Switch Statements And Variables - Creating Bars?
Apr 18, 2011
I'm having some trouble with the Switch Statements. My program runs without it so I know that the problem is here. I believe the logic is sound so it may be due to incorrect syntax. The purpose of this function is to create bars, and the length of the bars is determined by the value of the "percent" variable (which is working fine) in the For loop after the Switch statements. The variable, "partyType" contains any of the text strings, such as "I", "D", etc.
function createBar(partyType,percent){
var barText;
switch(partyType){
case "D":
barText="<td class='dem'></td>";
break;
case "R":
barText="<td class='rep'></td>";
break;
case "I":
barText="<td class='ind'></td>";
break;
case "G":
barText="<td class='green'></td>";
break;
case "L":
barText="<td class='lib'></td>";
break;
default: document.write("hi");
}
for(var i=1; i<percent; i++){
document.write(barText);
}}}

I am trying to write a multiple-choice quiz for my chemistry class where ten questions are selected randomly from a block of about 100; then I want the students to click a button and grade their quiz. I have stored the questions in an array named Q and each radio button has a name property corresponding to the array entry (the buttons in Q[1] have the name Q1, etc.). I generate the exam in the body of the page between form tags using a document.write statement and all of the questions and buttons appear properly. I cannot, however, figure out how to get the value of the button that has been checked for the randomly selected questions.
As the questions are selected, I record the question number as a variable; for example �Qnumber1 = Q(random_num)�. The variable does, in fact, have the proper value (for example Q1) but when I try to read the value of the radio buttons in the Q1 set using:
document.form1.Qnumber1[0].value
it doesnt work!

Any way to create a presentation on a website WITHOUT showing load bars? Background info: it is about photography website where someone after seeing full size picture could click to view it in a room setting. Right now my developer created a presentation where full size picture zooms out then there is a load bar (hideous) and then the presentation starts. So it looks like it is 2 different parts and I would like to make it into one smooth presentation. Btw: would like if possible avoid flash animation due to recent developments on Apple's side.

Currently I have the following script:-
function validate_form(){
if(regform.reguser.value == ""){
alert("Please completed the selected box");[code]....
to validate a simple registration form, however I initially tried to streamline this function by cycling through an array using a loop to point to various input elements in the HTML page itself. I found that when trying to use a variable in the aforementioned if statements the javascript failed to work i.e.
var test = "reguser";
if(regform.test.value = ""){
}
I know the javascript is looking for the input element "test" instead of "reguser" but is there any way I can force it to look for the contents of the variable.

I'm trying to code a script that will display an approximate postage price based on different combinations of variables, but the numbers I defined for each case aren't reflected in the text box. I'm using a switch statement for all the different combinations of options, which the user will choose by selecting check-boxes. (Additionally, I know that this code probably isn't a very efficient way of doing what I'm doing - how to improve it.) I've attached all the relevant parts of the code, including how I defined variables originally.
<script type="text/javascript">
function count(){
var firstclass = document.calc.firstclass.value;
var postcard = document.calc.firstclass.value;
var numpages = document.calc.numpages.value;
var nms = document.calc.nms.value;
var large = document.calc.large.value;
var numpages = parseInt(document.calc.numpages.value); .....

Im creating a switch statement for this case, but dont know how to start - Create a Switch statement that tests the value of the partyType parameter. If partyType equals "D", store the following text string in a variable named barText: <td class='dem'> </td>
If partyType equals "R", barText should equal <td class='rep'> </td> etc.. So since its going to test the value of the partyType parameter, and store the text string in a variable named barText do i begin like:

how you would piece
together a variable name and then assign it a value. I want to create a
hidden field and assign it a value based on the value of another variable
Right now it looks like:
("document.all.SM_MARK_10" + dateNumber + ".value")
where dateNumber is an already defined integer. What I want is to say
document.all.SM_MARK_1001.value="XX"
document.all.SM_MARK_1002.value="X2"
etc.
based on that value of dateNumber. Any way to do this easily?

I have a flash object count down clock, that uses the following:
value="server={NOW}&localtime={LOCALNOW}
I need to somehow put the server time and localtime into a javascript to use with the above. The variables should be in Unix time. Does that some sense? I'm starting to google out some javascript time examples, but haven't quite gotten it figured out yet. I think its probably alot simpler than I'm making it out to be.

I'm trying to create a family tree online that has several other related family charts. I want each person's name and birth year to be stored in javascript variables, then I want to be able to just go through the tree, and put the persons name once, and have it put the appropriate name and birthyear in the little boxes that the css is creating.
var johnname = "John Smith";
var johnbirthyear = "Jan 1 1930";
var janename = "Jane Doe";
[code]....
So I thought I had it all figured out. I thought that the above would take the id of John that I added, go to the line that sets the name, add john to the word name, and then document write the variable of johnname from the js file. I know you're laughing at me because of course it instead made the value of name to johnname, then wrote the word johnname in the box. I want to go through and be able to just type the persons name in the html for that box once, and have it update with their appropriate info.

I have an e-commerce site which is hosted and I'm not allowed to place any server side script on, nor am I allowed to access any server side variables. I need to be able to create variables based on page content (i.e. order total, products, quantities) and send them to my web analytics program.
Does anyone know if this is possible?? Or do you have any idea how I can gather the information that I need?

how to store variables in cookies so that I can later use them in php code.Here is the basic javascript I want to use:
Code:
function alertSize() {
var myWidth = 0, myHeight = 0;
if( typeof( window.innerWidth ) == 'number' ) {[code]....
Now, I want to save myWidth and myHeight in a cookie(s) but I don't know how to. The window.alert() will only be for testing purposes and will not be needed in the final code. I also need to know if the codes need to be in certain sections such as <head>, etc.]

I am sure if I searched long enough I could find the answer, but to save time I would appreciate help with the # statements, such as #include, #csstopmenu, etc which I find in the scripts here and elsewhere. I know that #include is used with shtml to include another html page. What are the others? Is there a definitive list, and if so where can I find it?

ifIll();
}

I need to test the contents of three fields to validate which contain text, and based on the results, set additional variables. I'm sure this is falling off the log simple, and I got it to work in PHP, but am having problems getting the syntax correct in Javascript.
In a nutshell, if a front AND a rear msg is entered, the price is $115, else the price is $80. I'm sure there's an easier way to code this than what I've done, but I don't know how to correctly perform several && and || in the same comparison.
Here's the PHP...
function notEmpty(){
var FrontMsgTxtTop = document.getElementById('FrontMsgTxtTop').value;
var FrontMsgTxtBottom = document.getElementById('FrontMsgTxtBottom').value;
var RearMsgTxt = document.getElementById('RearMsgTxt').value;
[Code]....

<script language="javascript">
<!--
self.location.href='#add'
document.addform.txtTitle.focus();
//-->
</script>
the self.location.href='#add' goes to a html anchor on the page, and the focus is supposed to set the cursor inside the first textbox when the statement is run.
if i run it as is, it will go to the anchor like its supposed to, but won't put the cursor in the textbox. if i comment out the first statement, it will put the focus on the textbox.

I have a very simple script that generates a prompt window. Instead of using a default text, I have left the text field empty. However, I would like a default message to display in the pop up window if the user does not enter a value in the prompt box before clicking okay. I tried adding a conditional statement but the default text does not write in the pop up window.
Here is the code:
Code:
function promptBox(){
var message = prompt("Who is your favorite Hollywood Star?", "");
newWindow = window.open('','','width=800,height=600');
newWindow.document.write(message);
newWindow.focus();
if ((prompt) == null);
document.write("No Value Entered");
}

I try to figure out how I can merge two onclick in one: The one is opening a "lightbox" div with a fullsize view. Now I would like to count this click with loading a site in an iframe. I am not that known in javascript, therefore my question: Is it possible?
This would load the iframe:
PHP Code:
onclick=parent.fullsize.location='[URL]';
This is the onclick statement in the lightbox.js:
PHP Code:
anchor.onclick=self._genOpener(num)}var body=d.getElementsByTagName("body")[0];
Separated the both onclick are not working. How I can put them together in one onclick? I tried this, but it is not working:
PHP Code:
anchor.onclick=self._genOpener(num)}var body=d.getElementsByTagName("body")[0] && parent.fullsize.location='[URL]';

The jQuery isn't working when calling elements placed in conditional statements. My sample code is shown below. This code works beautiful if the if/else conditions aren't there. What is the problem? Is there something wrong with my code? Is there a workaround? I absolutely need to use a conditional statement in my production code.

I have a series of videos which must be loaded dynamically on their pages which then get loaded into an iframe. I need to be able to load these videos using variables for the width and height. It's imperative that I use variables as the sizes of the movies will be determined by the user's resolution.
Here's the code I'm currently using <script type="text/javascript">
var dimW = screen.width;
var dimH = screen.height;
var w1 = dimW.toString();
var h1 = dimH.toString();
document.write('<OBJECT ID="Player" width="'+w1+'" height="'+h1+'" CLASSID="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" style=border:0px;">
'); .....
I'm developing in xhtml so naturally, IE doesn't recognize the document.write statements and the page comes up blank in IE. It works flawlessly in FireFox (as expected). So, I need to replace the document.write statements with something else while still being able to pass variables for the movie objects height & width.
I've tried this code: <script type="text/javascript">
//alert("The beginning");
var dimW = window.innerWidth;
var dimH = window.innerHeight;
var w1 = dimW.toString();
var h1 = dimH.toString(); .....
document.getElementById('mediaPlayer').appendChild(theNewMovie);
</script>. I then have a <td> with the id of "mediaPlayer" but nothing is showing up. Most likely because I'm still fairly new to javascript and am probably forgetting or overlooking something.
