JavaScript - Code Help Needed By New Javascript Student
Similar TutorialsI am still learning javascript so forgive me if this question is a bad one, I am making scripts for Greasemonkey for a website I am a part of. One of the developers recently commented out (in the source code) a feature that was available before. It is a Football MMORPG game and it used to show college players 40 times but over the past month he commented out the tag that held the script function. I want to know if i can either A) write a js code that can remove the comment tag in the source code or B) write a code that will just add another tag under that and have that js function that was commented out valid. I tried something but ended up just having that function pasted onto the page instead of having it put into the source to have it read by the rest of the data.. here is what im talking about <TABLE width=800 cellspacing=0> <tr> <td colspan=3 style="FONT-SIZE: 11pt"> <b>Hometown:</b>Fort Hunt, VA<br> <b>Height:</b>6-0<br> <b>Weight:</b>206<br> <!--b>40 Time:</b><if rs("team_id")>0 or bRated then><=formatnumber(rs("forty"),2)><br><end if --> i just want to see if there was any way to just delete the comment out of it so i can get this feature again is all. Any help would be awesome... and sorry for the long post I have a vendor delivered java script code that I am currently customizing. The original code involves a user when selects a "check box" option value , a small function is called titled "VerifyAcctType". Currently when a user selects the check box some values are defaulted into the form. Now to this function code below i have to add logic when user selects the same check box option FIRST a small pop up window should appear which lists two radio buttons"I Agree to terms" and "I do not agree to terms" options , user need to select one of the options in the pop up to proceed. If the user agrees to terms then the control should go back to the "VerifyAcctType" function and proceed with remaining steps like before else if the user selects "I do not agree" the logic should not proceed further in "VerifyAcctType" function. Here is the current code tied to VerifyAcctType function ============================================== function VerifyAcctType(win,type) { var AcctType var ThisWindow var ThisForm if (win == "ADD") { ThisWindow = AddAccountWind ThisForm = AddAccountWind.document.addform } else if (win == "CHG") { ThisWindow = ChangeAccountWind ThisForm = ChangeAccountWind.document.chgform } if (type == "P") { <<I NEED NEW CODE HERE FOR THE POPUP>> Maccttype = type ThisForm.description.value = "My Company" ThisForm.comp_id.value = "1234567" ThisForm.comp_id.disabled = true } else { Maccttype = type ThisForm.description.value = "" ThisForm.comp_id.value = "" ThisForm.comp_id.disabled = false } } I am a java script beginner , any help is appreciated. hey guys. i need a js code that redirects to a flash page or to a non flash page after detecting the browsers plugin abilities and if it has flash or not. any help would be appriciated. cheers I have a javascript program I'm trying to write for an introductory javascript class. The book is absolutely terrible and I've found I have a very weak grasp of how javascript functions work but I have an exam coming up and I'm getting desperate for help so I'm posting here hoping someone can help me get my head wrapped around this thing. The code is a simplified game of 21. It should randomly generate two cards for the dealer and two for the player, then display the total to the player and allow them to choose whether or not to take another card. It then decides who won. I'm including the script below: Code: <script type="text/javascript">
/*Declare Variables*/
var dealer = 0;
var player = 0;
var dealerPoints = 0;
var playerPoints = 0;
var rNum = 0;
var rPlayer1 = 0;
var rPlayer2 = 0;
var rDealer1 = 0;
var rDealer2 = 0;
var hitMe = " ";
function playGame()
{
while((playerPoints < 200) && (dealerPoints < 200))
{
/*Generate 2 random numbers between 2 and 11 for the player*/
rPlayer1 = Math.floor((Math.random() * 10 + 2))
rPlayer2 = Math.floor((Math.random() * 10 + 2))
rDealer1 = Math.floor((Math.random() * 10 + 2))
rDealer2 = Math.floor((Math.random() * 10 + 2))
/* Find Players Total*/
player = (rPlayer1 + rPlayer2);
/* Find Dealers Total*/
dealer = (rDealer1 + rDealer2);
/*Display player total*/
while ((player <= 21) && (dealer <= 21))
{
hitme = prompt("You drew a " + rPlayer1 + " card and a " + rPlayer2 + " card for a total of " + player + ". Do you want another card?");
if (hitMe == "yes")
{
rPlayer1 = Math.floor((Math.random() * 10 + 2));
player = (player + rPlayer1);
alert("You drew a " + rPlayer1 + " card for a total of " + player + ".");
}
if ((player <= 21) && (dealer > 21))
{
playerPoints = (playerPoints + player);
alert("Player Wins Hand");
}
if ((dealer <= 21) && (player > 21))
{
dealerPoints = (dealerPoints + dealer);
alert("Dealer Wins Hand");
}
if ((dealer > 21) && (player > 21))
alert("Tie, no points awarded");
}
if ((dealer <= 21) && (player <= 21))
{
if (dealer > player)
{
dealerPoints = (dealerPoints + dealer);
alert("Player total: " + playerPoints + ". Dealer points: " + dealerPoints + ". Dealer wins this hand.");
}
else if (player > dealer)
{
playerPoints = (playerPoints + player);
alert("Player total: " + playerPoints + ". Dealer points: " + dealerPoints + ". Player wins this hand!");
}
else
{
alert("Player total: " + playerPoints + ". Dealer points: " + dealerPoints + ". No one wins this hand.");
}
if (playerPoints >= 200)
{
alert("Player wins game!");
}
else if (dealerPoints >= 200)
{
alert("Dealer wins game!");
}
}
}
}

I am looking for a javascript code for this idea under this message ---------------------------------------------------------------------------------------------------------------------------------------------------- I want to create a kind of shopping website so when you click on a image or text it will add some text to a textarea,, it will include the name of item and price of an item A single letter is taken from each word in the sentence. Unlike before, either the first or last letter is taken. The letter taken is decided by which of the first or last is "greater" (e.g. "b" > "a", "c" > "b", etc.) Here are some examples based on the above rules: "hello" translates to "o" because "o" is greater than "h". "goodbye" translates to "g" because "g" is greater than "e". Full sentence example: "wazdee apple love bic nooo more end" This sentence will decrypt to "welcome". Complete the decryptB function so that it decrypts messages with the new scheme. Here are some examples: var decryptB = function(message) { // Your code here } var result1 = decryptB("wazdee apple love bic nooo more end") console.log(result1) // This should be "welcome" var result2 = decryptB("bria loud fuzu antidote") console.log(result2) // This should be "blue" Reply With Quote 01-20-2015, 09:41 PM #2 Old Pedant View Profile View Forum Posts Supreme Master coder! Join Date Feb 2009 Posts 28,310 Thanks 82 Thanked 4,754 Times in 4,716 Posts See the page http://www.codingforums.com/rules.htm See rule 1.5 We helped you way way too much the last time you asked the first variant of this homework problem. This is really a very simple variation on that. And you don't even include the final version of the code you used last time, so somebody who didn't see the last answers would have to start all over again. Not very friendly to potential responders. What have you *TRIED*? If you came running here without even trying to solve this, shame on you. At least show what you have tried and explain what results you get and, if you can, what you think is going wrong. By the way: How is the user supposed to output an "a" character? You need an answer to that question, methinks. i wold like to get this working. when a user enters 4 grades into the text boxes. it would give them the Avg Grade and also what Mark they got, and if they failed one out put the module they most Repeat and if they passed all out put a smiley face.. This is what i have so far.. Code:
function compute() {
var c = document.getElementById("c").value;
var computer = document.getElementById("computer").value;
var web = document.getElementById("web").value;
var math = document.getElementById("math").value;
document.getElementById("cost").value =
totalCost = (c * 100 + computer * 100 + web * 100 + math * 100 ) /4;
if(cost >=93)
alert(" You got an A+")
else
if((cost >=85)&(grade <93))
alert(" You got an A")
else
if((cost >=78)&(grade <85))
alert(" You got an B")
else
if((cost >=60)&(grade <78))
alert(" You got an C")
else
if((cost >=40)&(grade <60))
alert(" You got an D")
else
if(cost <40)
alert(" You Failed this Module")

var suitArray = ["Hearts","Diamonds","Clubs","Spades"]; var faceArray = ["Ace", - Pastebin.com Doing a school assignment and Im totally stumped, google isnt any help nor is any of these textbooks. I need to tally up the playerhands and dealer hands and display the winner. I can get it to display the value of the current card. eg 7 of diamonds = 7 points but I cannot get it to tally up all the cards dealt. I'm doing a correspondence course on javascript, but the terminology is giving me up-hill and after hour of battling, my Javascript was just a mess. could someone help me with the javascript function. My instruction reads: "Create a web page with 5 text boxes. Assign to each text box's value attribute a value of zero. Add to each of the text boxes an onchange event handler that calls a function named calcAvg() and passes to the function the value of that text box by referencing it's document object, form name, and name and value attributes. Within the calcAvg() function, pass the five parameters to another function, named performCalc(), and assign the returned value to a variable named calcResult, then place the returned value in to another text box with a name averageResult. In the performCalc() function, calculate the average of the five numbers (by adding the five numbers and then dividing the total by 5), then return the result to the calcAvg() function. When you preform the calculation, use the parseInt() function to insure that the passes values are calculated as numbers." Please assist be as kind as to assist me with this project so I can use it as reference to the following projects that follow on the foundation of this one...

Hi I am new to programming and I am trying to write a piece of code, I need the output to be a whole random number, this is what I have up to now : <SCRIPT language = "JavaScript"> //generate a random number greater than or equal to 0.0 and less than 50.0 //and display it in an alert dialogue window.alert("getRoundedRandomNumber: " Math.round + Math.random()*50); </SCRIPT> </HEAD> <BODY> <STRONG>A test of the random number functions <BR></STRONG> <FORM NAME = "randomForm"> <INPUT TYPE = "button" NAME = "randomButton" VALUE ="Display Random Number" ONCLICK = "window.alert(getRoundedRandomNumber(50));"> </FORM> can anyone advise me where I would put the Math.round function and how to make it work ? Thanks in advance HI there.. Can you please give me code in JavaScript to create a student request form for book request from issue section of college Library.. Please help with code... Thanx in advance... Regards, Can someone please suggest a good (and simple) code for password protecting one page on a site? I have a plan room for blueprints on my site. There will be multiple jobs at a given time and I need a page where we can give out a password to get the plans. Once the person logs in with user name and password for that day, he would then see file folders with the name of each job next to it. When he chooses a job, he clicks the folder to display a list of plans. If you can help with this or point me in a good direction, it would be greatly appreciated. Thanks for your help! Hello everyone. I have been trying 2 days straight to figure out how to make this script work. Basically I am trying to have a hidden checkbox with a drop down menu. I want the user to be able to choose 0-9 where 0 the check box will not be checked and 1-9 if picked from the dropdown menu it will automatically check the hidden box. Here is the closest string of code I could find out there to help me figure it out but I am having no luck. The closest I got was....well I never really figured out how to make it work. Can someone please help me? Thanks. <script type="text/javascript"> function checkUncheck (selected) { var checkBox = document.getElementById("box"); if ((selected == 2) || (selected == 3)) { checkBox.checked = "checked"; } if ((selected == 0) || (selected == 1)) { checkBox.checked = "false"; } } </script> <form id="frm"> <table> <tr> <td><input type="checkbox" id="box" checked="false"/></td> <td> <select id="sel0" onchange="checkUncheck(this.selectedIndex)"> <option value="zero">zero</option> <option value="one">one</option> <option value="two">two</option> <option value="three">three</option> </select> </td> </tr> </table> </form> Hi everyone, im no expert in coding but i manage to get this bit of code together using some free source stuff and put in the links to my images ect, the problem now is i need each picture to be different sizes and each one to have a clickable link but i am completely stumped heres the code Code: <html>

Hey folks, Forgive me in advance if this is not the correct place to post this thread. I am a new member to this forum and need a little assistance. I have some script to create a quiz but need a little more detail. Does anyone know some code I can insert, and where to randomize the questions. Secondly if I have a test bank of 100 questions but want to limit the test to 20 questions what code would I need to insert that as well. Any assistance is very much appreciated. thank you. kenster I want to insert a link into an email that opens a new window of a specific size. All of the scripts I find require some code to be inserted into the <head> tag of the page. Obviously this will not work since I am inserting the link into an email. Is there a JavaScript code for opening a popup window that's not dependent on <head> code?
This is the code that I'm presently using: Code: <script language="JavaScript" type="text/javascript">

However, what this piece of code does is that, every radio button gets only 1 point. What I intended is that every subsequent radio button in each <td> garners incremental points by 1. Eg: Q1, 1st radio button gets 0pt, 2nd radio button gets 1pt, 3rd radio button gets 2pt. Does anyone have any idea how to implement that, all help are greatly appreciated! Pretty pretty please help me with this I am running out of time and pulling my hair out with this whole thing. Thanks a million in advance!

But I cant work out how to get rid of it. This is the html it is a transistional XHTML doc type. Code: <div id="slidedom"> <script type="text/javascript" src="js-files/slider.js"></div></script> Then I have the js file which I will have to post all of as I am not sure of the error bit. Code: var variableslide=new Array()
//variableslide[x]=["path to image", "OPTIONAL link for image", "OPTIONAL text description (supports HTML tags)"]
variableslide[0]=['images/sign-1.gif']
variableslide[1]=['images/sign-3.gif']
variableslide[2]=['images/sign-4.gif']
//configure the below 3 variables to set the dimension/background color of the slideshow
var slidewidth='188px' //set to width of LARGEST image in your slideshow
var slideheight='60px' //set to height of LARGEST iamge in your slideshow, plus any text description
var slidebgcolor='#FFF'
//configure the below variable to determine the delay between image rotations (in miliseconds)
var slidedelay=3000
////Do not edit pass this line////////////////
var ie=document.all
var dom=document.getElementById
for (i=0;i<variableslide.length;i++){
var cacheimage=new Image()
cacheimage.src=variableslide[i][0]
}
var currentslide=0
function rotateimages(){
contentcontainer='<center>'
if (variableslide[currentslide][1]!="")
contentcontainer+='<a href="'+variableslide[currentslide][1]+'">'
contentcontainer+='<img src="'+variableslide[currentslide][0]+'" border="0" vspace="3">'
if (variableslide[currentslide][1]!="")
contentcontainer+='</a>'
contentcontainer+='</center>'
if (variableslide[currentslide][2]!="")
contentcontainer+=variableslide[currentslide][2]
if (document.layers){
crossrotateobj.document.write(contentcontainer)
crossrotateobj.document.close()
}
else if (ie||dom)
crossrotateobj.innerHTML=contentcontainer
if (currentslide==variableslide.length-1) currentslide=0
else currentslide++
setTimeout("rotateimages()",slidedelay)
}
if (ie||dom)
document.write('<div id="slidedom" style="width:'+slidewidth+';height:'+slideheight+'; background-color:'+slidebgcolor+'"></div>')
function start_slider(){
crossrotateobj=dom? document.getElementById("slidedom") : ie? document.all.slidedom : document.slidensmain.document.slidenssub
if (document.layers)
document.slidensmain.visibility="show"
rotateimages()
}
if (ie||dom)
start_slider()
else if (document.layers)
window.onload=start_slider
I have taken out the credit, as I have changed it a bit, but will reinstate it later on. All I really need to know is how to define it in the XHTML maybe. Can anyone help? |
