JavaScript - Find Smallest Number In List Of Vars?
If i have 4 vars
var one = 29.1 var two = 5.4 var three = 12.4 var four = 15 how can compare all 4 and find the smallest? in this case the result would be two Similar TutorialsHi there It's huge problem for me but I don't think it is for many of you here. I have been asked at the college to make a manual lottery checker using javascript, but I found lots of problem during the coding. To make it more clear it's about 3 players they always play the same set of 6 number between 1 and 49. the players enter manually the winning number using a prompt which popup when you open the page (No button required for this, just simple prompt). each time you type duplicate number an alert tells that this number been entered, when the six number been successfully entered will ask for the bonus ball the same way but it should between 1 and 49 as well. When this done the program print out for each player the much numbers. This my peace of coding but I stucked in many bits in it. I need your knowledge guys in javascript to fix this for me. Code: <html> <head> <title>Lottery Checker</title> <h1>Lottery Checker</h1> </head> <body> <script type="text/javascript"> //Declare Variable var number1 = [3, 9, 18, 27, 30, 33]; var number2 = [5, 7, 11, 12, 34, 42]; var number3= [4, 15, 21, 23, 27, 31]; var drawNumber = []; var bonusBall = []; //Declare variable Times and Dates var currentTime = new Date(); var day = currentTime.toUTCString(); // Print out the player set numbers document.write("<h4>You visited the lottery website at :</h4>" + day); //Print out Times and Dates document.write('<p>Player number 1 : '+ number1 +'</p>'); document.write('<p>Player number 2 : '+ number2 +'</p>'); document.write('<p>Player number 3 : '+ number3 +'</p>'); //Copare Lottery Number arrays //Add input number using prompt to add the 6 bonus number and the bonus ball for (var i=0 ; i<=5 ; i++) { drawNumber[i] = prompt("Enter the Lottery draw Number."); drawNumber.sort(function(a, b){return a-b}); //Fix the lottery Numbers between 1 and 49 while (drawNumber[i]<1 || drawNumber[i]>49) { drawNumber[i] = prompt("The lottery Number should be between 1 and 49"); // to insert Prompt insteat the Alert } if (drawNumber[i] = drawNumber) // if statement to be checked again { alert('You already entered this number');// if statement to be checked again } } document.write('<p>The winning lottery number for this week: '+drawNumber+ ', The bonus number: '+ drawNumber[6] + '</p></br>'); //Sort the winning number by each player // Display the result for each player how many number much document.write('Player 1 winning numbers: ' + drawNumber +'</br>'); document.write('Player 2 winning numbers: ' + drawNumber +'</br>'); document.write('Player 3 winning numbers: ' + drawNumber +'</br>'); </script> </body> </html> Noob here! I'm doing a little project where i need to take a number (lets say 6), and then I need to find out witch numbers 6 can divided with that equals to a whole number. Any ideas how i can do that? This is what i got in my mind so far: myNum/num === wholeNumber I then need a variable "num" that count all whole numbers from 0 to myNum and a variable "wholeNumber" that works as all whole numbers from 0 to myNum. I really hope you can help me out, thanks Basically I want to factor a number and select the two closest numbers to the middle of the factors for example: 20 factors to 1, 2, 4, 5, 10, 20 I want it to return 4 and 5 If the number is has an odd number of factors (has to be a perfect square) I want it to select the middle number and say it twice for example: 64 factors to 1, 2, 4, 8, 16, 32, 64 I want it to return 8 and 8 Would I use an array or what? My code should probably look like: PHP Code: x = //Factors array y = //number of items in x if (/*y is even*/){ i = y/2 i2 = i+1 a = [i] b = [i2] } else{ i = //somehow the center number? i2 = i a = [i] b = [i2] } So im working on code that user adds things to a list. When you hit the promote button, the user chooses which task to promote to the beginning by way of the unshift method. My problem that I can't figure out is how to get rid of the number to the old task that I promoted. It's like its an empty string. I'm just looking for some ideas to how I might go about solving it. The first code is the html, and the second is the .js. Code: <body> <div id="content"> <h1>Task List Manager</h1> <p id="tasks"><textarea id="task_list" rows="5" cols="50"></textarea></p> <p><input type="button" name="add_task" id="add_task" value="Add Task" /></p> <p><input type="button" name="modify_task" id="modify_task" value="Modify Task" /></p> <p><input type="button" name="delete_task" id="delete_task" value="Delete Task" /></p> <p><input type="button" name="promote_task" id="promote_task" value="Promote Task" /></p> </body> Code: var task_list = []; var $ = function (id) { return document.getElementById(id); } var update_task_list = function () { if ( task_list.length == 0 ) { $("task_list").value = ""; } else { var list = ""; for ( var i in task_list ) { list += (parseInt(i)+1) + ": " + task_list[i] + "\n"; } $("task_list").value = list; } } var add_task_click = function () { $("add_task").blur(); var task = prompt("Enter a task:", ""); if ( task != "" && task != null) { task_list.push(task); update_task_list(); } } var delete_task_click = function () { $("delete_task").blur(); if ( task_list.length == 0 ) { alert("No task to delete."); return; } var to_delete = prompt("Enter the task number to delete:", ""); if (to_delete == null) { return; } to_delete = parseInt(to_delete); if ( isNaN(to_delete) ) { alert("You did not enter a number."); return; } if ( to_delete < 1 ) { alert("The task number is too low."); return; } if ( to_delete > task_list.length ) { alert("The task number is too high."); return; } to_delete--; task_list.shift(); //task_list.splice(to_delete, 1); update_task_list(); } var modify_task_click = function() { var mod = parseInt(prompt("Enter the task number that you choose to modify:", "") ); var wow = parseInt(mod - 1); var bomb = prompt("Modify your task",task_list[wow]); task_list[wow] = bomb; update_task_list(); } var promote_task_click = function () { var mud = parseInt(prompt("Enter the task number that you choose to be promoted:", "") ); var mooh = parseInt(mud - 1); var fat = task_list[mooh]; task_list.unshift(fat); var cops = parseInt(mooh + 1); task_list[cops] = ""; update_task_list(); } window.onload = function() { $("add_task").onclick = add_task_click; $("delete_task").onclick = delete_task_click; $("modify_task").onclick = modify_task_click; $("promote_task").onclick = promote_task_click; update_task_list(); } I have a two fold question: 1) Why would my while statement not be working I have cleaned up my code a little (although not perfect) but my while statement is not behaving, it does not output any numbers on a console.debug (using google chrome, or any other browser for that matter) which from my understanding it should? and 2) Slightly out of the remit of this forum I suppose, but this code is quite lengthy and I know there are ways to make this more efficient I just dont know what they are? Code: function generatePurchaseFields(dom) { new Ajax.Request('/control/?page=tldmaxyears&domain=' + dom, { method: 'get', asynchronous: false, onSuccess: function(transport) { window.maxyears = transport.headerJSON.years.maxterm; window.minyears = transport.headerJSON.years.minterm; } }); var maxyears = window.maxyears; var minyears = window.minyears; //console.debug(minyears + maxyears); var currentyear = minyears; while (currentyear <= maxyears) { console.debug(window.currentyear); console.debug(window.maxyears); if (currentyear == 1) { var surfix = ' Year'; } else { var surfix = ' Years'; } rows += '<option value="' + currentyear + '">' + currentyear + surfix + '</option>'; currentyear++; } var fields = '<input type="checkbox" value="' + dom + '" name="domain[]" />' + '<select name="years">' + '<option value="1">1 Year</option>' + rows + '</select>'; console.debug(rows); return fields; } Kind thanks for any help you may be able to provide. Thanks PodMan99 Question: if I declare a variable in on js fiile, is this available to another js file that is loaded? Answer: yes, it's available (unless inside of a function or something) BUT: does it matter WHERE I declare this variable?? Let's say, I have the following in my HTML file: <script src="script/main.js"></script> And then at the very bottom of my HTML page before the </body> tag I have: <script type="text/javascript">var myvariable = "Sample Data";</script> So, is myvariable available to main.js? In simple tests I've done, yes it does seem to be available But... what if I have a lot of other js code running in between Does this change anything? Thanks OM I have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function: 1: I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100. Does any one know how to code this in my function below in javascript: Code: function insertQuestion(form) { var row = document.createElement("tr"); var cell, input; cell = document.createElement("td"); cell.className = "weight"; input = document.createElement("input"); input.name = "weight_" + qnum; input.onkeypress = "return isNumberKey(event)"; cell.appendChild(input); row.appendChild(cell); } Hi, I'm wondering if it's possible to set a variable to send through with my form using the confirm alert box. Please let me know. Much appreciated. [CODE] <html> <head> <script type="text/javascript"> <!-- function confirmation() { var answer = confirm("Would you like to stay logged into the website? Click OK to stay logged in for your next visit or CANCEL so your login won\'t be remembered.") if (answer){ //how do I set this to rememberMe=1 } else{ //how do I set this to rememberMe=0 } } //--> </script> </head> <body> <form action="test-alert2.cfm" method="post"> <input type="hidden" name="rememberMe" value="rememberMe"> <input type="submit" onClick="confirmation()" value="Login" /> </form> </body> </html> [CODE] Hello all, Sorry for not reading the "posting guidelines" earlier. I understand that you guys are not reading/loading complete codes, my bad. Let me try again. This is a code for checking numbers A1 -> B1, when there is a match, the code will be green, otherwise black. Can somebody explain to me how I can extend this script, that more then one array is checked?? Code: <script type = "text/javascript"> var a1 = ["2","5", "11","16","23","45", "46"]; var b1 = ["2","3","8","12","23", "37", "41", "45", "48"] for (var i = 0; i< a1.length; i++) { for (var j = 0; j< b1.length; j++) { if (a1[i] == b1[j]) { a1[i]= "g"+ a1[i]; } } } for (var i = 0; i< a1.length; i++) { if (a1[i].substr(0,1) == "g") { a1[i] = a1[i].substr(1,20); document.write("<font color = 'green'>", a1[i] + "    "); } else { document.write("<font color = 'black'>", a1[i] + "    "); } } document.write("<br><br>"); for (var j = 0; j< b1.length; j++) { document.write("<font color = 'black'>", b1[j] + "    "); } </script> Thanks a ton in advance I am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689 .toFixed ( 2 ) ==> "15.24" So does it convert the number into string? Hi all, I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County). I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database. This piece of code is working well . . . . Code: <?php $link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error()); mysql_select_db('mydatabase') or die('Could not select database'); if(isset($_GET["County"]) && is_numeric($_GET["County"])) { $County = $_GET["County"]; } if(isset($_GET["Region"]) && is_numeric($_GET["Region"])) { $Region = $_GET["Region"]; } ?> <script language="JavaScript"> function autoSubmit() { var formObject = document.forms['theForm']; formObject.submit(); } </script> <form name="theForm" method="get"> <!-- County SELECTION BASED ON city VALUE --> <?php ?> <select name="County" onChange="autoSubmit();"> <option value=''</option> <?php //POPULATE DROP DOWN MENU WITH COUNTRIES FROM A GIVEN city $sql = "SELECT * FROM county_regions"; $counties = mysql_query($sql,$link); while($row = mysql_fetch_array($counties)) { echo ("<option value=\"$row[CountyID]\" " . ($County == $row["CountyID"]? " selected" : "") . ">$row[County]</option>"); } ?> </select> <?php ?> <br><br> <?php if($County!= null && is_numeric($County)) { ?> <select name="Region" onChange="autoSubmit();"> <?php //POPULATE DROP DOWN MENU WITH RegionS FROM A GIVEN city, County $sql = "SELECT * FROM county_regions WHERE CountyID = $County "; $Regions = mysql_query($sql,$link); while($row = mysql_fetch_array($Regions)) { echo ("<option value=\"$row[CountyID]\" " .

Thanks in advance for your help. I would like to make an ordered list, for example: 1. Airplane 2. Boat 3. Car I'd like one of the words to be displayed on my webpage, for example: Boat Then I'd want an up button, and a down button. The up button would display Airplane instead of Boat, and the down button would display Car instead of Boat. Once it got to Car, the same up button would change it back to boat. How do I do this? Thanks. 09-01-10 Not sure exactly where to post this thread as it involves HTML, Javascript and embedded media players. It probably would be more appropriate here as there is much Javascript involved.... Hello, I am trying to construct a Jukebox for my website. I have spent considerable time all over the WEB and at this forum which addressed the issue in a 50 page thread. Please see: http://codingforums.com/showthread.php?t=50666 I got a lot of ideas from this thread but still cannot figure a way to do the following within the Jukebox. These are my main two questions for everything below: 1. How can I have the Jukebox cycle through all tunes and then start over from the beginning? 2. How can I allow the user to select a tune from a list but not a drop down list, have the Jukebox start from the user’s selection and then play all songs to the end. Then as in #1, start over from the beginning? Per this thread I came away with basically two ways to assemble the jukebox. One uses links in a drop down list which the user can choose from. The other is to use an .m3u playlist. The user can only select a “playlist” from the drop down. Below, I have included the code for each Jukebox. To see the Jukeboxes in action please go to my website where I have posted some test pages exhibiting the jukeboxes that I am referring to. The following is the Jukebox which utilizes an .m3u playlist. If I end up using this idea I would like the tunes in the .m3u playlist to be displayed and allow the user to be able to choose a tune in the list. Then have the list play to the end of all tunes in the list. Then start over from the beginning of the list. After this code is the .m3u playlist.

So far so good, managed to get it to work with only one set of lists, but I actually have 18 of those sets in this form: Code: <select name="fw[$i]" id="fw[$i]"> <option value="1">FWH</option> <option value="3">links</option> <option value="4">rechts</option> <option value="0" selected></option> </select><br /> <select name="lie[$i]" id="lie[$i]" disabled="disabled" onchange="showBox($i,xxx);"> <option value="0" selected>---</option> <option value="1">gut</option> <option value="2">schlecht</option> <option value="3">Strafschlag</option> <option value="4">OB</option> </select> $i is my index generated by my PHP script and runs from 1 to 18. Everything works just fine as long as the index is not in play. With the index my function breaks, most probably due to my inability to extract the second parameter (xxx above) from the selection field. Here's my function, there could be something wrong there too with how exactly to specify the proper dropdown list to enable. Code: function showBox(field,val) { if (val > 1) { var box = 'lie[' + field + ']'; document.form1.box.disabled == false; } else { document.form1.box.disabled == true; } } Finally, I'm not that adept in javascript programming, more like a trial and error guy, how has hit the wall with this problem. Thanks in advance! Joe Hello. Please excuse my ignorance but I am not too clued up on javascript. Im hoping someone may be able to help me out here. I have managed to locate a script which will find text on a page, but I have a couple of requests. Firstly the script will only search up. I would like the search box to be at the top of a page but the only way to get it to work correctly is placing it at the bottom of the page. Secondly would some kind soul advise me how to place the script in an external file and then link to it. Thanks in advance. hi I need to find the average number in javascript.
