JavaScript - Need Some Major Javascript Help
My professor asked us to make a webpage that has a user register and login in via a xml document. We can omly use html, javascrip and css. I made a function that loads users from an xml file and authenticates them. It works only on firefox and not IE. This is a problem because i am using ActiveXobject to write to the file. Any help will greatly be appreciated.
Here is my function that loads xml: Code: function ReadXML() {
try { xmlDoc = loadMyXML("xmlStudent.xml"); }
catch (objerr) { alert(objerr.description); }
xmlfile = xmlDoc.getElementsByTagName('student');
fname= xmlDoc.getElementsByTagName("firstname");
lname= xmlDoc.getElementsByTagName("lastname");
usernames = xmlDoc.getElementsByTagName("username");
passwords = xmlDoc.getElementsByTagName("password");
}
Here is the xmlfile Code: <?xml version="1.0" encoding="utf-8"?>
<!--My first xml file (^-^) -->
<CST2309>
<student>
<firstname>bob</firstname>
<lastname>harris</lastname>
<username>admin111</username>
<password>11111111</password>

One is a drop down menu at the top of the site, another is an AJAX add to cart thing that loads the product to the cart without refreshing the page. Here's the problem. If someone adds a product to the cart and goes to view the cart, the space where the cart information usually is will be empty. The sidebar, top navigation, footer, all that, is still there. The cart info itself is gone. What we have noticed is if you add say 2 different products to the cart, view the cart (empty page at this point), and then use the drop down cart summary in the header to remove a product from the cart summary, the cart info will all of a sudden appear as it should. Refresh the page and it goes away again. It seems like removing the product from the cart summary in the header forces the AJAX add to cart feature to re-load the cart bringing it back. It just isn't loading initially. We have no idea why it quit working. It has been working for nearly two months with no problem. Here is a link to the site, you can test it yourself. soundisolationstore dot com The checkout works fine, just not the cart page.

I have a function which allows the number of buttons selected depending on the number selected from the drop down menu. Problem is that this code works in all of the major browsers except for Internet Explorer (No Suprise). For example if user chose the number 3 from the dropdown menu, then user can only select 3 buttons. Why is it not working in Internet explorer and what can be used to make it work in Internet Explorer? Below is javascript functions: Code: function getButtons()
{
document.getElementById("answerA").class="answerBtnsOff";
document.getElementById("answerA").setAttribute("class","answerBtnsOff");
document.getElementById("answerA").setAttribute("className","answerBtnsOff");
document.getElementById("answerB").class="answerBtnsOff";
document.getElementById("answerB").setAttribute("class","answerBtnsOff");
document.getElementById("answerB").setAttribute("className","answerBtnsOff");
document.getElementById("answerC").class="answerBtnsOff";
document.getElementById("answerC").setAttribute("class","answerBtnsOff");
document.getElementById("answerC").setAttribute("className","answerBtnsOff");
document.getElementById("answerD").class="answerBtnsOff";
document.getElementById("answerD").setAttribute("class","answerBtnsOff");
document.getElementById("answerD").setAttribute("className","answerBtnsOff");
document.getElementById("answerE").class="answerBtnsOff";
document.getElementById("answerE").setAttribute("class","answerBtnsOff");
document.getElementById("answerE").setAttribute("className","answerBtnsOff");
currenttotal=0;
}
function btnclick(btn)
{
if(document.getElementById("numberDropId").value=="")
{
alert('You must first select the number of answers you require from the drop down menu');
return false;
}
if (btn.class=="answerBtnsOn")
{
btn.class="answerBtnsOff";
btn.setAttribute("class","answerBtnsOff");
btn.setAttribute("className","answerBtnsOff");
currenttotal--;
return false;
}
if(document.getElementById("numberDropId").value==currenttotal)
{
alert('You are not allowed beyond the limit of the number of answers you require, deselect other button');
return false;
}
if (btn.class=="answerBtnsOff")
{
btn.class="answerBtnsOn";
btn.setAttribute("class","answerBtnsOn");
btn.setAttribute("className","answerBtnsOn");
currenttotal++;
return false;
}
}

Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. 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 Hi Guys I am trying to modify the functionality of my page. I want to be able to activate this piece of code using another javascript function. This is the code I want to activate: Code: <script type="text/javascript"><!--
$('#button-cart').bind('click', function() {
$.ajax({
url: 'index.php?route=checkout/cart/update',
type: 'post',
data: $('.product-info input[type=\'text\'], .product-info input[type=\'hidden\'], .product-info input[type=\'radio\']:checked, .product-info input[type=\'checkbox\']:checked, .product-info select, .product-info textarea, .date_data input[type=\'text\']'),

if (json['error']) {
if (json['error']['warning']) {
$('#notification').html('<div class="warning" style="display: none;">' + json['error']['warning'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.warning').fadeIn('slow');
}
for (i in json['error']) {
$('#option-' + i).after('<span class="error">' + json['error'][i] + '</span>');
}
}
if (json['success']) {
$('#notification').html('<div class="success" style="display: none;">' + json['success'] + '<img src="catalog/view/theme/default/image/close.png" alt="" class="close" /></div>');
$('.success').fadeIn('slow');
$('#cart_total').html(json['total']);
$('html, body').animate({ scrollTop: 0 }, 'slow');
}
}
});
});
//--></script>
And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please 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 got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>

</select>
<input type="submit" />
</form>
<?php
echo ('<select>');
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php
$dirkomik = $_POST['kodekomik'];
$exploded = explode("|", $dirkomik);
echo ($exploded[0]); //picture directory
echo ("<br>");
echo ($exploded[1]); //total page in the comic
$pagecount = (int)$exploded[1];
//Take last posted value, process it right away
echo ('<FORM name="guideform"> ');
echo ('<select name="guidelinks">');
$i=1;
do {
echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
$i= $i+1;
}while($i <= $pagecount); //Printing option and select
echo ("</select>");
?>
<input type="button" name="go" value="Go!" onClick="document.getElementById('im').src=document.guideform.guidelinks.options[document.guideform.guidelinks.selectedIndex].value+'.png';"> </FORM>
<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can... I want to insert this js snippet Code: function addText(smiley) {
document.getElementById('message').value += " " + smiley + " ";
document.getElementById('message').focus();
return false;
}
to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>');
.... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none'
but how do I insert js in the head of loaded iframe? All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero I wrote a log function that took note of various function calls. Thinking that functions are first class objects, and objects have properties, I made the name of each logged function a property of that function, e.g., brightenInnerPara.name = "brightenInnerPara"; Every browser I tried (Firefox, MSIE, Opera, Chrome, Safari) accepted the assignment, no problem. In Firefox and MSIE, the result was what I wanted: brightenInnerPara.name == "brightenInnerPara" But in the others, the result was: brightenInnerPara.name == null Question 1. Which Javascript is correct here? I favor Firefox and MSIE, not merely because they were willing to give me what I wanted, but also because it makes no sense to accept an assignment statement without throwing an error and then give it a null semantics, like Chrome, Opera, and Safari did. I found a workaround, using assignments like this: brightenInnerPara.prototype.name = "brightenInnerPara"; To my surprise, that worked in every browser. But I don't know why. It seems that such assignments are enough to cause each function to have its own distinct prototype. Question 2. Just how inefficient is my workaround, and why does it work? Hello friends, I need a help in HTML and java script I want that whenever i scroll the HTML page downwards then when i reaches at the bottom of the page then some event should get fired or some action should get performed like twitter I don't understand, how can i do that ? I've got a call from an HTML form to a getBoardsSold() function Code: <input value="Show Me the Money" type="button"
onClick="getBoardsSold();" />
the function is Code: function getBoardsSold() {
createRequest();
var url = "getUpdatedBoardSales-ajax.php";
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
}
Why do I always receive the error Object required line 101 (refering to the function call). Seems it isn't recognizing the function mark Hi everyone, I'm trying to generate a drop down list using a supplied xml form with an xsl sheet. Because xsl lacks commands that will allow me to create repetitive <options> I am using javascript. A sample xml file that I am using is bellow. Code: <?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="a.xsl"?> <Country> <California> <County>San Diego</County> <County>Los Angeles</County> </California> <Nevada> <County>Reno</County> <County>Las Vegas</County> </Nevada> </Country> The xsl file that I'm using is show below. Code: <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<head></head>
<body>
<p>This loaded</p>
<form>
<select name='County'>
<script type="text/javascript">
var i=3;
while(i > 0){
document.write("<option><xsl:value-of select='Country/California/County[");
document.write(2);
document.write("]'/></option>");
i--;
}
</script>
</select>
</form>
<script type="text/javascript">
var i=3;
while(i > 0){
document.write("<xsl:value-of select='Country/California/County[");
document.write(2);
document.write("]' /> <br />");
document.write("<xsl:value-of select='Country/California/County[2]'/><br />");
i--;
}
</script>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
Bassically all I'm trying to do is list the counties under california. My problem is that the javascript will print the list no problem but it only prints san diego even if my xpath index = i, is set to two. When i is set to 2, it should display Los Angeles. The following sample code will display Los Angeles Code: document.write("<xsl:value-of select='Country/California/County[2]' />");
However when the document has i = 1, it should display san diego. Unfortunately when i use i = 2 and write ... Code: document.write("<xsl:value-of select='Country/California/County["
document.write(i);
document.write("]' />");
or even Code: document.write("<xsl:value-of select='Country/California/County[");
document.write(2);
document.write("]' />");
The xsl sheet will display san diego instead. If the code is used without brackets you can see that everything is being displayed correctly ... for instance writting Code: document.write("xsl:value-of select='Country/California/County["
document.write(i);
document.write("]' /");
will result in .. Code: xsl:value-of select='Country/California/County[2]' / Why is xsl doing this to me? Hi all I am having x.php file in that i have included (y.js file). x.php code <? $username = "Kelvin"; ?> y.js code (external file) var username =<?php echo'$username';?> alert(username) It is not working for me. How can i get the php variable in external js file. Any help! |
