JavaScript - Having Trouble Generating Random Text
New to JS, and not too good at it.
Trying to take some prewritten code and add script that displays some random text. Having trouble with assignment. Instructions are to replace a section of the file I am given with a script element. In the script element I am suppose to declare a variable named tipNum equal to a random integer between 1 and 10 returned by the randInt() function (which I made and have shown below). Then I am suppose to use a series of document.write() methods to write the following HTML code into the page: Code: <h1>Random Tip<br />title</h1> <p>tip</p> (Where "title" is the title of the random text as generated by the tipTitle() function from a external file, and which I did not make; and "tip" is the text of the random tip as genereated by the tipText() function, which is also from the external file, and not made by me) My code for the randInt() function is Code: function randInt(lower, upper) {
var size = ++(upper - lower);
var randValue = Math.floor(lower + size*Math.random());
}
The script I made to display the HTML code is Code: <script type="text/javascript">
var tipNum = randInt(1, 10);
document.write("<h1>Random Tip<br />"+tipTitle(tipNum)+"</h1>");
document.write("<p>tipText()</p>");
</script>
I am getting nothing on my page where the random text should be. Any help or advice would be great, thanks. Similar TutorialsI'm trying to find a much simpler way than this current script I am using to generate and print a random word. I don't want to have to name each word but instead just include a very large list of about 300,000 words that javascript uses to pull a random word out of. Can you please help me out?? The list of words I have is a straight list with no commas or anything. I am currently outputting to a text box, but I am looking to generate words according to users input. For example, a user wants 500 words starting with the letter "b" and is less than 5 characters long appended to the character "de." Any help would be awesome! Even a right direction. I'm also willing to pay some for such a script if need be. Thanks! Here's my code: Code: <SCRIPT LANGUAGE="JavaScript">
<!--
var NumberOfWords = 28
var words = new BuildArray(NumberOfWords)
words[1] = "czarevitch"
words[2] = "brightwork"
words[3] = "verkrampte"
words[4] = "protectrix"
words[5] = "nudibranch"
words[6] = "grandchild"
words[7] = "newfangled"
words[8] = "flugelhorn"
words[9] = "mythologer"
words[10] = "pluperfect"
words[11] = "jellygraph"
words[12] = "quickthorn"
words[13] = "rottweiler"
words[14] = "technician"
words[15] = "cowpuncher"
words[16] = "middlebrow"
words[17] = "jackhammer"
words[18] = "triphthong"
words[19] = "wunderkind"
words[20] = "dazzlement"
words[21] = "jabberwock"
words[22] = "witchcraft"
words[23] = "pawnbroker"
words[24] = "thumbprint"
words[25] = "motorcycle"
words[26] = "cryptogram"
words[27] = "torchlight"
words[28] = "bankruptcy"
function BuildArray(size){
this.length = size
for (var i = 1; i <= size; i++){
this[i] = null}
return this
}
function PickRandomWord(frm) {
var rnd = Math.ceil(Math.random() * NumberOfWords)
// Display the word inside the text box
frm.WordBox.value = words[rnd]
}

1st, Hi Coding forums! I'll get to the point, I'm a noob -.- I'm using greasemonkey for a certain website. Basically, I'm using gm to refresh the page after a certain time, I was however wondering, If I can set it to a random number between 2 specific times? The code I'm using atm is setTimeout(function() { document.location.reload(); } , 10000); I know I have to use math.random, well, I think I do. But I'm not sure how to do it between 2 certain times? So to summarise, I'm trying to refresh a page at any given random time between say 5-10 minutes. Any help is appreciated, thanks! I want a certain amount of image spots to show a certain set of images (specifically 8) in a random order every time the page is refreshed. I do not want the images to be repeated, however. The solution I came up with was to create an array and generate a number one to eight and then compare that number to the numbers previously in the array, and if it matched one that was previously generated, to generate a new number and then compare it. This continues until i have an array of the numbers 1-8 in a random order. Code: var imgs=new Array(8);
for(i in imgs)
{
function generate()
{
return Math.floor(1+Math.random()*8);
}
var rand=generate();
function compare(i)
{
for(var n=i-1; n>=0; n--)
{
if (n<0)
{
imgs[i]=rand;
}
else
{
if (rand==n)
{
rand=generate();
compare(i);
}
}
}
}
}
This does not strike me as the most efficient way to go about this. If someone has a better solution, that would help a great deal. I am working on a work project that requires a 5*5 table, that will generate random letters in each cell upon button click. I have most of the coding complete with the exception of the letter generation. I am currently generating numbers, I would even be fine with having a RandBetween(and listing the 26 letters of the alphabet) at this point. Any suggestions? Code: <script type="text/javascript">
var random1, random2, random3, random4, random5, random6, random7, random8, random9, random10, random11, random12, random13, random14, random15, random16, random17, random18, random19, random20, random21, random22, random23, random24, random25;
var randomArray = [0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0];
//generate the random characters
function CreateCellData() {
for (var i=0; i<randomArray.length; i++) {
randomArray[i] = Math.floor(Math.random()*99 + 1);
}
}
Hello, I need help creating a function in javascript that produces random numbers generated from a normal curve distribution with a mean and standard deviation that I can specify (and easily change). I would like only whole numbers and the ability to set reasonable maximum and minimums. Thanks, Adrian Sorry about the title, I didn't know what else to use to describe my problem. Basically, I'm generating a random word with a function; then I'm trying to pass this word down to another function. The problem is, when I pass the word, it changes each time (due to it being randomly generated originally). I'm only calling the function once (via button click), but I'm also calling the function in my code lower down to retrieve the returned variable; and the function seems to be running again and returning a new word from my array. Here's a snippet of my code: Code: function ranNum(){
var ranNum = Math.round(Math.random()*10);
var chosenWord = wordArray[ranNum];
return chosenWord;
}
function makeBoxes(x){
//remove children when new word is chosen
var hM = document.getElementById("hangMan");
while(hM.firstChild){
hM.removeChild(hM.firstChild);
}
var chosenWord = ranNum(x);
var wL = chosenWord.length;
//create box for length of letters in word
var i = 0;
for(i=0;i<wL;i++){
var cBoxes = document.createElement("div");
cBoxes.className = "letterBoxes";
cBoxes.innerHTML = chosenWord.charAt(i);
hangMan.appendChild(cBoxes);
}
return chosenWord;
}
function checkLetter(y){
var chosenWord = makeBoxes(y);
alert(chosenWord);
}
So I generate a word with one button; now I need to be able to work with said word in my checkLetter() function. The word changes however. Any help would be greatly received. I have a text file(quotes.txt) with 35+ quotations, separated by a single line break. Is it possible for a DIV to display a random quotation from quotes.txt each time the user visit my home page?
I'm stuck in my code where I need to have a particular quote or text steady in my site for every 30 minutes and changes only after 30 minutes. Right now I'm just randomizing the array of quotes using rand function. Can anybody please help me with having one steady for every 30 minutes. My intention is that everybody on the site at that moment should be seeing the same quote for 30 minutes. Visitors come from various countries. Code:
<script language="JavaScript">
var Quotation=new Array()
Quotation[0] = "Time is of the essence! Comb your hair.";
Quotation[1] = "Sanity is a golden apple with no shoelaces.";
Quotation[2] = "Repent! The end is coming, $9.95 at Amazon.";
Quotation[3] = "Honesty blurts where deception sneezes.";
Quotation[4] = "Pastry satisfies where art is unavailable.";
Quotation[5] = "Delete not, lest you, too, be deleted.";
Quotation[6] = "O! Youth! What a pain in the backside.";
Quotation[7] = "Wishes are like goldfish with propellors.";
Quotation[8] = "Love the river's \"beauty\", but live on a hill.";
Quotation[9] = "Invention is the mother of too many useless toys.";
var Q = Quotation.length;
var whichQuotation=Math.round(Math.random()*(Q-1));
function showQuotation(){document.write(Quotation[whichQuotation]);}
showQuotation();
</script>
Hi, I have been here before and was responded to quickly with professional results, and you guys have managed to bring me back! Anyway, I am horrible at coding, and I need to know how to write this, basically when the page loads a random number is generated <script type="text/javascript"> window.onload=function() { var random = Math.rand() * (6 + 1); Then later in the page if (random = 1) { document.write("1") //I'm not sure if thats the code to show simple text, but I'm pretty sure it is, correct me if I'm wrong } if (random = 2) { document.write("2") } if (random = 3) { document.write("3") } and so on so forth. I will be changing the numbers in the script to my accord and use of the script, so please use the //notes to mark where and what things is, with a brief explanation, so I don't have to unscramble the code to find out what it is. Thanks fellow nerds! So I found this script and i give all props to the author but can anyone help me to add text to the random images. Also i need a button that will generate the random images/text not when you refresh the page but when your press the button and to not display any image/text till the button is pressed? Thanks in advance. [CODE] <script language="Javascript"> var currentdate = 0 var core = 0 function StringArray (n) { this.length = n; for (var i =1; i <= n; i++) { this[i] = ' ' } } image = new StringArray(10) image[0] = 'images' image[1] = 'images' image[2] = 'images' image[3] = 'images' image[4] = 'images' image[5] = 'images' image[6] = 'images' image[7] = 'images' image[8] = 'images' image[9] = 'images' var ran = 60/image.length function ranimage() { currentdate = new Date() core = currentdate.getSeconds() core = Math.floor(core/ran) return(image[core]) } document.write("<img src='" +ranimage()+ "'>") </script> <form> <p><input type="button" name="B1" value="Switch It Up" onclick="ranimage()"></p> </form> [CODE] I'm using the script below in a custom HTML to generate a random line of text (not with the text shown here). This works fine BUT; I want it to go randomly through the WHOLE list without repeating lines that already have been printed. As it is now, a line of text might be printed several times in a row, which is a little annoying. I'm using a refresh button for generating a new line of text. Alternatively, How can I just make it display in the order shown and just re-arrange the content so it seems random to the user? Random would the best though... Any ideas?? : ) Code: <script language="JavaScript"> <!-- var r_text = new Array (); r_text[0] = "All the leaves are brown"; r_text[1] = "And the sky is grey"; r_text[2] = "I've been for a walk"; r_text[3] = "On a winter's day"; r_text[4] = "I'd be safe and warm"; r_text[5] = "If I was in L.A."; r_text[6] = "California dreaming, On such a winter's day"; var i = Math.floor(7*Math.random()) document.write(r_text[i]); //--> </script> Hey all. I'm looking for a way to have a single, random line fetched from multiple text files, and then have that combination output somewhere, whether just to some field or another text file. For example: Text file A - I like I hate I love I despise I cherish Text file B - apples bananas oranges grapes grapefruit pineapple cherries Text file C - some of the time. most of the time. a lot of the time. pretty much never. So it would go in, get a line from each, and display something like: I love - grapefruit - most of the time. I cherish - pineapple - some of the time. etc. etc. I know it's a weird-sounding example, but you get the point. The line choices don't have to be separated by hyphens, but they preferably would be separated by something, like a comma, semi-colon, slash, whatever. I know this is pretty much a web coding forum, so that would be fine if I had to host it on my server or open it with a browser. But it would be optimal if this could be made into a standalone executable. I'm basically looking for something like Random Line Picker, just with the added functionality I mentioned. I'd be willing to make a little donation to someone if coding this would be a little difficult. Thanks! http://www.akirathedon.com/wp-conten...urama/TEST.php This code works almost perfectly for my needs bar one issue. As i have included paragraphs in the content, the ellipses is forced below the paragraph, when ideally it would sit directly next to where the text was trimmed. Can anyone think of a way I can do this with javascript or css? I tried making the paragraph an inline block and setting the ellipsis to inline but I lost my paragraph line breaks. Thanks you. I've looked for a solution to this issue, but it seems like a little different scenario than other situations. I made a system for generating friend requests on Facebook. I have a grid that is 6 x 3, for a total of 18 cells. Each cell has a picture in it, and the picture is linked to the Facebook friend request page. My problem is that since each cell is populated at random from the array, I'm getting lots of repeats. For example, some picutures are in 5 cells, and some are in none. I'm trying to figure out how to make it so that once a picture is used once in the grid, it does not get used again in the same grid. I still want every cell filled at random on each page load, I just want to prevent the repeating. Here's my current code: Code: <script type="text/javascript">

Any suggestions? Thank you! Hi - in editing a website...this javascript html is really getting on my nerves - can somebody please tell me why i keep getting the error message expected ")" when i try this code: (which ive fiddled around with bloody loads to try and resolve!) <SCRIPT LANGUAGE=JAVASCRIPT > var r_text = new Array (); r_text[0] = Text 0; r_text[1] = Text 1; r_text[2] = Text 2; var i = Math.floor(3*Math.random()); { document.write("<marquee style="font-family: 'Georgia'; color: #FFFF00; font-size: 13pt; mso-fareast-font-family: 'Arial'" ><scrollamount="15"><b>" + r_text[i] + "</b></scrollamount></marquee>"); } it seems fine to me and is getting me really frustrated now any help greatly appreciated, do whatever you like to the coding if itll work! thankyou very much, joe. Hello, I have this idea, but I wouldn't want to reinvent the wheel if it's already been done. I want to generate perspective grid on canvas depending on browser window size, something like this, but without textures: http://www.123rf.com/photo_2651286_a...rspective.html Do someone of you guys know if some similar script already exists? Or at least some tips on how not to end up writing a 1000 lines script (At this point I would just drop the idea)? All thoughts appreciated. P.S. even an obscure algorithm would probably suffice, 'cause the main problem I'm struggling with is diminishing size perspective calculations Ok, just to be honest this is for my assignment from my University, I have completed the whole code myself I just can't seem to get just one little thing. Code: function GenerateTables(){
var start = document.tables.start.value;
var end = document.tables.end.value;
var size = document.tables.size.value;
for (start; start <= end; start++) {
document.write("<table width='100' align='center'>")
document.write("<caption><b>Table of </b>" + start + "</caption><br>")
document.write("</table><br>")
for (var i = 1; i <= size; i++) {
document.write("<table border=1 align='center'>")
document.write("<tr height=40 align='center'>")
document.write("<td width=40 align='center'>" + start + "</td>")
document.write("<td width=40 align='center'> * </td>")
document.write("<td width=40 align='center'>" + i + "</td>")
document.write("<td width=40 align='center'> = </td>")
document.write("<td width=40 align='center'>" + start * i + "</td>")
document.write("</tr>")
document.write("</table>")
}
}
}
The function generates multiplication tables depending on the input user provides using this interface (given below). And it generates them like this (given below). Now what I want is to generate those tables sideways not downwards. Not all the tables, but it should complete one table downwards, then start the new table on its side. I can't seem to figure out anything that would make that happen, and ideas would be appreciated, thanks. Regards, Papichoolo. I found this code in another thread... basically, I need to be able to display a certain image based on the page's title... for instance if the title is: Lotus 7, I need image lotus.jpg to display in an element on the page, however, if the title is Bodhi 9, I need image bodhi.jpg to display in the same element. Can someone help me implement this code? Code: var imgs = new Array(); imgs[0] = new Array(); imgs[0][0] = "Research"; imgs[0][1] = "bluetabs_01"; imgs[0][2] = "greentabs_01.gif"; imgs[1] = new Array(); imgs[1][0] = "Information" imgs[1][1] = "bluetabs_02"; imgs[1][2] = "greentabs_02.gif"; Code: var title = document.title;
for (var i=0;i<imgs.length;i++){
if (title.indexOf(imgs[i][0])!=-1){
document.images[imgs[i][1]].src = imgs[i][2];
break;
}
}
I'm new to programming, Here's my problem: I'm using a for loop to generate a list of hyperlinks for(i = 100; i < 200; i++) { var str = "link"; document.write(str.link('http://someWebsite.com/' + i +'.html')); document.write("<br />"); } so the list that is generated looks like... link link link ---------and so on until the loop is finished. My question: is it possible for each links text to be dependent on the pages title? for example instead of the the text "link", the program would follow the URL and know in the pages header was the title "Bob's website" or whatever the pages title was and would generate the list. Example: bobs website daves website rons website susies website betsys website ______________________________ Any help to differentiate the links text based on following the URL would be helpful Thank you! Hi all, I have been checking out this web audio api app Beat Petite The thing that really interests me about it is that as the user alters the interface settings the URL changes, and all the settings can be recalled just by saving the URL (so if you make a cool drum beat you can share it with your friends by giving them the URL). I would love to be able to implement this feature on my own site but I have no idea where to start! Can anyone shed any light on how this can be done? I am not even sure if this is JavaScript that is controlling this or some other technology. Any ideas would be much appreciated. Thanks, Hulk |
