JavaScript - Displaying Array Values/calculations Into A Div
Hi all,
Decided to start learning JavaScript, started 2 days ago. Anyway, I'm trying to create a simple script spits out a styled result based on a user input. Here is my JS: Code: function dispTable (form) {
var userCost2 = form.venCost2.value * 1;
marArray = new Array ("0.05", "0.1", ".15", "0.2", "0.25", "0.3", "0.35", "0.4", "0.45", "0.5", "0.55", "0.6", "0.65", "0.7", "0.75", "0.8");
for (var i=0; i<marArray.length; i++) {
document.tableDiv.innerHTML = "<div>"
document.tableDiv.innerHTML = userCost2;
document.tableDiv.innerHTML = marArray[i];
document.tableDiv.innerHTML = + userCost2 * marArray[i];
document.tableDiv.innerHTML = "<\/div>";
}
}
Here is my HTML: Code: <div class="container">
<form name="lasoCalcTable">
<span>Enter Vendor Cost</span>
<input class="textForm" name="venCost2" id="venCost2" type="text" size="8" />
<hr />
<input class="butForm" name="calcTblBut" type="button" value="Calculate" onclick="dispTable()" /><br />
</form>
<div title="tableDiv" id="tableDiv">
</div>
</div>
The problem is that nothing is happening when I press the calculation button. What I would like to happen is to display a div element for each value in the array which displays the entered value from VenCost2, the current Margin %, and the result of VenCost2 * margin%. I want this to display on the same page and underneath the calculation button, preferably not having to reload the page. I thought this was going to be relatively easy but doesn't seem so! Thanks for your help Similar TutorialsI have a form which is used to calculate residential Floor Area Ratio (FAR). The form is structured into seven parts as follows: Part A: Maximum FAR and Floor Area: Part B: Gross Floor Area of the main floors of the main house: Part C: Gross Floor Area of the basement or cellar: Part D: Gross Floor Area of the attic: Part E. Gross Floor Area of all accessory structures except detached garages: (including cabanas, guest houses, caretaker's cottages, pool houses, sheds, barns, or other structures except a detached garage) Part F. Gross Floor Area of the garage: (not including basement garages) Part G: Total Floor Area: The Javascript involved in the calculations is as follows: [CODE] <SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript"> function checkAllInputFields(){ IsValidEntry(entireForm.A1.value) IsValidEntry(entireForm.A5.value) IsValidEntry(entireForm.A6.value) IsValidEntry(entireForm.A8.value) IsValidEntry(entireForm.A9.value) IsValidEntry(entireForm.B1.value) IsValidEntry(entireForm.B3.value) IsValidEntry(entireForm.B4.value) IsValidEntry(entireForm.B5.value) IsValidEntry(entireForm.C1.value) IsValidEntry(entireForm.C2.value) IsValidEntry(entireForm.C3.value) IsValidEntry(entireForm.D3.value) IsValidEntry(entireForm.D4.value) IsValidEntry(entireForm.D6.value) IsValidEntry(entireForm.D7.value) IsValidEntry(entireForm.D9.value) IsValidEntry(entireForm.D10.value) IsValidEntry(entireForm.D12.value) IsValidEntry(entireForm.D13.value) IsValidEntry(entireForm.D14.value) IsValidEntry(entireForm.D15.value) IsValidEntry(entireForm.E1.value) IsValidEntry(entireForm.F2.value) IsValidEntry(entireForm.F3.value) IsValidEntry(entireForm.F4.value) IsValidEntry(entireForm.F5.value) IsValidEntry(entireForm.F8.value) IsValidEntry(entireForm.F9.value) IsValidEntry(entireForm.F11.value) IsValidEntry(entireForm.F12.value) IsValidEntry(entireForm.F14.value) IsValidEntry(entireForm.F15.value) IsValidEntry(entireForm.F17.value) IsValidEntry(entireForm.F18.value) IsValidEntry(entireForm.F19.value) IsValidEntry(entireForm.F20.value) } function IsValidEntry(entry){ if(entry == "N/A to this property" || entry == "" || IsNumeric(entry)){ //do nothing } else{ alert(entry + " is not a number.

And I want to resolve it..I don't want to display NaN values. instead of NaN I just want it blank. here is my code: Code: function doz(oText){
var P27_max = document.getElementById("P27_max").value;
var P27_max_convert = parseFloat(P27_max) + parseFloat(1);
var P27_maxdoz = document.getElementById("P27_maxdoz").value = P27_max_convert;
var P28_max = document.getElementById("P28_max").value;
var P28_max_convert = parseFloat(P28_max) + parseFloat(2);
var P28_maxdoz = document.getElementById("P28_maxdoz").value = P28_max_convert;
}
when I entered data in P27_max so the P27_maxdoz was computed but the problem is the P28_max has also value 'NaN'. How can I eliminate or did not display NaN Thank you 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> 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. Code: function sortArrayGo(startingArray, sortNum)
{
var holder = startingArray;
//holder.push(startingArray[0]);
var sortedArray = new Array();
var endNum = startingArray.length;
//indexPlace=0;
for(n = 0; n < endNum; n++)
{
var min = 0;
for(m=1; m<holder.length; m++)
{
alreadyMin = holder[min][sortNum];
possibleMin = holder[m][sortNum];
if(alreadyMin > possibleMin)
{
min = m;
}
}
thisLine = startingArray.splice(min, 1);
for(cellCount = 0; cellCount < tablePos.length; cellCount++)
{
colNum = tablePos[cellCount];
dataToInsert = thisLine[colNum];
document.getElementById('dataTable').rows[n].cells[cellCount].innerHTML = dataToInsert;
}
sortedArray.push(thisLine);
}
return sortedArray;
}
i'm sorting a 2d array by whatever column i specify. i know from using firebug that my sorting is working, but it's getting and displaying undefined for dataToInsert and inside of my table, but sortedArray winds up sorted correctly. thank you
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 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">

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("cash_all").innerHTML = "Error";

document.getElementById("coupons").innerHTML = coupons;
document.getElementById("cash_all").innerHTML = cash_all;

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);
}
Hey, i am just trying to learn javascript and my friend gave me a little assignment to try and figure out. i am having trouble figuring it out and need some help. basically i just want to display the information in my associative array, into an html table. var NFC_east = new Array(); NFC_east[0]=["Giants", 16, 0, "Eli Manning"]; NFC_east[1]=["Cowboys", 0, 16, "Tony Romo"]; NFC_east[2]=["Redskins", 0, 16, "Donnovan McNabb"]; NFC_east[3]=["Eagles", 0, 16, "Mike Vick"]; that's my array. now i need to display that in a table with a Team column, wins column, loses column, and a quarterback column. i basically want to do this using a for loop, and he gave me a hint about using a nested while loop as well somehow. i know i need to use getElementById, id, and innerHTML stuff but i just don't know how to do it. i cant find anything to help me with this simple task, hoping someone here could help. Hi all, I want to display varying company information from a javascript array randomly each time the page is refreshed. My problem is that the each piece of company information must be split up into 3-4 array elements since I have set up spans in the body where the information go accordingly and as such I don't how to randomize that. The relevant code is (I will only give two company examples as it's a long list): Code: <script type="text/javascript" language='javascript'>
function compInfo(comp){
var companyInfo = new Array();
if(comp == document.getElementById('test').innerHTML)
{
//insert business name here.
companyInfo[0] = 'Test';
//insert business type here.
companyInfo[1] = 'Media';
//insert street name here.
companyInfo[2] = 'Test Road.';
//insert actual opening time here.
companyInfo[3] = '5am - 10pm';
//insert actual closing time here.
companyInfo[4] = 'Christmas';
//insert contact info here.
companyInfo[5] = 'test';
//insert web address here.
companyInfo[6] = '<a href="http://www.test.com" style="color: #0092DD; text-decoration: none;">test.com</a>';
//insert image link here.
companyInfo[7] = 'images/test.jpg';
}
if(comp == document.getElementById('test1').innerHTML)
{
//insert business name here.
companyInfo [0] = 'Test1';

So essentially the process is: 1. The person clicks on the company name. 2. Relevant information from the array is shown in the div. But what I want is that on startup, information about a random company is shown automatically. How can I achieve this? Thanks. Hello, I have an array containing 100 different values. How would I randomly pick 25 of them for display? For now I do: PHP Code: 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. Thanks in advance! PS. My array could also contain only 20 values, in which case I would like the function to display the 20 values randomly sorted. hi, i am currently working on aptana stuidio Nokia WRT to create a mobile widget. the projects requires the retrieval of data from a database. I've created a java servlet in eclipse to connect and execute query to the database. In aptana, i'm using js file and html file. i am able to connect to the servlet, process the data (split it) and store in an array to display the retrieved data on screen. But now i am facing problems to put the retrieved data (array) into a drop down list for selection. can i do it in a js file? thanks =) hi guys i hava gridview gvcustomers with following fields latitude,longitude,customer and i have a javascript function in my aspx page fucntion Customer() { AddCustomer(lat1,long1)--- row1 of gridview lat long AddCustomer(lat2,long2)--row2 of gridview lat long } in the above function i would like to loop through the gridview and get the latitude and longitude colmns in the function instead of hardcoding as i have been doing now...thank you i advance I am a beginner.

So I am working on an excercise that the User puts in a Lastname, Firstname, and a score via textboxes. When the user pushes the add student score it should show up in the text area with this format " Brown, John: 92". When looking at the logic, I understand that each text box will need to be different arrays if im right, and then I will have to concat all three arrays into the format and assign it to a variable. Then assign the variable to the value of the text area. I just cannot seem to put the function together or how you would go about it. I just need help with how to go about putting it together. The first code is my body of HTML I'm working with. Code: <body>
<div id="content">
<h1>Student Scores</h1>
<div id="buddy">
<b>Last Name: </b><input type="text" id="lastName" />
<b>First Name: </b><input type="text" id="firstName" />
<b>Sco </b><input type="text" id="score" />
<input type="button" id="calculate" value="Add Student Scores" />
</div>
<fieldset>
<legend>Student Scores</legend>
<p id="tasks"><textarea id="task_list" rows="20" cols="100"></textarea></p>
</fieldset>
<div id="yoohoo">
<b>Average sco </b><input type="text" id="averageScore" />

<div id="yes">
