JavaScript - Show Max And Min Values In A Array List
Hi, I'm trying to find out the min and max values of randomly generated values in a array list. Its a checkout system that randomly add a customer to a queue and does the same to remove a customer depending on a randomly generated number. Ive managed to figure out the mean of the queue but can only display the total values added to the list rather than display when the queue was at it biggest value. If anyone can point me in the right direction it would be greatly appreciated.

Hi. Now I know this is a fairly easy task, but I need to show the random div from a selection of 10 which all have the same class. I am not able to do this using unique IDs as the divs will be created by the end user as a repeating region from Adobe contribute. So I'll have a list looking something like the following but I only want one to show. Any ideas? Code: <div class="mydiv">Line Number One</div> <div class="mydiv">Line Number Two</div> <div class="mydiv">Line Number Three</div> <div class="mydiv">Line Number Four</div> <div class="mydiv">Line Number Five</div> <div class="mydiv">Line Number Six</div> <div class="mydiv">Line Number Seven</div> <div class="mydiv">Line Number Eight</div> <div class="mydiv">Line Number Nine</div> <div class="mydiv">Line Number Ten</div> It adds fine when any number but 12.3 is used if 12.3 is used however it gives 54.099999999999994 var liu = [10.6,11.2,9.4,12.3,10.1]; var calculateTotal= function(raceTimes){ var totalTime; var raceTime = raceTimes[0]; var i =0; for (i = 0; i< 4; i++){ raceTime = raceTime+raceTimes[i]; totalTime = raceTime; } return totalTime; }; var liuTotal = calculateTotal(liu); console.log(liuTotal); Hi, I have a dynamically generated list of which contain div's with a class of product. I want to only display 6 random products out of the whole list on page load and hide the rest. I am quite new to javascript so some help would be much appreciated. Thanks hi, the following function shows a list of Counties populates by a PHP page: Code: $.getJSON('http://www.mypubspace.com/dashtest/countyjson.php', function(data){
var myhtml = '<ul>';
for(i=0; i<data.length; i++) {
myhtml += '<li>' + data[i].County + '</li>';
}
myhtml += '</ul>';
$("#countyshow").html(myhtml);
});
I would like to now, when a user clicks on a County, they are shown a list of pubs based on that County (so, I'll create a new PHP page WHERE County = 'County' or something?!) at the moment, when a user clicks on a County this function is passed: Code: function gopublist(event)
{
var stackLayout = document.getElementById('stackLayout').object; // Replace with id of StackLayout
stackLayout.setCurrentView('view4');
}
So, passing a value through so I can modify the SQL in the PHP page to filter the counties?! Please help? Hi, I doing my project in Netbeans, and I have this .java page, that sets and gets a html form where there are textboxes and drop down lists, as far as I know, although getElementById() is a javascript code, it can be used in my .java page, but I do not know how to implement it. What I'm supposed to do is to get the values from the drop down list and save them to a database that I've already have. Code: HtmlPage page = null; page.getElementById(id); but because I do not know what should the id be since the .java page is not a jsp page and the drop down list values cannot be retrieved directly. Need help here, thanks. hi, I would like to show a list of pubs in a town that the user has selected from the drop down list http://www.mypubspace.com/dashtest/order.html it is all there working but in a different way If you type Brighton into the Town search, it shows a list of pubs in that town, GREAT! If you click the 'show towns list' link, a drop down appears, (this is where my problem is) When you click the town, I would like to get the list of pubs in that town basically get rid of the form where you type in the box and click the button here is my code HTML and Javascript Code: <html>

Hi there. This is my first thread. I'm completely new to javascript. I want to use dreamweaver with javascript to do a litter project in which I want to move value "Saleman" from drop-menu 1 and value "Billy" from drop-down 2 to a list box. The result should be as follows: dropdown 1 Manager Salesman (to be selected) Cleaner dropdown 2 Billy (to be selected) Susan Ivan --- [Add button] Listbox Salesman - Billy Thank you for your help. Cheers Raymond Hi Everyone! I would genuinely appreciate some help on this one. I'm trying to combine a chained drop down list with the ability for the last selection to show/hide a div. I've researched and found ways to do both individually, but I'm hitting the wall when it comes to combining the javascript. This is how I'd like it to work: -- User selects from DropDown List 1. -- DropDown List 2 options appear based on the selection in 1. -- User selects from DropDown List 2, -- Appropriate div is shown. Here's the Javascript I'm using to show/hide a div: Code: function showDiv(divID)
{
var div = document.getElementById(divID);
div.style.display = ""; //display div
}
function hideDiv(divID)
{
var div = document.getElementById(divID);
div.style.display = "none"; // hide
}
function hideAllDivs()
{
//Loop through the seclect menu values and hide all
var courseSelect = document.getElementById("courseSelect");
for (var i=0; i<=courseSelect.options.length -1; i++)
{
hideDiv(courseSelect.options[i].value);
}
}
function toggle(showID){
hideAllDivs(); // Hide all
showDiv(showID); // Show the one we asked for
}
Here's the Javascript for the chained drop down lists: Code: <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script type="text/javascript" defer>
function cascadeSelect(parent, child){
var childOptions = child.find('option:not(.static)');
child.data('options',childOptions);
parent.change(function(){
childOptions.remove();
child
.append(child.data('options').filter('.sub_' + this.value))
.change();
})
childOptions.not('.static, .sub_' + parent.val()).remove();
}
$(function(){
cascadeForm = $('.cascadeTest');
deptartmentSelect = cascadeForm.find('.deptartmentSelect');
courseSelect = cascadeForm.find('.courseSelect');
cascadeSelect(deptartmentSelect, courseSelect);
});
And lastly, my HTML (simplified) Code: <form action="#" class="cascadeTest">
<table>
<tr>
<th>Organization:</th>
<td><select name="deptartmentSelect" class="deptartmentSelect">
<option value="0">Select a Department</option>
<option value="1">Dept A</option>
<option value="2">Dept B</option>
<option value="3">Dept C</option>
</select></td>
</tr>
<tr>
<th>Territory:</th>
<td><select name="courseSelect" class="courseSelect" onChange="toggle(this.options[this.options.selectedIndex].value)">
<option value="0" class="static">- Courses -</option>
<option value="A1" class="sub_1">Course A1</option>
<option value="B1" class="sub_2">Course B1</option>
<option value="C1" class="sub_3">Course C1</option>
</select></td>
</tr>
</table>
</form>
<div id="A1" style="display:none;">I am Course A1</div>
<div id="B1" style="display:none;">I am Course B1</div>
<div id="C1" style="display:none;">I am Course C1</div>
Thanks again in advance! I tried implementing a cleaner approach to a web form I had created, but it doesn't seem to be passing the values to the server properly. What gives? This form on the left and right work perfectly, but they have two ridiculously long drop down lists, which would be the "ProgramOfInterest" fields (please use the following values preselected in this form) http://www.nationalcollegesearch.org..._pingpost.html On this form, I tried creating a triple drop down list setup to clean up the older, long lists in this example, but it doesn't pass the values properly. It also seems to not duplicate the new drop down triple drop lists properly as in the original form. You can change the values in the drop downs in the forms to see what I mean. Also just pick Bachelor's > B_Business > Business Administration in the triple drop downs for an example since I don't know how to preselect those values. http://nationalcollegesearch.org/Integrate/PleaseHelpMeWithMyCode/integrate_pingpost_experiment.html Please let me know if there is anything I can do to pass the correct values to the server. Thanks! P.S. Please note that I have disabled the form on the right and intentionally left the action empty. This is the triple drop down script I am using: Code: <script type="text/javascript">

http://www.mypubspace.com/dashtest/newjson.html hello I am having a problem to add numbers store in an array. arrayValues[0][0] = 1; arrayValues[0][1] = 2; var col = 0; var sum; for ( var row = 0; row < index; i++ ) sum += arrayValues[col][row]; my result is ==> 12 it is defining my sum variable as string. even I try do do this var sum = 0; to define sum as numeric variable. my result was ==>012. Any idea, this is my first javaScritp code. Thanks. Hi Guys, How do I sum the values of an array and output the result using document.write? Say my array is var number=new Array(1.234,56.43,1.02); THANKS Thought this wud work? Code: <script type="text/javascript"> var x = [1, 2, 3, 4, 5, 6, 7, 8, 9]; document.write(sum(x)); </script> I'm having problems with selecting values from array. I have a dropdown box where you choose what fruit you want to buy. When selected the array should assign 2 values to that fruit. I don't know how to do that. Here's what I have.. I added comments. Javascript part: Code: <script type="text/javascript">
function Fruits() {
var selectfruit = newArray( //assigning values to fruit selected from dropdown box
newArray("Banana", 1, 1),
newArray("Apple", 1.2, 0.5),
newArray("Mango", 1.1, 0.9),
newArray("Orange", 0.1, 9.99));
var howmanyfruits = Number(document.getElementById("howmanyfruits").value); // how many fruits are you buying
var totalfruitsowned = Number(document.getElementById("totalfruitowned").value); // How many fruits do you already have
/* cash and coupons needed to buy fruits.
cash is cpst for 1 fruit.
coupons is cost for 1 fruit
cash_all is cost for all fruits you're buying
coupons_all is cost for all fruits you're buying
each fruits requires cash AND coupons to be bought. Cash and coupons are tied to the first values in Array.
Eg. If you choose Apple that value would be 1.2
The 'fruitsmaxtobuy' variable is not tied to the first value, but the second one in array.
If you choose Apple that value would be 0.5.
*/
var cash = Math.round(((totalfruitsowned * 0.51 * selectfruit) + 700)*10)/10;
var coupons = Math.round(((totalfruitsowned * 0.51 * selectfruit) + 850)*10)/10;
var cash_all = Math.round((howmanyfruits * cash)*10)/10;
var coupons_all = Math.round((howmanyfruits * coupons)*10)/10;
var fruitsmaxtobuy = Math.round((totalfruitsowned * 0.12 * selectfruit)*10)/10;
/*
Display Error if nothing is entered or if you forget to enter total fruits
*/
if (((howmanyfruits=="" || howmanyfruits==null) && (totalfruitsowned=="" || totalfruitsowned==null)) || ((howmanyfruits==Number(document.getElementById("howmanyfruits").value)) && (totalfruitsowned=="" || totalfruitsowned==null)))
{document.getElementById("cash").innerHTML = "Error";
document.getElementById("coupons").innerHTML = "Error";
document.getElementById("cash_all").innerHTML = "Error";
document.getElementById("coupons_all").innerHTML = "Error";
document.getElementById("fruitsmaxtobuy").innerHTML ="Error"}
else {
document.getElementById("cash").innerHTML = cash;
document.getElementById("coupons").innerHTML = coupons;
document.getElementById("cash_all").innerHTML = cash_all;
document.getElementById("coupons_all").innerHTML = coupons_all;
document.getElementById("fruitsmaxtobuy").innerHTML =fruitsmaxtobuy}
}

hi, I have this keypressed function: Code: function keyPressed(event, input) {
if (event.keyCode == 8) {
return true;
}
var char = event.which ? event.which : event.keyCode;
char = String.fromCharCode(char);
var exers = "1234 1234 1234";
return (exers.charAt(input.value.length) == char);
}
This function allow me to press in order the numbers in array (index0). It is works very well. But i want to add an array with more exercises like: Code: var exerc = new Array();
exerc[0]= "1234 1234 1234";
exerc[1] = "5678 5678 5678";
exerc[2] = "9012 9012 9012";
Also, i have a dropdown menu that parser options from a xml file: Code: <form> <select style="width:100px" id='courses'> </select> </form> and my xml file looks like: Code: <courses>
<course title="exercise 1">
<lesson>1234 1234 1234</lesson>
</course>
<course title="exercise 2">
<lesson>5678 5678 5678</lesson>
</course>
<course title="exercise 3">
<lesson>9012 9012 9012</lesson>
</course>
.
.
.
</courses>
*I write the same index because i have two input field. I see the first choose (depend on dropdown) in first input, and i rewrite the same exercise in the second input. So, it's something like an exercise for me and i stack here. - I repeat. It is work with only one index very well. The problem is that, when i add more that one index in the array. Any suggestion about my problem?Javascript it is not my strong point I try this but it is doesn't work.Baybe it is totally wrong! Code: function keyPressed(event, input) {
if (event.keyCode == 8) {
return true;
}
var char = event.which ? event.which : event.keyCode;
char = String.fromCharCode(char);
var exerc = new Array();
exerc[0]= "1234 1234 1234";
exerc[1] = "5678 5678 5678";
exerc[2] = "9012 9012 9012";
for (i=0;i<exerc.length;i++)
{
document.getElementById("courses").selectedIndex;
}
return (exers.charAt(input.value.length) == char);
}
Hi all I am trying to create a code which stores information about songs The information to be stored are : song ID song name song artist song URL So far what I've done is create an empty array with four properties The code asks the user to enter information and then displays them However i'm having difficulty figuring out how to insert all the information entered in the array. For example if information about 3 songs were entered, how can I insert all of them in the array I created. After storing the information, I want to be able to search for songs by their ID. When I wrote the function to do this, if lets say I entered two songs one with S1 as ID and one with S2 as ID, I type S1 in the search box, but it doesn't return anything. However if I enter S2, it returns the information of the track with this ID, which makes me think that entering information for a second song overwrites the first one This is my code so far: <html> <body> <h1>Tracks and Artists</h1> <script type="text/javascript"> function request(tracks) { for (var i=0;i<2;i++) { tracks.trackID = prompt("Enter track ID") tracks.trackName = prompt("Enter track name") tracks.trackArtist = prompt("Enter artist name") tracks.trackURL = prompt("Enter track URL") alert(display(tracks)) } } function insert() { function display(tracks) { return "Track ID: " + tracks.trackID + "\nTrack name: " + tracks.trackName + "\nTrack artist: " + tracks.trackArtist + "\nTrack URL: " + tracks.trackURL } var tracks = [{trackID: "", trackName:"", trackArtist:"", trackURL:"" }] request(tracks) </script> </body> </html> Hi How can i output two maximum numbers of an array if they are equal? var flower["roses", "violets", "buttercups", "daisies"]; var flowerAmounts[9, 8, 3, 9]; Output should be: The maximum amount of flowers is 9. There are 9 roses and 9 daisies. Hope someone can help, thanks |
