JavaScript - Need Help With Nested Else-if Statements
This may be a basic programing problem but I am writing a function to validate a form using a bunch of else-if statements and encounters a problem when I use nested if/else-if statements. It will not continue on to the next else-if, after it returns false.
Code: // to check each entry on the form and alert user if entry is invalid.
function checkform(){
var checkssn = /(\d{3})-(\d{2})-(\d{4})/;
var checkphone = /(\d{3})-(\d{4})/;
var checkname = /[a-zA-Z]+(\.|,|\s)*/;
var checkzip = /(^967|^968)\d{2}(-\d{4})?$/;
// check to see if user have selected an Election
if (!document.f1.elections[0].checked && !document.f1.elections[1].checked && !document.f1.elections[2].checked && !document.f1.elections[3].checked) {
window.alert("Please select an Election!")
return false;
// check to see if user entered a valid SSN
} else if ( checkssn.test(document.f1.ssn.value) == false){
window.alert("[1]. Please enter a valid social security number in the format ddd-dd-ddd");
return false;
// check to see if user entered a valid home telephone number or business telephone number
}else if ( document.f1.home_phone.value == '' && document.f1.business_phone.value == '') {
window.alert("[4]. Please enter a Home or Business telephone number!")
return false;
} else if ( document.f1.home_phone.value != ''){
if (checkphone.test(document.f1.home_phone.value) == false){
window.alert("[4]. Please enter a valid home phone number in the format ddd-ddd");
return false;
}
} else if ( document.f1.business_phone.value != ''){
if ( checkphone.test(document.f1.business_phone.value) == false){
window.alert("[4]. Please enter a valid business phone number in the format ddd-ddd");
return false;
}
// check to see if user entered a valid Name
}else if ( checkname.test(document.f1.lastname.value) == false){
window.alert("[5]. Last Name can only consist of letters, periods(.), commas(,) and spaces");
return false;
}else if ( checkname.test(document.f1.firstname.value) == false){
window.alert("[5]. First Name can only consist of letters, periods(.), commas(,) and spaces");
return false;
The problem occurs when it validates the phone numbers. When a valid number is entered, it will not move to the next else-if statement to validate the name. It's been years since I program in Java/C, so I'm a bit rusty. Any help is appreciated. -Alex Similar TutorialsHi I need help to finish this code with using nested if statements A price of a ticket to a passenger will be: First Class 500 Economy Class (with meal) 400 Economy Class (without meal) 200 How I can write a JavaScript code according to the following specifications: a. Read the class that the passenger wants to travel on. b. If the class is the first class, print the price of ticket. c. If the class is the economy class, ask the user if he/she wants a meal on the flight. Then print the price of the ticket according to the response of the passenger. The program should simply accept one possible strings the user enters; it is not required to work for all possible inputs such as First, first, FIRST or Yes , yes, YES. This is the code which I have been trying { var inputNum = prompt("Enter the class you want\n first class?\neconomy? :"); if (isNaN(inputNum)) { if (inputNum.match(/first class/)) { document.write("<h1><center>your Ticket is 500<\center><\h1>"); } else { prompt("<h1>if you want a meal on the flight press OK <\h1>"); document.write("<h1>your ticket is 400<h1>,"); } } Im trying to figure out why this code won't work. Unsuccessfully. Sorry, didn't know how to use the "CODE" tag. <html> <head> <script type:"text/javascript"> var BGColor = prompt("Would you like the background of the page to be red, green, or blue?","") </script> </head> <body> <script type:"text/javascript"> if (BGColor == "red") { document.write('<body bgcolor= "red">The body of this page is RED. Press F5 to restart!') } else if (BGCOlor == "green") { document.write('<body bgcolor= "green">The body of this page is GREEN. Press F5 to restart!') } else if (BGColor == "blue") { document.write('<body bgcolor= "blue">The body of this page is BLUE. Press F5 to restart!') } </script> </body> </html> Give me an example for switch statements. I had to create one that tests value of parameter using a text string, I came up with this value Code: function createBar(partyType,percent){
switch(partyType) {
case D: <td class='dem'></td>
break;
Should I use " or ' between the dem? I am using break statements. do all breaks should end with string or do i need the bracket? I hope this does not seem like i getting people to do homework for me again,, just want to verify if i did this area correctly? Code: <html>

I am having trouble getting this to work properly. What I am trying to do is come up with a simple vat deduction + student discount calculator. I cannot seem to get it working. edit:: got it to work setting inBooth to false in the function where I clear the menu, but then it's refreshing to div so often while you're standing in the booth (30 frames/sec, it's a game) that nothing happens when you click the buttons to buy/sell unless you click really really fast.... anyone know a good way to check whether something is true, then toggle an innerHTML div, then once the value becomes false, toggle the innerHTML div to empty....??simply?? But if I reverse the order the opposite works but then the other doesn't...... Code: if (condition==true ) {
generateSale();
inBooth=true;
smithShop();
} else {inBooth=false;clearSale();}
//IS PLAYER IN VENDOR BOOTH?
if (condition2==true ) {
generateSale();
inBooth=true;
vendorShop();
} else {inBooth=false;clearSale();}
Only the "generateSale()" from the second one executes. If I switch the if blocks, the second one with "generateSale()" executes. If I change "clearSale();" to a "setTimeout=('clearSale()',1000)" then both execute "generateSale()" but the div it affects flickers repeatedly as it's cleared/remade. generateSale() changes the innerHTML of a div, clearSale() just overwrites the innerHTML with ' ' Code: var sales2;
function clearSale() {
sales2=document.getElementById('sales2');
sales2.innerHTML='';
}
function generateSale(){
sales2=document.getElementById('sales2');
sales2.innerHTML=
'Buy/Sell: '+' Gold coins: '+playerInventory[lootArray[7]]+'<br>'
+' Consumables:<br>'
+'You have: '+playerItems[itemArray[4]] +' arrows<br>'
+'<input type="button" value="Buy" onclick="buyIt(0);">'+'10 for 50gp<br>'
+'<input type="button" value="Sell" onclick="sellIt(0);">'+'10 for 25gp<br>'
}
Any ideas? Basically when my character enters the range of an image of a building I have a menu pop up saying you're in a vendor booth. I want it to run generateSale() which changes a div on the screen to list a bunch of stuff you can buy/sell. When your character is no longer standing in range, I want it to clear that information, so you have to be standing within range in order to trade items. Currently I can make it generates the sale menu, but it doesn't clear it when you leave the range. I've tried all kinds of "toggle" variables to set whether you're in range or not, but only the second block fires, not the first and I cannot figure out why... Any ideas? The code all works fine it just won't clear for all the different buildings, only one.... Okay, so I got this code originally from another site. (A few months ago) I don't remember the site, and I was wondering if anyone could help me get it back how it was. Originally I believe the if statements were like this: Code: if (hr == 6, 7, 8)
document.write("")
I want the same code to appear when any of these numbers appear. Here is my current code: Code: document.write("<center><font size=+1>")

hr = day.getMinutes()

I'm really new to this and I'm trying to figure out how to sum the two values from if statements. ParseInt is returning NaN. Before that, it was adding my results together as strings. Is there an easy way to add these together without creating a very complicated if statement to total these up? Thanks! Here is the code, in full: <htmll"> <head><title></title> <script type="text/javascript"> <!-- HIDE FROM INCOMPATIBLE BROWSERS function checkGrade(grade, value) { switch (grade) { case "A": if(grade == '90') window.alert("Your grade is excellent."); break; case "B": window.alert("Your grade is good."); break; case "C": window.alert("Your grade is fair."); break; case "D": window.alert("You are barely passing."); break; case "F": window.alert("You failed."); break; } } // STOP HIDING FROM INCOMPATIBLE BROWSERS --> </script> </head> <body> <form name="gradeForm"action="Your Grades"> <input type="text" name="grade" /> <input type="button" value="Check Grade" onclick="checkGrade(document.gradeForm.grade.value);" /> </form> </body> </html> What's throwing me off is the "A" in the case. As well, "(document.gradeForm.grade.value)" I need to make it a IF statement, but not sure how to call that function. Hi, been using javascript for a while now, and wondering how else this could be coded to be more effective and to 'work'. The idea is that the user gets prompted, 'what is your birthday?' the user would put in 0121 or whatever their birthday is, as 01 = month and 21 = day. I'm sure you'll understand what I mean.... Code: <DOCTYPE html>
<html>
<script>
var userAnswer = prompt("When is your birthday? Example: Jan 21st = 0121")
</script>
<head>
</head>
<body>
<script>
if(userAnswer >= 0101){
alert('You are Capricorn!') };
if(userAnswer >= 0120){
alert('You are Aquarius!') };
if(userAnswer >= 0219){
alert('You are Pisces!') };
if(userAnswer >= 0321){
alert('You are Aries') };
if(userAnswer >= 0420){
alert('You are Taurus') };
if(userAnswer >= 0521){
alert('You are Gemini!') };
if(userAnswer >= 0621){
alert('You are Cancer!') };
if(userAnswer >= 0723){
alert('You are Leo!') };
if(userAnswer >= 0823){
alert('You are Virgo!') };
if(userAnswer >= 0923){
alert('You are Libra!') };
if(userAnswer >= 1023){
alert('You are Scorpio!') };
if(userAnswer >= 1122){
alert('You are Sagittarius!') };
if(userAnswer >= 1222){
alert('You are Capricorn!') };

Join Date Jun 2002 Location London, England Posts 18,371 Thanks 204 Thanked 2,573 Times in 2,551 Posts If you have been using Javascript for a while now, you should be aware that prompts and alerts are long obsolete, and I would advise that you should not be wasting your time learning this stuff. Use DOM methods to obtain input from and display messages to your users. Be aware that a value starting with 0 is a string, not a number, and so must be in quotes - that is why your code does not work. In any case you need rigorous checking to ensure that the birthday entered in this form is valid, e.g. not 56th Febtember or "Mickey Mouse". You would do best to obtain the input from select lists for month and day, expressed as numbers. A tiny bit more sophistication would allow the user to select a month by name, where the text of the option is the month name, and the value of that option the month number. Code: <select id = "monthlist" onchange = "getSignFunction()"> <option value = "0"> Choose your birth month</option> <option value = 1>January</option> <option value = 2>February</option> ... and so on </select> Then you want something like this:- Code:
function getSignFunction()"{
var sign = "";
var month = document.getElementById("monthlist").value;
var date = document.getElementById("datelist").value;
if (month == 0) {return} // invalid choice
if (month == 1 && date >=20 || month == 2 && date <=18) {sign = "Aquarius";}
if (month == 2 && date >=19 || month == 3 && date <=20) {sign = "Pisces";}
if (month == 3 && date >=21 || month == 4 && date <=19) {sign = "Aries";}
if (month == 4 && date >=20 || month == 5 && date <=20) {sign = "Taurus";}
if (month == 5 && date >=21 || month == 6 && date <=21) {sign = "Gemini";}
if (month == 6 && date >=22 || month == 7 && date <=22) {sign = "Cancer";}
if (month == 7 && date >=23 || month == 8 && date <=22) {sign = "Leo";}
if (month == 8 && date >=23 || month == 9 && date <=22) {sign = "Virgo";}
if (month == 9 && date >=23 || month == 10 && date <=22) {sign = "Libra";}
if (month == 10 && date >=23 || month == 11 && date <=21) {sign = "Scorpio";}
if (month == 11 && date >=22 || month == 12 && date <=21) {sign = "Sagittarius";}
if (month == 12 && date >=22 || month == 1 && date <=19) {sign = "Capricorn";}
alert (sign); // alert used here just for testing purposes. Crate as <span> and then use document.getElementById("spanid").innerHTML = sign to display the result to the user.
}
All advice is supplied packaged by intellectual weight, and not by volume. Contents may settle slightly in transit. Trying to check validation on some dropdowns with this but man it's ugly. Is there a way to make it cleaner? Code: function checkDrop() {

Hi, I am trying to detect a users browsers and output a different code based on browser. I found this code online that uses the object detection method and it works. When I document.write(BrowserDetect.browser) it outputs Chrome, (which is what I am using). The code can be found he http://www.quirksmode.org/js/detect.html So I can't understand why the following code does not work? It ouputs the "not" in the else statement. I believe that BrowserDetect is an object and the .browser at the end is a property of the object. Can one not make an object a variable? or make an object a string? oh and BTW there is a bunch of javascript that creates the browserdetect object that can be found on the site above, but I thought it would be too unwieldy to post here. Thanks. The following script outputs: Chrome Not Working <script type="text/javascript"> document.write(BrowserDetect.browser); var browser="BrowserDetect.browser"; if(browser=="Chrome") { document.write(" Working"); } else { document.write(" Not working"); } </script> Hello, I have a long string of if..else statements, and the same is used in multiple functions. How do a make a variable that I can call instead of copying 40 lines of code? Thanks!

Basically I want to make it so that if you click about, and about is open, once you click contact it closes about before opening contact? I'm not sure how to approach this though whether I should use if statements or something? I'm pretty new to jquery I need to create javascript that will create the ringup line (see code) based on accomodation selections. If they chose Wednesday as arrival and depart Thursday they will get the breakdown_wed_supplement value. If they arrive Wednesday and depart later than Thursday they will get charged for Wed and Thursday and finally if they arrive Thursday, they will get charge for Thursday. The Friday - Sunday values are working, but I can't get the Wed/Thurs to work. They were written by someone else and were working, but I needed to change it for the Thursday departure. I am really new to javascript and haven't got a clue where I went wrong. Code: if (getControlValue(form.accommodation)==="Yes") {
if (getControlValue(form.occupancy)==="Single") {
total.ringup(conferencePrices.lodgingFeeConference,'Conference lodging for single person, Friday through Sunday','breakdown_lodging');
} else if (getControlValue(form.occupancy)==="Double") {
total.ringup(conferencePrices.lodgingFeeConferenceRoommate,'Conference lodging with roommate, Friday through Sunday','breakdown_lodging');
}
if (form.arrivedate.selectedIndex===1 && form.departdate.selectedIndex===2) {
if (getControlValue(form.roommate)==="Assign" || form.rm_arrive.selectedIndex===1 && form.rm_depart.selectedIndex===2) {
total.ringup(conferencePrices.lodgingFeeNightlyRoommate,'Wednesday pre-conference lodging, with roommate','breakdown_wed_supplement');
} else {
total.ringup(conferencePrices.lodgingFeeNightly,'Wednesday pre-conference lodging, single person','breakdown_wed_supplement');
}
}
if (form.arrivedate.selectedIndex===1 && form.departdate.selectedIndex===>2) {
if (getControlValue(form.roommate)==="Assign" || form.rm_arrive.selectedIndex===1 && form.rm_depart.selectedIndex===>2) {
total.ringup(conferencePrices.lodgingFeeNightlyRoommate,'Thursday pre-conference lodging, with roommate','breakdown_thurs_supplement');
total.ringup(conferencePrices.lodgingFeeNightlyRoommate,'Wednesday pre-conference lodging, with roommate','breakdown_wed_supplement');
} else {
total.ringup(conferencePrices.lodgingFeeNightly,'Thursday pre-conference lodging, single person','breakdown_thurs_supplement');
total.ringup(conferencePrices.lodgingFeeNightly,'Wednesday pre-conference lodging, single person','breakdown_wed_supplement');
}
}
if (form.arrivedate.selectedIndex===2) {
if (getControlValue(form.roommate)==="Assign" form.rm_arrive.selectedIndex===2) {
total.ringup(conferencePrices.lodgingFeeNightlyRoommate,'Thursday pre-conference lodging, with roommate','breakdown_thurs_supplement');

I'm a little new to Javascript so I apologise if this is an easily resolved problem. This is my Javascript code: Code: function display(){
if(document.getElementById('one').style.display="none"){
document.getElementById('one').style.display="block";
}
else if(document.getElementById('one').style.display="block"){
document.getElementById('two').style.display="block";
}
else{
document.getElementById('three').style.display="block";
}
}
This is my HTML: Code: <html>
....
<style>
#one,#two,#three {
display:none;
}
</style>
....
<ul>
<li id="one">1</li>
<li id="two">2</li>
<li id="three">3</li>
<li id="click" onclick="display()">+</li>
</ul>
The idea is when I click the list item 'click' the display() function will be called and make list item 'one' appear. If list item 'one' is already visible however, list item 'two' will appear, etc. When I click it, list item one appears fine as it should, but if I click it again list item two does not appear, and I can't work out why. I could really do with some help, thank you in advance! can someone see a way to minimize this down to one statement that makes it infinate? if(x == i) || (x*1 == i) || (x*2 == i) || (x*3 == i) || (x*4 == i) || ............. x is a var user input. it is numeric. i is the counter placed above the function. I have an order form which is validated by javascript... To validate the fields I have used multiple if statements! But the problem is it works well when checking the fields from top to bottom; but if the user leaves all the upper fields blanks and only inputs the last field, the script fails to validate all the upper fields.. Please help me improve my javascript... The javascript code is validatecalculate.js Code: function setFocus()
{
document.getElementById("fname").focus()

function IsNumeric(strString)
// check for valid numeric strings

var strValidChars = "0123456789 ";//allowed numeric and space

Hello! I'd like to ask if it is possible to use conditional operators var = condition ? var1 : var 2 to do the same job as the if-else statements I wrote in red below: Thank you! Code: <p id="text">change text colour</p>
<br />
<a onclick="allsorting();">sort in both ascending & descending orders</a>
<div></div>
<script>
/* if & else */
function changetext(){
document.getElementById('text').onclick = function (){
swapcolour(this);
}
}
function swapcolour(text){
if(text.style.color == 'black'){
text.style.color = 'red';
}
else {text.style.color = 'black'}
}
window.onload = changetext;
</script>
Currently I have the following javascript switch statement ... Code: switch(firstchar){
case "0": case "1": case "2": case "3": case "4": case "5": case "6": case "7": case "8": case "9":
orderlist[0] += addthis; break;
case "a": case "A": orderlist[1] += addthis; break;
case "b": case "B": orderlist[2] += addthis; break;
case "c": case "C": orderlist[3] += addthis; break;
case "d": case "D": orderlist[4] += addthis; break;
case "e": case "E": orderlist[5] += addthis; break;
case "f": case "F": orderlist[6] += addthis; break;
case "g": case "G": orderlist[7] += addthis; break;
case "h": case "H": orderlist[8] += addthis; break;
case "i": case "I": orderlist[9] += addthis; break;
case "j": case "J": orderlist[10] += addthis; break;
case "k": case "K": orderlist[11] += addthis; break;
case "l": case "L": orderlist[12] += addthis; break;
case "m": case "M": orderlist[13] += addthis; break;
case "n": case "N": orderlist[14] += addthis; break;
case "o": case "O": orderlist[15] += addthis; break;
case "p": case "P": orderlist[16] += addthis; break;
case "q": case "Q": orderlist[17] += addthis; break;
case "r": case "R": orderlist[18] += addthis; break;
case "s": case "S": orderlist[19] += addthis; break;
case "t": case "T": orderlist[20] += addthis; break;
case "u": case "U": orderlist[21] += addthis; break;
case "v": case "V": orderlist[22] += addthis; break;
case "w": case "W": orderlist[23] += addthis; break;
case "x": case "X": orderlist[24] += addthis; break;
case "y": case "Y": orderlist[25] += addthis; break;
case "z": case "Z": orderlist[26] += addthis; break;
default: alert('Illegal Entry'); break;
}
... that I wish to optimize so that I do not need to write out so many lines of code. Also, I wish to take into the following as consideration ... Code: case "aa": case "Aa": case "aA": case "AA": orderlist[1] += addthis; break; ... for each two-character combination. (aa to zz) Appreciate any help. |
