I have a form wich has a add/remove row button, this so the visitor can select multiple sets of data. All is fine and is being submitted via PHP.
Only problem is from number 10 and up, i am getting strange random numbers in the new rows that are added in their name. Like 1111 (instead of 11), 122222 (instead of 12). And because of this, every row from 10 and up won't be send through php, giving this random effect.
I'm a starter in using jQuery and I decided to work my way through the 'Learning JQuery' book from packt.Somewhere in Chapter 5 they use the clone() function with the false attribute. The JQuery version used in the book is 1.1.3a. With the clone(false) method the writer can clone only the matched element and not the descendants. And that works in 1.1.3a.I know that this is no longer the case in JQuery 1.4. Boolean is only for Event Handlers.But what is the new equivalent of this method? In other words. How can I clone an element with only the matched element and not it's descendants?
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.
<script language="JavaScript"> // Unique Random Numbers Picker // By Premshree Pillai
var numArr = new Array("0","1","2","3","4","5","6","7","8","9"); // Add elements here var pickArr = new Array(); // The array that will be formed var count=0; var doFlag=false; var iterations=0;
This script is a slightly modified version of "Unique Random Numbers". In this script it becomes easier to implement more than one instances of "Picking Unique Random Numbers".
This JavaScript picks up a number of unique random elements from an array.
For example; if you have an array myArray consisting of 10 elements and want to pick 5 unique random elements. Suppose initially myArray[3] is picked randomly, then myArray[3] should not be picked again.

My Name is Tom I am from the UK and I am (for my own entertainment and learning) creating a dvd indexing web application to sort and catagorize my dad's dvd collection. On the homepage for this website I have dynamically (using JS) appended 3 image elements which contain the images of dvd box art at "x by 225" pixel dimensions i.e. when I resize the dvd box art they all have to be 225 pixels in height and constrain to the necessary width in contrast to the height. Now that the images are working, I now want them to be randomized so 3 unique box art images are displayed everytime the page is refreshed. So far my script is:
Code:
// Image Rotation Javascript function imageRotation() { // Preload images
[Code].....
Problem with this is that sometimes I get results from the random number generation that are non-unique i.e. sometimes random_number1, random_number2 and random_number3 yield: 3,3 and 11 etc. I need to make it so that you never get such clashes or it will show 2 or more identical images on the homepage. How can I change the random number generators to achieve this?
how to plug the imgObj into the image elements as to use the preloaded images instead (at the moment their just hard coded.)
I would like to create a Blackjack style game for one of my high school programming classes. I can generate 3 different random numbers and use these random numbers to display an image with that number on it.
How do I add the 3 separately generated numbers together to show the total??
Here is my code so far. Specifically I would like to add the myNumber1(), myNumber2() and myNumber3() results together.

I have a quick question with multiple array and random numbers. If i generate my random numbers in one array, how would i take a selection of those numbers and put them in another array?
Ex: array 1: 25, 34, 38, 40, 22, 49
Want to move numbers between 30 and 50 to another array.
array 2: 34, 38, 40, 49
Is it as simple as for loops and if statements setting the conditions? do i use a sorting method? (selection? bubble?)
I have a table with a couple random numbers, and i want to click a button that will dynamically regenerate the numbers each time the button is clicked without re-generating the entire table., im using DOM and innerhtml for these random numbers. heres the javascript and html code. so far, it just generates the random numbers when the page loads.[code]...
I am working on a problem that wants me to use a for loop to give an array a random number for each of it's elements (total of 10) and then using a second loop to add them up and display the result.

I am trying to create a javascript code in which I prompt the user for a number (an integer from 0 to 100) to search for, then search a function with the number they entered and then display whether the number was found, and if found, a location where it can be found within the list.
I've got my code, and the task is to generate two random numbers, the user then inputs an answer for them added together, then the program checks the answer and displays either "correct" or "wrong". Here's some of my code:
Code: <HTML> <TITLE>Assessment Task 3 : Rohan Gardiner</TITLE> <HEAD> <SCRIPT LANGUAGE ="JavaScript"> function maths(){ var response; var answer; answer = document.questions.answer.value; if (answer==document.adding){ response = "correct"; } else { response = "wrong"; } document.questions.result.value = response ; } function randoms() { rndNum = Math.random(); Num = rndNum*20; Num1=rndNum*10 document.write(Math.round(Num)+"+"+ Math.round(Num1)); } function adding() { document.write(Math.round(Num) + Math.round(Num1)); } </SCRIPT></HEAD><BODY> <h1 align="center">Rohan Gardiner Assessment Task 3</h1> <FORM NAME = "questions"> <SCRIPT Language=JavaScript> randoms(); </script> = <INPUT TYPE = "textbox" NAME = "answer" > <BR> <INPUT NAME = "dobutton" TYPE = "button" Value = "check" onClick= "maths()"> <INPUT TYPE = "textbox" NAME = "result" > </BODY></HTML>
I'm trying to generate random numbers 0-8 to use to access array indices.[code]Every once in a while, I'm getting a -1 in my console log. I read on a site that this line:[code]will generate a number between 0 and 10 (so 1-9).How is -1 being generated?
I have a page which contains an <ul> list with 5 items. Each of those items has a data-weight attribute which corresponds to its importance in the list. I have to make only one random list item appear and use the weight to make sure that the most important one shows up more often than the least important item.
I'm trying to use Javascript to have an array of images that load randomly AND work in a slideshow manner so change every 3 seconds (in a logical order). The code I have below presents a random image but how do I get them to continue from the random image and change to the next every 3 seconds?
