in question: http://jsfiddle.net/YCqyG/5/ Click the button called "click" and suddenly chart disappears. thanks for response This article ( http://www.webreference.com/js/column24/userdata.html ) explains how to do userdata persistence, but (like most things in ie) the code is in the source. Anyone know if you can do user data persistence dynamically in ie? Could I create the requisite metatag and css rule on-demand, instead of in the source? Any tips/links welcome. Ok so I'm playing around with writing scripts reading through JavaScript: The Definitive Guide and I'm on the Section "Relationships Between Frames". All i'm trying to do is change the background color of the <div id=iframewrap> element, which is inside the iframe, by clicking on the paragraph that says "Click Me", which is inside the iframe's parent window. I have everything I tried below along with the error message recieved by firebug. I Cant figure it out. HTML Code: <p>Click below to change the style of the iframe</p> <p style="color:blue" onClick="chngFrameStyle()">Click Me</p> <iframe id="fone" name="fone" src="OreillyCh14v2Iframe.html" width="50%" height="400px" ></iframe> The iframe Code: <div id="iframewrap" > <h1>Iframe Window</h1> <div id="iframeparagraph"><p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

};
It will be best to use server side scripting like php for it , because user can disable his javascript in that condition your code won't work
Is it possible to use GetVariable() on a variable outside the Main scene timeline? Im trying to get a variable that is set on "sprite 479" that is gonna run on frame #2.. the variable name is "myVariable" Code: function getElement()
{
var FlashArr = document.getElementsByName('myFlash');
return FlashArr[FlashArr.length-1];
}
alert(getElement().GetVariable("myVariable"));
I can only get variables located on the MainMovie sprite. Thank you. I need to interact with application in a way that is being used by mouse and some keyboard clicking like save a text file to a desired location with a desired name by the java script file. Can you give me some information how to do that, and where to get information for that?
Hey all, Whenever firebug detects a js error on a page, it prevents you from interacting with the page, so you can't scroll, you can't click, you can't do anything except close the window. Anyway around this? Thanks. help me! im have 2 file .js file 1.js code: document.write("<script src=2.js></script>") document.write(f) file 2.js code: var f="hello" im want run 1.js get variable of file 2.js by 3.html but don't run! code 3.html <script src=1.js></script> Hello. Is it possible to use java script to direct users to different page depending on their username login and password? And if so, what is the script? The website i am creating is for a conference my school is hosting. What I want to do is give the username and password for each delegation to use; once they log in, they will be directed to a page which contains information pertaining only to their delegation. Right now, this is the script I have, but it only directs to one page, which is "user1.php". I want to be able to direct user2 to user2.php, user3 to user3.php and so on. <?php $usernames = array("user1", "user2", "user3", "superman"); $passwords = array("pass1", "pass2", "password3", "supermans password"); $page = "user1.php" for($i=0;$i<count($usernames);$i++){ $logindata[$usernames[$i]]=$passwords[$i]; } if($logindata[$_POST["username"]]==$_POST["password"]){ session_start(); $_SESSION["username"]=$_POST["username"]; header('Location: '.$page); exit; }else{ header('Location: login.php?wrong=1'); exit; } ?> Any help would be greatly appreciated. Thanks! So I have been working on this exercise for about a month. In the book I am reading it say's this:"For each number that the user enters, the text boxes on the web page should display: the last score that was entered, the number of scores that have been entered, the total of these scores, the average score, the best score, and the worst score. When you write the code for this function, you should enclose the prompt method within a loop, but you decide which type of loop is best for this application. Now, write and test the code." The first peice of code is my HTML, and the second piece of code is the function that I have to start from in a .js file. I just seem to be confused at how my structuring needs to be. The 999 in the function is what the prompt says to enter to escape. Code: <body>
<div id="content">
<h1>Using Loops</h1>
<label for="lastScore">Last Sco </label>
<input type="text" id="lastScore" /><br />
<p></p>
<label for="scoreCount">Score Count:</label>
<input type="text" id="scoreCount" /><br />
<label for="scoreTotal">Score Total:</label>
<input type="text" id="scoreTotal" /><br />
<p></p>
<label for="scoreAverage">Average Sco </label>
<input type="text" id="scoreAverage" /><br />
<label for="bestScore">Best Sco </label>
<input type="text" id="bestScore" /><br />
<label for="worstScore">Worst Sco </label>
<input type="text" id="worstScore" /><br />
<p></p>
</div>
Code: var process_test_scores = function () {
var testScore;
testScore = parseInt(prompt(
"Enter a valid test score between 0 and 100.\n" +
"To end test score entry, enter 999.", 999));
}
In a normal chatroom, when the user "says" something, the text will be displayed normally on a line with the date/time attached like the example below. 2011/11/09 Capypara: Blah balh blah I would like to make it so that the text typed in by the user will appear inside a graphic (square, or those chat bubbles) like the example below. The graphic will only appear when a user says something, so essentially both the graphic and the text will appear together. ~~~~~~~~~~~~~~~~~~~~~~~~ | | | 2011/11/09 Capypara: Blah balh blah | | | ~~~~~~~~~~~~~~~~~~~~~~~~ Is it possible to go about doing this? Thanks for reading this.

Hi all, I have been working on a map, which now works and highlights and shows the location name on mouseover. I am having problems with how to go about getting users to be able to click on a region of the map, and depending on which region is clicked, to populate a drop down list which will appear on the same page. Then, the option which is chosen from the drop down list, would populate a blank field for the user- eg. preferences 1 - 4. The next location, would populate another drop down list, and the chosen option would populate the next blank field, if the previous one is already filled. This is what I have for the drop down lists, where the drop down is only populated from "location" array and need to somehow incorporate other array lists "locationsSouth" , "LocationsEast" and others if they were chosen. Code: <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<html>
<head>
<title>Drop down box</title>
<script language="javascript">
function addOption(selectbox,text,value )
{
var optn = document.createElement("OPTION");
optn.text = text;
optn.value = value;
selectbox.options.add(optn);
}
function addOption_list(selectbox){
var location = new Array("location1","location2","location3");
var locationsSouth = new Array("location1.1","location2.1","location3.1")
var locationsEast = new Array ("location1.2","location2.2","location3.2")
for (var i=0; i < location.length;++i){ //
addOption(document.drop_list.Location_list, location[i], location[i]); //
}
}

Hello all, First off I would like to say a big hello and thank you to the forum for helping me with code over the years... I am trying to create an iframe with a user input, however, I dont simply want the iframe to display the URL the user has entered in the iframe. I want it to be used within a URL string. For example: The iframe should display http://www.google.co.uk/search?q=UserKeyword I havent got a clue where to start from.... Any help would be highly appreciated! Thanks! Hello all, I would like to implement a cookie feature on my site that when a user logs in a cookie is stored for him and the next time he comes back, he doesn't have to sign in. I have researched hotscripts and javascripts but the ones I have found have to do with the "remember me" and thats not quite what I want. I tried to manipulate it but with no luck. Any help with either posting code or an article would be greatly appreciated! Thanks a bunch-Dan In my onbeforeunload event, it asked the user whether they want to leave the page or stay on it. When they click "stay on page", I want it to then redirect them to another webpage in the same window. Is there a way to do this, without just showing/hiding divs? Can I override the function? I'm currently trying to do it this way(as seen below) but now the dialog box is not showing up at all. It was working before Any ideas as to what I'm doing wrong, or how to accomplish this task?
