Random Number Within A Range Not Working With Form Values?

Sep 28, 2009

This statement is to produce a random integer within a specified range. I get the desired result when passing the values within a function like this:

Code:

<html>
<script type="text/javascript">
function get_randomRange(low,high){

[code]...

the results form the second example look like the number are possibly being multiplied somewhere? why does the first example work and the second not?

Generate Random Number Within A Range?

Jun 30, 2009

I am trying to generate random number within a range. My code at the moment is

Code:

var uppermax = 100; var uppermin = 10; var upperdiff = uppermax - uppermin; var lowermax = 10; var lowermin = 0; var lowerdiff = lowermax - lowermin; var rand = Math.floor(upperdiff + 1) * Math.random() + uppermin; alert(rand);

I know math.floor is supposed to round down to the nearest integer, but the generator is still coming back with a float.

Adding Random Number To HTML Form?

May 29, 2009

I have a pretty basic HTML form, it doesn't go to a database or anything, it just gets emailed directly to the owner of the website with their customer query.However, the owner has now asked that each query be assigned a random reference number of no more than 16 digits which must also be visible to the customer.I presume this will be relatively easy but I'm a complete beginner with Javascript which I assumed would be necessary for generating the number. I've sort of figured out how to generate the number but I can't figure out how to get that number into a read-only field on the form so that it will be both visible to the client and sent with the rest of the data on the form to the owner.I've had a number of attempts but this is what I'm trying at the moment:

Code:
<html>
<head>

Form In Html That Contains Table Row - Missing Something When Validating Random Number

Oct 5, 2011

I wanted to throw a quick and easy .js function into my comments section to ward off some spamming bots. I have a form in html that contains this table row.

The function I am calling sits in an external .js file. The file itself has a handful of functions but I will post the important bits below.

The form has other fields that validate just fine.

JQuery :: Validate A Form Only If A Value Is A Number Between Two Values?

Mar 8, 2010

I'd like to validate a form only if a value is a number between two values.For example value foo must be more than 24 and less than 29. I know this:

Code :

rules: {
foo: { required:true, number:true, equal:25}
}

But how can I test that : 24 < foo < 29 ?

JQuery :: Datepicker With Range - Send Values To Php Script And Display The Result?

Jun 6, 2011

I have a date picker with a textbox input for 'from' and 'to' the page loads with default values which display in the textboxes.What I want to do is: when the page loads, these values are sent to my SQL server, the server checks for entries that are within the range, then reports back on the page the results.Subsequent changes to either from or to dates should result in a similar call to the server for validation. no submit button, just change date = changed output.I figure the best way to do this is with AJAX. So I have a date picker, but how do I send the results to a PHP file to do what it will with them? And once the php file is done with them, how do I put the results back on my HTML page?Now for some code:

In <head>
<!------------------------------------->
<!-- DATEPICKER CONFIGURATION -->[code]....

So that's all the code that makes my Range Select date picker. My question is very similar to http:[url]....with-ajax-and-jquery-datepicker except that I probably lack even more knowledge than that OP - I need a step-by-step baby solution to how this all works.Where in my code does the $.ajax() function go? How do I handle two dates, not just one? How do I get the output on screen? Finally, in my PHP script, would this at least provide me output?

<?php
$from_date = $_GET['from_date'];
$to_date = = $_GET['to_date'];[code]...

Random Number But Only Once?

Aug 31, 2011

I'm trying to apply something in my forums, where a member could post something let's say:"Hi, I am number 1, 6"And what would happen is that, a number from 1 to 6 would be the content, for example, it would be:"Hi, I am number 3"But if you refresh the page, it would still be the same number. Like it won't be randomized again.So how do I make a javascript/html code that would make a one time number randomizer.

Generating Random Number

Feb 28, 2006

In the forum, it usually talked about generating a number between 1 or 0 to that certain value using something like Math.round(Math.random() * 200); or Math.floor(Math.random() * 200);

But what do you do if you want to generate a number between 201 and 400.

Regenerating A Random Number?

Apr 23, 2009

I set myself the task of creating a button which, when pressed, switches the background color randomly. It seems to work well enough but the random number it works from only generates once at page load.As a workaround, I added a second 'Reset Page' button, but I really want just one button that switches the page color every time you prod it. Any ideas how to reset the random number to achieve this?Here's the code.

Random Number Generation Different For IEs?

May 10, 2009

All the numbers should match. It's not working right in any version of IE I test it in (6, 7 and 8). I'm also using jQuery, fyi.When you click the button to stop the numbers, I'm setting a variable named winner to a number (3, 4 or 5). Right now, I have it set to 5. This number determines how many of the slots match:[code]I'm then generating a random number (0-8) to base all the other numbers off of . Three numbers will always match, so I'm setting two more variables to match that random number.[code]Then I do some conditionals to check the value of winner. If it's 4, I set the 4th number to random number, then generate a random number for the 5th spot while it doesn't equal randomnum. I do something similar if winner is set to 5.[code]The goto trigger sends the scroll to the specified index according to slotnum(1-5).I'm waiting to hear back from the plugin developer to see if it's something to do with that.However, I just want to make sure my logic in generating those numbers is sound. It works perfectly in FF, Opera and Chrome but (surprise!) not in any of the IEs (tested in 6, 7 and 8).

Button Prints Out Random Number

Sep 23, 2011

I am trying to make it so that when you press a button it prints out a random number. This is what I currently have:

Code:
<script type="text/javascript">
function randomnumber(randomForm){
var x=Math.floor(Math.random()*11);
document.write(x);
}
</script>
<FORM>
<INPUT type="button" value="Print Number" name="button1" onClick="randomnumber(this.form)">
</FORM>

When I click on the button it just clears all the text from the page and clears the bgcolor. A random number then appears at the top left corner. I am trying to make it so that when I press the button it prints out a random number just above or below the button. Is this possible? if so how do you set it up?

Create Random Number Between 1 - 50 With Decimals?

May 24, 2011

How would I go about creating a random number between 1-50 that COULD include whole numbers, decimals to the tenth, hundredth and the thousandth place?
Ex) 2.145, 3, 5.8, 41.002, 10.12, 7, 18.023, 33.2

Also, if the only way to do it is to put trailing zeros to the thousandth place that's fine as well
Ex) 2.145, 3.00, 5.800, 41.002, 10.120, 7.00, 18.023, 33.200
