JavaScript - Creating Math Sheet Generator
I have been asked by a friend to create a math sheet generator for their child, however i don't have a clue where to start with javascript.
Similar to this.. http://cemc2.math.uwaterloo.ca/mathf...sheetgen.shtml It doesn't need to be advanced as that as all i'm looking for is how to create the sums. If someone could help either by informing me where to start or even an online tutorial i would be extremely greatful! Many thanks, James Similar TutorialsHello, I want to make myself a tool where if I paste in multiple lines of text cells (most likely from Excel, but that shouldn't matter), it will generate the pre-file extension and the ending file extension and echo it back on the page (not saving or storing, just temporary). I have no trouble creating a form in javascript (or php) that could input the extension automatically for 1 item, but I was wondering if it's possible for a list of multiples within the same form box? For example, I want to copy and paste this set of assets from excel into my form box: asset1 asset2 asset3 asset4 asset5 asset6 asset7 Submit it and receive an echo on the page of this. The stuff in bold will always be the same, just wrapped around the asset i inputted into the form. /f1/blah/example/asset1.xml /f1/blah/example/asset2.xml /f1/blah/example/asset3.xml /f1/blah/example/asset4.xml /f1/blah/example/asset5.xml /f1/blah/example/asset6.xml /f1/blah/example/asset7.xml I was able to create the form for 1 item, but not multiple. I just started to learn... so please don't be mad or flame me!! I am just wondering how difficult it is to learn to make this. Thanks! I've studied Javascript some and have searched the web for similar codes but I'm still struggling with creating a mock pay slip generator and I'm hoping someone can make one for me or show me a generator/calculator similar to this: A user should be able to enter his or her name and gross pay in input fields and have the take home pay calculated with federal tax (20%) and state tax (10%) incorporated. There should be a "Generate Pay Slip" button and a "Reset" button. Alert displays should be used for each component and when "Generate Pay Slip" is pressed, an alert should appear saying something like "John's Smith take home pay is 1000 dollars." There should lastly be a web page displaying the break up in text. I'm not sure how demanding actually doing this would be for a Javascript expert... if it is I sure could use some advice as to how to learn how to do this. I run a website for a skittle league and am looking to create a form to allow teams to sumbit results on line. I'm not an expert on Javascript, the code I've created so far allows the user to enter the player name and score for one team and calcutate the total. However, I'm having problems duplicating this for a second team, and would like to remove the Get Total button (i.e. Auto Calculate total). Can anyone advise how I can do this. The Code I have so far is <html> <head> <script type="text/javascript" language="javascript"> function getTotalH1(oForm) { var field, i = 0, total = 0, els = oForm.elements; var fieldnames = ['PSH1' , 'PSH2' , 'PSH3' , 'PSH4' , 'PSH5']; for (i; i < fieldnames.length; ++i) { field = els[fieldnames[i]]; if (field.value != '' && isNaN(field.value)) { alert('Please enter a valid number here.') field.focus(); field.select(); return ''; } else total += Number(field.value); } return ' ' + total; } </script> </head> <body> <form> <div align="center"><table border="0" cellpadding="2" cellspacing="0" width="305"> <col width="250" align="left"> <col width="42" align="center"> <tr> <td><input type="text" name="PNH1" size="35"> </td> <td><input id="PSH1" type="text" name="PSH1" value="" size="4"></td> </tr> <tr> <td><input type="text" name="PNH2" size="35"></td> <td><input id="PSH2" type="text" name="PSH2" value="" size="4"></td> </tr> <tr> <td><input type="text" name="PNH3" size="35"></td> <td><input id="PSH3" type="text" name="PSH3" value="" size="4"></td> </tr> <tr> <td><input type="text" name="PNH4" size="35"></td> <td><input id="PSH4" type="text" name="PSH4" value="" size="4"></td> </tr> <tr> <td><input type="text" name="PNH5" size="35"></td> <td><input id="PSH5" type="text" name="PSH5" value="" size="4"></td> </tr> <tr> <td><input type="button" value="Get Total" onclick="total.value=getTotalH1(this.form)" /> <input type="reset" /></td> <td><input id="total" type="text" name="totalh1" value="" readonly="readonly" size="4"></td> </tr> </table></div> <br><br> </form> </body> </html> thanks Hi. I have a problem with a random link generator within a DIV. When I try it on my desktop it works fine, but does nothing once I upload it to the website. I'm not sure how to explain what happens, but here is it, more or less: The website is this: http://torcacita.atspace.com Via an Ajax script, http://torcacita.atspace.com/menu.html is loaded into DIV "menu". Here's the script: <script type="text/javascript"> ajaxpage('menu.html', 'menu') //load "menu.html" into "menu" DIV </script> Well, there's another load of stuff inside the <head> tag. You may see it from the main page source code. Anyway, if you go to the menu.html, the link generator will work there as it is intended; however, if you try it from the main page, it won't do anything. But people are not suppossed to go to menu.html. They are suppossed to load it from the index.html (I mean, plain http://torcacita.atspace.com) So, here's the link generator code: --------------------------------- <script type="text/javascript"> function randomlinks(){ var myrandom=Math.round(Math.random()*9) var links=new Array() links[0]="http://www.javascriptkit.com" links[1]="http://www.dynamicdrive.com" links[2]="http://www.cssdrive.com" links[3]="http://www.codingforums.com" links[4]="http://www.news.com" links[5]="http://www.gamespot.com" links[6]="http://www.msnbc.com" links[7]="http://www.cnn.com" links[8]="http://news.bbc.co.uk" links[9]="http://www.news.com.au" window.location=links[myrandom] } </script> <form> <input type="button" value="Lo Que Sea" onClick="randomlinks()"> </form> --------------------------------- I believe this could be solved if I could target the generator to the whole window, 'cause maybe it's trying to open the new page inside the DIV. Well, I don't know... So, what do you think? Could somebody help me? I have a piece of code that randomly picks a line from a preset list and displays it whenever the page is loaded. I'm using it to generate random quotes on my pages. At the moment, there seems to be a good chance that when the page loads no quote appears at all, just a blank space. Anyone know why this could be happening? the code I am using is: Code: <script type="text/javascript">
q0= "<img src=\"images/quotes/01.png\" />";
q1= "<img src=\"images/quotes/02.png\" />";
q2= "<img src=\"images/quotes/03.png\" />";
q3= "<img src=\"images/quotes/04.png\" />";
q4= "<img src=\"images/quotes/05.png\" />";
q5= "<img src=\"images/quotes/06.png\" />";
q6= "<img src=\"images/quotes/07.png\" />";
q7= "<img src=\"images/quotes/08.png\" />";
q8= "<img src=\"images/quotes/09.png\" />";
q9= "<img src=\"images/quotes/10.png\" />";
q10= "<img src=\"images/quotes/11.png\" />";
q11= "<img src=\"images/quotes/12.png\" />";
var ran_unrounded=Math.random()*11;
var ran_number=Math.round(ran_unrounded);
document.write(eval("q"+ran_number));

Hey guys. It's been a while since I was last here but I'm having a few problems. I'm building a random word generator form for a friend but my knowledge of JS is limited. I have found a script to randomly generate a word at the click of a button.

The script above will allow me to do separate boxes with their own buttons. If anyone can help it would be greatly appreciated. Foster Hi there... actually i am working on a project "random password generator". What basically is to be done in this project is to generate user password for the username randomly he has provided. Then, this password is to be stored in a text file in the following manner UserName Password ABCD JU12H6 Sdjksj HJudfdsfd Now my problem is that every time I just try to generate a new password, either a new file is made or the heading is rewritten again and again or if I just try to change the variables true and false, then the username and password headings are not printed. Please help. If someone knows how to do this using if-else method then please tell me, how it can be done? The code is attached. Code: <html>

Hello. I'm new here and learning JavaScript. Could you help me to write very simple script to auto generate user name ? From any letters. Min 6 - Max 10. Like: "jgFJFJ" "KGHGyvk" etc. Please help. I know i don't have any code but does anyone have ideas how to start one? Preferably not squares hexes as each piece.
Hi, my assignment is to create an online quiz with a random image generator. I have created my online quiz using 5 linking files and everything works great. My only problem is getting the images to show up on my quiz. All I get is the filename with a red X. Which the files do show up at random when I refresh, so I know that part is working. I just don't know what I am missing to get the actual picture to show up. Please take a look at my code below and see if I am missing anything. Please keep in mind this isn't the whole code as I have different linking files for this assignment. Thank you in advance. Code: <?xml version = "1.0" encoding = "utf-8"?>

Hey I'm somewhat new to the javascript world because 95% of my website is HTML so, if you will, I need help writing the javascript for a Random Question Generator...basicly all I have is Code: <script type="text/javascript"> var Q = new Array() Q[1] = "What is your favorite color?"; Q[2] = "What is your favorite animal?"; Q[3] = "What is your favorite place?"; </script> In the real one, there will be about 20 questions and I will need it to choose a quetion randomly out of the 20. As I said i am a beginer so as simple as possible would be great. Thank You for your help in advance Hi all again, Firstly thanks to Philip M for getting me this far but i still have a few quirks that i'd like to get around. Its a price generator with 3 options. User selects an option from a drop down, inputs "number of words" and hey-presto the price appears. That works superbly well but what would be really cool is if after someone gets a price they then would like to select a different option in order to see a new price. At the moment it means selecting another option and re-entering the number of words and then clicking in the price box to get the new result. Is there anyway to make that price change automatically (as if by magic even) if either the "option" or "number of words" is changed I have a sneaky suspicion that Philip M will come to the rescue again but should anyone else have a view that would be great also. Thanks as always in advance, Phil Code: <head>

Thanks, Fizz Trying to develop a small app for my site. What is the code to generate a random # of lines (1 min - 5 max) and a random phrase for each line sourced from a multidimensional array? These also need to be unduplicated (so I won't have quote 1 be on lines 1 and 4). How do I prevent random duplication with the generated lines of text? Thanks!
Hi all. I hope that everyone is fine and doing well. This is something of an annual visit for me. You guys helped me enormously with the code below. It is a price quote generator that takes a number (entered by the client) and depending on the package selected, produces a price quote. As I said, it works really well, but it's time for me to expand my business overseas. At the moment, I display the price as a single currency, but I would like for clients to be able to select (maybe from a drop down list in the answer field) any one of 4 different currencies (i.e., GBP, USD, EURO, MYR). The different exchange rates don't need to be up to the minute accurate. I'm quite happy to go in to the code and update them weekly or as required. I have attempted to research different ways of doing this, but as my needs are quite unusual and my brain really can't wrap around the ins and outs of java script, i'm here again begging with my cap in hand for help. To see this code in action as it stands, please go to www.grammarproofing.com Code: <head>

Thanks in advance for any help offered. Regards as always, Phil Below is a function to download a set of images from a website based on the width, height and levels of the image which is obtained from the following config file: http://api.gigapan.org/beta/gigapans/10826.json If I use 10826 as the gigapanId, I get a width of 50944, height of 14269 and levels 9 for the below variables. What I am trying to do is rather then use this as a function, I want to convert this into a basic script which just outputs to the screen all the possible urls that images would be at based on the width, height and levels of the source gigapanId. Any thoughts on how I should do this? Should I be using javascript to do this or would another language be better for this? Thank you so much for any help! Chris Code: GigapanTileSource.prototype = new Seadragon.TileSource();
GigapanTileSource.prototype.constructor = GigapanTileSource;
function GigapanTileSource(gigapanId, width, height)
{
Seadragon.TileSource.call(this, width, height, 256, 0, 8);
this.gigapanId = gigapanId;
//alert('gigapanid:'+gigapanId);
this.getTileUrl = function(level, x, y)
{
if (level >= 8)
{
level = level - 8;
}
var url = 'http://share.gigapan.org/gigapans0/' + this.gigapanId + '/tiles';
var GC_TILE = ["0", "1", "2", "3"];
var name = "r";
var bit = 1 << level >> 1;
while (bit)
{

(Instead of just one). Could someone pls alter the code to allow me to do this please ... I also hope to keep the js file off the main html page. (naming the file list.js) Could someone also indicate how I do this. Hopefully these questions are easy if you know how etc. So far i havent been able to do it... Would be good if i could add a line to prevent duplicate randomly drawn links appearing in the list of eight.... thanks very much if you able to indicate it..... Hi, I have a 'Register' page on my site. When someone registers to my website, I would like to make it necessary to have a div box which generates a random number/letter, which is linked to a text field where the user has to match the generated output. I've been sitting here wondering which would be the best route to take regarding completing this. I was thinking about using charAt() method. Could anybody please possibly give me some tips for generating random letter/numbers? Possibly would I create a string containing "ABCDE....Z0123456789", then use the charAt method to find a character at a certain index position? If so, would I need create something which generates a random index position? Any help would be fantastic, thank-you. Ok, so I decided to make an Experience Generator for my site. I started simple by making one that uses a prompt. First it prompts for your level, then it multiplies it by using a random number function. This code below. Code: <html>
<head>
<title>Experience Generator</title>
<script type="text/javascript">
var A= Math.round(Math.random()*100);
var B= prompt('Place your Level Here');
function Expearned()
{
document.write(Exp=B*A);
document.write(" Experience Points Earned");
}
</script>
</head>
<body>
<a href="javascript:Expearned()">Experience Calculator</a><br />
</body>
</html>
Then, I thought... I don't like using prompts. So, how about using text inputs and buttons instead. I then created this code. Code: <html>
<head>
<title>Experience Generator</title>
<script type="text/javascript">
var A= Math.round(Math.random()*100);
var B= input();
function Expearned()
{
document.write(Exp=B*A);
document.write(" Experience Points Earned");
}
</script>
</head>
<body>
<FORM ACTION="#" NAME=LeveltoExp></FORM>
Enter Level
<INPUT TYPE=TEXT NAME="Enter Level" SIZE=3>
<BR><BR>
<INPUT TYPE=BUTTON VALUE="Earn Experience"
ONCLICK=" Expearned()
+ 'is '
+ ' Experienced Earned'">
<BR><BR>
</FORM>
</body>
</html>
BUT this code pulls up and error at the line of var B.. What I am trying to do is pass the form to the var B and then goes on from there to do the Experience Generator. Can anyone Help me???? I've looked everywhere for a random number generator which doesn't repeat. Tried loads and none have seemed to work. I'm making a quiz, 5 questions so far. This button, in html, generates the next random Q: Code: <input type="button" value="Next (random)" name="B0" onClick="rangen();generatequestions();qnum()"><br><br> Lower down in the javascript (in the body), here is the rangen() function: Code: function rangen(){
whichone=Math.floor(Math.random()*5)
}
But I need a random generator which fires them off only once. For reference, here is the next bit (not so important): Code: var whichone=1;
var q=1;
var tempmn=document.instantquiz.thequestion
function generatequestions(){
if (q>0)
q=q++
if (loop>0)
loop=0
document.instantquiz.theresponse.selectedIndex=0
if (!document.instantquiz.cmode.checked||whichone>=total+1||whichone<=0)
document.instantquiz.thesolution.value=''
if (whichone>=total+1)
tempmn.value="End of quiz"
else{
tempmn.value=whichone+")"+question[whichone]+"\n\n"+"a)"+eval('choice'+whichone+'[1]')+"\n"+"b)"+eval('choice'+whichone+'[2]'
)+"\n"+"c)"+eval('choice'+whichone+'[3]')+"\n"+"d)"+eval('choice'+whichone+'[4]')
if (document.instantquiz.cmode.checked)
document.instantquiz.thesolution.value=solution[whichone]
}
}
Anyone have suggestions for a non-repeating random number gen which will work? Even the one now seems to have some slight error associated with it. The one's ive tried so far haven't worked.. |
