Random Numbers	View Content

Hi,
I have this bit of java code that puts a random/unique number in a field on my web page:
<html>
<head>
</head>
<body>
<form>
<input type="text" name="MyField" />
</form>

<script langueage="javascript" type="text/javascript">
var d = new Date();
var tm = d.getTime();

document.getElementsByName('MyField')[0].value=tm;
</script>

</body>
</html>

My problem is that I want to limit the number to just 6 digits. Is this possible?

Any help would be much appreciated

Thank you

Generating A Random Between 2 Numbers [help!]

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 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.

myNumber2();
myNumber3();

myNumber1D();
myNumber2D();
myNumber3D();

Clone Element, After Row 10 Random Numbers

Similar Tutorials

View Content

Hello all,

I hope someone can help me with this.

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 can't seem to find why this is happening.

Hopefully someone can help me out in this.

The full form can be viewed

var clone;

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.

var random = Math.floor(Math.random()*40 + 1) //sets variables for random numbers to generate
var random2 = Math.floor(Math.random()*40 + 1)
var random3 = Math.floor(Math.random()*40 + 1)
var random4 = Math.floor(Math.random()*40 + 1)
var random5 = Math.floor(Math.random()*40 + 1)
var random6 = Math.floor(Math.random()*40 + 1)

//create table
function makeTable(lotto)

document.getElementById("tableSpan").innerHTML = '<table border="1" id="lotto">';
var caption=document.getElementById('lotto').createCaption();

caption.innerHTML="JavaScript Random Numbers";

var x=document.getElementById('lotto').insertRow(0);
var cell1=x.insertCell(0);
var cell2=x.insertCell(1);
var cell3=x.insertCell(2);
var cell4=x.insertCell(3);
var cell5=x.insertCell(4);

Hello! 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. Can you please tell me what is wrong?

How To Prevent Repeating In A Random (math.random) Array?

Similar Tutorials

View Content

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:

I want to see what the function would look like to be able to convert into different currencies by using arrays. I know that this would be a useless way to do it as they are updated every day, but it's for personal education purposes.

(Note: The website contained a textbox in which to enter the amount in pounds, a drop-down box allowing the user to select currency, a button to click to convert, and another text box showing amount of money after converting.)

Any help is greatly appreciated.

Sequence Of Numbers

This textbook is complete garbage, there is nothing in this thing about this topic at all. Here is the question I am trying to do: "Suppose you have a sequence of numbers
Where every number is the previous number plus 3
1, 4, 7, 10, 13, 16, 19, 22
Write a program to output the first 10 number s of the sequence. You must calculate the numbers, you cannot just hard-code them into an array."

Its a question on a test study guide.

Heres what I got so far: Code:

<html>
<head>
<script type="text/javascript">
VarX = 1
i = 3
VarY = VarX + i
count++
do
varY 
while count < 10
</script>
</head>

What I want to do is add more word lists. This of course is easy in principle - I can just continue the lists like:

form.title9.value = "";
form.title10.value = "";
form.title11.value = "";

- and so on. The problem is that, in the "sentence patterns", I cannot use numbers with two digits to refer to the word lists. Then it thinks I mean 1+0 and 1+1 instead of 10 and 11. How can I allow this? I have heard about using regular expressions to "capture the number by its word boundary" - is this a good solution? If yes, can someone please explain to me how to do it? (I have tried special characters like @,#,$ and more as well as Russian and Greek letters. This makes the script unable to generate poems.)

Thank you.

Convert the string values which are concatenated by + (e.g. "2" + "5" = 25) into numbers (e.g. 2+5 = 7) by using the Number() method, or another way is to multiply the value by 1.

But you are using string values
if (chr == '1') {
quite unnecessarily.
Remove the quote marks to make them into numbers.
"1" is a string value. 1 is a number

Obviously chr = pattern.charAt(ichr); only captures a single numeric chararcter.
You can extract two-digit numbers from a string just by removing all non-digits
var x = str.replace(/[^0-9]/g,""); // strip all characters but digits
That of course assumes that there is only one number in the string.

Js Adding Numbers

Hi,

Want to add numbers using JS. Have 4 text boxes for user entry. Want either a label (preferred) or fifth text box to automatically sum those entries. Did following but not working. Any suggestions?

<script language="javascript">
var addRange = function()
{
var NoHrsRangeComp = document.getElementById("NoHrsRangeComp");
var NoHrsRangeCred = document.getElementById("NoHrsRangeCred");
var NoHrsRangeOT = document.getElementById("NoHrsRangeOT");
var NoHrsRangeRC = document.getElementById("NoHrsRangeRC");
var RangeSum = document.getElementById("RangeSum");
var sum = 0;

if (isNaN(parseFloat(NoHrsRangeComp.value))){
NoHrsRangeComp.value = ""; }
if (isNaN(parseFloat(NoHrsRangeCred.value))){
NoHrsRangeCred.value = ""; }
if (isNaN(parseFloat(NoHrsRangeOT.value))){
NoHrsRangeOT.value = ""; }
if (isNaN(parseFloat(NoHrsRangeRC.value))){
NoHrsRangeRC.value = ""; }

sum = parseFloat(NoHrsRangeComp.value) + parseFloat(NoHrsRangeCred.value) + parseFloat(NoHrsRangeOT.value)
+ parseFloat(NoHrsRangeRC.value);
RangeSum.innerHTML = sum;
}
</script>

Input as follows:

<input style="width: 50px" type="text" name="NoHrsRangeComp" id="NoHrsRangeComp" onblur="addRange();"/>

<input style="width: 50px" type="text" name="NoHrsRangeCred" id="NoHrsRangeCred" onblur="addRange();"/>

<input style="width: 50px" type="text" name="NoHrsRangeOT" id="NoHrsRangeOT" onblur="addRange();"/>

<input style="width: 50px" type="text" name="NoHrsRangeRC" id="NoHrsRangeRC" onblur="addRange();"/>

<input style="width: 50px" type="text" name="RangeSum" id="RangeSum" onblur="addRange();"/>

For above entry prefer - label makes it look more like usual addition and does not confuse users to want to make entry.

<label id="RangeSum" onblur="addRange();" style="border-bottom:medium"></label>
