JavaScript - Help With My Robust Script Code
Quote:
<html> <body> <script type="text/javascript"> N = prompt ("Enter your Name", "") Q1 = prompt ("Enter your First grade", "") Q2 = prompt ("Enter your Second grade", "") Q3 = prompt ("Enter your Third grade", "") CS.toFixed() = parseInt(Q1) + parseInt(Q2) + parseInt(Q2)/3 M.toFixed() = prompt ("Enter your Major Exam", "") M.toFixed() = ((CS.toFixed()*.6) + (M.toFixed()*.4)) document.write ("Your grade is " + CS.toFixed() + M.toFixed()) </script> </body> </html> My problem is i want the output to not show points (2.7, 3.3) The code works when i dont put .toFixed() on my code also it shows it on document.write but when i put .toFixed() on my code it doesnt show up on document.write already tinkering it for half an our now but i give up Similar TutorialsSo, I have a situation in which I have a parent div.. <div id="parent"> </div> On page load that is empty but I have to make an ajax call to grab some XML and populate some structured elements. These elements, could be a few, need to then be appended into the "parent" div. Basically, read in the data, format it then innerHTML or bottom it to parent div. The thing is.. I have access to the prototype library and I can only think of the easy way of.. grab the nodes in the xml and use "new element" to create the display and slot in the xml data. THEN append it to parent and just loop thru the xml nodes and repopulate, append etc.. till done. But I am thinking this is old school. Is there a better, more robust, classier way of doing this. Is there a way to actually "pre=code" the display (and just style hide it) and "read in via jascript" the display and slot in the xml values and append it, then "show" it. like clone it, display it - etc... Something is telling me I can create a display object and slot the xml into it, append it and then keep calling to this display object. but not sure how to begin.... I am wondering if there is a way to display feeds from multiple sources on my page using this tool. The feeds are at the following URL http://www.vanityasart.com/viastorm.com/news.html It loads the first feed fine and then stops loading the others. Any ideas? H I'm trying to get my Client Side Firefox DHTML app to display a list of eBooks. For this, i have the following files F:\Textbooks.html F:\eBooks.txt F:\FirstBook.txt F:\SecondBook.txt F:\ThirdBook.txt textbooks.html is my DHTML app eBooks.txt is the Library file with a listing of all of my eBooks. Inside of eBooks.txt is the following data: ----------------- FirstBook.txt, SecondBook.txt, ThirdBook.txt, ----------------- FirstBook.txt to ThirdBook.txt are my actual ebooks. The problem that i'm having is that When i try to click on any buttons other than the FirstBook button, i get the following error: ---------------------------------- Error: unterminated string literal Source File: file:///F:/Textbooks.html Line: 1, Column: 10 Source Code: LoadEbook(' ---------------------------------- So, unlike clicking on the FirstBook button, these other buttons do not load the eBook data into the DIV for displaying the eBook data. I use the DOM insepector to checkout the DOM of the button code, and it seems like whitespace maybe is the problem. However, i have removed whitespace from the HTMLdata string, and that's not fixing the problem. did i forget something silly? LOL i'm using FireFox 3.5 to develop this App. So obviously this will not work with anything other than Gecko Based browsers. here is my HTML code: <html> <head> <script language="JavaScript"> var eBookLibrary = "eBooks.txt"; var SystemPath = "f:" + String.fromCharCode(92) function Init() { // Initialize the eBook reader document.getElementById("EbookCanvas").style.visibility = "hidden"; document.getElementById("EbookToolbar").style.visibility = "visible"; document.getElementById("FileManager").style.visibility = "visible"; // Load the List of eBooks in the Library LoadBookList(); } function UpdateEbookList() { // Update the Library of Ebooks alert("Updating eBook Library"); // Go back to the File Manager, and Reload the List of Ebooks LoadBookList(); } function LoadBookList() { // This will load the list of books that are available var EbookList = LoadFromDisk(SystemPath + eBookLibrary); var EbookListArray = EbookList.split(","); for(var x = 0; x < EbookListArray.length -1; x++) { // Strip the Filename Extension off of the eBook File Name // The Name of the Book is always the first Index in the Array var BookName = EbookListArray[x].split("."); // Remove the weird whitespace - it screws things up...i think... BookName[0] = BookName[0].replace(/(^\s*|\s*$)/g, ""); var HTMLdata = HTMLdata + "<input type='button' value='" + "FirstBook" + "'" + " onClick=LoadEbook('" + EbookListArray[x] + "');><br>"; } // For some ****ed up reason the first string always generates an 'undefined' even though it's nonsense // So just delete that from the HTMLdata string, because it's just ugly - LOL HTMLdata = HTMLdata.replace("undefined", ""); HTMLdata = HTMLdata.replace("", " "); // Write the HTML data to the DIV document.getElementById("FileManager").innerHTML = HTMLdata; } function LoadEbook(EbookName) { // Hide the File Manager and Show the Ebook Canvas document.getElementById("FileManager").style.visibility = "hidden"; document.getElementById("EbookCanvas").style.visibility = "visible"; document.getElementById("EbookToolbar").style.visibility = "visible"; // Load the Ebook content into the Ebook Reader Pannel var EbookContent = LoadFromDisk(SystemPath + EbookName); document.getElementById("EbookCanvas").innerHTML = EbookContent; } function LoadFromDisk(filePath) { if(window.Components) try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); var file = Components.classes["@mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile); file.initWithPath(filePath); if (!file.exists()) return(null); var inputStream = Components.classes["@mozilla.org/network/file-input-stream;1"].createInstance(Components.interfaces.nsIFileInputStream); inputStream.init(file, 0x01, 00004, null); var sInputStream = Components.classes["@mozilla.org/scriptableinputstream;1"].createInstance(Components.interfaces.nsIScriptableInputStream); sInputStream.init(inputStream); return(sInputStream.read(sInputStream.available())); } catch(e) { //alert("Exception while attempting to load\n\n" + e); return(false); } return(null); } </script> </head> <body onLoad="Init();"> <div id="FileManager" style="position: absolute; top: 0px; left: 0px; visibility: visible;"> The eBook Library's List of Books will be listed here.

Im not good with JS at all hello, i am looking a a specific javascript code for a school project. what the code does is it re-sizes your window to a specific size, and then makes it jump around to the four corners of your screen. a perfect example of this would be the rick roll site called http://www.20b.org/rickroll.html its best viewed in internet explorer, and will take effect after you allow it on the top pop up window. it seems that the latest version of firefox disables the window resizing and movement, so use IE. after examining the page source, i managed to find this code. window.resizeTo(640,625); window.moveTo(0,0); for (i = 1; i <= 9; i++){ setTimeout('window.moveTo(1599,1199);', i+"000"); i++; setTimeout('window.moveTo(0,1199);', i+"000"); i++; setTimeout('window.moveTo(1599,0);', i+"000"); i++; setTimeout('window.moveTo(0,0);', i+"000"); } the code worked perfectly on the macs used at school. but however, when i took it home and tried it on my PC, which has a different sized monitor, it didnt work right. my copied code section seemed to jump off the edges of the screen, like it was using the size of a Macs monitor, yet the original website works fine. this led me to believe that the source code seems to find the size of the monitor and adjust the position of where it moves. i cant seem to find that part of the code. any help would be appreciated I need a java script code that can be installed in to my chrome (plugin) but all it will do is. Code: If (code) is display quite current tab. else if code isnt displayed leave tab open. The code would the zip code that is filled in on a page like this. http://www.locationary.com/place/en/...1023990998.jsp to see the code properly you need to sign in to the site (free sign up takes like 2 seconds) so if zip code is filled in then quit tab please any help on this would be great Hi First sorry for my bad English! may any one interpret the JavaScript code below for me?

However, when a person has a bunch of items in their cart, and they want to minimize it for the rest of their browsing experience, every time a new page loads, or a refresh happens, the floating cart un-minimizes and expands out fully again displaying all the items. This can become very annoying during the shopping experience when you have a bunch of items loading and just taking up space in the browser. Therefore, I am wondering if their is some html or script that would save the minimizing in the floating cart, and carry it over to the next page, and the rest of the browsing on site? Thank you for any suggestions/help. I am new to HTML and script writing, but I am eager to learn. Hopefully in the future, I won't be paying for little changes like this every time I need one. Hello, I have an html script and a .php script. The .php requests a random word from a table of words in a mysql database. I wrote a html form to display the requested word in a text box. Here is my html file: Code:
<html>
<body>
<script type="text/javascript">
function myfunction()
{
var xmlhttp;
if(window.XMLHttpRequest)
{
xmlhttp= newHttpRequest();
}
else
{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if(xmlhttp.readyState==4)
{
document.myLingo.word.value=xmlhttp.responseText;
}
}
xmlhttp.open("GET", "get_Word.php",true);
xmlhttp.send(null);
}
</script>
<form name="myLingo">
<input type="button" name="button" value="New Word" onClick="myFunction();" />
<input type="text" name="word" />
</form>
</body>
</html>
and here is my .php script: Code:
<?php
$con=mysql_connect('localhost', 'xxxx', 'xxxx');
if (!$con)
{
die('Could not connect: '.mysql_error());
}
mysql_select_db("my_lingo", $con);
$sql=mysql_query("SELECT `word` FROM `words` ORDER BY RAND()") or trigger_error('Error: ' .mysql_error());
$word=mysql_fetch_array($sql);
echo $word[0];
mysql_close($con);
?>
When I run this in Internet Explorer; I get a error that is asking for an object on line 32 which is the line that has my button in the javascript. When i run it in firefox, I don't receive an error, but the page still does nothing. Any suggestions? The main function of the page is that, when I click the button, it's supposed to return me a random word from the .php script Thanks, jcjst21 Hello all,I have a website and I would like a pop-up window to promote a new website venture I have. I would like for the new website to open in a completely new window/browser when my members simply click on the index page (No link or Buttons).The code below does most of what I ask lol,but it.. 1.Only opens in a new tab (in same browser) while I would like for it to open in a completely new browser "full page" menu bar scroll tab and all. plus 2.It seems to open each and every time the page is clicked,which will be annoying to my members.I would only like for it to open 1 time per visitor every 24 hours or whenever cookies are cleared. Code: <html>
<head>
<script type="text/javascript">
function click_on()
{
window.open("URL HERE", "_blank");
}
</script>
</head>
<body onclick="click_on()">
</body>
</html>
I am no expert at this,and my knowledge is very limited,so excuse me if this is a simple situation.Any help would be greatly appreciated. Thanks, Roco Hi, Please i am not getting clear understanding of a javascript code to redirect user to a different web page based on the day of the week. Please i have search for many script and not getting clear understanding from their code.I have also try several code myself but nothing good has come from it. Please can someone help me and write a descriptive code for me to understand better.I really plead you and your to help me...but i belief the Lord God will bless you for your time helping me. looking forward to here from you. Thank you. Clement Osei Hi All, I have two scripts which I want to try and integrate. I am using a nice gallery script to show thumbnails which are appended to a an image wrapper which on click of the thumbnail shows the larger image in the image wrapper, I am trying to implement cloud zoom which is a plugin which uses image srcs to then point to an anchor href to show another larger zoom image either in the same place.. which is what I am trying to do or in another div beside. I have had to set me img srcs up in a certain way to easily enter some product details. and I need to try an manipulate the code to make it work to suit my file layout. I am using a var= images [ with a series of file locations and info such as below { src: 'romanticabride/thumbs/tn_Shauna.jpg', srcBig: 'romanticabride/images/Shauna.jpg', title: 'Shauna', longDescription: '<b><H1>Shauna</H1></b><br><b>Romantica Of Devon <br><br><h2>Sizes Available:</h2><br> 6 - 32.<b><br><b><br><b><b><b><H2>Colours Available:</h2><b><br>Various<br>Please Enquire Below<br><br><br><br><a href="mailto:tracy@cherishbridal.co.uk?subject=Web Enquiry Regarding Romantica Shauna Bridal Gown"class="enquiry rose glow" >Click To Enquire About This Item </a>' }, what I need is for cloud zoom to work when the main image wrapper is hovered over which means it will need to add a class or when the whichever srcBig: is hovered over it gets wrapped by href to make the script work . one of my pages is http://www.cherishbridal.co.uk/romaticabride.html the cloud zoom script is at http://www.professorcloud.com/mainsite/cloud-zoom.htm.. I am happy to share a jsfiddle with someone or explain further or post some code. Thank you in advance does any expert know how to pass parameters in the <script ..> tag? for instance; Code: <script type="text/javascript" src="script.js ?param1=val1¶m2=val2&etc "> in the javascript script.js, how would we read the params after the question mark? for example, google this; google shopping cart /v2_2/cart.js I have a script that works in seamonkey(my html editor) but when I use it in IE8 it says errors happen. Here's the code (the first line is on line 7 of the html file): Code: <script type="text/javascript">
function enlarge(imageNum)
{
var numToString = "";
if(parseInt(imageNum) < 10){
numToString = "0" + imageNum;
}
else
{
numToString = imageNum + "";
}
window.open("images/LgScreenshot"+numToString+".jpg","Screenshot "+imageNum,"status=0,height=675,width=900,resizable=0");
}
</script>

Line: 18 Char: 1 Code: 0 URI: http://samssc2site.co.cc/Features.html This post will contain a few guidelines for what you can do to get better help from us. Let's start with the obvious ones: - Use regular language. A spelling mistake or two isn't anything I'd complain about, but 1337-speak, all-lower-case-with-no-punctuation or huge amounts of run-in text in a single paragraph doesn't make it easier for us to help you. - Be verbose. We can't look in our crystal bowl and see the problem you have, so describe it in as much detail as possible. - Cut-and-paste the problem code. Don't retype it into the post, do a cut-and-paste of the actual production code. It's hard to debug code if we can't see it, and this way you make sure any spelling errors or such are caught and no new ones are introduced. - Post code within code tags, like this [code]your code here[/code]. This will display like so: Code: alert("This is some JavaScript code!")
- Please, post the relevant code. If the code is large and complex, give us a link so we can see it in action, and just post snippets of it on the boards. - If the code is on an intranet or otherwise is not openly accessible, put it somewhere where we can access it. - Tell us any error messages from the JavaScript console in Firefox or Opera. (If you haven't tested it in those browsers, please do!) - If the code has both HTML/XML and JavaScript components, please show us both and not just part of it. - If the code has frames, iframes, objects, embeds, popups, XMLHttpRequest or similar components, tell us if you are trying it locally or from a server, and if the code is on the same or different servers. - We don't want to see the server side code in the form of PHP, PERL, ASP, JSP, ColdFusion or any other server side format. Show us the same code you send the browser. That is, show us the generated code, after the server has done it's thing. Generally, this is the code you see on a view-source in the browser, and specifically NOT the .php or .asp (or whatever) source code. I need to assign a key in the javascript to actually make the javascript work,. I have a bookmark in chrome , a javascript , which actually works when clicked on it .,. but how can i edit it so that i can actually make it work on click a key or combination of keys. i want to declare the key or keycombo in the script itself .,. the script is for catching the selected text on the webpage and opening a new tab(or window) and doing an exact search search of the selected text using google.com .,., So I want it to work it this way ., select the text press a key and it opens a new tab (or window) with an xact search .,. i want to declare the key or keycombo in the script itself .,. the script is for catching the selected text on the webpage and opening a new tab(or window) and doing an exact search search of the selected text using google.com .,., So I want it to work it this way ., select the text press a key and it opens a new tab (or window) with an xact search .,. Thanks in advance ., Nani On this website: http://evancoleman.net/index.php I really like on the top how the menu has like 5 or 6 icons, and when you hover over them it shows a bubble with the name in them. Does anybody know where I can find this script? Thanks. Hi all, I hope someone can advise whether such a script exists for what am wanting to do. From time to time, I need to send password information or login details and password information to some users. At the moment, am doing it via email with a subject named FYI and the body of the email basically just contain the login and the password or in some case, just the password. What am wanting to know is whether I can put these information into a HTML file which contains an obfuscated Javascript with a button that a user will click that will prompt for his login information and then will display the password. In its simplest form, I guess I am looking for a Javascript that will obfuscate a HTML file that contains the password. Anyway, hopefully someone understand what am looking for. I found some website that offers such service as obfuscating a HTML file but am hoping it can be done via a Javascript so it is at least "portable" and I do not have to be online. Any advice will be much appreciated. Thanks in advance. Hey everyone here is my code for looking up a city, and state by zip code.

If the textbox is null then a global variable is false otherwise a checkbox is checked and the global variable is true. below is what i have done so far, please assist me. var isValid = false; window.onload = startForm; function startForm() { document.forms[0].firstName.focus(); document.forms[0].onsubmit = checkEntries; alert("You have been added to the list") } function checkEntries() { var menus = new Array(); var formObject = document.getElementsByTagName('*'); for (var i=0; i < formObject.length; i++){ if (formObject[i] == "myform") menus.push(formObject[i]); if (document.forms[0].firstName.value.length==0 || document.forms[0].firstName.value.length == null){ isValid= false; alert("Please enter a first name"); } else (document.forms[0].check0.checked=true); isValid=true; if (document.forms[0].lastName=="" || document.forms[0].lastName== null){ alert("Please enter a last name"); isValid = false; } else (document.forms[0].check1.checked=true); isValid=true; if (document.forms[0].email=="" || document.forms[0].email== null) { alert("Please enter a valid email"); } else return (document.forms[0].check0.checked=true); isValid=true; if (document.forms[0].bDate=="" || document.forms[0].bDate== null) { isValid=false; alert("please make sure you enter a valid birth date."); } else (document.forms[0].check0.checked=true); isValid=true; } } here is the form html... <form name="myform" > <input type="checkbox" name="check0" class="check0" id="check0" > First: <input type="text" name="firstName" id="firstName"> <BR> <input type="checkbox" name="check1" class="check1" id="check1" > Last: <input type="text" name="lastName" id="lastName" ><BR> <input type="checkbox" name="check2" class="check2" id="check2" > E-Mail: <input type="text" name="email" id="email"> <BR> <input type="checkbox" name="check3" class="check3" id="check3" > Birthday (mm/dd/yyyy): <input type="text" name="bDate" id="bDate"> <BR> <input type="submit" value="Join our mailing List" /> </form> |
