JavaScript - The Case Construct, Please Help.

Wrote this code out and it doesnt function correctly but I cannot see nefin wrong with it:

<script type="text/javascript">

var choice;
var startTag;
var endTag;
var validInput;
var listType;

choice = window.prompt("Select a list style:\n" + "1 (numbered), 2 (lettered), 3 (roman)", "1");

switch (choice)
{
case "1":
startTag = "<ol>";
endTag = "</ol>";
listType = "<h1>Numbered List</h1>";
break;

case "2":
startTag = "<ol style = \"list-style-type: upper-alpha\">";
endTag = "</ol>";
listType = "<h1>Lettered List</h1>";
break;

case "3":
startTag = "<ol style = \"list-style-type: upper-roman\">";
endTag = "</ol>";
listType = "<h1> Roman Numbered List</h1>";
break;

default:
validInput = false;
}

if ( validInput == true )
{
document.write(listType + startTag);

for (var i = 1; i <= 3; ++i)
document.write("<li>List Item " + i + " </li>" );

document.write(endTag);
}
else
document.write("Invalid choice: " + choice);

</script>

Code:

var areas = {
  "The Plains of CASCADIAN": { yMin:  0, yMax: 20, xMin:  0, xMax: 24 },
    "The Forests of BELGROS": { yMin:  0, yMax: 34, xMin:  24, xMax:50  },
	"Bewitched VOLRAP": { yMin:  0, yMax: 42, xMin:  50, xMax:100  },
	"The Moutains of MELDROSS": { yMin:  26, yMax: 52, xMin:  0, xMax: 48 },
	"The Moutains of OLAP": { yMin:  49, yMax: 68, xMin:  0, xMax: 48 },
	"The Swamps of NEMBRESS": { yMin:  54, yMax: 90, xMin:  44, xMax: 100 },
	"The Great Wood of OLKLEMPT": { yMin:  62, yMax: 100, xMin:  32, xMax: 100 },
     "Dark Forests of MURLAP": { yMin:  60, yMax: 100, xMin:  0, xMax: 42 },
	"Imperial MANTRIOCK": { yMin:  22, yMax: 58, xMin:  44, xMax:100  }
}

How would you reffer to the areas with a javascript if statment or case?

I am having trouble with the following:
Code:

<script language="javascript" >
function premium_calculator()
{
	var val = document.getElementById('user_input').value;	
	var state = document.getElementById('user_state').value;

alert ( state );
//                if (state=1) 
//                           alert ("QLD");
//               else 
//               if (state=2)
//                          alert ("NSW");
//              else
//                        alert ("ACT");
            

             switch (state) {
               case 1: alert ("QLD"); break:
               case 2: alert ("NSW"); break;
               case 3: alert ("ACT"); break;
             }


	document.getElementById('val_100_1').innerHTML =0;
	document.getElementById('val_250_1').innerHTML = 12;
	document.getElementById('val_500_1').innerHTML = 13;
	document.getElementById('val_1000_1').innerHTML = 14;

}

the above code produces nothing, no alert messages and no returned elements. can be seen here http://www.scubaservice.com.au/calculation-test-2.html

If I comment out the switch statement entirely and use the if statement; the first alert statement will produce a 1,2 or 3 depending on input but the second alert is always "QLD".

There are several calculations for each of the returned values and these will be different depending on the state selected. The basis for the calculations work on their own ie for 1 state. http://www.scubaservice.com.au/calculation-test.html

Any help to get this working would be apreciated.

Greetings,

I am new to these forums, and am wrapping up a JavaScript class for the year.
I am in desperate need of help (which I usually obtain from my Instructor, but she is away from the office today) with my Tutorial 12, Case Problem 1 : New Perspectives JavaScript and AJAX 2nd Edition( by Patrick Carey). I am running xampp as my testing environment, and using Dreamweaver CS4 to write my code.

I've completed the code work, however I am having issues with Step 6 code.

6) Add the retrieveOrders() function. Within this function, do the following:
a. Create variables named user, pwd, sButton, and orderHistory to refrence the elements on the Web page with ID values of userID, pwd, submitButton, and orderhistory, respectively.

b. Add and event handler to the sButton object that runs when the button is clicked. Steps c through e should all be done within this event handler.

c . Create variables named userValue and pwdValue equal to the values entered into the user and pwd input boxes. respectively.

d. If userValue and pwdValue both are non-empty, create a request object named reqOrders. Using the get method, open the following URL with the request object /cgi-bin/wworders.pl?user=userValue&pwd=pwdValue
where userValue and pwdValue are the values of userValue and pwdValue variables, respectively.

e. Send the request and then wait for a complete and error-free response from the server. When the response arrives, store the text of the response in the orderHistory object on the Web page.

Here is the code from my html file and my .js file(s)
NOTE: I had to copy the addEvent function from wwlibrary.js to eliminate an error of addEvent not defined.

Hello

I have issue and question.

My software is taking value "inputVal" and assign it to the variable inputValue for example: assdsf


than


value "inputTyp" and assign it to the variable inputType for example: string


so I want now to switch betwean "inputType" using "switch case"
Every case has some "code" inside.

So if my software choosed for example: inputType which is for example STRING value

I want to RUN case 'string':

But it doesn;t works ;/

It doesn't goes to any case;/

what is wrong with the code ;/

every case should test according regular expressions is string a string or email is email or number is number etc... and result: "false or true" should be assign to new variables for example "inpNUMBER" "inpEMAIL" etc.

please help

here is a code


Code:

inputValue = scriptletContext.getLocal("inputVal");
inputType = scriptletContext.getLocal("inputTyp");

//scriptletResult = inputType; 

switch (inputType)

{

case 'number': scriptletResult=("inpNUMBER",/^[-+]?\d+(\.\d+)?$/.test(inputValue)); 
//scriptletContext.put("inpNUMBER",/^[-+]?\d+(\.\d+)?$/.test(inputValue));  


case 'email': scriptletResult=("inpEMAIL",/^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[(2([0-4]\d|5[0-5])|1?\d{1,2})(\.(2([0-4]\d|5[0-5])|1?\d{1,2})){3} \])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/.test(inputValue));

case 'string': scriptletResult=("inpALPHA",/^[a-z0-9]+$/.test(inputValue)); 
//scriptletContext.put("inpALPHA",/^[a-z0-9]+$/.test(inputValue));  


case 'ip': scriptletResult=("inpIP",/^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)+$/.test(inputValue));

please give me the code for checking the company name entered in textbox using javascript .Only sentence case to be allowed.Only abbreviations (without a full name) should not be allowed.(eg DPS) Abbreviations if any should be allowed only at the end of the name within ().eg Delhi Public School(DPS)

I am returning the present time - then using the .substr to remove all digits except the last two on the right (i.e effectively returning the value 32 from 65344532) I am then looping, subtracting 11 from that number until the value is less than 11. The intent being to then return the value from the appropriate matching array ID

I have an array sl1
sl1[0]; sl1[1]; sl1[2]; sl1[3]; sl1[4]; sl1[5];
sl1[6]; sl1[7]; sl1[8]; sl1[9]; sl1[10];

The problem arises with evaluating two digit numbers beginning with zero - In cases where the last two numbers are greater than 09, the looping returns a 1 digit number for valuse less than 10, in cases where the last two digits begin with zero the loop will not begin. I have attempted to use the switch(n) to determine if any 01, 02, 03 ... etc exists but this is not evaluating correctly - is this due to using the date/time object and if so is there a good way to convert this to either a numeric or string datatype where the case can be evaluated correctly? Thanks in advance!

So, I have a list of items that need to have a new preset list item appear based on what day it is. I have the date script working (to test, change the first case to some random date and change the third case to todays date - 10192010 - It will fire that document.write). What I need the cases to do though, is set the visibility of certain list items.

This is just an example, there will be around 20 list items in the final project. As you can see in the first two cases, I've tried a couple different routes to no avail. Any help would be fantastic.

The Code (class references are irrelevant to this example, they belong to the final project):

I'm a bit of a hack at this. Any input is greatly appreciated. Thanks again.

Here is what i'm trying to do and I'm not sure if it will work with a switch, but i'd be better than writing a million if else statements.

Code:

var = c
var = z

switch (c)
{
case c > 1 && < 10:
z = 5;
break;
case c > 10 && < 20:
z = 15;
break;
default:
z = 0;
}

I think you see what I'm trying to do. I have a variable 'c' and it is input by the user and I want to make variable 'z' set according to what 'c' is. I know the above code doesn't work, but I'm not sure why. I've tried a million different things to try and get it to work, but it always just goes to default when it displays 'z'. Any help would be great. Thanks.

Seniors
Plz help me resolve a little problem i.e. i need to enter either capital or small letter the input should be accepted.
The code is written below:
Plz help me solve this.

var Alphabet;

Alphabet= prompt("Enter an Alphabet");

Hello.

I need to manipulate with a upper and lower case on STRINGS

For example I have string:

Code:

LALA_KAKA_mama_WIWI

I need to conwert it to

Code:

Lala_kaka_mama_wiwi

with first letter upper case.

Is it one simple way to do it with JS script/code?


Best Regards

I'm currently attempting to make a unit conversion tool. I'd like for the user to select which unit to start and which unit to convert too. EX: 1 foot comes out to 12 inches. So far it's not going well.

I have two list boxes, named "firstmeasure" and "secondmeasure". For the purpose of this post we will use only 3 different unit in the list boxes, centimeters, feet, and inches. I also have two text boxes used to show the output and for the user to put in a number to convert. And of course, a button that calls the function (I'd prefer it to do the function automatically, but I'll get to that later).

I'm trying to use variable arrays and using the value of the list box options to define which value the array will use. Then in the function I'm trying to use a switch/case statement to allow it to figure out which numbers to plug into an equation.

My problem is that it seems to automatically go to the last case option regardless of what the list box is.

This is the form that in the HTML file:
Code:

<form action="" name="lengthform" id="lengthform" >
    <p>
      <label >Select first measurement</label>
      <br/>
      <select id="firstmeasure" name="firstmeasure" >
        <option value="1">Centimeter</option>
        <option value="2">Feet</option>
        <option value="3">Inch</option>
      </select>
      <input type="text" id="input" name="input" value="1" />
      <br/>
      <br/>
      <label >Select Second measurement</label>
      <br/>
      <select id="secondmeasure" name="secondmeasure" >
        <option value="1">Centimeter</option>
        <option value="2">Feet</option>
        <option value="3">Inch</option>
      </select>
      <input type="text" id="output" name="output" />
    </p>      
    <input type="button" onclick="calculate()" value="Convert!" />
</form>

This is whats in the Java file:
Code:

 var centimeters1 = new Array() ;
 centimeters1["1"] = "1" ; //centimeters
 centimeters1["2"] = "0.032808399" ; //feet
 centimeters1["3"] = "0.393700787" ; //inches

 var feet1 = new Array() ;
 feet1["1"] = "30.48" ; //centimeters
 feet1["2"] = "2" ; //feet
 feet1["3"] = "12" ; //inches

 var inches1 = new Array() ;
 inches1["1"] = "2.54" ; //centimeters
 inches1["2"] = "0.0833333333" ; //feet
 inches1["3"] = "3" ; //inches

function calculate() {	
var measure1 = document.lengthform.elements["firstmeasure"] ;
var measure2 = document.lengthform.elements["secondmeasure"] ;

var A = document.lengthform.input.value ;
var B ;
var C ;
	switch (measure1.value){	
		case "1" :
			B = centimeters1[measure2.value] ;
			C = A * B
	    	document.lengthform.output.value = C
		case "2" :
			B = feet1[measure2.value] ;
			C = A * B
			document.lengthform.output.value = C
		case "3" :
			B = inches1[measure2.value] ;
			C = A * B
			document.lengthform.output.value = C
	}//end switch
}//end function

So, measure1 reads the value of the first list box, and measure 2 reads the value of the second list box. I tried using a switch case statement instead of writing a ton of if statements. Which I also tried and it gave me the same problem.

If there is a much better way to do a conversion tool, than I would love to learn how. Any help on fixing this seemingly easy problem would be great.

Edit: Do I have to use an "int" variable in the switch statement? I'm using Adobe Dreamweaver and it won't allow to me to create a variable using "int", it just gives me a syntax error.

I'm trying to make my form both check that the e-mail's match and also be case insensitive when being submitted. I've figured out how to get the e-mail's to be checked to match, but can't figure out how to also make it not case sensitive. Help!

This is what I have so far...
Code:

<head>
<script type = "text/javascript">

function checkSame() {
var emval1 = document.cform.email.value;
var emval2 = document.cform.confirm.value;
if ((emval1 != emval2) || (emval1 == "") || (emval2 == "")) {
alert ("The two email addresses do not match - please re-enter them");
document.cform.email.value = "E-mail:";
document.cform.confirm.value = "Confirm Email:";
setTimeout("document.cform.email.focus()", 25);
return false;
}
return true;
}

function toLowerCase() {
var one = document.cform.email.value.toLowerCase();
var another = document.cform.confirm.value.toLowerCase();
if (one == another) return true;
alert("Both fields must be identical.");
return false;
}

</script>

Hi, I am a beginner in programming however I am close to completing this task for my uni course and I know what method is needed "toLowerCase()" yet I am not sure on where it needs to be placed.
If i paste in the question and then the coding I have done so far any helped would be greatly appreciated.

Thanks in advance to everyone who replies


QUESTION:
function findAnyU(s) - to discover if string s appears in any of the URLs in the array pages. Gives an alert of s together with 'found' or 'not found' as for find1C. [Note that the search should be case insensitive so that 'lboro' and 'Lboro' and 'LBORO' would all be found in 'www.lboro.ac.uk' - all remaining functions should also be case insensitive in this way]

Example call: findAnyU("Lboro")
Example result: "Lboro" found

MY CODING...

var pages = [
"[www.lboro.ac.uk] Loughborough University offers degree programmes and world class research.",
"[www.XXXX.ac.uk] Loughborough University offers degree programmes and world class research. "
];

function findAnyU (s){

for(i=1;i<pages.length;i++)
{
var a = '"'+s+'"';
var b = pages[i].indexOf('[');
var l = pages[i].indexOf(']');
var t = pages[i].substr(b+1, l);
var c = t.indexOf(s);
}
if (c>=0)
a+= ' found'
else
a+= ' not found'

return (a)
}

alert(findAnyU("Lboro"));

Thanks Again Everyone X

This has always puzzled me:

Code:

foo="bar";

switch(foo) {
	case "bar": {
		alert("a");
	}

	case 123: {
		alert("b");
	}
}

"a" is displayed because foo=="bar", but even if execution continues to the next block, surely "b" shouldn't be displayed because foo!=123?

Does anyone know what the logic behind this is?
