JavaScript - Simple Coding Java/asp
I need some help with some simple coding.
I'm editing a website of parameters at work and I have two text boxes that are beside each other. The second text box has a label that shows with it. The second text box and label doesn't need to show unless the first text box has something keyed into it. Could somebody help me with this javascript? showing already:::::::::::::::: dont show until txtbox1 is typed txtbox1 ::::::::::::::::::::::::: lbltxtbox2 : txtbox2 Any help would be greatly appreciated. Thanks Similar TutorialsIm having problems with the following code and not sure why it only seems to be a problem when i call for the amount1 variable in the discountedPriceString variable it returns as undefined. but if i just request amount1 in the alert it works fine. Could someone just explain where i have gone wrong Thanks Code: <script> DISCOUNT_RATE = 0.25; var price = parseFloat(prompt('Enter the normal price','0.00')); var discountedPriceString = 'The sale price is $' +amount1 ; var amount1 = ''; // Apply the discount to the price discount1 = price * DISCOUNT_RATE; amount1 = price - discount1 // Add the new price to the string using toFixed() amount1 = (amount1.toFixed(2)); alert(discountedPriceString); </script> Can Someone please help me with the script for making this work. This is a assignment I am having trouble with the required codes bring up a discount box displaying the output details dependent on the discount code used. I Belleive the While operator is used for this can someone please help me?I no my codes are probably all wrong but am desperate for help thanks For this part of the question you can assume that the user always inputs one of the three correct codes, FSSAVE, ISSAVE and SOSAVE. If (Discount code entered is FSSAVE) give discount one else if (discount code entered is ISSAVE) give discount 2 else if (discount code entered is SOSAVE) give discount 3 var discount; fSSAVE; iSSAVE; sOSAVE fSSAVE = 20p iSSAVE = 30p sOSAVE = 40p discount = window.prompt('Please enter a discount code,' Here'); Hey, so I have successfully used this tutorial; http://articles.sitepoint.com/articl...y-javascript/3 to create a web page that "smoothscrolls" down to a certain point of content on the page. So, I know the java works! My problem is, I have changed the website to be along the X axes and not the Y, so instead of it scrolling "down" the page, I would like it to scroll from left to right. i.e on the X axes not the Y. Is there anyway of doing this by editing that java file? All my buttons work and display the correct part of the website, but the java doesn't work slidiing sideways. Thank you in advance! Darren Hey guys, Here's the program. Quote: import java.util.Random; import java.util.Scanner; public class HighLowGame { public static void main(String[] args) { Random rand = new Random(); int numberOfTries = 0; Scanner input = new Scanner(System.in); char repeat; char ans; int guess; boolean win = false; do { System.out.println("Pick a number between 0 and 10: "); guess = input.nextInt(); numberOfTries++; int numberToGuess = rand.nextInt(10); if (guess == numberToGuess) { win = true; System.out.println("Congratulations you have won!"); } else if (guess > numberToGuess) { System.out.println("Your guess was high try again"); } else if (guess < numberToGuess) { System.out.println("Your guess was low try again"); } System.out.println("The number was " + numberToGuess); System.out.println("You guessed the number in "+ numberOfTries + " attempt(s)"); System.out.println("New game? 1 for Yes, or any other number to quit "); ans = input.next().charAt(0); } while (ans == 1); } } Two questions, why doesn't my program let me keep putting in numbers until I guess the right one? What is wrong with my loop? Pressing 1 should repeat the program, any other number should close. Thanks! Hello, I am trying to create simple Java Script form that will open a URL based on the contents entered into the form. The form shall consist of only a text box and submit button. A user will enter XXXX in the text box and click submit. The form would then load a URL consisting of http://www.company.com/XXXX I know this can be done because I had a code like this a few years back but I have lost it. I've been searching for over an hour, trying to figure this out. Any help would be grately appreciated. Thanks! Hello all, As I am new to java scripts, I usually solve thing with trial and error. What I need is a very simple java script for a count down timer, after searching here I found this: ---------------------- Code: <font style="font-size:72px" color="#FF0000" face="Arial"> <script type = "text/javascript"> var page = "http://www.google.com"; //The page to redirect to function getSeconds() { startTimer (3); // 36 hours } var timeInSecs; var ticker; function startTimer(secs){ timeInSecs = parseInt(secs); ticker = setInterval("tick()",1000); tick(); // to start counter display right away } function tick() { var secs = timeInSecs; if (secs>0) { timeInSecs--; } else { window.location = page; // stop counting at zero // and start again if required } var hours= Math.floor(secs/3600); secs %= 3600; var mins = Math.floor(secs/60); secs %= 60; var result = ( (mins < 10) ? "0" : "" ) + mins + ":" + ( (secs < 10) ? "0" : "" ) + secs; document.getElementById("countdown").innerHTML = result; } </script> <body onload = "getSeconds()"> <span id="countdown" style="font-weight: bold;" ></span> ----------------------------- I modified some stuff, as I defined the font face and size, the color as well, and I added a var to open a certain page when the time is over (as I said before, all these modifications came right with trial and error). So, is that script good? or are there better scripts that do the same job? And, can someone please provide me with a script that does the same functionality of the script I mentioned but instead of showing digits it shows: 01 minutes 31 seconds ? Thank you so much. I imagine this would be very simple for someone who knows javascript. I want to have three fields. First field is "posted speed limit", second field is "actual speed" and third field will be the output field. All the script needs to do it subtract the posted speed from the actual speed and add a ZERO to the end; which is the amount of the speeding ticket. The minimum fine is $100, however. So, 5 miles over the speed limit would be $100 (minimum value) 15 miles over the speed limit would be $150 (add a zero) 35 miles over the speed limit would be $350. etc. I know very little Javascript, if anyone could help me out with this, I'd appreciate it. Thanks, Sean I'm new to coding, And would like to know if java is capable of: Playing a sound file when a name or word is seen on the screen. Or, In this case on a windows sidebar gadget. Thanks ok, so, I honestly have no clue why it wont work.. I'm workin in html and I put some javascript code(im learnin) so here it is, please help! <script> code = 0 function mf() { code += 1 if (code >= 1) { code = 0 {document.getElementById("test").innerHTML = "I have changed";} } else { code = 1 {document.getElementById("test").innerHTML = "Click below to change me!";} } } </script> <p id = "test">Click below to change me!</p> <button type = "button" onclick = "mf()">click here!</button> I have been trying to learn java coding from a book and have run into a coding question that I'm confused about. Can someone help? I have a one dimensional array of positive integers. I'm trying to create another array with the same length and scan the original array for finding the maximum integer. I am then needing to copy that maximum integer in first position of the created array and set the maximum integer in the original array to zero. For second round, I need to write code to find the maximum integer in the original array and copy that in second position of created array and set the maximum integer in the original array to zero. I need to repeat this until all numbers in original array is zero. My created array should be sorted in positive integer numbers. I need to write this sort method that accepts a one dimensional array of integers that return the sorted array testing this method using the main method. What is JAVA? From where I can learn. Please guide me the best institution that is teaching JAVA in the world. Any online tutorial or site where I can get online material. I am not familiar with this program nor i have any idea. I am waiting for your response because i want to start it immediately. hi i want to implement this java script . This is the Original Java script page .

} }; Im writing this code for a gas station program. I have been writing and improving my code for about 3 weeks now and its quite long. I have about classes , customer class, office class and a gas pumps classes. I need help on how to get started on finding the total output at the end of the day. Conceptually i know what i have to do but I don't know where to begin writing the code. I think each time there is a new customer i should add the amount of fuel purchased to a new total fuel purchases variable in the gas pump class. If any one could give me some advice or tips on my theory it would be great ! Should I create a method or can i be done without one. Code: import java.util.Random; import java.util.Scanner; public class Customer { private String carTag; private double gasPurchased; private int gasType; public Customer () { Random gen = new Random ( ); carTag = ""; for (int i = 1; i <= 6; i++) { //a random number between 48 and 90 int code = gen.nextInt (43)+ 48; if ((code <= 64) && (code >= 58)) { i--; continue; } carTag += ((char)(code)); } System.out.println ("a car arrives; tag number:" + carTag); } public int getGasType () { Scanner inputDevice = new Scanner (System.in); //1:regular, 2:plus, 3:premium System.out.println ("enter type of gas to buy " + "(1:regular, 2:plus, 3:premium): "); gasType = inputDevice.nextInt (); return gasType; } public double getGasPurchased () { Random gen = new Random (); gasPurchased = gen.nextDouble ()* 50; return gasPurchased; } public String getCarTag () { return carTag; } Code: import java.util.Random; public class Office { public static void main (String [ ] args) { double regularTank = 1000; double plusTank = 1000; double primiumTank = 1000; GasPump pump1 = new GasPump ( ); GasPump2 pump2 = new GasPump2 ( ); Random gen = new Random (); //asuumint gas tanks always have gas, will upgrade later do { int whatHappens = gen.nextInt (100); if (whatHappens == 5) { System.out.println ("gas station closed"); break; } else if ((whatHappens % 10) == 0) { if (pump1.pumpAvailable ()) pump1.customerArrival (); else System.out.println ("a new customer arrives at pump 1, but is turned away, gas pump is busy"); } else { if (pump1.pumpAvailable ()) System.out.println ("no customer; waiting........."); } if (!pump1.pumpAvailable()) { if (pump1.updateClock () == 0) pump1.saleComplete (); } } while (true); do system.exit () Code: public class GasPump { final private double REGULAR_PRICE = 3.15; final private double PLUS_PRICE = 3.5; final private double PREMIUM_PRICE = 4.5; final private double HOSE_FLOW_RATE = 0.85; private double totalPayment; private Customer who; private int timeLeftToFinish; private int gasType; private double gasPurchased; private String carTag; public GasPump () { who = null; totalPayment = 0; timeLeftToFinish = 0; } public void customerArrival () { who = new Customer (); System.out.println ("welcome to jack's gas station PUMP 1 "); gasType = who.getGasType (); gasPurchased = who.getGasPurchased (); timeLeftToFinish = (int)(gasPurchased/HOSE_FLOW_RATE); System.out.println (timeLeftToFinish + " total time units needed for this transaction..."); carTag = who.getCarTag (); } private void printReceipt ( ) { System.out.println ("****Sale Receipt"); switch (gasType) { case 1: System.out.println ("regular gas"); break; case 2: System.out.println ("plus gas"); break; case 3: System.out.println ("premium gas"); break; } System.out.println ("gas amount: " + gasPurchased + "\ntotal payment" + totalPayment + "\nthank you"); System.out.println("Pump has " + regularTank()); } private void resetPump ( ) { who = null; totalPayment = 0; timeLeftToFinish = 0; } public int updateClock () { timeLeftToFinish--; System.out.println (timeLeftToFinish + " time units left to finish "); return timeLeftToFinish; } public void saleComplete ( ) { switch (gasType) { case 1: totalPayment = REGULAR_PRICE * gasPurchased; break; case 2: totalPayment = PLUS_PRICE * gasPurchased; break; case 3: totalPayment = PREMIUM_PRICE * gasPurchased; break; } printReceipt ( ); resetPump ( ); } public boolean pumpAvailable () { return (who == null); } } I'm not really good with javascript and need help with a problem. I'm creating a pop-up window that goes to another site but sends the url it's coming from in the url it's going to. Ok here's what I have if that's confusing. Code: <head> <script type="text/javascript"> function popupwin(url) { var width = 650; var height = 250; var left = (screen.width - width)/2; var top = (screen.height - height)/2; var params = 'width='+width+', height='+height; params += ', top='+top+', left='+left; params += ', scrollbars=1'; newwin=window.open(url,'popupwin', params); if (window.focus) {newwin.focus()} return false; } </script> </head> <body> <a href="javascript: void(0)" onClick="popupwin('http://example.com/check.php?id=http://$_SERVER[SERVER_NAME]$_SERVER[REQUEST_URI]'); return false;">Centered popup window</a> </body> Now that above code works fine in most cases and on most sites. The problem is that one forum I've tried it on has a seo mod which means the php comand $_SERVER[REQUEST_URI] isn't the same that's in the address bar. Instead of showing Code: http://sitename.com/forum/main-forum/1-test-post-title-some-list.html it's showing Code: http://sitename.com/forum/showthread.php?p=1 After Googling I know that document.write(location.href) will give me the exact url of the seo url as it appears in the address bar which is what I want. Can anyone show me how to combine document.write(location.href) with my code. I know it's probably easy for most but I only really know basic html and php and I'm only new to javascript. Thanks in advance. |
