View 2 Replies View RelatedI 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.
So to start out, this is my first post on CodingForums! :) I've only recently started learning web development so I figured it would be a good idea to get involved with some active forums.
I am trying to open a random page in a frame, but I am trying to call the Javascript to do so in another frame. I currently have an html page with a frameset which has two frames. One of the frames is a toolbar that sits at the top of the page and it has an image that acts as button. When the user clicks on this image, the bottom frame generates a random page from an array of links I have hardcoded into the Javascript. The bottom frame is just set to google.com as a default because I couldn't really think of anything to put in an html file there.
The problem I'm having is when I click on the image to open a random page in the bottom frame, nothing happens. The code for all the files are below. code...
I got this code and it generates random numbers but with repeating code...

What I am struggling with is the logic to say if minyears is more than 1 (string in option needs to say years), then add in every year between min and max as additional options. My brain has been melting with this for a few days now
I would like to be able to generate a table from which I can easily edit the contents of a mySQL database (similar to phpMyAdmin.) In that table I would like to have a button that will open a pop-up, allowing me to edit - and maintain formatting such as apostrophes and line breaks - a long description field. That popup will then populate a hidden input field on its parent with the modified description.
I've got the pop-up opening and its fields are populated using php's GET function (see line 11). The special characters, particularly carriage returns, are messing me up; I can remove them using php's str_replace, but I want to retain them for formatting.
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>

<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>

View 7 Replies View Relatedi have many inputs like:
<input type="hidden" name="combi[<?php echo $sysCompData['combi_id'];?>][desc_features]" value="<?php echo $sysCompData['desc_features'];?>">
I do not know the value of both PHP-Values, they come from a database. I have tried now some hours to grab the values of this array, because i have to compare them to other values in similar inputs. But I simply do not know how? For a simple test i simply want to change the value of the chosen fields. I tried (nearly) everything from something like $("input[name='combi']").val('test'); to $("input[name='combi'//[//]//[//]]").val('test'); . In PHP I have absolutely no problem, i go simply through the arrays with:
<?php foreach ($combi as $i => $combiData): ?>

At the moment it allows for 2 images to be magnified, but I intend displaying over 50 product images whose details are taken from a database. how to change the red parts of the script to read the changing information.

View 1 Replies View RelatedI would like to have a jsp page with a form consisting of several inputs and selects. When page loads for the first time, there is only one select (with values taken from database), but after clicking on link "add", the subsequent selects are added (using JavaScript and DOM). It seems to be pretty easy task, but I'm not sure how to populate the newly created select with data.

how to call the values at random in the arrays: article, noun, verb, preposition ?
I have an array containing 100 different values. How would I randomly pick 25 of them for display? For now I do: for (var i=0; i<markers.length && i<25; i++) {
html += markers[i].name + '<br />';
}
Which of course returns 25 values but always in the same order which is not what I want. PS. My array could also contain only 20 values, in which case I would like the function to display the 20 values randomly sorted.
I want to build something like a foldable tree using Jquery. But the problem is I am getting the values from a Database.My database structure is
