JavaScript - Error In Code - Need Help
We have an issue with some code in a js file. Could someone look at a portion of the code below that appears to start the problem, and let me know why this sends the program into an infinite loop. Any help would be appreciated....See below:
//The control parameter is typically not used; it is to allow us to call the function // without it being fired by an event. function Colorize(manualcontrol) { //If we don't have a control from an event bubble, try to get it as passed into the function if (!(event == null)) { if (!event.srcElement) control = manualcontrol; else control = event.srcElement; }[/COLOR] else { control = manualcontrol; [/B] } Similar TutorialsI'm getting a runtime error on the code in red. Can anyone see anything that is wrong with it? These functions are called by an onBlur by the way. <script type="text/javascript"> //THIS GENERATES QUANTITY OF MATERIALS function generate3() { var tot3 = document.ComplianceForm.materialamount.value; var tbl3 = document.getElementById("quantitymaterials"); if (tot3 > 28) { alert("16 is total amount of materials for now."); } else { for(var i =1; i<=tot3; i++) { tbl3.innerHTML = tbl3.innerHTML + '<tr><td colspan=\"2\"><hr /></td></tr><tr><td>'+i+') Quantity: <input type=\"text\" name=\"qty'+i+'\" size=\"3\"\/></td><td>Description: <input type=\"text\" name=\"material'+i+'\" /></td></tr><tr><td colspan=\'2\' \">Your Truck<input type=\"checkbox\" \/> Other truck<input type=\"checkbox\" \/> Cash<input type=\"checkbox\" \/> Credit Card<input type=\"checkbox\" \/> P.O.<input type=\"checkbox\" \/></td></tr>'; } tbl3.innerHTML = tbl3.innerHTML + '<br>'; } } function remove3() { var tot3 = document.ComplianceForm.materialamount.value; var tbl3 = document.getElementById("quantitymaterials"); for(var i =1;i<=tot3; i++) { tbl3.innerHTML = ""; document.ComplianceForm.materialamount.value = ""; tbl3.innerHTML = ""; } } </script> I'm pretty new to Javascript so don't lay into me too hard. haha thanks. -Ty Hi all, I am new to CodingForums.com as well as new to javascript. I am currently trying to create a small calculator for a friend which is to do with calculating a dose. The calculator itself works but I am now fine tweaking the text that appears with the calculated values. This is my code: Code: <script type="text/javascript">
function calculate() {
var IBW = 1;
var IBW2 = 1;
var dose2 = 1;
var CrCl = 1;
var hgtft = document.getElementById("height_feet").value - 0;
var hgtinches = document.getElementById("height_inches").value - 0;
var weight = document.getElementById("weight").value - 0;
var sex = document.getElementById("sex").value;
var age = document.getElementById("age").value - 0;
var creatinine = document.getElementById("creatinine").value - 0;
if (age < 16) {
alert("This tool is only for use in adult patients i.e. 16 years or older");
return; //process no further
}
if (sex == "M") {
if (hgtft < 5) {
IBW = 50;
IBW2 = 50;
}
else {
IBW = 50 + (2.3 * ((hgtft - 5) * 12 + hgtinches));
IBW2 = 50 + (2.3 * ((hgtft - 5) * 12 + hgtinches));
}
if (IBW > weight) {
IBW = weight
}
CrCl = ((140 - age) * IBW * 1.23) / creatinine;
}
else {
if (hgtft < 5) {
IBW = 45;
IBW2 = 45;
}
else {
IBW = 45 + (2.3 * ((hgtft - 5) * 12 + hgtinches));
IBW2 = 45 + (2.3 * ((hgtft - 5) * 12 + hgtinches));
}
if (IBW > weight) {
IBW = weight
}
CrCl = ((140 - age) * IBW * 1.04) / creatinine;
}
var dose = Math.round((5 * IBW) / 40.0) * 40.0
var IBW = Math.round(IBW, 1)
var IBW2 = Math.round(IBW2,1)
var CrCl = Math.round(CrCl, 0)
if (CrCl < 40) {
dose2 = "As GFR < 40mL/min Extended Interval Gentamicin is not indicated. Contact microbiology for an alternative agent";
}
else {
dose2 = dose "mg - Note: This dose has been calculated using a weight of " IBW "kg and rounded to the nearest 40mg to aid administration";
}
document.getElementById('IBW2').innerHTML = IBW2 + "kg";
document.getElementById('CrCl').innerHTML = CrCl + "mL/min";
document.getElementById('dose2').innerHTML = dose2;
}

What I am trying to do is have the dose displayed as: xxdose mg - Note: This dose has been calculated using a weight of IBWkg and rounded to the nearest 40mg to aid administration but if the CrCl is less than 40 then the dose message should be: As GFR < 40mL/min Extended Interval Gentamicin is not indicated. Contact microbiology for an alternative agent can anyone help me with this please? This is how this page should work: click on an abbreviation and see player info to the immediate right of the green field. The left-most 'WR' and 'RB' in the upper portion of the field (imagemap) have javascript assigned to them. Click on these to test. So far, I get no player info but I do get this error: 'eleObj.style' is null or not an object Here's part of the html ... is the script call in the right place????

My webpage is: www.fkcapitalfund.com So, I can't fix that error, I don't have the technial wherewithal to do it and the person who did the programming won't help anymore, he made the template for me and left me to my own devices unfortunately. Along the same lines as this, my goal is to get my page to load quicker and my appealing to google Any help to that end would be appreciated. Thanks Hi, I'm having problems tracking down the code that causes IE to throw an error where all other browsers work just fine. I have attached the menu.js file, two style sheets (one for IE, the other for all browsers, css code for menu is at the end), and a body.html file that calls the menu. Of course these are uploaded as text files, but please feel free to rename and run the body file! The IE error states that it's looking for an object after the script tag on line 18 of the body file that creates menu settings. What is wrong with this line, and how can I fix it? Many thanks for any help that can be provided! hello i have a form which when the user hits "submit," the info in the textboxes is entered to a database. the only textbox which is not entered to the DB is an "age" textbox, which i need to verify to see if user is 18yrs or older. if user is not 18 years or older, they get an alert telling them they arent 18+. if they are, then the form submits this is my code so far, and i dont get any alerts when i enter an age younger than 18: Code: <head>
<script language="text/javascript">
var age;
document.getElementById("userage").value = age;
if (age >=18)
document.location="feedbacksaveanddisplay.php";
else {
alert('Sorry, we can not let you in!')
document.location="content.html";
}
</script>
</head>
<form method = "post" action = "FeedbackSaveAndDisplay.php">
<input type = "hidden" name = "user" value = "test"/>
<input type = "hidden" name = "pwd" value = "test"/>
<p>Enter your name, feedback, score</p>

any tips/advice on how to fix my code? the problem i think is in the javascript... will greatly appreciate any help thanks!! Please help, I'm getting this error, Object expected, Code: 0 in Internet Explorer (not in Firefox, though). Here is the link to the page: http://www.uatparts.com/miva/merchan...Category_Code= I'm worried that my customers might shy away and not buy from me when they see this error. What do I need to do in order to stop this error from appearing? Note: I tried including the code in this thread but it was too long, the forum wouldn't let me. I have put this together and it looks to me like it should work but when i ht submit it does nothing, no error or anything, which makes it hard for me to diagnose. You all are much more experienced minds and may look at it and see my error right away (at least thats what im hoping) the point of this project is a form that will post(including pics) to a google spreadsheet. it may be i need to post this in the ajax forum, but its at least partially js so let me know thank you so much for your help all Code: <!DOCTYPE html>

I might as well mention the SOP (same origin policy) here that governs which URLs you are allowed to contact. Hey guys, I've been learning Javascript for a few days using code academy. I've come across this issue, and I'm not sure what exactly I'm doing wrong. Any help would be great. // Check if the user is ready to play! confirm("I am ready to play!"); var age = prompt("What's your age?"); if (age < 13) { console.log("I take no responsiblity, but you are allowed to play") } else { console.log("Have fun!") } console.log("You are at a Justin Bieber concert, and you hear this lyric 'Lace my shoes off, start racing.'") console.log("Suddenly, Bieber stops and says, 'Who wants to race me?'") var userAnswer = prompt("Do you want to race Bieber on stage?"); if userAnswer === "yes" { console.log("You and Bieber start racing. It's neck and neck! You win by a shoelace!"); } else { console.log("Oh no! Bieber shakes his head and sings 'I set a pace, so I can race without pacing.'"); } Hi there, I'm trying really hard to find the solution to this error I am getting in java. Im using blue j. I have a feeling its something other than just braces missing somewhere, I have looked carefully and I'm just having bad luck!! I cant proceed to the next stage of my code unless I get this bit perfected with no syntax errors. I really really appreciate someone helping me out. Code: import java.util.Scanner; import java.awt.Color; /** * Write a description of class stage2 here. * * @author (Gayethiri Guruthevan) * @version (Version 1.0) */ public class stage2 { public static void main(String[]args) { final int WIDTH = 500; // width of the sheet in pixels final int HEIGHT = 500; // height of the sheet in pixels int x; // the x-coordinate int y; // the y-coordinate String direction; // the direction chosen // Create a Scanner object for keyboard input. Scanner keyboard = new Scanner(System.in); // 1. Ask the user for the ant's x-coordinate System.out.print("Enter your ant's x-coordinate: "); x = keyboard.nextInt(); // 2. If the x-coordinate is outside the allowed range, // print an error message and exit if(x < 0 || x > WIDTH-1) { System.out.println("The x-coordinate must be between 0 and " + (WIDTH-1)); System.exit(-1); } // 3. Ask the user for the ant's y-coordinate System.out.print("Enter your ant's y-coordinate: "); y = keyboard.nextInt(); // 4. If the integer is outside the allowed range, // print an error message and exit if(y < 0 || y > HEIGHT-1) { System.out.println("The Y-coordinate must be between 0 and " + (HEIGHT-1)); System.exit(-1); } // 5. Ask the user for the direction System.out.print("Enter the direction the ant is facing: "); direction = keyboard.next(); System.out.print("How many steps should the ant take?: "); int numStepsToTake = keyboard.nextInt(); for(int i=0; i<numStepsToTake;i++) { if (direction.equalsIgnoreCase("DL")) { y+=1; x-=1; } else if (direction.equalsIgnoreCase("DR")) { y-=1; x+=1; } else if (direction.equalsIgnoreCase("D")) { y-=1; } if (direction.equalsIgnoreCase("U")) { x+=1; } else if (direction.equalsIgnoreCase("UR")) { y+=1; x+=1; } else if (direction.equalsIgnoreCase("UL")) { y+=1; x-=1; } else if (direction.equalsIgnoreCase("L")) { x-=1; } else if(direction.equalsIgnoreCase("R")) { x+=1; } else { System.out.println("That is incorrect please enter the right direction"); } // "Wrap" the x and y-coordinates if the ant has walked over the edge of the paper if(x < 0) { x += WIDTH; } else if(x > WIDTH-1) { x-=WIDTH; } if(y < 0) { y += HEIGHT; } else if(y > HEIGHT-1) { y-=HEIGHT; } //Here is the new method for antart.

Can anyone see why that is causing an error? Let me know if you need to see any more of the code Hi everyone In the below code i tried to write java scirpt in action attribute of form tag in html . Why i wrote that was i want to get the scirpt variable as a part of the url of the target page . I also tried using the location.href="targetpage?value="+value . But It is not redirecting to targetpage because of the action attribute in the form tag. And if we use location.href without action attribute only that script variable was posted and all other remaining textboxes and other form items are being not posted ..

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'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.

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. Hi guys.. I really need a bit of help.. is anyone looking at this good with JS?
